Switch management and discovery

overview

The switch provides administrative management options that let you configure, monitor, and

control the network. Using the local browser interface, you can configure the switch and the

network, including the ports, the management VLAN, VLANs for traffic control, link

aggregation for increased bandwidth, quality of service (QoS) for prioritizing traffic, and

network security.

Initial discovery of the switch on the network requires one of the following tools:

• NETGEAR Smart Control Center (SCC) program. The SCC runs on a Windows-based

computer. You can download the SCC program from netgear.com/support/download/.

For more information about the SCC program see Discover a switch in a network with a

DHCP server on page 14 and Discover a switch in a network without a DHCP server on

page 15.

• NETGEAR Switch Discovery Tool. If you use a Mac computer, you can use the

NETGEAR Switch Discovery Tool to discover the switch in your network and access the

local browser interface of the switch. For more information about the Switch Discovery

Tool, Use the NETGEAR Switch Discovery Tool to access the switch on page 17.

• NETGEAR Insight app. You can also install the NETGEAR Insight app on an iOS or

Android mobile device and discover the IP address of the switch. For more information

about the Insight app, see Use the NETGEAR Insight app to discover and register the

switch on page 18.

You can also get the IP address of the switch from the DHCP server in the network or use an

IP scanner utility.

After discovery, you can configure the switch using the local browser interface for advanced

setup and configuration of features, or the SCC program for very basic setup. For more

information, see the SCC user manual, which you can download from

netgear.com/support/download/.

Change the default IP address of the switch

To enable remote management of the switch through a web browser or SNMP, connect the

switch to the network and specify an IP address, subnet mask, and default gateway. The

switch default IP address is 192.168.0.239 and the default subnet mask is 255.255.255.0.

To change the default IP address of the switch, use one of the following methods:

• Dynamic assignment through DHCP. DHCP is enabled on the switch by default. If you

connect the switch to a network with a DHCP server, the switch obtains its network

information automatically. You can use the Smart Control Center to discover the

8-Port or 16-Port Gigabit Smart Managed Pro Switch Model GS418TPP, GS510TLP, and GS510TPP

Get Started User Manual14

automatically assigned network information. For more information, see Discover or

change the switch IP address on page 14.

• Static assignment through the Smart Control Center. If you connect the switch to a

network that does not include a DHCP server, you can use the Smart Control Center to

assign a static IP address, subnet mask, and default gateway. For more information, see

Discover a switch in a network without a DHCP server on page 15.

• Static assignment by connecting from a local host. If you do not want to use the

Smart Control Center to assign a static address, you can connect to the switch from a

host (administrative system) in the 192.168.0.0/24 network and change the settings by

using the local browser interface on the switch. For information about how to set the IP

address on the administrative system so that it is in the same subnet as the default IP

address of the switch, see Configure a static IP address from a directly connected

computer on page 19.

Discover or change the switch IP address

The following sections describe methods that let you discover or change the IP address of

the switch.

Discover a switch in a network with a DHCP server

This section describes how to set up your switch in a network that includes a DHCP server.

The DHCP client on the switch is enabled by default. When you connect the switch to your

network, the DHCP server automatically assigns an IP address to the switch. Use the Smart

Control Center (SCC) to discover the IP address automatically assigned to the switch.

Note: For more information about the SCC program, see the SCC user manual,

which you can download by visiting netgear.com/support/download/.

To install the switch in a network with a DHCP server:

1. Connect the switch to a network with a DHCP server.

2. Power on the switch by connecting its power cord.

3. Install the Smart Control Center on your computer.

4. Start the Smart Control Center.

5. Click the Discover button for the Smart Control Center to discover all the devices in the

subnet.

6. Make a note of the displayed IP address assigned by the DHCP server.

You can use this address later to access the switch directly from a web browser (that is,

without using the Smart Control Center).

7. Select your switch by clicking the line that displays the switch.

8. Click the Web Browser Access button.

The Smart Control Center launches a browser that displays the login page of the selected

device.

Use your web browser to manage your switch. The default password is password. For

more information about the page layout and options, see Navigation tabs, configuration

menus, and page menu on page 22.

This section describes how to use the Smart Control Center to set up your switch in a

network without a DHCP server. If your network does not include a DHCP service, you must

assign a static IP address to your switch.

If you prefer, you can assign the switch a static IP address even if your network does include

a DHCP server.

Use the NETGEAR Switch Discovery Tool to access the

switch

For easiest access, we recommend that you cable the switch to a network with a router or

DHCP server that assigns IP addresses, power on the switch, and then use a computer that

is connected to the same network as the switch.

The NETGEAR Switch Discovery Tool lets you discover the switch in your network and

access the local browser interface of the switch from a Mac or a 64-bit Windows-based

computer.

To install the NETGEAR Switch Discovery Tool, discover the switch in your network,

and access the local browser interface of the switch:

1. Download the Switch Discovery Tool by visiting

netgear.com/support/product/netgear-switch-discovery-tool.aspx.

Depending on the computer that you are using, download either the Mac version or the

version for a 64-bit Windows-based computer.

2. Temporarily disable the firewall, Internet security, antivirus programs, or all of these on the

computer that you use to configure the switch.

3. Unzip the Switch Discovery Tool files, double-click the .exe or .dmg file (for example,

NETGEAR+Switch+Discovery+Tool+Setup+1.2.101.exe or

NetgearSDT-V1.2.101.dmg), and install the program on your computer.

The installation process places a NETGEAR Switch Discovery Tool icon on your

desktop.

4. Reenable the security services on your computer.

5. Power on the switch.

The DHCP server assigns the switch an IP address.

6. Connect your computer to the same network as the switch.

Configure a static IP address from a directly connected

computer

If you do not want to use the Smart Control Center to configure the network information on

the switch, you can change the IP address of the switch by connecting an Ethernet cable

from a computer to the switch.The IP address of the computer must be in the same subnet as

the default IP address on the switch. For most networks, this means that you must change

the IP address of the computer to be on the same subnet as the default IP address of the

switch (192.168.0.239).

To configure a static IP address on the switch:

1. Change the IP settings of your computer to be in the same subnet as the IP settings of

the switch.

If the DHCP client of the switch is enabled and you remove the switch from the network

with the DHCP server, the IP address reverts to the default IP address of 192.168.0.239

with a subnet of 255.255.255.0.

Note: If you already disabled the DHCP client and assigned a static IP

address to the switch, change the IP settings of your computer to be in

the same subnet as the static IP address.

For more information about changing the IP settings on your computer, see one of the

following knowledge base articles at the NETGEAR website:

• Windows-based computer. See the following article:

https://kb.netgear.com/27476/How-to-set-a-static-IP-address-in-Windows

Configure an SNTP server

SNTP assures accurate network device clock time synchronization up to the millisecond.

Time synchronization is performed by a network SNTP server. The switch operates only as

an SNTP client and cannot provide time services to other systems.

Time sources are established by strata. Strata define the accuracy of the reference clock.

The higher the stratum (where zero is the highest), the more accurate the clock. The device

receives time from Stratum 1 and above since it is itself a Stratum 2 device.

Last Attempt Status The status of the last SNTP request or unsolicited message for both unicast

and broadcast modes. If no message was received from a server, a status of

Other is displayed. These values are appropriate for all operational modes.

• Other. The status of the last request is unknown.

• Success. The SNTP operation was successful and the system time was

updated.

• Request Timed Out. After an SNTP request was sent to an SNTP server,

the response timer expired before a response from the server was

received.

• Bad Date Encoded. The time provided by the SNTP server is not valid.

• Version Not Supported. The SNTP version supported by the server is

not compatible with the version supported by the client.

• Server Unsynchronized. The SNTP server is not synchronized with its

peers. This is indicated by the leap indicator field in the SNTP message.

• Server Kiss Of Death. The SNTP server indicated that no further queries

were to be sent to this server. This is indicated by a stratum field equal to

0 in a message received from a server.

Server IP Address The IP address of the server for the last received valid packet. If no message

was received from any server, an empty string is shown.

Address Type The address type of the SNTP server address for the last received valid

packet.

Server Stratum The claimed stratum of the server for the last received valid packet.

Reference Clock ID The reference clock identifier of the server for the last received valid packet.

Server mode The mode of the server for the last received valid packet.

Unicast Server Max Entries The maximum number of unicast server entries that can be configured on this

client.

Unicast Server Current Entries The number of current valid unicast server entries configured for this client.

Broadcast Count The number of unsolicited broadcast SNTP messages that were received and

processed by the SNTP client since the last reboot.

Field Description

8-Port or 16-Port Gigabit Smart Managed Pro Switch Model GS418TPP, GS510TLP, and GS510TPP

Configure System Information User Manual57

The following is an example of strata:

• Stratum 0. A real-time clock is used as the time source, for example, a GPS system.

• Stratum 1. A server that is directly linked to a Stratum 0 time source is used. Stratum 1

time servers provide primary network time standards.

• Stratum 2. The time source is distanced from the Stratum 1 server over a network path.

For example, a Stratum 2 server receives the time over a network link, through NTP, from

a Stratum 1 server.

Information received from SNTP servers is evaluated based on the time level and server

type.

SNTP time definitions are assessed and determined by the following time levels:

•T1. Time that the original request was sent by the client.

•T2. Time that the original request was received by the server.

•T

3. Time that the server sent a reply.

•T

4. Time that the client received the server's reply.

The device can poll unicast server types for the server time.

Polling for unicast information is used for polling a server for which the IP address is known.

SNTP servers that were configured on the device are the only ones that are polled for

synchronization information. T1 through T4 are used to determine server time. This is the

preferred method for synchronizing device time because it is the most secure method. If this

method is selected, SNTP information is accepted only from SNTP servers defined on the

device using the SNTP Server Configuration page.

The device retrieves synchronization information, either by actively requesting information or

at every poll interval.

You can view and modify information for adding and modifying Simple Network Time

Protocol SNTP servers.

Add an SNTP server

To add an SNTP server:

1. Connect your computer to the same network as the switch.

You can use a WiFi or wired connection to connect your computer to the network, or

connect directly to a switch that is off-network using an Ethernet cable.

2. Launch a web browser.

3. In the address field of your web browser, enter the IP address of the switch.

If you do not know the IP address of the switch, see Change the default IP address of

the switch on page 13.

The login window opens.

4. Enter the switch’s password in the Password field.

8-Port or 16-Port Gigabit Smart Managed Pro Switch Model GS418TPP, GS510TLP, and GS510TPP

Configure System Information User Manual58

The default password is password.

The System Information page displays.

5. Select System > Management > Time > SNTP Server Configuration.

6. From the Server Type menu, select the type of SNTP address to enter in the address field.

The address can be either an IP address (IPv4, IPv6) or a host name (DNS). The default

value is IPv4.

7. In the Address field, specify the IP address or the host name of the SNTP server.

This is a text string of up to 64 characters, containing the encoded unicast IP address or

host name of an SNTP server. Unicast SNTP requests are sent to this address. If this

address is a DNS host name, then that host name is resolved into an IP address each

time an SNTP request is sent to it.

8. If the UDP port on the SNTP server to which SNTP requests are sent is not the standard

port (123), specify the port number in the Port field.

The valid range is 1 to 65535. The default value is 123.

9. In Priority field, specify the priority order which to query the servers.

The SNTP client on the device continues sending SNTP requests to different servers until

a successful response is received, or all servers are exhausted. The priority indicates the

order in which to query the servers. The request is sent to an SNTP server with a priority

value of 1 first, then to a server with a priority value of 2, and so on. If any servers are

assigned the same priority, the SNTP client contacts the servers in the order that they

appear in the table. The valid range is 1 to 3. The default value is 1.

10. In the Version field, specify the NTP version running on the server.

The range is 1 to 4. The default value is 4.

11. Click the Add button.

The SNTP server entry is added.

12. Repeat the previous steps to add additional SNTP servers.

You can configure up to three SNTP servers.

5. Select System > Management > Green Ethernet > Green Ethernet Configuration.

6. Select the Auto Power Down Mode Disable or Enable radio button.

By default, this mode is disabled. When a port link is down, the underlying physical layer

goes down for a short period and then checks for port link pulses again so that

auto-negotiation remains possible. In this way, the switch saves power when no link

partner is present for the port.

7. Select the EEE Mode Disable or Enable radio button.

By default, this mode is disabled. Energy Efficient Ethernet (EEE) combines the MAC with

a family of physical layers that support operation in a low power mode. It is defined by the

IEEE 802.3az standard. Lower power mode enables both the send and receive sides of

the link to disable some functionality for power savings when lightly loaded. Transition to

low power mode does not change the link status. Frames in transit are not dropped or

corrupted in transition to and from low power mode. Transition time is transparent to

upper layer protocols and applications.

7. From the Port Power menu, select the administrative PoE mode of the port:

• Enable. The port’s capacity to deliver power is enabled. This is the default setting.

• Disable. The port’s capacity to deliver power is disabled.

8. From the Port Priority menu, select the priority for the port in relation to other ports if the

total power that the switch is capable of delivering exceeds the total power budget:

• Low. Low priority. This is the default setting.

• Medium. Medium priority.

•High. High priority.

•Critical. Critical priority.

The port priority determines which ports can still deliver power after the total power

delivered by the switch exceeds the total power budget. (In such a situation, the switch

might not be able to deliver power to all connected devices.) If the same priority applies to

two ports, the lower-numbered port receives higher priority.

9. From the Power Mode menu, select the PoE mode that the port must function in:

• 802.3af. The port is powered in and limited to the IEEE 802.3af mode. A PD that

requires IEEE 802.3at does not receive power if the port functions in IEEE 802.3af

mode.

• Legacy. The port is powered using high-inrush current, which is used by legacy PDs

that require more than 15W to power up.

•Pre-802.3at. The port is initially powered in the IEEE 802.3af mode and, before

75 msec pass, is switched to the high power IEEE 802.3at mode. Select this mode if

the PD does not perform Layer 2 classification or if the switch performs

2-event Layer 1 classification.

•802.3at. The port is powered in the IEEE 802.3at mode and is backward compatible

with IEEE 802.3af. The 802.3at mode is the default mode. In this mode, if the switch

detects that the attached PD requests more power than IEEE 802.3af but is not an

IEEE 802.3at Class 4 device, the PD does not receive power from the switch.

10. From the Power Limit Type menu, select how the port controls the maximum power that it

can deliver:

•None. The port draws up to Class 0 maximum power in low power mode and up to

Class 4 maximum power in high power mode.

•Class. The port power limit is equal to the class of the attached PD.

•User. The port power limit is equal to the value that is specified in the Power Limit

(mW) field. This is the default setting.

Note: If a PD does not report its class correctly, use of these options can

preserve additional PoE power by preventing the switch from

delivering more power than the PD requires. However, depending on

which option you select, a PD that does not report its class correctly

might not power up at all.

11. In the Power Limit (mW) field, enter the maximum power (in mW) that the port can deliver.

as follows:

• No Error. The port is not in any error state and can provide power.

• MPS Absent. The port detected the absence of the main power supply,

preventing the port from providing power.

• Short. The port detected a short circuit condition, preventing the port from

providing power.

• Overload. The PD that is connected to the port attempts to draw more power

than allowed by the port’s settings, preventing the port from providing power at

all.

• Power Denied. The port was denied power because of a shortage of power or

because of an administrative condition. In this condition, the port cannot

provide power.

Configure LLDP

The IEEE 802.1AB-defined standard, Link Layer Discovery Protocol (LLDP), allows stations

on an 802 LAN to advertise major capabilities and physical descriptions. This information is

viewed by a network manager to identify system topology and detect bad configurations on

the LAN.

LLDP is a one-way protocol without any request/response sequences. Information is

advertised by stations implementing the transmit function, and is received and processed by

stations implementing the receive function. The transmit and receive functions can be

enabled or disabled separately per port. By default, both transmit and receive are disabled on

all ports. The application is responsible for starting each transmit and receive state machine

appropriately, based on the configured status and operational state of the port.

The Link Layer Discovery Protocol-Media Endpoint Discovery (LLDP-MED) is an

enhancement to LLDP with the following features:

•Autodiscovery of LAN policies (such as VLAN, Layer 2 priority, and DiffServ settings),

enabling plug and play networking.

•Device location discovery for creation of location databases.

•Extended and automated power management of Power over Ethernet endpoints.

•Inventory management, enabling network administrators to track their network devices

and determine their characteristics (manufacturer, software and hardware versions,

serial/asset number).

Configure the LLDP global settings

You can specify the global LLDP and LLDP-MED settings that are applied to the switch.

To configure the global LLDP settings:

options:

• TLV Advertised Interval. The number of seconds between transmissions of LLDP

advertisements.

• Hold Multiplier . The transmit interval multiplier value, where transmit hold multiplier ×

transmit interval = the time to live (TTL) value that the device advertises to neighbors.

• Re-initializing Delay. The number of seconds to wait before attempting to re-initialize

LLDP on a port after the LLDP operating mode on the port changes.

• Transmit Delay. The minimum number of seconds to wait between transmissions of

remote data change notifications to one or more SNMP trap receivers configured on

the switch.

7. To configure a nondefault value for LLDP-MED, enter a value in the Fast Start Duration

field.

This value sets the number of LLDP packets sent when the LLDP-MED fast start

mechanism is initialized, which occurs when a new endpoint device links with the

Configure a DHCP L2 relay, DHCP

snooping, and dynamic ARP inspection

The switch supports a DHCP L2 relay, DHCP snooping, and Dynamic ARP Inspection (DAI).

DHCP snooping and DAI are Layer 2 security features that examine traffic to help prevent

accidental and malicious attacks on the switch or network.

Configure a DHCP L2 relay

DHCP relay agents eliminate the need to connect to a DHCP server on each physical

network. Relay agents populate the giaddr field and also append the Relay Agent Information

option to the DHCP messages. DHCP servers use this option for IP addresses and

assignment policies for other settings. These DHCP relay agents are typically IP

routing-aware devices and are referred to as Layer 3 relay agents. In some network

configurations, a need might exist for Layer 2 devices to append the Relay Agent Information

option as they are closer to the end hosts.

These Layer 2 devices typically operate only as bridges for the network and might not include

an IPv4 address on the network. Lacking a valid IPv4 source address, they cannot relay

packets directly to a DHCP server located on another network. These Layer 2 devices

append the Relay Agent Information option and broadcast the DHCP message.

Configure DHCP snooping

DHCP snooping is a useful feature that provides security by filtering untrusted DHCP

messages and by building and maintaining a DHCP snooping binding table. An untrusted

message is a message that is received from outside the network or firewall and that can

cause traffic attacks within your network. The DHCP snooping binding table contains the

MAC address, IP address, lease time, binding type, VLAN number, and interface information

that corresponds to the local untrusted interfaces of a switch. An untrusted interface is an

interface that is configured to receive messages from outside the network or firewall. A

trusted interface is an interface that is configured to receive only messages from within the

network.

DHCP snooping acts like a firewall between untrusted hosts and DHCP servers. It also

provides way to differentiate between untrusted interfaces connected to the end user and

trusted interfaces connected to the DHCP server or another switch.

Manage dynamic ARP Inspection

Dynamic ARP Inspection (DAI) is a security feature that rejects invalid and malicious ARP

packets. DAI prevents a class of man-in-the-middle attacks where an unfriendly station

intercepts traffic for other stations by poisoning the ARP caches of its unsuspecting

neighbors. The malicious attacker sends ARP requests or responses mapping another

station’s IP address to its own MAC address.

When DAI is enabled, the switch drops ARP packets whose sender MAC address and

sender IP address do not match an entry in the DHCP snooping bindings database. You can

optionally configure additional ARP packet validation.

When DAI is enabled on a VLAN, DAI is enabled on the interfaces (physical ports or LAGs)

that are members of that VLAN. Individual interfaces are configured as trusted or untrusted.

The trust configuration for DAI is independent of the trust configuration for DHCP snooping.

Configure dynamic ARP inspection globally

If you configure the source MAC address validation option, DAI verifies that the sender MAC

address in an ARP packet equals the source MAC address in the Ethernet header.

The Ethernet header includes a configurable option to verify that the target MAC address in

the ARP packet equals the destination MAC address. This check applies only to ARP

responses, since the target MAC address is unspecified in ARP requests. You can also

enable IP address checking. When this option is enabled, DAI drops ARP packets with an

invalid IP address. The following IP addresses are considered invalid:

•0.0.0.0

•255.255.255.255

•All IP multicast addresses

•All class E addresses (240.0.0.0/4)

•Loopback addresses (in the range 127.0.0.0/8)

8-Port or 16-Port Gigabit Smart Managed Pro Switch Model GS418TPP, GS510TLP, and GS510TPP

Configure System Information User Manual116

The valid IP check is applied only on the sender IP address in ARP packets. In ARP

response packets, the check is applied only on the target IP address.

To configure the optional DAI features:

1. Connect your computer to the same network as the switch.

You can use a WiFi or wired connection to connect your computer to the network, or

connect directly to a switch that is off-network using an Ethernet cable.

2. Launch a web browser.

Configure dynamic ARP inspection for a VLAN

In this example, DAI is enabled on VLAN 1. Ports 1–10 connect end users to the network and

are members of VLAN 1. These ports are configured to limit the maximum number of ARP

packets with a rate limit of 10 packets per second. LAG 1, which is also a member of VLAN 1

and contains ports 11–14, is the trunk port that connects the switch to the data center, so it is

configured as a trusted port.

Configure a dynamic ARP inspection ACL

DAI relies on the information in the DHCP snooping bindings database to validate ARP

packets. For networks that use static IP addresses and do not use DHCP, DAI access control

lists (ACLs) can be used to statically map an IP address to a MAC address on a VLAN. When

hosts use static IP addresses, the DHCP snooping feature cannot build a bindings database.

DAI ACLs are also useful when other switches in the network do not run DAI.

DAI consults the static mappings configured in the DAI ACLs before it consults the DHCP

snooping bindings database; thus static mappings receive precedence over DHCP snooping

bindings. If the static flag is enabled on a VLAN, DAI consults the DAI ACL only and does not

validate ARP information against the DHCP snooping bindings database.

To configure a dynamic ARP inspection ACL with three rules and associate it with

Note: After you change the autonegotiation mode, the switch might be

inaccessible for a number of seconds while the new settings take

effect.

11. In the Speed field, specify the speed value for the selected port.

Possible field values are as follows:

• Auto. All supported speeds.

•1

0. 10 Mbits/second

• 100. 100 Mbits/second

The delimiter characters for setting different speed values are a comma (,), a period (.)

The range is 1500 to 9198. The default maximum frame size is 1500.

15. From the Flow Control menu, select the configuration for IEEE 802.3 flow control.

• Disable. If the port buffers become full, the switch does not send pause frames, and

data loss could occur. This is the default setting.

• Symmetric. If the port buffers become full, the switch sends pause frames to stop

traffic.

Flow control helps to prevent data loss when the port cannot keep up with the number

of frames being switched. When you enable flow control, the switch can send a pause

frame to stop traffic on the port if the amount of memory used by the packets on the

port exceeds a preconfigured threshold and responds to pause requests from partner

devices. The paused port does not forward packets for the time that is specified in the

pause frame. When the pause frame time elapses, or the utilization returns to a

specified low threshold, the switch enables the port to again transmit frames. The

switch also honors incoming pause frames by temporarily halting transmission.

• Asymmetric. If the port buffers become full, the switch does not send pause frames,

and data loss could occur . However , the switch does honor incoming pause frames by

temporarily halting transmission.

Note: For LAG interfaces, flow control mode is displayed as a blank field

because flow control is not applicable.

Configure Switching User Manual134

Configure link aggregation groups

Link aggregation groups (LAGs), which are also known as port channels, allow you to

combine multiple full-duplex Ethernet links into a single logical link. Network devices treat the

aggregation as if it were a single link, which increases fault tolerance and provides load

sharing. You assign the LAG VLAN membership after you create a LAG. The LAG by default

becomes a member of the default management VLAN (that is, VLAN 1).

A LAG interface can be either static or dynamic, but not both. All members of a LAG must

participate in the same protocols. A static port channel interface does not require a partner

system to be able to aggregate its member ports.

The switch supports static LAGs. When a port is added to a LAG as a static member, the port

neither transmits nor receives LACPDUs.

Model GS418TPP supports eight LAGs. Models GS510TLP and GS510TPP support five

LAGs.

Configure the LAG settings

You can group one or more full-duplex Ethernet links to be aggregated together to form a link

aggregation group, which is also known as a port channel. The switch treats the LAG as if it

were a single link.

To configure the LAG settings:

1. Connect your computer to the same network as the switch.

You can use a WiFi or wired connection to connect your computer to the network, or

connect directly to a switch that is off-network using an Ethernet cable.

2. Launch a web browser.

8. From the Admin Mode menu, select Enable or Disable.

When the LAG is disabled, no traffic flows and LACPDUs are dropped, but the links that

form the LAG are not released. The default is Enable.

9. From the Hash Mode menu, select the load-balancing mode for a port channel (LAG):

• 1 Src MAC, VLAN, EType, incoming port. This mode uses the source MAC

address, VLAN, EtherType, and incoming port that are associated with the packet.

•2 Dest MAC, VLAN, EType, incoming port. This mode uses the destination MAC

address, VLAN, EtherType, and incoming port that are associated with the packet.

•3 Src/Dest MAC, VLAN, EType, incoming port. This mode uses the source and

destination MAC addresses, VLAN, EtherT ype, and incoming port that are associated

with the packet. This is the default mode.

• 4 Src IP and Src TCP/UDP Port Fields. This mode uses the source IP address and

source TCP or UDP port value that are associated with the packet.

•5 Dest IP and Dest TCP/UDP Port Fields. This mode uses the destination IP

address and destination TCP or UDP port value that are associated with the packet.

•6 Src/Dest IP and TCP/UDP Port Fields. This mode uses the source and destination

IP addresses and source and destination TCP or UDP port values that are associated

with the packet.

Note: The switch balances traffic on a port channel (LAG) by selecting one

of the links in the channel over which packets must be transmitted. The

switch selects the link by creating a binary pattern from selected fields

in a packet and associating that pattern with a particular link.

10. From the STP Mode menu, select the Spanning Tree Protocol (STP) administrative mode

associated with the LAG. The possible values are as follows:

• Disable. Spanning tree is disabled for this LAG.

• Enable. Spanning tree is enabled for this LAG. Enable is the default.

Configure VLANs

Adding virtual LAN (VLAN) support to a Layer 2 switch offers some of the benefits of both

bridging and routing. Like a bridge, a VLAN switch forwards traffic based on the Layer 2

header, which is fast, and like a router, it partitions the network into logical segments, which

provides better administration, security, and management of multicast traffic.

By default, all ports on the switch are in the same broadcast domain. VLANs electronically

separate ports on the same switch into separate broadcast domains so that broadcast

packets are not sent to all the ports on a single switch. When you use a VLAN, users can be

grouped by logical function instead of physical location.

Each VLAN in a network is assigned an associated VLAN ID, which appears in the IEEE

802.1Q tag in the Layer 2 header of packets transmitted on a VLAN. An end station can omit

the tag, or the VLAN portion of the tag, in which case the first switch port to receive the

8-Port or 16-Port Gigabit Smart Managed Pro Switch Model GS418TPP, GS510TLP, and GS510TPP

packet can either reject it or insert a tag using its default VLAN ID. A given port can handle

traffic for more than one VLAN, but it can support only one default VLAN ID.

You can define VLAN groups stored in the VLAN membership table. The switch supports up

to 256 VLANs. VLAN 1 is created by default and is the default VLAN of which all ports are

members.

Forbidden VLANs The number of forbidden VLANs for the interface.

Dynamic VLANs The number of dynamically added VLANs for the interface.

Configure a MAC-based VLAN

The MAC-Based VLAN feature allows incoming untagged packets to be assigned to a VLAN

and thus classify traffic based on the source MAC address of the packet.

You define a MAC-to-VLAN mapping by configuring an entry in the MAC-to-VLAN table. An

entry is specified through a source MAC address and the desired VLAN ID. The

MAC-to-VLAN configurations are shared across all ports of the device (that is, a system-wide

table exists with MAC address–to–VLAN ID mappings).

When untagged or priority-tagged packets arrive at the switch and entries exist in the

MAC-to-VLAN table, the source MAC address of the packet is looked up. If an entry is found,

the corresponding VLAN ID is assigned to the packet. If the packet is already priority tagged

8-Port or 16-Port Gigabit Smart Managed Pro Switch Model GS418TPP, GS510TLP, and GS510TPP

Configure Switching User Manual148

it maintains this value. Otherwise, the priority is set to zero. The assigned VLAN ID is verified

against the VLAN table. If the VLAN is valid, ingress processing on the packet continues.

Otherwise, the packet is dropped. This implies that the user is allowed to configure a MAC

address mapping to a VLAN that was not created on the system.

Add a MAC-based VLAN

To add a MAC-based VLAN:

Configure protocol-based VLAN groups

You can use a protocol-based VLAN to define filtering criteria for untagged packets. By

default, if you do not configure any port-based (IEEE 802.1Q) or protocol-based VLANs,

untagged packets are assigned to VLAN 1. You can override this behavior by defining either

port-based VLANs or protocol-based VLANs, or both. Tagged packets are always handled

according to the IEEE 802.1Q standard and are not included in protocol-based VLANs.

If you assign a port to a protocol-based VLAN for a specific protocol, untagged frames

received on that port for that protocol are assigned the protocol-based VLAN ID. Untagged

frames received on the port for other protocols are assigned the port VLAN ID, either the

default PVID (1) or a PVID you specifically assigned to the port using the Port VLAN

Configuration page.

You define a protocol-based VLAN by creating a group. Each group forms a one-to-one

relationship with a VLAN ID, can include one to three protocol definitions, and can include

multiple ports. When you create a group, you specify a name and a group ID is assigned

automatically.

To configure a protocol-based VLAN group:

1. Connect your computer to the same network as the switch.

You can use a WiFi or wired connection to connect your computer to the network, or

Configure GARP switch settings

The Generic Attribute Registration Protocol (GARP) is used to exchange information

between GARP participants to register and deregister attribute values within a bridged LAN.

When a GARP participant declares or withdraws a given attribute, the attribute value is

recorded with the applicant state machine for that attribute, for the port from which the

declaration or withdrawal was made.

•Registration occurs only on ports that receive the GARP PDU containing a declaration or

withdrawal.

•Deregistration occurs only if all GARP participants connected to the same LAN segment

as the port withdraw the declaration.

GARP is part of the IEEE 802.1p extension to its 802.1D (spanning tree) specification. It

includes the following:

• GARP Information Declaration (GID). The part of GARP that generates data.

•GARP Information Propagation (GIP). The part of GARP that distributes data.

Configure Auto-VoIP

Voice over Internet Protocol (VoIP) enables telephone calls over a data network. Because

voice traffic is typically more time-sensitive than data traffic, the Auto-VoIP feature helps

provide a classification mechanism for voice packets so that they can be prioritized above

data packets in order to provide better Quality of Service (QoS). With the Auto-VoIP feature,

voice prioritization is provided based on call-control protocols (SIP, SCCP, H.323) or OUI bits.

Configure Auto-VoIP protocol-based settings

To prioritize time-sensitive voice traffic over data traffic, protocol-based Auto-VoIP checks for

packets carrying the following VoIP protocols:

•Session Initiation Protocol (SIP)

•H.323

•Signalling Connection Control Part (SCCP)

VoIP frames that are received on ports that for which the Auto-VoIP feature is enabled are

Configure Spanning Tree Protocol

The Spanning Tree Protocol (STP) provides a tree topology for any arrangement of network

devices. STP also provides one path between end stations on a network, eliminating loops.

STP (also referred to as “classic” STP) provides a single path between end stations, avoiding

and eliminating loops. For information about configuring the global STP settings for the

switch, see Configure the STP settings and view the STP status on page 164.

The switch support the following spanning tree versions:

• CST. Common STP. For information on configuring CST, see Configure the CST settings

on page 166 and Configure the CST port settings on page 167.

• MSTP. Multiple Spanning Tree Protocol (MSTP, also referred to as MST) supports

multiple instances of spanning tree to efficiently channel VLAN traffic over different

interfaces. For information on configuring MSTP, see Manage the MST settings on

page 172 and Configure and view the port settings for an MST instance on page 175.

• RSTP. Rapid STP. Each instance of the spanning tree behaves in the manner specified in

IEEE 802.1w, Rapid Spanning Tree (RSTP), with slight modifications in the working but

not the end effect (chief among the effects is the rapid transitioning of the port to the

forwarding state). For information on viewing the RSTP state, see View Rapid STP

Information on page 171.

The difference between the RSTP and the traditional STP (IEEE 802.1D) is the ability to

configure and recognize full-duplex connectivity and ports that are connected to end

8-Port or 16-Port Gigabit Smart Managed Pro Switch Model GS418TPP, GS510TLP, and GS510TPP

Configure Switching User Manual164

stations, resulting in rapid transitioning of the port to the forwarding state and the

suppression of Topology Change Notification. These features are represented by the

pointtopoint and edgeport parameters. MSTP is compatible with both RSTP and STP. It

behaves in a way that is appropriate for STP and RSTP bridges. An MSTP bridge can be

configured to behave entirely as an RSTP bridge or an STP bridge.

Note: For two bridges to be in the same region, the force version must be

802.1s and their configuration names, digest keys, and revision levels

must match. For additional information about regions and their effect

on network topology, refer to the IEEE 802.1Q standard.

Manage IGMP snooping

Internet Group Management Protocol (IGMP) snooping is a feature that allows a switch to

forward multicast traffic intelligently on the switch. Multicast IP traffic is traf fic that is destined

to a host group. Host groups are identified by class D IP addresses, which range from

224.0.0.0 to 239.255.255.255. Based on the IGMP query and report messages, the switch

forwards traffic only to the ports that request the multicast traffic. This prevents the switch

from broadcasting the traffic to all ports and possibly affecting network performance.

A traditional Ethernet network can be separated into different network segments to prevent

placing too many devices onto the same shared media. Bridges and switches connect these

segments. When a packet with a broadcast or multicast destination address is received, the

switch forwards a copy to each of the remaining network segments in accordance with the

IEEE MAC Bridge standard. Eventually, the packet is made accessible to all nodes

connected to the network.

This approach works well for broadcast packets that are intended to be seen or processed by

all connected nodes. In the case of multicast packets, however, this approach could lead to

less efficient use of network bandwidth, particularly when the packet is intended for only a

small number of nodes. Packets are flooded into network segments where no node is

receptive to the packet. While nodes rarely incur any processing overhead to filter packets

addressed to unrequested group addresses, they cannot transmit new packets onto the

shared media for the period of time that the multicast packet is flooded. The problem of

wasting bandwidth is even worse when the LAN segment is not shared, for example in

full-duplex links.

Allowing switches to snoop IGMP packets is a creative effort to solve this problem. The

switch uses the information in the IGMP packets as they are being forwarded throughout the

network to determine which segments receive packets directed to the group address.

You can configure the settings for IGMP snooping, which is used to build forwarding lists for

IGMP snooping querier overview

IGMP snooping requires that one central switch or router periodically query all end-devices

on the network to announce their multicast memberships. This central device is the IGMP

querier. The IGMP query responses, known as IGMP reports, keep the switch updated with

the current multicast group membership on a port-by-port basis. If the switch does not

receive updated membership information in a timely fashion, it stops forwarding multicasts to

the port where the end device is located.

You can configure and display information about IGMP snooping queriers on the network

and, separately, on VLANs.

Manage MLD snooping

In IPv6 networks, Multicast Listener Discovery (MLD) snooping performs a similar function as

IGMP does in IPv4 networks. With MLD snooping, IPv6 multicast data is selectively

forwarded to ports that are configured to receive the data, instead of being flooded to all ports

in a VLAN. The ports are determined by snooping IPv6 multicast control packets.

A multicast listener is a device that is configured to receive IPv6 multicast packets. MLD is

used by IPv6 multicast routers to discover the presence of multicast listeners on its

directly-attached links and to discover which multicast packets are of interest to neighboring

devices.

The MLD protocol is derived from IGMP. MLD version 1 (MLDv1) is equivalent to IGMPv2,

and MLD version 2 (MLDv2) is equivalent to IGMPv3. MLD is a subprotocol of Internet

Control Message Protocol version 6 (ICMPv6), and MLD messages are a subset of ICMPv6

messages, identified in IPv6 packets by a preceding Next Header value of 58.

Configure multicast VLAN registration

IGMP snooping helps limit multicast traffic when member ports are in the same VLAN.

However, when ports belong to different VLANs, a copy of the multicast stream is sent to

each VLAN with member ports in the multicast group. Multicast VLAN registration (MVR)

eliminates the need to duplicate the multicast traffic when multicast group member ports

belong to different VLANs.

MVR uses a dedicated multicast VLAN to forward multicast traffic over the L2 network. Only

one multicast source VLAN (MVLAN can be configured per switch, and it is used only for

certain multicast traffic, such as traffic from an IPTV application, to avoid duplication of

multicast streams for clients in different VLANs. Clients can dynamically join or leave the

multicast VLAN without interfering with their membership in other VLANs.

MVR, like IGMP snooping, allows a Layer 2 switch to listen to IGMP messages to learn about

multicast group membership.

You can configure basic, advanced, group, interface, or group membership settings.

Configure Layer 2 loop protection

Loops inside a network are costly because they consume resources and reduce the

performance of the network. Detecting loops manually can be cumbersome.

The switch can automatically identify loops in the network. You can enable loop protection

per port or globally.

If loop protection is enabled, the switch sends predefined PDU packets to a Layer 2 multicast

destination address (09:00:09:09:13:A6) on all ports for which the feature is enabled. You

can selectively disable PDU packet transmission for loop protection on specific ports even

while port loop protection is enabled. If the switch receives a packet with the previously

mentioned multicast destination address, the source MAC address in the packet is compared

with the MAC address of the switch. If the MAC address does not match, the packet is

forwarded to all ports that are members of the same VLAN, just like any other multicast

packet. The packet is not forwarded to the port from which it was received.

If the source MAC address matches the MAC address of the switch, the switch can perform

one of the following actions, depending on how you configure the action:

•The port is shut down.

•A log message is generated. (If a syslog server is configured, the log message can be

sent to the syslog server.)

•The port is shut down and a log message is generated.

If loop protection is disabled, the multicast packet is silently dropped.

Loop protection is not intended for ports that serve as uplinks between spanning tree–aware

switches. It is intended for unmanaged switches that drop spanning tree BPDUs. Loop

protection detects physical and logical loops between Ethernet ports on a device. You must

enable loop protection globally before you can enable and configure it at the interface level.

Loop protection is supported on physical interfaces and static LAG interfaces, but not on

dynamic LAG interfaces.

Routing concepts

The switch supports IP routing. When a packet enters the switch, the switch checks the

destination MAC address to determine if it matches any of the configured routing interfaces. If

it does, the switch searches the host table for a matching destination IP address. If a

matching entry is found, the packet is routed to the host. If no matching entry is found, the

switch performs a longest prefix match on the destination IP address. If a matching entry is

found, the packet is routed to the next hop. If no matching entry is found, the packet is routed

to the next hop that is specified in the default route. If no default route exists, the packet is are

dropped.

The routing table can include static entries that you added manually. The host table can

include static entries that were manually added and entries that were dynamically added

through ARP.

Configure the routing mode

including bad checksums, version number mismatch, other format errors,

time-to-live exceeded, errors discovered in processing their IP options, and

so on.

IpInAddrErrors The number of input datagrams discarded because the IP address in their

IP header’s destination field was not a valid address to be received at this

entity. This count includes invalid addresses (for example, 0.0.0.0) and

addresses of unsupported classes (Class E). For entities that are not IP

gateways and therefore do not forward datagrams, this counter includes

datagrams discarded because the destination address was not a local

address.

IpForwDatagrams The number of input datagrams for which this entity was not their final IP

destination, as a result of which an attempt was made to find a route to

forward them to that final destination. In entities that do not act as IP

gateways, this counter includes only those packets that were source-routed

through this entity, and the source-route option processing was successful.

IpInUnknownProtos The number of locally addressed datagrams received successfully but

discarded because of an unknown or unsupported protocol.

IpInDiscards The number of input IP datagrams for which no problems were encountered

to prevent their continued processing, but that were discarded (for lack of

buffer space). This counter does not include any datagrams discarded while

awaiting re-assembly.

IpInDelivers The total number of input datagrams successfully delivered to IP user

protocols (including ICMP).

IpOutRequests The total number of IP datagrams that local IP user protocols (including

ICMP) supplied to IP in requests for transmission. This counter does not

include any datagrams counted in ipForwDatagrams.

IpOutDiscards The number of output IP datagrams for which no problem was encountered

to prevent their transmission to their destination, but that were discarded for

reasons such as lack of buffer space. This counter would include

datagrams counted in ipForwDatagrams if any such packets met this

(discretionary) discard criterion.

IpOutNoRoutes The number of IP datagrams discarded because no route could be found to

transmit them to their destination. This counter includes any packets

counted in ipForwDatagrams that meet this no-route criterion. This includes

any datagrams that a host cannot route because all of its default gateways

are down.

IpReasmTimeout The maximum number of seconds for which received fragments are held

while they are awaiting reassembly at this entity.

IpReasmReqds The number of IP fragments received that were reassembled at this entity.

IpReasmOKs The number of IP datagrams successfully reassembled.

IpReasmFails The number of failures detected by the IP reassembly algorithm (for

whatever reason: timed out, errors, and so on). This is not necessarily a

count of discarded IP fragments since some algorithms can lose track of the

number of fragments by combining them as they are received.

IpFragOKs The number of IP datagrams that were fragmented at this entity.

IpFragFails The number of IP datagrams that were discarded because they needed to

be fragmented at this entity but could not be, for reasons such as their Don't

Fragment flag was set.

IpFragCreates The number of IP datagram fragments that were generated as a result of

fragmentation at this entity.

IcmpOutMsgs The total number of ICMP messages that this entity attempted to send. This

counter includes all those counted by icmpOutErrors.

IcmpOutErrors The number of ICMP messages that this entity did not send due to

problems discovered within ICMP such as a lack of buffers. This value does

not include errors discovered outside the ICMP layer such as the inability of

IP to route the resultant datagram. In some implementations there might be

no types of error that contribute to this counter's value.

IcmpOutDestUnreachs The number of ICMP destination unreachable messages sent.

IcmpOutTimeExcds The number of ICMP time exceeded messages sent.

IcmpOutParmProbs The number of ICMP parameter problem messages sent.

IcmpOutSrcQuenchs The number of ICMP source quench messages sent.

IcmpOutRedirects The number of ICMP redirect messages sent. For a host, this is always

zero, since hosts do not send redirects.

IcmpOutEchos The number of ICMP echo (request) messages sent.

IcmpOutEchoReps The number of ICMP echo reply messages sent.

Field Description

Total Datagrams Received The total number of input datagrams received by the interface, including

those received in error.

Received Datagrams Locally

Delivered The total number of datagrams successfully delivered to IPv6

user-protocols (including ICMP). This counter is incremented at the

interface to which these datagrams were addressed, which might not be

the input interface for some of the datagrams.

8-Port or 16-Port Gigabit Smart Managed Pro Switch Model GS418TPP, GS510TLP, and GS510TPP

Configure Routing User Manual233

Received Datagrams Discarded

Due To Header Errors The number of input datagrams discarded due to errors in their IPv6

headers, including version number mismatch, other format errors, hop

count exceeded, errors discovered in processing their IPv6 options, and

so on.

Received Datagrams Discarded

Due To MTU The number of input datagrams that could not be forwarded because their

size exceeded the link MTU of outgoing interface.

Received Datagrams Discarded

Due To No Route The number of input datagrams discarded because no route could be

found to transmit them to their destination.

Received Datagrams With Unknown

Protocol The number of locally addressed datagrams received successfully but

discarded because of an unknown or unsupported protocol. This counter

is incremented at the interface to which these datagrams were addressed,

which might not be the input interface for some of the datagrams.

Received Datagrams Discarded

Due To Invalid Address The number of input datagrams discarded because the IPv6 address in

their IPv6 header's destination field was not a valid address to be received

at this entity. This count includes invalid addresses (for example, ::0) and

unsupported addresses (such as addresses with unallocated prefixes).

For entities that are not IPv6 routers and therefore do not forward

datagrams, this counter includes datagrams discarded because the

destination address was not a local address.

Received Datagrams Discarded Dut

To Truncated Data The number of input datagrams discarded because datagram frame didn't

carry enough data.

Received Datagrams Discarded

Other The number of input IPv6 datagrams for which no problems were

encountered to prevent their continued processing, but that were

discarded for reasons such as lack of buffer space. This counter does not

include any datagrams discarded while awaiting reassembly.

Received Datagrams Reassembly

Required The number of IPv6 fragments received that needed to be reassembled at

this interface. This counter is incremented at the interface to which these

fragments were addressed, which might not be the input interface for

some of the fragments.

Datagrams Successfully

Reassembled The number of IPv6 datagrams successfully reassembled. This counter is

incremented at the interface to which these datagrams were addressed,

which might not be necessarily the input interface for some of the

fragments.

Datagrams Failed To Reassemble The number of failures detected by the IPv6 reassembly algorithm (for

whatever reason: timed out, errors, and so on). This is not necessarily a

count of discarded IPv6 fragments since some algorithms (notably the

algorithm in RFC 815) can lose track of the number of fragments by

combining them as they are received. This counter is incremented at the

interface to which these fragments were addressed, which might not be

the input interface for some of the fragments.

Datagrams Forwarded The number of output datagrams that this entity received and forwarded to

their final destinations. In entities that do not act as IPv6 routers, this

counter includes only those packets that were source-routed through this

entity, and the source-route processing was successful. For a successfully

forwarded datagram the counter of the outgoing interface is incremented.

Configure the IPv6 route preferences

You can configure the default preference for each protocol. These values are arbitrary values

in the range of 1 to 255 and are independent of route metrics. Most routing protocols use a

route metric to determine the shortest path known to the protocol, independent of any other

protocol. The switch selects the route with the lowest preference value as the best route to a

destination. When multiple routes to a destination exist, the preference values are used to

determine the preferred route. If these preference values routes are equal, the route with the

best route metric is chosen. To avoid problems with mismatched metrics, you must configure

different preference values for each of the protocols.

Configure VLAN routing

You can configure the switch with some ports supporting VLANs and some ports supporting

routing. You can also configure the switch to allow traffic on a VLAN to be treated as if the

VLAN were a router port.

When a port is enabled for bridging (the default setting) rather than routing, all normal bridge

processing is performed for an inbound packet, which is then associated with a VLAN. Its

MAC destination address (MAC DA) and VLAN ID are used to search the MAC address

table. If routing is enabled for the VLAN, and the MAC DA of an inbound unicast packet is

that of the internal bridge-router interface, the packet is routed. An inbound multicast packet

is forwarded to all ports in the VLAN. If a routed VLAN receives the multicast packet, the

packet is also forwarded on the internal bridge-router interface.

Because you can configure a port to belong to more than one VLAN, VLAN routing might be

enabled for all of the VLANs on the port, or for a subset. You can use VLAN routing to allow

more than one physical port to reside on the same subnet. You can also use VLAN routing if

a VLAN spans multiple physical networks, or if you require additional segmentation or

security. A port can either be a VLAN port or a router port, but not both. However, a VLAN

port can be part of a VLAN that is itself a router port.

Configure Address Resolution Protocol

The Address Resolution Protocol (ARP) associates a Layer 2 MAC address with a Layer 3

IPv4 address. ARP is a part of the Internet Protocol (IP) and is used to translate an IP

address to a media (MAC) address, defined by a LAN such as an Ethernet LAN.

The switch supports both dynamic and manual ARP configurations. With a manual ARP

configuration, you can statically add entries to the ARP table.

A device that sends an IP packet must learn the MAC address of the IP destination, or, if the

destination is not on the same subnet, of the next hop router. The device broadcasts an ARP

request packet, to which the intended recipient responds with a unicast ARP reply that

contains its MAC address. The device then uses the MAC address in the destination address

field of the Layer 2 header that is prepended to the IP packet and sent to the recipient. Each

device in a network maintains its ARP cache locally.

The switch learns ARP cache entries by examining the source information in the ARP packet

payload fields, regardless of whether it is an ARP request or a response. In that way, when

8-Port or 16-Port Gigabit Smart Managed Pro Switch Model GS418TPP, GS510TLP, and GS510TPP

Configure Routing User Manual250

an ARP request is broadcast to all stations on a LAN segment or VLAN, each recipient can

store the sender’s IP and MAC address in its ARP cache. Normally, only the requestor

receives an ARP response (a unicast message) and stores the sender’s information in its

ARP cache. The most recent information always replaces existing content in the ARP cache.

A device can be moved in a network, which means that the device’s IP address that was

associated with one MAC address is now associated with another MAC address. A device

can also disappear from the network altogether (for example, it was reconfigured,

disconnected, or powered off). These situations cause stale information in the ARP cache.

Therefore, entries are updated or periodically refreshed to determine if an address still exists.

If an entry was identified as a sender of an ARP packet, the entry can be removed from the

ARP cache. You can configure an age-out interval that determines how long an entry that is

not updated remains in the ARP cache.

View the ARP cache

You can view ARP entries in the ARP cache. The ARP cache is a table that lists the remote

connections that were recently detected by the switch.

This chapter covers the following topics:

•Quality of Service concepts

•Manage the Class of Service

•Manage Differentiated Services

8-Port or 16-Port Gigabit Smart Managed Pro Switch Model GS418TPP, GS510TLP, and GS510TPP

Configure Quality of Service User Manual257

Quality of Service concepts

In a switch, each physical port consists of one or more queues for transmitting packets on the

attached network. Multiple queues per port are often provided to give preference to certain

packets over others based on user-defined criteria. When a packet is queued for

transmission in a port, the rate at which it is serviced depends on how the queue is

configured and possibly the amount of traffic present in the other queues of the port. If a

delay is necessary, packets are held in the queue until the scheduler authorizes the queue for

transmission. As queues become full, packets can no longer be held for transmission and are

dropped by the switch.

Quality of Service (QoS) is a means of providing consistent, predictable data delivery by

distinguishing packets with strict timing requirements from those that are more tolerant of

delay. Packets with strict timing requirements are given special treatment in a QoS-capable

network. With this in mind, all elements of the network must be QoS capable. The presence

of at least one node that is not QoS capable creates a deficiency in the network path, and the

performance of the entire packet flow is compromised.

Manage the Class of Service

The Class of Service (CoS) queueing feature lets you directly configure certain aspects of

switch queueing. This provides the desired QoS behavior for dif ferent types of network traf fic

when the complexities of DiffServ are not required. The priority of a packet arriving at an

interface can be used to steer the packet to the appropriate outbound CoS queue through a

mapping table. CoS queue characteristics that affect queue mapping, such as minimum

guaranteed bandwidth or transmission rate shaping, are user configurable at the queue (or

port) level.

Eight queues per port are supported.

CoS configuration concepts

You can set the Class of Service trust mode for an interface. Each port in the switch can be

configured to trust one of the packet fields (802.1p or IP DSCP), or to not trust any packet’s

priority designation (untrusted mode). If the port is set to a trusted mode, it uses a mapping

table appropriate for the trusted field being used. This mapping table indicates the CoS

queue to which the packet must be forwarded on the appropriate egress port. Of course, the

trusted field must exist in the packet for the mapping table to be of any use. If this is not the

case, default actions are performed. These actions involve directing the packet to a specific

CoS level configured for the ingress port as a whole, based on the existing port default

priority as mapped to a traffic class by the current 802.1p mapping table.

Alternatively, when a port is configured as untrusted, it does not trust any incoming packet

priority designation and uses the port default priority value instead. All packets arriving at the

ingress of an untrusted port are directed to a specific CoS queue on the appropriate egress

8-Port or 16-Port Gigabit Smart Managed Pro Switch Model GS418TPP, GS510TLP, and GS510TPP

Configure Quality of Service User Manual258

ports, in accordance with the configured default priority of the ingress port. This process is

also used for cases where a trusted port mapping cannot be honored, such as when a non-IP

packet arrives at a port configured to trust the IP DSCP value.

• 802.1p. The eight priority tags that are specified in IEEE 802.1p are p0 to p7. The

QoS setting lets you map each of the eight priority levels to one of seven internal

hardware priority queues. The default value is 802.1p.

• DSCP. The six most significant bits of the DiffServ field are called the Differentiated

Services Code Point (DSCP) bits.

9. In the Interface Shaping Rate field, specify the maximum bandwidth allowed.

This is typically used to shape the outbound transmission rate in increments of 64 kbps in

the range 16 to 16384 kbps.This value is controlled independently of any per-queue

maximum bandwidth configuration. It is effectively a second-level shaping mechanism.

The default value is 0. The value 0 means that the maximum is unlimited.

The expected shaping at egress interface is calculated as follows:

frameSize × shaping/(frameSize + IFG), where IFG (Inter frame gap) is 20 bytes,

frameSize is configured frame size, and shaping is configured traffic shaping.

For example, when 64 bytes frame size and 64 kbps shaping are configured, expected

shaping is approximately 48 kbps.

Configure the CoS queue settings for an interface

You can define what a particular queue does by configuring switch egress queues. You can

control how much bandwidth is used by the queue, the queue depth during times of

congestion, and the scheduling of packet transmission from all queues on a port. Each port

contains its own CoS queue-related configuration.

For information about configuring CoS queue settings globally, see Configure the global

CoS settings on page 258.

To configure CoS queue settings for an interface:

1. Connect your computer to the same network as the switch.

You can use a WiFi or wired connection to connect your computer to the network, or

connect directly to a switch that is off-network using an Ethernet cable.

2. Launch a web browser.

queue.

Setting this value higher than its corresponding maximum bandwidth automatically

increases the maximum to the same value. The default value is 0. The valid range is 0 to

100 in increments of 1. The value 0 means no guaranteed minimum. The sum of the

individual minimum bandwidth values for all queues for the interface cannot exceed the

defined maximum (100).

10. From the Scheduler Type menu, select one of the following options:

•Strict. The interface services traffic with the highest priority on a queue first.

•Weighted. The interface uses weighted round robin to associate a weight to each

queue. This is the default setting.

The Queue Management Type field displays the queue depth management technique

that is used for queues on the interface. By default, this method is Taildrop, irrespective of

your selection from the Scheduler Type menu.

Map 802.1p priorities to queues

You can view or change which internal traffic classes are mapped to the 802.1p priority class

values in Ethernet frames that the device receives. The priority-to-traffic class mappings can

be applied globally or per interface. The mapping allows the switch to group various traffic

types (for example, data or voice) based on their latency requirements and give preference to

time-sensitive traffic.

To map 802.1p priorities to queues:

1. Connect your computer to the same network as the switch.

You can use a WiFi or wired connection to connect your computer to the network, or

connect directly to a switch that is off-network using an Ethernet cable.

7. In the 802.1p to Queue Mapping table, map each of the eight 802.1p priorities to a queue

(internal traffic class).

The 802.1p Priority row contains traffic class selectors for each of the eight 802.1p

priorities to be mapped. The priority goes from low (0) to high (7). For example, traf fic with

a priority of 0 is for most data traffic and is sent using best effort. Traffic with a higher

priority, such as 7, might be time-sensitive traffic, such as voice or video.

The values in the menu under each priority represent the traffic class. The traffic class is

the hardware queue for a port. Higher traffic class values indicate a higher queue

position. Before traffic in a lower queue is sent, it must wait for traffic in higher queues to

be sent.

class must be mapped to the DSCP value.

The traffic class is the hardware queue for a port. Higher traffic class values indicate a

higher queue position. Before traffic in a lower queue is sent, it must wait for traffic in

higher queues to be sent.

The allowed Per Hop Behavior (PHBs) values, apart from other DSCP experimental

values, are as follows:

•Class Selector (CS) PHB. These values are based on IP precedence.

• Assured Forwarding (AF) PHB. These values define four main levels to sort and

manipulate some flows within the network.

• Expedited Forwarding (EF) PHB. These values are used to prioritize traffic for

real-time applications. In many situations, if the network exceeded traffic and you

need some bandwidth guaranteed for an application, the EF traffic must receive this

rate independently of the intensity of any other traffic attempting to transit the node.

Manage Differentiated Services

The QoS feature contains Differentiated Services (DiffServ) support that allows traffic to be

classified into streams and given certain QoS treatment in accordance with defined per-hop

behaviors.

Standard IP-based networks are designed to provide best effort data delivery service. Best

effort service implies that the network delivers the data in a timely fashion, although there is

no guarantee. During times of congestion, packets might be delayed, sent sporadically, or

dropped. For typical Internet applications, such as email and file transfer , a slight degradation

in service is acceptable and in many cases unnoticeable. Conversely, any degradation of

service can negatively affect applications with strict timing requirements, such as voice or

multimedia.

Defining DiffServ

To use DiffServ for QoS, you must first define the following categories and their criteria:

1. Class. Create classes and define class criteria.

2. Policy. Create policies, associate classes with policies, and define policy statements.

3. Service. Add a policy to an inbound interface.

Packets are classified and processed based on defined criteria. The classification criteria are

defined by a class. The processing is defined by a policy’ s attributes. Policy attributes can be

defined on a per-class instance basis, and it is these attributes that are applied when a match

occurs. A policy can contain multiples classes. When the policy is active, the actions taken

depend on which class matches the packet.

Note the following about the DiffServ process:

•Packets are filtered and processed based on defined criteria. The filtering criteria is

defined by a class. The processing is defined by a policy's attributes. Policy attributes can

be defined on a per-class instance basis, and it is these attributes that are applied when a

match occurs.

•The configuration process begins with defining one or more match criteria for a class.

Then one or more classes are added to a policy. Policies are then added to interfaces.

Packet processing begins by testing the match criteria for a packet. The All class type option

specifies that each match criteria within a class must evaluate to true for a packet to match

that class. The Any class type option specifies that at least one match criteria must evaluate

to true for a packet to match that class. Classes are tested in the order in which they were

added to the policy. A policy is applied to a packet when a class match within that policy is

found.

Configure DiffServ IPv6 class settings

The switch supports QoS ACL and DiffServ functionality for IPv6 by providing support for

IPv6 packet classification. An IPv6 ACL serves the same purpose as an IPv4 ACL.

An Ethernet IPv6 packet is distinguished from an IPv4 packet by its unique Ethertype value,

so all IPv6 classifiers include the Ethertype field, even though you cannot configure its value

on the switch.

The destination and source IPv6 addresses use a prefix length value instead of an individual

mask to qualify them as a subnet addresses or a host addresses. Packets that match an IPv6

classifier can be marked with the IP DSCP field in the traffic class octet.

You can also assign an IPv6 ACL with a DiffServ assignment to LAG interfaces.

Manage the RADIUS settings

RADIUS servers provide additional security for networks. The RADIUS server maintains a

user database, which contains per-user authentication information. The switch passes

information to the configured RADIUS server, which can authenticate a user name and

password before authorizing use of the network. RADIUS servers provide a centralized

authentication method for the following:

•Web access

•Access control port (802.1X)

Configure the global RADIUS server settings

You can add information about one or more RADIUS servers on the network.

If you configure multiple RADIUS servers, consider the maximum delay time when you

specify the maximum number of retransmissions (that is, the value that you enter in the Max

Number of Retransmits field) and the time-out period (that is, the value that you enter in the

Timeout Duration field) for RADIUS:

For one RADIUS server, a retransmission does not occur until the configured time-out

period expires without a response from the RADIUS server. In addition. the maximum

number of retransmissions for one RADIUS server must pass before the switch attempts

the next RADIUS server.

Therefore, the maximum delay in receiving a RADIUS response on the switch equals the

maximum number of retransmissions multiplied by the time-out period multiplied by the

number of configured RADIUS servers. If the RADIUS request was generated by a user

response.

To configure the global RADIUS server settings:

1. Connect your computer to the same network as the switch.

You can use a WiFi or wired connection to connect your computer to the network, or

connect directly to a switch that is off-network using an Ethernet cable.

2. Launch a web browser.

The Current Server IP Address field is blank if no servers are configured (see Configure

three RADIUS servers. If more than one RADIUS server is configured, the current server

is the server configured as the primary server. If no servers are configured as the primary

server, the current server is the most recently added RADIUS server.

CAUTION:

The maximum delay in receiving a RADIUS response on the switch equals

the maximum number of retransmissions multiplied by the time-out period

multiplied by the number of configured RADIUS servers. If the RADIUS

request was generated by a user login attempt, all user interfaces are

blocked until the switch receives a RADIUS response.

6. In the Max Number of Retransmits field, specify the maximum number of times a request

packet is retransmitted to the RADIUS server.

The range is from 1 to 15. The default value is 4.

7. In the Timeout Duration field, specify the time-out value, in seconds, for request

retransmissions.

The range is from 1 to 30. The default value is 5.

Configure port authentication

With port-based authentication, when 802.1X is enabled globally and on the port, successful

authentication of any one supplicant attached to the port results in all users being able to use

the port without restrictions. At any given time, only one supplicant is allowed to attempt

authentication on a port in this mode. Ports in this mode are under bidirectional control. This

is the default authentication mode.

An 802.1X network includes three components:

• Authenticators. The port that is authenticated before system access is permitted.

•Supplicants. The host connected to the authenticated port requesting access to the

system services.

•Authentication Server. The external server, for example, the RADIUS server that

performs the authentication on behalf of the authenticator , and indicates whether the user

is authorized to access system services.

5. Select Security > Port Authentication > Basic > 802.1X Configuration.

6. Select the Port Based Authentication State Enable radio button.

This enables the 802.1X administrative mode on the switch. The default value is Disable.

Note: If 802.1X is enabled, authentication is performed by a RADIUS server.

This means that the primary authentication method must be RADIUS.

To set the method, select Security > Management Security >

Authentication List and select RADIUS as method 1 for defaultList.

For more information, see Configure authentication lists on

page 302.

When port-based authentication is globally disabled, the switch does not check for

802.1X authentication before allowing traffic on any ports, even if the ports are configured

to allow only authenticated users.

7. Select the VLAN Assignment Mode Enable radio button.

The default value is Disable.

When enabled, this feature allows a port to be placed into a particular VLAN based on the

result of the authentication or type of 802.1X authentication a client uses when it

8-Port or 16-Port Gigabit Smart Managed Pro Switch Model GS418TPP, GS510TLP, and GS510TPP

Manage Device Security User Manual322

accesses the device. The authentication server can provide information to the device

about which VLAN to assign the supplicant.

8. Select the Dynamic VLAN Creation Mode Enable radio button.

The default value is Disable.

If RADIUS-assigned VLANs are enabled, the RADIUS server is expected to include the

VLAN ID in the 802.1X tunnel attributes of its response message to the device. If dynamic

VLAN creation is enabled on the device and the RADIUS-assigned VLAN does not exist,

then the assigned VLAN is dynamically created. This implies that the client can connect

from any port and can get assigned to the appropriate VLAN. This feature gives flexibility

for clients to move around the network without much additional configuration required.

9. Select the EAPOL Flood Mode Enable radio button.

The default value is Disable. Extensible Authentication Protocol (EAP) over LAN (EAPoL)

flood support is enabled on the switch.

8. Specify the following settings:

•Port Control. Defines the port authorization state. The control mode is set only if the

link status of the port is link up. Select one of the following options:

- Auto. The switch automatically detects the mode of the interface.

- Authorized. The switch places the interface into an authorized state without

being authenticated. The interface sends and receives normal traf fic without client

port-based authentication.

- Unauthorized. The switch denies the selected interface system access by

moving the interface into unauthorized state. The switch cannot provide

authentication services to the client through the interface.

-MAC based. This mode allows multiple supplicants connected to the same port to

each authenticate individually. Each host connected to the port must authenticate

separately in order to gain access to the network. The hosts are distinguished by

their MAC addresses.

• Guest VLAN ID. Specify the VLAN ID for the guest VLAN. The valid range is 0–4093.

The default value is 0. Enter 0 to reset the guest VLAN ID on the interface. The guest

VLAN allows the port to provide a distinguished service to unauthenticated users,

after three authentication failures. This feature provides a mechanism to allow users

access to hosts on the guest VLAN.

• Guest VLAN Period. Specify the number of seconds that the selected port remains

in the quiet state following a failed authentication exchange. The guest VLAN time-out

must be a value in the range of 1–300. The default value is 90.

•Unauthenticated VLAN ID. Specify the VLAN ID of the unauthenticated VLAN for the

selected port. The valid range is 0–3965. The default value is 0. Hosts that fail the

authentication might be denied access to the network or placed on a VLAN created

8-Port or 16-Port Gigabit Smart Managed Pro Switch Model GS418TPP, GS510TLP, and GS510TPP

Manage Device Security User Manual324

for unauthenticated clients. This VLAN might be configured with limited network

access.

• Periodic Reauthentication. Select Enable to allow periodic reauthentication of the

supplicant for the specified port.

• Reauthentication Period. Specify the time, in seconds, after which reauthentication

of the supplicant occurs. The reauthentication period must be a value in the range of

1–65535. The default value is 3600. If this field is disabled, connected clients are not

forced to reauthenticate periodically.

• Quiet Period. Specify the number of seconds that the port remains in the quiet state

following a failed authentication exchange. While in the quite state, the port does not

attempt to acquire a supplicant.

• Resending EAP. Specify the EAP retransmit period for the selected port. The

transmit period is the value, in seconds, after which an EAPoL EAP Request/Identify

frame is resent to the supplicant.

• Max EAP Requests. Specify the maximum number of EAP requests for the selected

port. The value is the maximum number of times an EAPoL EAP Request/Identity

message is retransmitted before the supplicant times out.

•Supplicant Timeout. Specify the supplicant time-out for the selected port. The

supplicant time-out is the value, in seconds, after which the supplicant times out.

•Server Timeout. Specify the time that elapses before the switch resends a request to

the authentication server.

Configure storm control settings

A broadcast storm is the result of an excessive number of broadcast messages

simultaneously transmitted across a network by a single port. Forwarded message

responses can overload network resources, cause the network to time out, or do both.

The switch measures the incoming packet rate per port for broadcast, multicast, unknown,

and unicast packets and discards packets if the rate exceeds the defined value. You enable

storm control per interface, by defining the packet type and the rate at which the packets are

transmitted.

Field Description

Port The physical interface.

Last Violation MAC The source MAC address of the last packet that was discarded at a locked port.

VLAN ID The VLAN ID corresponding to the last MAC address violation.

Configure a port security interface

A MAC address can be defined as allowable by one of two methods: dynamically or statically.

Both methods are used concurrently when a port is locked.

Dynamic locking implements a first arrival mechanism for port security. You specify how

many addresses can be learned on the locked port. If the limit was not reached, then a

packet with an unknown source MAC address is learned and forwarded normally. When the

limit is reached, no more addresses are learned on the port. Any packets with source MAC

addresses that were not already learned are discarded. You can effectively disable dynamic

locking by setting the number of allowable dynamic entries to zero.

Static locking allows you to specify a list of MAC addresses that are allowed on a port. The

behavior of packets is the same as for dynamic locking: only packets with an allowable

source MAC address can be forwarded.

To configure a port security interface:

1. Connect your computer to the same network as the switch.

You can use a WiFi or wired connection to connect your computer to the network, or

Configure access control lists

Access control lists (ACLs) ensure that only authorized users can access specific resources

while blocking off any unwarranted attempts to reach network resources. ACLs are used to

provide traffic flow control, restrict contents of routing updates, decide which types of traffic

are forwarded or blocked, and above all provide security for the network. The switch’s

software supports IPv4, IPv6, and MAC ACLs.

To configure an ACL:

1. Create an IPv4-based or IPv6-based or MAC-based ACL ID.

2. Create a rule and assign it to a unique ACL ID.

3. Define the rules, which can identify protocols, source, and destination IP and MAC

addresses, and other packet-matching criteria.

4. Use the ID number to assign the ACL to a port or to a LAG.

To view ACL configuration examples, see Access control lists (ACLs) on page 451.

Use the ACL Wizard to create a simple ACL

The ACL Wizard helps you create a simple ACL and apply it to the selected ports easily and

quickly. First, select an ACL type to use when you create an ACL. Then add an ACL rule to

this ACL and apply this ACL on the selected ports.

Note: The steps in the following procedure describe how you can create an

ACL based on the destination MAC address. If you select a different

type of ACL (or example, an ACL based on a source IPv4), the page

displays different information.

ACL Wizard example

In the following figure, the ACL rule is configured to check for packet matches on ports 4, 5,

and 9 and on LAG 1. Only the Inbound option is valid. Packets that include a source address

in the 192.168.3.0/16 network are permitted to be forwarded by the interfaces. All other

packets are dropped because every ACL includes an implicit deny all rule as the last rule.

For information about the ACL Wizard, see Use the ACL Wizard to create a simple ACL on

page 347.

Configure a MAC ACL

A MAC ACL consists of a set of rules that are matched sequentially against a packet. When a

packet meets the match criteria of a rule, the specified rule action (Permit or Deny) is taken,

and the additional rules are not checked for a match. Rules for the MAC ACL are created

using the MAC ACL Rule Configuration page.

Multiple steps are involved in defining a MAC ACL and applying it to the switch:

1. Create the ACL ID.

2. Create a MAC rule.

3. Associate the MAC ACL with one or more interfaces.

You can view or delete MAC ACL configurations in the MAC Binding table (see View or

delete MAC ACL bindings in the MAC binding table on page 360.

Configure a basic or extended IPv4 ACL

An IPv4 ACL consists of a set of rules that are matched sequentially against a packet. When

a packet meets the match criteria of a rule, the specified rule action (Permit or Deny) is taken,

and the additional rules are not checked for a match. You must specify the interfaces to

which an IPv4 ACL applies, as well as whether it applies to inbound or outbound traffic.

Multiple steps are involved in defining an IPv4 ACL and applying it to the switch:

1. Add an IPv4 ACL ID (see Add an IPv4 ACL on page 362).

The differences between a basic IPv4 ACL and an extended IPv4 ACL are as follows:

• Numbered ACL from 1 to 99. Creates a basic IPv4 ACL, which allows you to permit

or deny traffic from a source IP address.

•Numbered ACL from 100 to 199. Creates an extended IPv4 ACL, which allows you

to permit or deny specific types of Layer 3 or Layer 4 traffic from a source IP address

8-Port or 16-Port Gigabit Smart Managed Pro Switch Model GS418TPP, GS510TLP, and GS510TPP

Manage Device Security User Manual362

to a destination IP address. This type of ACL provides more granularity and filtering

capabilities than the basic IP ACL.

• Named IP ACL. Create an extended IPv4 ACL with a name string that is up to 31

alphanumeric characters in length. The name must start with an alphabetic character.

2. Create an IPv4 rule (see Configure rules for a basic IPv4 ACL on page 364 or

Configure rules for an extended IPv4 ACL on page 368).

3. Associate the IPv4 ACL with one or more interfaces (see Configure IP ACL interface

bindings on page 385).

6. In the IP ACL ID field, specify the ACL ID or IP ACL name, which depends on the IP ACL

type. The IP ACL ID is an integer in the following range:

• 1–99. Creates a basic IP ACL, which allows you to permit or deny traffic from a

source IP address.

• 100–199. Creates an extended IP ACL, which allows you to permit or deny specific

types of Layer 3 or Layer 4 traffic from a source IP address to a destination IP

address. This type of ACL provides more granularity and filtering capabilities than the

standard IP ACL.

• IP ACL Name. Create an IPv4 ACL name string that is up to 31 alphanumeric

characters in length. The name must start with an alphabetic character.

Each configured ACL displays the following information:

• Rules. The number of rules currently configured for the IP ACL.

•Type. Identifies the ACL as a basic IP ACL (with ID from 1 to 99), extended IP ACL

• ICMP. Select either the Type or Message radio button:

-If you select the Type radio button, note the following:

•The Type and Code fields are enabled only if the protocol is ICMP. Use these

fields to specify a match condition for ICMP packets:

•The IP ACL rule matches the specified ICMP message type. Possible type

numbers are in the range from 0 to 255.

•If you specify information in the Message field, the IP ACL rule matches the

specified ICMP message code. Possible values for the code can be in the

range from 0 to 255.

•If these fields are left empty, it means any.

-If you select the Message radio button, select the type of the ICMP message to

match with the selected IP ACL rule. Specifying a type of message implies that

both the ICMP type and ICMP code are specified. The ICMP message is decoded

into the corresponding ICMP type and ICMP code within the ICMP type.

The IPv4 ICMP message types are echo, echo-reply, host-redirect,

mobile-redirect, net-redirect, net-unreachable, redirect, packet-too-big,

port-unreachable, source-quench, router-solicitation, router-advertisement,

• Fragments. Either select the Enable radio button to allow initial fragments (that is,

the fragment bit is asserted) or leave the default Disable radio button selected to

prevent initial fragments from being used.

This option is not valid for rules that match L4 information such as a TCP port number,

because that information is carried in the initial packet.

• Service Type. Select a service type match condition for the extended IP ACL rule.

The possible options are IP DSCP, IP precedence, and IP TOS , which are alternative

methods to specify a match criterion for the same service type field in the IP header.

Each method uses a different user notation. After you make a selection, you can

specify the appropriate values:

- IP DSCP. This is an optional configuration. Specify the IP DiffServ Code Point

(DSCP) field. The DSCP is defined as the high-order 6 bits of the service type

octet in the IP header. Enter an integer from 0 to 63. To select the IP DSCP, select

one of the DSCP keywords from the menu. To specify a numeric value, select

Other and a field displays in which you can enter numeric value of the DSCP.

- IP Precedence. This is an optional configuration. The IP precedence field in a

packet is defined as the high-order 3 bits of the service type octet in the IP header .

Enter an integer from 0 to 7.

- IP TOS. This is an optional configuration. The IP ToS field in a packet is defined

as all 8 bits of the service type octet in the IP header. The ToS bits value is a

hexadecimal number that is composed of numbers 00 to 09 and AA to FF. The

ToS mask value is a hexadecimal number that is composed of numbers 00 to FF.

The ToS mask denotes the bit positions in the ToS bits value that are used for

comparison against the IP ToS field in a packet.

For example, to check for an IP ToS value for which bit 7 is set and is the most

significant value, for which bit 5 is set, and for which bit 1 is cleared, use a ToS

bits value of 0xA0 and a ToS mask of 0xFF.

Configure an IPv6 ACL

An IPv6 ACL consists of a set of rules that are matched sequentially against a packet. When

a packet meets the match criteria of a rule, the specified rule action (Permit or Deny) is taken,

and the additional rules are not checked for a match. You must specify the interfaces to

which an IPv6 ACL applies, as well as whether it applies to inbound or outbound traffic.

Multiple steps are involved in defining an IPv6 ACL and applying it to the switch:

1. Add an IPv6 ACL ID (see Configure an IPv6 ACL on page 376).

An IPv6 ACL must start with a name string that is up to 31 alphanumeric characters in

length. The name must start with an alphabetic character.

2. Create an IPv6 rule (see Configure rules for an IPv6 ACL on page 379).

3. Associate the IPv6 ACL with one or more interfaces (see Configure IP ACL interface

bindings on page 385).

The Memory Log table displays on the Memory Log page.

The Total number of Messages field displays the number of messages the system logged

in memory. Only the 200 most recent entries are displayed on the page.

The rest of the page displays the Memory Log messages. The format of the log message

is the same for messages that are displayed for the message log, persistent log, or

console log. Messages logged to a collector or relay through syslog support the same

format as well.

The following example shows the standard format for a log message:

<14> Mar 24 05:34:05 10.131.12.183-1 UNKN[2176789276]:

main_login.c(179) 3855 %% HTTP Session 19 initiated for user admin

connected from 10.27.64.122

The number contained in the angle brackets represents the message priority, which is

derived from the following values:

Priority = (facility value × 8) + severity level.

The facility value is usually 1, which means it is a user-level message. Therefore, to

determine the severity level of the message, subtract 8 from the number in the angle

brackets. The sample log message shows a severity level of 6 (informational). For more

information about the severity of a log message, see Manage the server log on

page 412.

The message was generated on March 24 at 5:34:05 a.m. by the switch with an IP

address of 10.131.12.183. The component that generated the message is unknown, but it

came from line 179 of the main_login.c file. This is the 3,855th message logged since

the switch was last booted. The message indicates that the administrator logged on to the

HTTP local browser interface from a host with an IP address of 10.27.64.122.

Configure port mirroring

Port mirroring selects the network traffic for analysis by a network analyzer. This is done for

specific ports of the switch. As such, many switch ports are configured as source ports and

one switch port is configured as a destination port. You can configure how traffic is mirrored

on a source port. Packets that are received on the source port, that are transmitted on a port,

or are both received and transmitted can be mirrored to the destination port.

The packet that is copied to the destination port is in the same format as the original packet

on the wire. This means that if the mirror is copying a received packet, the copied packet is

VLAN tagged or untagged as it was received on the source port. If the mirror is copying a

transmitted packet, the copied packet is VLAN tagged or untagged as it is being transmitted

on the source port.

The Port Mirroring page allows you to view and configure port mirroring on the system.

To globally enable port mirroring, specify the destination port, and specify one or

more source ports:

1. Connect your computer to the same network as the switch.

You can use a WiFi or wired connection to connect your computer to the network, or

connect directly to a switch that is off-network using an Ethernet cable.

Virtual Local Area Networks (VLANs)

A local area network (LAN) can generally be defined as a broadcast domain. Hubs, bridges,

or switches in the same physical segment or segments connect all end node devices. End

nodes can communicate with each other without the need for a router . Routers connect LANs

together, routing the traffic to the appropriate port.

A virtual LAN (VLAN) is a local area network with a definition that maps workstations on

some basis other than geographic location (for example, by department, type of user, or

primary application). To enable traffic to flow between VLANs, traffic must go through a

router, just as if the VLANs were on two separate LANs.

A VLAN is a group of computers, servers, and other network resources that behave as if they

were connected to a single network segment—even though they might not be. For example,

all marketing personnel might be spread throughout a building. Yet if they are all assigned to

a single VLAN, they can share resources and bandwidth as if they were connected to the

same segment. The resources of other departments can be invisible to the marketing VLAN

members, accessible to all, or accessible only to specified individuals, depending on how the

IT manager set up the VLANs.

VLANs present a number of advantages:

•It is easy to do network segmentation. Users who communicate most frequently with

each other can be grouped into common VLANs, regardless of physical location. Each

group’s traffic is contained largely within the VLAN, reducing extraneous traffic and

improving the efficiency of the whole network.

•They are easy to manage. The addition of nodes, as well as moves and other changes,

can be dealt with quickly and conveniently from a management interface rather than from

the wiring closet.

•They provide increased performance. VLANs free up bandwidth by limiting node-to-node

and broadcast traffic throughout the network.

•They ensure enhanced network security. VLANs create virtual boundaries that can be

crossed only through a router. So standard, router-based security measures can be used

to restrict access to each VLAN.

Packets received by the switch are treated in the following way:

•When an untagged packet enters a port, it is automatically tagged with the port’s default

VLAN ID tag number. Each port supports a default VLAN ID setting that is user

configurable (the default setting is 1). The default VLAN ID setting for each port can be

changed on the Port PVID Configuration page. See Configure the port PVID settings on

page 145.

•When a tagged packet enters a port, the tag for that packet is unaffected by the default

VLAN ID setting. The packet proceeds to the VLAN specified by its VLAN ID tag number.

•If the port through which the packet entered is not a member of the VLAN as specified by

the VLAN ID tag, the packet is dropped.

•If the port is a member of the VLAN specified by the packet’s VLAN ID, the packet can be

sent to other ports with the same VLAN ID.

8-Port or 16-Port Gigabit Smart Managed Pro Switch Model GS418TPP, GS510TLP, and GS510TPP

Configuration Examples User Manual450

•Packets leaving the switch are either tagged or untagged, depending on the setting for

that port’s VLAN membership properties. A U for a given port means that packets leaving

the switch from that port are untagged. Inversely, a T for a given port means that packets

leaving the switch from that port are tagged with the VLAN ID that is associated with the

port.

The example given in this section comprises numerous steps to illustrate a wide range of

configurations to help provide an understanding of tagged VLANs.

VLAN configuration examples

This example demonstrates several scenarios of VLAN use and describes how the switch

handles tagged and untagged traffic.

In this example, you create two new VLANs, change the port membership for default VLAN 1,

and assign port members to the two new VLANs:

1. On the Basic VLAN Configuration page (see Configure VLANs on page 139), create the

following VLANs:

•A VLAN with VLAN ID 10.

•A VLAN with VLAN ID 20.

2. On the VLAN Membership page (see Configure VLAN membership on page 142) specify

the VLAN membership as follows:

•For the default VLAN with VLAN ID 1, specify the following members: port 7 (U) and

port 8 (U).

•For the VLAN with VLAN ID 10, specify the following members: port 1 (U), port 2 (U),

and port 3 (T).

•For the VLAN with VLAN ID 20, specify the following members: port 4 (U), port 5 (T),

and port 6 (U).

3. On the Port PVID Configuration page (see Configure the port PVID settings on

page 145), specify the PVID for ports g1 and g4 so that packets entering these ports are

tagged with the port VLAN ID:

•Port g1: PVID 10

•Port g4: PVID 20

4. With the VLAN configuration that you set up, the following situations produce results as

described:

•If an untagged packet enters port 1, the switch tags it with VLAN ID 10. The packet

can access port 2 and port 3. The outgoing packet is stripped of its tag to leave port 2

as an untagged packet. For port 3, the outgoing packet leaves as a tagged packet

with VLAN ID 10.

•If a tagged packet with VLAN ID 10 enters port 3, the packet can access port 1 and

port 2. If the packet leaves port 1 or port 2, it is stripped of its tag to leave the switch

as an untagged packet.

•If an untagged packet enters port 4, the switch tags it with VLAN ID 20. The packet

can access port 5 and port 6. The outgoing packet is stripped of its tag to become an

8-Port or 16-Port Gigabit Smart Managed Pro Switch Model GS418TPP, GS510TLP, and GS510TPP

Configuration Examples User Manual451

untagged packet as it leaves port 6. For port 5, the outgoing packet leaves as a

tagged packet with VLAN ID 20.

Access control lists (ACLs)

ACLs ensure that only authorized users can access specific resources while blocking off any

unwarranted attempts to reach network resources.

ACLs are used to provide traffic flow control, restrict contents of routing updates, decide

which types of traffic are forwarded or blocked, and provide security for the network. ACLs

are normally used in firewall routers that are positioned between the internal network and an

external network, such as the Internet. They can also be used on a router positioned between

two parts of the network to control the traffic entering or exiting a specific part of the internal

network. The added packet processing required by the ACL feature does not affect switch

performance. That is, ACL processing occurs at wire speed.

Access lists are sequential collections of permit and deny conditions. This collection of

conditions, known as the filtering criteria, is applied to each packet that is processed by the

switch or the router. The forwarding or dropping of a packet is based on whether or not the

packet matches the specified criteria.

Traffic filtering requires the following two basic steps:

1. Create an access list definition.

The access list definition includes rules that specify whether traffic matching the criteria is

forwarded normally or discarded. Additionally, you can assign traffic that matches the

criteria to a particular queue or redirect the traffic to a particular port. A default deny all

rule is the last rule of every list.

2. Apply the access list to an interface in the inbound direction.

The switch allow ACLs to be bound to physical ports and LAGs. The switch software

supports MAC ACLs and IP ACLs.

MAC ACL example configuration

The following example shows how to create a MAC-based ACL that permits Ethernet traffic

from the Sales department on specified ports and denies all other traffic on those ports.

1. On the MAC ACL page, create an ACL with the name Sales_ACL for the Sales

department of your network (see Configure a MAC ACL on page 352).

By default, this ACL is bound on the inbound direction, which means that the switch

examines traffic as it enters the port.

2. On the MAC Rules page, create a rule for the Sales_ACL with the following settings:

•Sequence Number. 1

• Action. Permit

8-Port or 16-Port Gigabit Smart Managed Pro Switch Model GS418TPP, GS510TLP, and GS510TPP

Configuration Examples User Manual452

• Assign Queue ID. 0

• Match Every. False

• CoS. 0

• Destination MAC. 01:02:1A:BC:DE:EF

• Destination MAC Mask. 00:00:00:00:FF:FF

• EtherType. User Value.

•Source MAC. 02:02:1A:BC:DE:EF

• Source MAC Mask. 00:00:00:00:FF:FF

• VLAN ID. 2

For more information about MAC ACL rules, see Configure MAC ACL rules on

page 355.

3. On the MAC Binding Configuration page, assign the Sales_ACL to the interface Gigabit

ports 6, 7, and 8, and then click the Apply button. (See Configure MAC bindings on

page 359.)

You can assign an optional sequence number to indicate the order of this access list

relative to other access lists if any are already assigned to this interface and direction.

4. The MAC Binding Table displays the interface and MAC ACL binding information. (See

View or delete MAC ACL bindings in the MAC binding table on page 360.)

The ACL named Sales_ACL looks for Ethernet frames with destination and source MAC

addresses and MAC masks defined in the rule. Also, the frame must be tagged with VLAN ID

2, which is the Sales department VLAN. The CoS value of the frame must be 0, which is the

default value for Ethernet frames. Frames that match this criteria are permitted on interfaces

6, 7, and 8 and are assigned to the hardware egress queue 0, which is the default queue. All

other traffic is explicitly denied on these interfaces. To allow additional traffic to enter these

ports, you must add a new Permit rule with the desired match criteria and bind the rule to

interfaces 6, 7, and 8.

Basic IP ACL example configuration

The following example shows how to create an IP-based ACL that prevents any IP traffic

from the Finance department from being allowed on the ports that are associated with other

departments. Traffic from the Finance department is identified by each packet’s network IP

address.

1. On the IP ACL page, create a new IP ACL with an IP ACL ID of 1. (See Configure a

basic or extended IPv4 ACL on page 361.)

2. On the IP Rules page, create a rule for IP ACL 1 with the following settings:

•Sequence Number. 1

• Action. Deny

• Assign Queue ID. 0 (optional: 0 is the default value)

• Match Every. False

8-Port or 16-Port Gigabit Smart Managed Pro Switch Model GS418TPP, GS510TLP, and GS510TPP

Configuration Examples User Manual453

• Source IP Address. 192.168.187.0

• Source IP Mask. 255.255.0

For additional information about IP ACL rules, see Configure rules for a basic IPv4 ACL

on page 364.

3. Click the Add button.

4. On the IP Rules page, create a second rule for IP ACL 1 with the following settings:

•Sequence Number. 2

• Action. Permit

• Match Every. True

5. Click the Add button.

6. On the IP Binding Configuration page, assign ACL ID 1 to the interface Gigabit ports 2, 3,

and 4, and assign a sequence number of 1. (See Configure IP ACL interface bindings on

page 385.)

By default, this IP ACL is bound on the inbound direction, so it examines traffic as it

enters the switch.

7. Click the Apply button.

8. Use the IP Binding Table page to view the interfaces and IP ACL binding information. (See

View or delete IP ACL bindings in the IP ACL binding table on page 387)

The IP ACL in this example matches all packets with the source IP address and subnet mask

of the Finance department’s network and deny it on the Ethernet interfaces 2, 3, and 4 of the

switch. The second rule permits all non-Finance traffic on the ports. The second rule is

required because an explicit deny all rule exists as the lowest priority rule.

Differentiated Services (DiffServ)

Standard IP-based networks are designed to provide best effort data delivery service. Best

effort service implies that the network delivers the data in a timely fashion, although there is

no guarantee that it does. During times of congestion, packets might be delayed, sent

sporadically, or dropped. For typical Internet applications, such as email and file transfer, a

slight degradation in service is acceptable and in many cases unnoticeable. However, any

degradation of service can negatively affect applications with strict timing requirements, such

as voice or multimedia.

Quality of Service (QoS) can provide consistent, predictable data delivery by distinguishing

between packets with strict timing requirements from those that are more tolerant of delay.

Packets with strict timing requirements are given special treatment in a QoS-capable

network. With this in mind, all elements of the network must be QoS capable. If one node

cannot meet the necessary timing requirements, this creates a deficiency in the network path

and the performance of the entire packet flow is compromised.

8-Port or 16-Port Gigabit Smart Managed Pro Switch Model GS418TPP, GS510TLP, and GS510TPP

Configuration Examples User Manual454

Two basic types of QoS are supported:

• Integrated Services. Network resources are apportioned based on request and are

reserved (resource reservation) according to network management policy (RSVP, for

example).

• Differentiated Services. Network resources are apportioned based on traffic

classification and priority, giving preferential treatment to data with strict timing

requirements.

The switch supports DiffServ.

The DiffServ feature contains a number of conceptual QoS building blocks that you can use

to construct a differentiated service network. Use these same blocks in dif ferent ways to build

other types of QoS architectures.

You must configure three key QoS building blocks for DiffServ:

•Class

•Policy

•Service (the assignment of a policy to a directional interface)

Class

You can classify incoming packets at Layers 2, 3, and 4 by inspecting the following

information for a packet:

•Source/destination MAC address

•EtherType

•Class of Service (802.1p priority) value (first/only VLAN tag)

•VLAN ID range (first/only VLAN tag)

•Secondary 802.1p priority value (second/inner VLAN tag)

•Secondary VLAN ID range (second/inner VLAN tag)

•IP Service Type octet (also known as: ToS bits, Precedence value, DSCP value)

•Layer 4 protocol (TCP, UDP and so on)

•Layer 4 source/destination ports

•Source/destination IP address

From a DiffServ point of view, two types of classes exist:

•DiffServ traffic classes

•DiffServ service levels/forwarding classes

8-Port or 16-Port Gigabit Smart Managed Pro Switch Model GS418TPP, GS510TLP, and GS510TPP

Configuration Examples User Manual455

DiffServ traffic classes

With DiffServ, you define which traffic classes to track on an ingress interface. You can define

simple BA classifiers (DSCP) and a wide variety of multifield (MF) classifiers:

•Layer 2; Layers 3, 4 (IP only)

•Protocol-based

•Address-based

You can combine these classifiers with logical AND or OR operations to build complex

MF-classifiers (by specifying a class type of all or any, respectively). That is, within a single

class, multiple match criteria are grouped together as an AND expression or a sequential OR

expression, depending on the defined class type. Only classes of the same type can be

nested; class nesting does not allow for the negation (exclude option) of the referenced

class.

To configure DiffServ, you must define service levels, namely the forwarding classes/PHBs

identified by a given DSCP value, on the egress interface. You define these service levels by

configuring BA classes for each.

Creating policies

Use DiffServ policies to associate a collection of classes that you configure with one or more

QoS policy statements. The result of this association is referred to as a policy.

From a DiffServ perspective, two types of policies exist:

• T raffic Conditioning Policy. A policy applied to a DiffServ traffic class

• Service Provisioning Policy. A policy applied to a DiffServ service level

You must manually configure the various statements and rules used in the traffic conditioning

and service provisioning policies to achieve the desired Traffic Conditioning Specification

(TCS) and the Service Level Specification (SLS) operation, respectively.

Traffic conditioning policy

Traffic conditioning pertains to actions performed on incoming traffic. Several distinct QoS

actions are associated with traffic conditioning:

• Dropping. Drop a packet upon arrival. This is useful for emulating access control list

operation using DiffServ, especially when DiffServ and ACL cannot coexist on the same

interface.

• Marking IP DSCP or IP Precedence. Marking/re-marking the DiffServ code point in a

packet with the DSCP value representing the service level associated with a particular

DiffServ traffic class. Alternatively, the IP precedence value of the packet can be

marked/re-marked.

• Marking CoS (802.1p). Sets the 3-bit priority field in the first/only 802.1p header to a

specified value when packets are transmitted for the traffic class. An 802.1p header is

inserted if it does not already exist. This is useful for assigning a Layer 2 priority level

8-Port or 16-Port Gigabit Smart Managed Pro Switch Model GS418TPP, GS510TLP, and GS510TPP

Configuration Examples User Manual456

based on a DiffServ forwarding class (such as the DSCP or IP precedence value)

definition to convey some QoS characteristics to downstream switches that do not

routinely look at the DSCP value in the IP header.

• Policing. A method of constraining incoming traffic associated with a particular class so

that it conforms to the terms of the TCS. Special treatment can be applied to out-of-profile

packets that are either in excess of the conformance specification or are nonconformant.

The DiffServ feature supports the following types of traffic policing treatments (actions):

• drop. The packet is dropped.

•mark cos. The 802.1p user priority bits are (re)marked and forwarded.

•mark dscp. The packet DSCP is (re)marked and forwarded.

•mark prec. The packet IP Precedence is (re)marked and forwarded.

•send. The packet is forwarded without DiffServ modification.

Color Mode Awareness. Policing in the DiffServ feature uses either color blind or color

aware mode. Color blind mode ignores the coloration (marking) of the incoming packet.

Color aware mode takes into consideration the current packet marking when the switch

determines the policing outcome. An auxiliary traffic class is used in conjunction with the

policing definition to specify a value for one of the 802.1p, secondary 802.1p, IP DSCP, or

IP precedence fields designating the incoming color value to be used as the conforming

color. You can also specify the color of traffic that exceeds the threshold.

• Counting. Updating octet and packet statistics to keep track of data handling along traffic

paths within DiffServ. In this DiffServ feature, counters are not explicitly configured by the

user, but are designed into the system based on the DiffServ policy being created. For

more information, see Monitor the switch and the ports on page 392.

• Assigning QoS Queue. Directs a traffic stream to the specified QoS queue. This allows a

traffic classifier to specify which one of the supported hardware queues are used for

handling packets belonging to the class.

• Redirecting. Forces a classified traffic stream to a specified egress port (physical or

LAG). This can occur in addition to any marking or policing action. It can also be specified

along with a QoS queue assignment.

DiffServ example configuration

To create a DiffServ class and policy and attach them to a switch interface, follow these

steps:

1. On the QoS Class Configuration page, create a new class with the following settings:

• Class Name. Class1

9. On the Service Configuration page, select the check box next to interfaces g7 and g8 to

attach the policy to these interfaces, and then click the Apply button. (See Configure the

DiffServ service interface on page 283.)

All UDP packet flows destined to the 192.12.2.0 network with an IP source address from the

192.12.1.0 network that include a Layer 4 Source port of 4567 and Destination port of 4568

from this switch on ports 7 and 8 are assigned to hardware queue 3.

On this network, traffic from streaming applications uses UDP port 4567 as the source and

4568 as the destination. This real-time traffic is time sensitive, so it is assigned to a

high-priority hardware queue. By default, data traffic uses hardware queue 0, which is

designated as a best-effort queue.

Also the confirmed action on this flow is to send the packets with a committed rate of

1000000 Kbps and burst size of 128 KB. Packets that violate the committed rate and burst

size are dropped.

802.1X access control

Local area networks (LANs) are often deployed in environments that permit unauthorized

devices to be physically attached to the LAN infrastructure, or permit unauthorized users to

attempt to access the LAN through equipment already attached. In such environments you

might want to restrict access to the services offered by the LAN to those users and devices

that are permitted to use those services.

Port-based network access control makes use of the physical characteristics of LAN

infrastructures to provide a means of authenticating and authorizing devices attached to a

LAN port with point-to-point connection characteristics. If the authentication and authorization

process fails, access control prevents access to that port. In this context, a port is a single

point of attachment to the LAN, such as a port of a MAC bridge and an association between

stations or access points in IEEE 802.11 wireless LANs.

The IEEE 802.11 standard describes an architectural framework within which authentication

and consequent actions take place. It also establishes the requirements for a protocol

between the authenticator (the system that passes an authentication request to the

authentication server) and the supplicant (the system that requests authentication), as well

as between the authenticator and the authentication server.

The switch supports a guest VLAN, which allows unauthenticated users limited access to the

network resources.

Note: You can use QoS features to provide rate limiting on the guest VLAN

to limit the network resources that the guest VLAN provides.

Another 802.1X feature is the ability to configure a port to enable or disable EAPoL packet

forwarding support. You can disable or enable the forwarding of EAPoL when 802.1X is

disabled on the device.

The ports of an 802.1X authenticator switch provide the means by which it can offer services

to other systems reachable through the LAN. Port-based network access control allows the

operation of a switch’s ports to be controlled to ensure that access to its services is permitted

only by systems that are authorized to do so.

Port access control provides a means of preventing unauthorized access by supplicants to

the services offered by a system. Control over the access to a switch and the LAN to which it

is connected can be desirable when you restrict access to publicly accessible bridge ports or

to restrict access to departmental LANs.

8-Port or 16-Port Gigabit Smart Managed Pro Switch Model GS418TPP, GS510TLP, and GS510TPP

Configuration Examples User Manual459

Access control is achieved by enforcing authentication of supplicants that are attached to an

authenticator's controlled ports. The result of the authentication process determines whether

the supplicant is authorized to access services on that controlled port.

A port access entity (PAE) is able to adopt one of two distinct roles within an access control

interaction:

1. Authenticator. A port that enforces authentication before allowing access to services

available through that port.

2. Supplicant. A port that attempts to access services offered by the authenticator.

Additionally, there exists a third role:

3. Authentication server. Performs the authentication function necessary to check the

credentials of the supplicant on behalf of the authenticator.

All three roles are required for you to complete an authentication exchange.

The switch supports the authenticator role only, in which the PAE is responsible for

communicating with the supplicant. The authenticator PAE is also responsible for submitting

the information received from the supplicant to the authentication server for the credentials to

be checked, which determines the authorization state of the port. The authenticator PAE

controls the authorized/unauthorized state of the controlled port depending on the outcome

of the RADIUS-based authentication process.

802.1X example configuration

This example shows how to configure the switch so that 802.1X-based authentication is

required on the ports in a corporate conference room (1/0/5–1/0/8). These ports are available

to visitors and must be authenticated before access is granted to the network. The

authentication is handled by an external RADIUS server. When the visitor is successfully

authenticated, traffic is automatically assigned to the guest VLAN. This example assumes

that a VLAN was configured with a VLAN ID of 150 and VLAN name of Guest.

1. On the Port Authentication page, select ports 1/0/5, 1/0/6, 1/0/7, and 1/0/8.

2. From the Port Control menu, select Unauthorized.

The selection from the Port Control menu for all other ports on which authentication is

not needed must be Authorized. When the selection from the Port Control menu is

Authorized, the port is unconditionally put in a force-authorized state and does not

require any authentication. When the selection from the Port Control menu is Auto, the

authenticator PAE sets the controlled port mode.

3. In the Guest VLAN field for ports 1/0/5–1/0/8, enter 150 to assign these ports to the guest

VLAN.

You can configure additional settings to control access to the network through the ports.

See Configure a port security interface on page 337 for information about the settings.

4. Click the Apply button.

5. On the 802.1X Configuration page, set the port based authentication state and guest VLAN

mode to Enable, and then the Apply button. (See Configure the global port security

mode on page 336.)

This example uses the default values for the port authentication settings, but you can

configure several additional settings. For example, the EAPOL Flood Mode field allows

you to enable the forwarding of EAPoL frames when 802.1X is disabled on the device.

6. On the RADIUS Server Configuration page, configure a RADIUS server with the following

settings:

• Server Address. 192.168.10.23

• Secret Configured. Yes

• Secret. secret123

• Active. Primary

For more information, see Manage the RADIUS settings on page 290.

7. Click the Add button.

8. On the Authentication List page, configure the default list to use RADIUS as the first

authentication method. (See Configure authentication lists on page 302.)

This example enables 802.1X-based port security on the switch and prompts the hosts

connected on ports g5-g8 for an 802.1X-based authentication. The switch passes the

authentication information to the configured RADIUS server.

Multiple Spanning Tree Protocol

Spanning Tree Protocol (STP) runs on bridged networks to help eliminate loops. If a bridge

loop occurs, the network can become flooded with traffic. IEEE 802.1s Multiple Spanning

Tree Protocol (MSTP) supports multiple instances of spanning tree to efficiently channel

VLAN traffic over different interfaces. Each instance of the spanning tree behaves in the

manner specified in IEEE 802.1w, Rapid Spanning Tree, with slight modifications in the

working but not the end effect (chief among the effects is the rapid transitioning of the port to

the forwarding state).

The difference between the RSTP and the traditional STP (IEEE 802.1D) is the ability to

configure and recognize full-duplex connectivity and ports that are connected to end stations,

resulting in rapid transitioning of the port to the Forwarding state and the suppression of

Topology Change Notification. These features are represented by the pointtopoint and

edgeport parameters. MSTP is compatible to both RSTP and STP. It behaves in a way that is

appropriate for STP and RSTP bridges.

An MSTP bridge can be configured to behave entirely as a RSTP bridge or an STP bridge.

So, an IEEE 802.1s bridge inherently also supports IEEE 802.1w and IEEE 802.1D.

The MSTP algorithm and protocol provide simple and full connectivity for frames assigned to

any given VLAN throughout a bridged LAN comprising arbitrarily interconnected networking

devices, each operating MSTP, STP, or RSTP. MSTP allows frames assigned to different

VLANs to follow separate paths, each based on an independent Multiple Spanning Tree

Instance (MSTI), within Multiple Spanning Tree (MST) regions composed of LANs and or

MSTP bridges. These regions and the other bridges and LANs are connected into a single

Common Spanning Tree (CST). (IEEE DRAFT P802.1s/D13)

MSTP connects all bridges and LANs with a single Common and Internal Spanning Tree

(CIST). The CIST supports the automatic determination of each MST region, choosing its

maximum possible extent. The connectivity calculated for the CIST provides the CST for

interconnecting these regions, and an Internal Spanning Tree (IST) within each region.

MSTP ensures that frames with a given VLAN ID are assigned to one and only one of the

MSTIs or the IST within the region, that the assignment is consistent among all the

networking devices in the region, and that the stable connectivity of each MSTI and IST at

the boundary of the region matches that of the CST. The stable active topology of the bridged

LAN with respect to frames consistently classified as belonging to any given VLAN thus

simply and fully connects all LANs and networking devices throughout the network, though

frames belonging to different VLANs can take different paths within any region, per IEEE

DRAFT P802.1s/D13.

All bridges, whether they use STP, RSTP, or MSTP, send information in configuration

messages through Bridge Protocol Data Units (BPDUs) to assign port roles that determine

each port’s participation in a fully and simply connected active topology based on one or

more spanning trees. The information communicated is known as the spanning tree priority

vector. The BPDU structure for each of these dif ferent protocols is dif ferent. An MSTP bridge

transmits the appropriate BPDU depending on the received type of BPDU from a particular

port.

8-Port or 16-Port Gigabit Smart Managed Pro Switch Model GS418TPP, GS510TLP, and GS510TPP

Configuration Examples User Manual462

An MST region comprises of one or more MSTP bridges with the same MST configuration

identifier, using the same MSTIs, and without any bridges attached that cannot receive and

transmit MSTP BPDUs. The MST configuration identifier includes the following components:

1. Configuration identifier format selector

2. Configuration name

3. Configuration revision level

4. Configuration digest: 16-byte signature of type HMAC-MD5 created from the MST

Configuration Table (a VLAN ID to MSTID mapping)

Because multiple instances of spanning tree exist, an MSTP state is maintained on a

per-port, per-instance basis (or on a per-port, per-VLAN basis, as any VLAN can be in one

and only one MSTI or CIST). For example, port A can be forwarding for instance 1 while

discarding for instance 2. The port states changed since IEEE 802.1D specification.

To support multiple spanning trees, configure an MSTP bridge with an unambiguous

assignment of VLAN IDs (VIDs) to spanning trees. For such a configuration, ensure the

following:

1. The allocation of VIDs to FIDs is unambiguous.

2. Each FID that is supported by the bridge is allocated to exactly one spanning tree instance.

The combination of VID to FID and then FID to MSTI allocation defines a mapping of VIDs to

spanning tree instances, represented by the MST Configuration Table.

With this allocation we ensure that every VLAN is assigned to one and only one MSTI. The

CIST is also an instance of spanning tree with an MSTID of 0.

VIDs might be not be allocated to an instance, but every VLAN must be allocated to one of

the other instances of spanning tree.

The portion of the active topology of the network that connects any two bridges in the same

MST region traverses only MST bridges and LANs in that region, and never bridges of any

kind outside the region. In other words, connectivity within the region is independent of

external connectivity.

MSTP example configuration

This example shows how to create an MSTP instance from the switch. The example network

includes three different switches that serve dif ferent locations in the network. In this example,

ports 1/0/1–1/0/5 are connected to host stations, so those links are not subject to network

loops. Ports 1/0/6–1/0/8 are connected across switches 1, 2, and 3.

8-Port or 16-Port Gigabit Smart Managed Pro Switch Model GS418TPP, GS510TLP, and GS510TPP

Configuration Examples User Manual463

Figure 2. MSTP example configuration

Perform the following procedures on each switch to configure MSTP:

1. On the VLAN Configuration page, create VLANs 300 and 500 (see Configure the VLAN

Settings on page 140).

2. On the VLAN Membership page, include ports 1/0/1–1/0/8 as tagged (T) or untagged (U)

members of VLAN 300 and VLAN 500 (see Configure the VLAN Settings on page 140).

3. On the STP Configuration page, enable the Spanning Tree State option (see Configure the

STP settings and view the STP status on page 164).

Use the default values for the rest of the STP configuration settings. By default, the STP

operation mode is MSTP and the configuration name is the switch MAC address.

4. On the CST Configuration page, set the bridge priority value for each of the three switches

to force Switch 1 to be the root bridge:

• Switch 1. 4096

• Switch 2. 12288

• Switch 3. 20480

Note: Bridge priority values are multiples of 4096.

If you do not specify a root bridge and all switches are assigned the same bridge priority

value, the switch with the lowest MAC address is elected as the root bridge (see

Configure the CST settings on page 166).

5. On the CST Port Configuration page, select ports 1/0/1–1/0/8 and select Enable from the

STP Status menu (see Configure the CST port settings on page 167).

6. Click the Apply button.

8-Port or 16-Port Gigabit Smart Managed Pro Switch Model GS418TPP, GS510TLP, and GS510TPP

Configuration Examples User Manual464

7. Select ports 1/0/1–1/0/5 (edge ports), and select Enable from the Fast Link menu.

Since the edge ports are not at risk for network loops, ports with Fast Link enabled

transition directly to the forwarding state.

8. Click the Apply button.

You can use the CST Port Status page to view spanning tree information about each port.

9. On the MST Configuration page, create a MST instances with the following settings:

• MST ID. 1

• Priority. Use the default (32768)

• VLAN ID. 300

For more information, see View Rapid STP Information on page 171.

10. Click the Add button.

11. Create a second MST instance with the following settings

• MST ID. 2

• Priority. 49152

• VLAN ID. 500

12. Click the Add button.

In this example, assume that Switch 1 became the root bridge for the MST instance 1, and

Switch 2 became the root bridge for MST instance 2. Switch 3 supports hosts in the sales

department (ports 1/0/1, 1/0/2, and 1/0/3) and in the HR department (ports 1/0/4 and 1/0/5).

Switches 1 and 2 also include hosts in the sales and HR departments. The hosts connected

from Switch 2 use VLAN 500, MST instance 2 to communicate with the hosts on Switch 3

directly. Likewise, hosts of Switch 1 use VLAN 300, MST instance 1 to communicate with the

hosts on Switch 3 directly.

The hosts use different instances of MSTP to effectively use the links across the switch. The

same concept can be extended to other switches and more instances of MSTP.

VLAN routing interfaces

VLANs divide broadcast domains in a LAN environment. When hosts in one VLAN must

communicate with hosts in another VLAN, the traffic must be routed between them. This is

known as inter-VLAN routing. On the switch, it is accomplished by creating Layer 3 interfaces

(switch virtual interfaces [SVI]).

When a port is enabled for bridging (the default) rather than routing, all normal bridge

processing is performed for an inbound packet, which is then associated with a VLAN. Its

MAC destination address (MAC DA) and VLAN ID are used to search the MAC address

table. If routing is enabled for the VLAN, and the MAC DA of an inbound unicast packet is

that of the internal bridge-router interface, the packet is routed. An inbound multicast packet

8-Port or 16-Port Gigabit Smart Managed Pro Switch Model GS418TPP, GS510TLP, and GS510TPP

Configuration Examples User Manual465

is forwarded to all ports in the VLAN, plus the internal bridge-router interface, if it was

received on a routed VLAN.

Since a port can be configured to belong to more than one VLAN, VLAN routing might be

enabled for all of the VLANs on the port, or for a subset. VLAN routing can be used to allow

more than one physical port to reside on the same subnet. It could also be used when a

VLAN spans multiple physical networks, or when additional segmentation or security is

required. A port can be either a VLAN port or a router port, but not both. However, a VLAN

port can be part of a VLAN that is itself a router port.

Complete these steps to configure a switch to perform interVLAN routing:

1. Use the IP Configuration page to enable routing on the switch.

For more information about this step, see Configure the router settings on page 220.

2. Determine the IP addresses that you want to assign to the VLAN interface on the switch.

For the switch to be able to route between the VLANs, the VLAN interfaces must be

configured with an IP address. When the switch receives a packet destined for another

subnet/VLAN, the switch looks at the routing table to determine where to forward the

packet. The packet is then passed to the VLAN interface of the destination. It is then sent

to the port where the end device is attached.

3. Use the VLAN Routing Wizard page to create a routing VLAN, configure the IP address and

subnet mask, and add the member ports.

For more information about this step, see Create a routing interface with the VLAN Static

Routing Wizard on page 241.

In the following figure, VLAN 300 is created with IP address 10.1.2.1 and subnet mask

255.255.255.0. Port r1 is a member port. (For more information about this page, see

Manage a VLAN routing interface on page 243.)
