Switch management options and default

management mode

If you prefer, you can use the switch as a plug-and-play device, so you do not need to set up

a custom configuration. Just connect power, connect to your network and to your other

devices, and you’re done.

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

control the network. The device UI is enabled by default, allowing you to configure the switch

and the network from a web browser. If you are an Insight Premium or Pro subscriber, you

can choose to manage the switch by using the NETGEAR Insight app on a smartphone or

tablet or from the Insight Cloud portal that is available from a web browser on your

Windows-based computer, Mac, or tablet.

The switch provides the following management options that let you discover the switch on the

About on-network and off-network access

You can access the switch either on-network or off-network:

• On-network and connected to the Internet. When you use the device UI, for easiest

access, we recommend that you cable the switch to a network that is connected to the

Internet and that includes 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

to connect to the device UI. We refer to this setup as on-network or online.

For more information, see Access the switch on-network and connected to the Internet

on page 20).

• Off-network and not connected to the Internet. You can also configure the switch

connected directly only to the computer that you are using to configure it. That is, the

switch is not connected to the network and the Internet. We refer to this setup as

off-network or offline. If your network does not include a DHCP server (or a router that

functions as a DHCP server), you must access the switch off-network.

For more information, see Access the switch off-network and not connected to the

Internet on page 28.

Note: We recommend that you register the switch to activate your warranty.

For more information, see Register the switch on page 31.

7. Ensure that the Admin Mode Enable radio button is selected.

8. Determine how the switch acquires an IPv6 address:

• IPv6 Address Auto Configuration Mode. When this mode is enabled, the network

interface can acquire an IPv6 address through IPv6 Neighbor Discovery Protocol

(NDP) and through the use of router advertisement messages. When this mode is

disabled, the network interface does not use the native IPv6 address

auto-configuration features to acquire an IPv6 address. Auto-configuration can be

enabled only when DHCPv6 is not enabled on any of the management interfaces.

• DHCPv6. Next to Current Network Configuration Protocol, select the DHCPv6 radio

button to enable the DHCPv6 client on the interface. The switch attempts to acquire

network information from a DHCPv6 server. Selecting the None radio button disables

the DHCPv6 client on the network interface.

The local clock can be set to SNTP only if the following two conditions are met:

•An SNTP server is configured.

•The switch can contact the SNTP server.

8. Next to Client Mode, select the mode of operation of the SNTP client:

• Unicast. SNTP operates in a point-to-point fashion. A unicast client sends a request

to a designated server at its unicast address and expects a reply from which it can

determine the time and, optionally, the round-trip delay and local clock offset relative

to the server.

• Broadcast. SNTP operates in the same manner as multicast mode but uses a local

broadcast address instead of a multicast address. The broadcast address provides a

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.

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

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.

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

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

10. In the 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 range is from 1 to 3. The default value is 1.

(PoE) configuration settings and the PoE settings for each port.

Note: For more information about PoE, see the hardware installation guide,

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

PoE concepts

Models GS110TPv3 and GS110TPP include eight PoE plus (PoE+) ports.

The following table shows the capacity for each model.

Table 19. PoE capacities for models GS110TPv3 and GS110TPP

Per Individual Port

Maximum Power Budget Across

All Active PoE+ Ports

GS110TPv3 30W PoE+ (IEEE 802.3at) 55W

GS110TPP 30W PoE+ (IEEE 802.3at) 120W.

Note: By purchasing and connecting the

NETGEAR optional power adapter model

EPS200W, you can upgrade the PoE

power budget to 190W.

8-Port Gigabit (PoE+) Ethernet Smart Managed Pro Switch with (2 SFP or 2 Copper Ports and)

Cloud Management

Configure System Information User Manual93

By default, supplied power is prioritized in ascending port order, up to the total power budget

of the device. If the power requirements for the attached devices exceed the total power

budget of the switch, the power to the device on the highest-numbered PoE+ port is disabled

to make sure that the devices connected to the higher-priority, lower-numbered PoE+ ports

are supported first.

It is important to note that although a device is listed as an 802.3at (PoE+) powered or

802.3af (PoE) powered device, it might not require the maximum power limit that is specified.

Many devices require less power, allowing all eight PoE+ ports to be active simultaneously,

when the devices correctly report their PoE class to the switch.

Device class power requirements

PoE and PoE+ use Ethernet cables to supply power to PoE-capable devices on the network,

such as WiFi access points, IP cameras, VoIP phones, and switches. The switch is compliant

with the IEEE 802.3at standard (PoE+) and backward compatible with the IEEE 802.3af

standard (PoE). The switch can pass power through to any powered device (PD) that

supports these standards. PoE and PoE+ let you power such devices without the need for a

separate power supply.

The switch supports a Plug-and-Play process by which it detects the type of device that is

connected to one of its PoE+ ports and whether that device needs power and how much so

that the switch can provide the correct power to the device.

During the Plug-and-Play process, the connected device can provide its Class response to

the switch in many ways, depending on how the vendor programmed the device.

The following table shows the device classes for PoE+ devices adhering to the IEEE 802.3at

standard. The device classes for PoE devices adhering to the IEEE 802.3af standard are

identical with the exception that Device Class 4 is not supported.

Table 20. PoE and PoE+ device class power allocation

0 PoE and PoE+ 0.44W–12.95W 15.4W 16.2W

1 PoE and PoE+ 0.44W–3.84W 4.0W 4.2W

2 PoE and PoE+ 3.84W–6.49W 7.0W 7.4W

3 PoE and PoE+ 6.49W–12.95W 15.4W 16.2W

4 PoE+ only 12.95W–25.5W 30.0W 31.6W

Power allocation and power budget concepts

The switch is a smart switch in that it can allocate the required power to a connected device

by using a prioritization scheme: By default, power is supplied in ascending port order (that

is, lower port numbers are served first) until the power budget is consumed and insufficient

8-Port Gigabit (PoE+) Ethernet Smart Managed Pro Switch with (2 SFP or 2 Copper Ports and)

Cloud Management

Configure System Information User Manual94

power remains to allocate to the next device. When less than 7W of PoE power is available

on a port, the port PoE LED lights yellow, and the attached device does not receive power

from the port. However, the switch continues to send data through the port connection.

The switch is also a smart switch in that it can override the IEEE power classification of a

powered device (PD): If the PD consumes less power than required by its power

classification, the switch provides only the power that the PD consumes instead of the power

that is required by the PD’s power classification.

If some PoE+ ports are in use and deliver power, you can calculate the available power

budget for the other PoE+ ports by subtracting the consumed (that is, delivered power) from

the total available power budget. (For information about the total available power budget, see

PoE concepts on page 92.)

An example for model GS110TPv3:

Port 1 delivers 4.4W to a PD. The available power budget is 50.6W (55W–4.4W).

An example for model GS110TPP:

A Class 4 PD is attached to Port 1, a Class 2 PD to Port 2, and another Class 4 PD to Port 3.

However, the PDs consume less power than defined by their classes: The PD attached to

Port 1 consumes 7.3W, the PD attached to Port 2 consumes 4.7W, and the PD attached to

Port 3 consumes 8.9W. So even though the switch provides power to two Class 4 devices

and one Class 3 device, if the default power adapter is installed, the available power budget

is 99.1W (120W–7.3–4.7–8.9W).

To determine the delivered power by a PoE+ port:

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.

Activate the new PoE budget for an optional or

replacement power adapter (model GS110TPP)

Model GS110TPP supports NETGEAR FlexPoE power. This feature allows for an

interchangeable power adapter so that you can change your PoE power budget.

Model GS110TPP comes with a 130W power adapter that provides a PoE power budget of

120W.

If you purchase and connect the NETGEAR optional power adapter model EPS200W, you

can upgrade the PoE power budget to 190W. After you change the power adapter, you must

use the device UI to activate the new power adapter that you connected to the switch.

Note: If you do not change the power adapter, you do not need to select the

PoE budget and power adapter in the device UI. By default, the 130W

power adapter is selected, and model GS110TPP provides a PoE

power budget of 120W.

Perform the following task after you disconnect the old power adapter from the switch,

connect the new power adapter to the switch, and start the switch.

•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.

10. 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.

11. 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.

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

The range is 3,000–30,000 mW. The default is 30,000 mW.

13. From the Detection Type menu, select how the port detects the attached PD:

• IEEE 802. The port performs a 4-point resistive detection. This is the default setting.

• 4pt802.3af+legacy. The port performs a 4-point resistive detection, and if required,

continues with legacy detection.

• Legacy. The port performs legacy detection.

Configure SNMP

You can configure SNMP settings for SNMPv1/v2 and SNMPv3. The switch software

supports the configuration of SNMP groups and users that can manage traps that the SNMP

agent generates.

The switch uses both standard public MIBs for standard functionality and private MIBs that

support additional switch functionality. All private MIBs begin with a hyphen (-) prefix. The

main object for interface configuration is in -SWITCHING-MIB, which is a private MIB. Some

interface configurations also involve objects in the public MIB, IF-MIB.

Configure the SNMPv1 and SNMPv2 community

Only the communities that you define can access to the switch using the SNMP V1 and

SNMP V2 protocols. Only those communities with read/write level access can be used to

change the configuration using SNMP.

Add an SNMP community:

To add an SNMP community:

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.

Fault Status The error description when the PoE port is in a fault state:

• 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.

• Startup Failure. The PD that is connected to the port failed to start up. In this

condition, the port does not provide power.

• Over Voltage. The port was denied power because of a over-voltage lockout.

• Under Voltage. The port was denied power because of an under-voltage

lockout.

• Thermal Shutdown. The port detected a thermal temperature fault, preventing

the port from providing power.

Configure Link Layer Discovery Protocol

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

on an 802 LAN to advertise major capabilities and physical descriptions. A network manager

can view this information 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 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

For models GS110TPv3 and GS110TPP, you can define multiple timer schedules (each with

a unique name) that you can use for PoE power delivery to attached PDs.

After you create a timer schedule, you can associate it with one or more PoE ports (see

Configure the PoE port settings on page 98). You can use a separate timer schedule for

each PoE port.

After you associate a timer schedule with a PoE port, the start date and time force the PoE

port to stop delivering power and the stop date and time enable the PoE port to start

delivering power.

You can create absolute timer schedules, which apply to specific dates and times, and you

can create recurring timer schedules. For each timer schedule, you can add multiple entries

that apply to the selected timer schedule only.

Create a PoE timer schedule

The maximum number of timer schedules that you can add is 100.

To create a PoE timer schedule:

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.

15. From the Link Trap menu, select whether or not to send a trap when the link status

changes.

By default, the switch sends a link trap.

16. 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.

the probe port.

• Probe. Use the port to monitor a mirrored port.

• Trunk Member. The port is a member of a link aggregation trunk. Look

at the LAG pages for more information.

Physical Status The port speed and duplex mode.

Link Status Indicates whether the link is up or down.

Frame Size (1522 to 10000) The maximum Ethernet frame size that each interface can support. The

frame size depends on your selection from the Frame Size menu above the

table and applies to each interface.

MAC Address The physical address of the specified interface.

PortList Bit Offset The bit offset value that corresponds to the port when the MIB object type

PortList is used to manage in SNMP

ifIndex The ifIndex of the interface table entry associated with the port.

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. By default, the LAG

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.

The switch supports eight LAGs.

Configure 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.

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

packet can either reject it or insert a tag using its default VLAN ID. A 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 64 VLANs.

The following VLANs are preconfigured on the switch and you cannot delete them:

• VLAN 1. The default VLAN of which all ports are members.

•VLAN 4088. The default Auto-VoIP VLAN. By default, this VLAN does not include any

members but you can manually add members.

• VLAN 4089. The Auto-Video VLAN. By default, this VLAN does not include any members

but you can manually add members.

Tagged VLANs The number of tagged VLANs for the interface.

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 a VLAN ID. The MAC-to-VLAN

configurations are shared across all ports of the switch (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,

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 you can configure a MAC address

mapping to a VLAN that you did not yet create on the switch.

Add a MAC-based VLAN

To add a MAC-based VLAN:

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.

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 that

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

frames that arrive 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 (see Configure the PVID

settings for an interface on page 158).

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.

Configure the 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 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 179.

The switch support the following spanning tree versions:

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

on page 181 and Configure the CST port settings on page 183.

• 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 188 and Configure and view the port settings for an MST instance on page 191.

• 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 the Rapid STP

information on page 187.

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

parameters pointtopoint and edgeport. 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.

7. Specify the CST options:

• Bridge Priority. When switches or bridges are running STP, each is assigned a

priority. After exchanging BPDUs, the switch with the lowest priority value becomes

the root bridge. Specify the bridge priority value for the Common and Internal

Spanning Tree (CST). The range is from 0 to 61440. The bridge priority is a multiple

of 4096. If you specify a priority that is not a multiple of 4096, the priority is

automatically set to the next lowest priority that is a multiple of 4096. For example, if

you set the priority to any value between 0 and 4095, the switch automatically sets the

value to 0. The default value is 32768.

• Bridge Max Age (secs). The bridge maximum age time for the Common and Internal

Spanning Tree (CST), which indicates the time in seconds a bridge must wait before

implementing a topological change. The range is from 6 to 40, and the value must be

less than or equal to (2 * Bridge Forward Delay) – 1 and greater than or equal to 2 *

(Bridge Hello Time +1). The default value is 20.

• Bridge Hello Time (secs). The bridge hello time for the Common and Internal

Spanning Tree (CST), which indicates the time in seconds a root bridge must wait

between configuration messages. The value is fixed at 2 seconds. The value must be

less than or equal to (Bridge Max Age / 2) – 1. The default hello time value is 2.

• Bridge Forward Delay (secs). The bridge forward delay time, which indicates the

time in seconds a bridge must remains in a listening and learning state before

forwarding packets. The value must be greater or equal to (Bridge Max Age / 2) + 1.

The time range is from 4 seconds to 30 seconds. The default value is 15 seconds.

• Spanning Tree Maximum Hops. The maximum number of bridge hops the

information for a particular CST instance can travel before being discarded. The

range is from 6 to 40. The default is 20 hops.

Manage IGMP snooping

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

forward IPv4 multicast traffic intelligently. Multicast IPv4 traffic is traffic 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 detected or

processed by all connected nodes. For multicast packets, this approach could lead to a less

efficient use of the network bandwidth, particularly when the packets are intended for a small

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

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

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

shared media while the multicast packets are being flooded. Such as waste of bandwidth is

even worse when the LAN segment is not shared, for example in full-duplex links.

Allowing switches to snoop IGMP packets can solve this problem. While the IGMP packets

are being forwarded throughout the network, the switch uses the information in the packets to

determine which segments must receive packets that are directed to the group address.

IGMP snooping querier overview

IGMP snooping requires that one central switch or router periodically queries 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.

Table 45. Querier VLAN Status information

Field Description

VLAN ID The VLAN ID on which IGMP snooping querier is administratively enabled and the

VLAN exists in the VLAN database.

Operational State The operational state of the IGMP snooping querier on a VLAN. It can be in any of

the following states:

• Querier. The snooping switch is the querier in the VLAN. The snooping switch

sends out periodic queries with a time interval equal to the configured querier

query interval. If the snooping switch finds a better querier in the VLAN, it

moves to non-querier mode.

• Non-Querier. The snooping switch is in non-querier mode in the VLAN. If the

querier expiry interval timer expires, the snooping switch moves into querier

mode.

• Disabled. The snooping querier is not operational on the VLAN. The snooping

querier moves to disabled mode when IGMP snooping is not operational on

the VLAN or when the querier address is not configured or the network

management address is also not configured.

Operational Version The operational IGMP protocol version of the querier.

Last Querier Address The IP address of the last querier from which a query was snooped on the VLAN.

Last Querier Version The IGMP protocol version of the last querier from which a query was snooped on

the VLAN.

Operational Max Response

Time

The maximum response time to be used in the queries that are sent by the

snooping querier.

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 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

broadcast destination address (FF:FF:FF:FF:FF:FF) 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 broadcast 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

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

8-Port Gigabit (PoE+) Ethernet Smart Managed Pro Switch with (2 SFP or 2 Copper Ports and)

Cloud Management

Configure Switching User Manual231

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.

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

For information about how to configure the routing mode and display IP routing data, see the

following sections:

•Configure the router settings on page 236

Table 51. IP Statistics information

Field Description

IpInReceives The total number of input datagrams received from interfaces, including

those received in error.

IpInHdrErrors The number of input datagrams discarded due to errors in their IP headers,

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.

8-Port Gigabit (PoE+) Ethernet Smart Managed Pro Switch with (2 SFP or 2 Copper Ports and)

Cloud Management

Configure Routing User Manual240

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.

IcmpInMsgs The total number of ICMP messages that the entity received. This counter

includes all those counted by icmpInErrors.

IcmpInErrors The number of ICMP messages that the entity received but determined as

having ICMP-specific errors (bad ICMP checksums, bad length, and so on).

IcmpInDestUnreachs The number of ICMP destination unreachable messages received.

IcmpInTimeExcds The number of ICMP time exceeded messages received.

IcmpInParmProbs The number of ICMP parameter problem messages received.

IcmpInSrcQuenchs The number of ICMP source quench messages received.

IcmpInRedirects The number of ICMP redirect messages received.

IcmpInEchos The number of ICMP echo (request) messages received.

IcmpInEchoReps The number of ICMP echo reply messages received.

IcmpInTimestamps The number of ICMP timestamp (request) messages received.

IcmpInTimestampReps The number of ICMP timestamp reply messages received.

IcmpInAddrMasks The number of ICMP address mask request messages received.

IcmpInAddrMaskReps The number of ICMP address mask reply messages received.

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.

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.

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.

IcmpOutTimestamps The number of ICMP timestamp (request) messages.

IcmpOutTimestampReps The number of ICMP timestamp reply messages sent.

IcmpOutAddrMasks The number of ICMP address mask request messages sent.

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

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.

To view entries in the ARP cache:

Configure Quality of Service User Manual260

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 different types of network traffic

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

8-Port Gigabit (PoE+) Ethernet Smart Managed Pro Switch with (2 SFP or 2 Copper Ports and)

Cloud Management

Configure Quality of Service User Manual261

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

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.

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, if 64 bytes frame size and 64 kbps shaping are configured, the expected

shaping is approximately 48 kbps.

11. In the Interface Ingress Rate Limit field, specify the maximum inbound transmission rate

bandwidth in kbps.

This setting is used to shape the inbound transmission rate in increments of 1 percent in

a range of 0–100. The interface discards traffic that arrives at a bandwidth in excess of

the specified limit.

12. Click the Apply button.

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

(internal traffic class) from 0 to 7.

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, traffic 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, besides 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.

The Other DSCP Values (Local/Experimental Use) section allows you to set non-default

values for advanced settings.

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 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.

If congestion occurs, packets might be delayed, sent sporadically, or dropped. For typical

Internet applications, such as email and file transfers, a slight degradation in service is

8-Port Gigabit (PoE+) Ethernet Smart Managed Pro Switch with (2 SFP or 2 Copper Ports and)

Cloud Management

Configure Quality of Service User Manual269

acceptable and in many cases unnoticeable. However, any degradation of service can

negatively affect applications with strict timing requirements, such as voice and 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 the DiffServ mode and display the entries in the

DiffServ private MIB tables

You can enable or disable DiffServ and display the current and maximum number of rows in

each of the main DiffServ private MIB tables.

To configure the DiffServ mode and display the entries in the DiffServ private MIB

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
