Getting Started User Manual12

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.

Note: The switch is designed for management by NETGEAR Insight:

You can use the NETGEAR Insight app on your mobile device or the

Insight Cloud portal from a web browser on your Windows-based

computer, Mac, or tablet. By default, the local browser UI

management method is disabled. However, if you use NETGEAR

Insight to manage the switch, you can still use a limited menu of the

local browser UI, mostly for switch maintenance tasks.

The switch provides management options that let you discover the switch on the network and

configure, monitor, and control the switch:

• NETGEAR Insight app. Using the NETGEAR Insight app, you can discover the switch

on the network and add the switch to the NETGEAR Insight app so that you can set up

the switch in the network and manage and monitor the switch remotely from your mobile

device.You can choose from four methods to add the switch to the NETGEAR Insight

app: You can scan your network for the switch, scan the QR code or the barcode of the

switch, or add the serial number of the switch. For information about the NETGEAR

Insight app and Insight Cloud portal, visit netgear.com/insight and

netgear.com/support/product/Insight.aspx. For knowledge base articles about

NETGEAR Insight, visit netgear.com/support.

• Insight Cloud portal. Using the NETGEAR Insight Cloud portal, you can set up the

switch in the network, perform advanced remote setup, configuration, and management,

monitor the switch, analyze the switch and network usage, and, if necessary, troubleshoot

the switch and the network. The Insight Cloud portal is available to Insight Premium and

Insight Pro subscribers. A free trial is available for new customers.

• Local browser UI. By default, the management mode of the switch is set to NETGEAR

Insight. With this setting you can manage the switch using the Insight app or the Insight

Cloud portal. For complex tasks such as integrating with an existing network of devices

that are not managed through Insight, and for debugging purposes, you can change the

management mode of the switch to Direct Connect Web-browser Interface and access

the local browser UI. In this mode, you can change the settings of the specific device, but

we recommend that you do not use this mode to change settings that are Insight

manageable because they will not be synchronized with Insight or to the network location

and other devices to which you assigned the switch.

Insight Managed 8-Port Gigabit (Hi-Power) PoE+ Smart Cloud Switch with NETGEAR FlexPoE Power

Getting Started User Manual13

Note: Changes to Insight-manageable settings from the local browser UI might

also create conflicts with the rest of the Insight-managed network to which

the device is connected. While you manage the switch with the local

browser UI, you cannot use the Insight app or Insight Cloud portal. To

reenable management of the device remotely or through the cloud, you

can return the management mode to NETGEAR Insight at any time so that

you can manage the switch with the Insight app or Insight Cloud portal.

To use the local browser UI, after you connect the switch to your network, you must

change the management method to Direct Connect Web-browser Interface (see Change

the management mode of the switch on page 32).

Manage the switch by using the local

browser UI

This manual describes how to use the local browser UI to manage and monitor the switch.

For information about using the NETGEAR Insight app and Insight Cloud portal to manage

the switch, visit netgear.com/insight and netgear.com/support/product/Insight.aspx. For

knowledge base articles about NETGEAR Insight, visit netgear.com/support.

Access the switch

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

• On-network and connected to the Internet. When you use the local browser 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 local browser UI. We refer to this setup as on-network.

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

on page 15).

• 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.

Before you can access the full menu of the local browser UI, you must connect the switch

to a network with Internet access at least once so that you can register the switch with

NETGEAR and unlock the full menu.

For more information, see the following sections:

•Register and access the switch with your NETGEAR account on page 29.

•Access the switch off-network and not connected to the Internet on page 25.

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.

•T3. Time that the server sent a reply.

•T4. 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.

8. 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.

9. 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.

10. 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.

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.

IP mask value is 0.0.0.0, access is allowed from any IP address. Otherwise, every client’s

address is ANDed with the mask, as is the management station IP address. If the values

are equal, access is allowed.

For example, if the management station IP address and management station IP mask

settings are 192.168.1.0/255.255.255.0, any client with an IP address in the range from

192.168.1.0 to 192.168.1.255 (inclusive) is allowed access. To allow access from only

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. 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 parameters that are applied to the switch.

To configure global LLDP settings:

advertisements.

• Hold Multiplier. The transmit interval multiplier value, in which the transmit hold

multiplier multiplied by the transmit interval is the time to live (TTL) value that the

switch advertises to its neighbors.

• Reinitializing Delay. The number of seconds that the switch waits before attempting

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

• T ransmit Delay. The number of seconds that the switch waits between transmissions

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

on the switch.

Configure DHCP snooping

DHCP snooping 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.

• 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.

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.

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.

To configure 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.

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

Insight Managed 8-Port Gigabit (Hi-Power) PoE+ Smart Cloud Switch with NETGEAR FlexPoE Power

Configure Switching User Manual122

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 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 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.

Manage the basic VLAN settings

You can add, change, and delete VLANs. For information about adding members to a VLAN,

Dynamic VLANs Indicates None because the switch does not support dynamic VLANs.

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).

Insight Managed 8-Port Gigabit (Hi-Power) PoE+ Smart Cloud Switch with NETGEAR FlexPoE Power

Configure Switching User Manual131

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 the user is allowed to configure a MAC

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

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.

Insight Managed 8-Port Gigabit (Hi-Power) PoE+ Smart Cloud Switch with NETGEAR FlexPoE Power

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

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.

Note: It can take up to 10 seconds for GARP configuration changes to take effect.

To configure the GARP switch settings:

Configure Spanning Tree Protocol

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

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

tree versions supported include Common STP, Multiple STP, and Rapid STP.

Spanning Tree Protocol overview

Classic STP provides a single path between end stations, avoiding and eliminating loops. For

information on configuring Common STP, see Configure the CST port Settings on

page 151.

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 (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). 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.

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.

Configure IGMP snooping

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

forward multicast traffic intelligently. Multicast IP 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.

IGMP snooping overview

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

Insight Managed 8-Port Gigabit (Hi-Power) PoE+ Smart Cloud Switch with NETGEAR FlexPoE Power

Configure Switching User Manual168

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.

In addition to building and maintaining lists of multicast group memberships, the IGMP

snooping switch also maintains a list of multicast routers. Multicast packets are forwarded on

ports to which multicast routers are connected. With IGMP snooping, only one querier can be

active in the network. All other routers in the network are suppressed and are not detectable

by the switch. If a query is not received on an interface within a specified period, the interface

is removed from the list of interfaces to which multicast routers are attached. However, by

default, the multicast router expiration time is zero, that is, the multicast router does not

expire.

A statically configured router that is connected to an interface or VLAN on the switch is

automatically added to the list with learned multicast routers. The interface must be active or

must be both active and a member of the VLAN.

Configure MLD snooping

In IPv4, Layer 2 switches can use IGMP snooping to limit the flooding of multicast traffic by

dynamically configuring Layer 2 interfaces so that multicast traffic is forwarded to only those

interfaces associated with IP multicast address. In IPv6, MLD snooping performs a similar

function. With MLD snooping, IPv6 multicast data is selectively forwarded to a list of ports

that want to receive the data, instead of being flooded to all ports in a VLAN. This list is

constructed by snooping IPv6 multicast control packets.

MLD snooping overview

Multicast Listener Discovery (MLD) is a protocol used by IPv6 multicast routers to discover

the presence of multicast listeners (nodes that must receive IPv6 multicast packets) on its

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

nodes. MLD 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.

The switch can snoop on both MLDv1 and MLDv2 protocol packets and bridge IPv6 multicast

data based on destination IPv6 Multicast MAC Addresses. The switch can be configured to

perform MLD snooping and IGMP snooping simultaneously.

Insight Managed 8-Port Gigabit (Hi-Power) PoE+ Smart Cloud Switch with NETGEAR FlexPoE Power

Configure Switching User Manual183

In addition to building and maintaining lists of multicast group memberships, the MLD

snooping switch also maintains a list of multicast routers. Multicast packets are forwarded on

ports to which multicast routers are connected. With MLD snooping, only one querier can be

active in the network. All other routers in the network are suppressed and are not detectable

by the switch. If a query is not received on an interface within a specified period, the interface

is removed from the list of interfaces to which multicast routers are attached. However, by

default, the multicast router expiration time is zero, that is, the multicast router does not

expire.

A statically configured router that is connected to an interface or VLAN on the switch is

automatically added to the list with learned multicast routers. The interface must be active or

must be both active and a member of the VLAN.

Enable MLD snooping

You can enable MLD snooping.

To enable MLD snooping:

Configure multicast VLAN registration

IGMP snooping helps to 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)

prevents the duplication of multicast traffic when multicast group member ports belong to

different VLANs.

MVR uses a dedicated multicast VLAN to forward multicast traffic over a Layer 2 network.

You can use MVR for certain types of multicast traffic, such as traffic from an IPTV

application. Clients can dynamically join or leave the multicast VLAN without interfering with

their membership in other VLANs.

Like IGMP snooping, MVR lets the switch listen to IGMP messages so that the switch can

learn about multicast group membership.

Configure the global MVR settings

IGMP group membership report before removing the port from the multicast group

membership. The time is equal to tenths of a second. The range is from 1 to 100 tenths.

The default is 5 tenths or one-half second.

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.

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.

Insight Managed 8-Port Gigabit (Hi-Power) PoE+ Smart Cloud Switch with NETGEAR FlexPoE Power

Configuring Routing User Manual209

How the switch handles routing

For each incoming packet, the switch uses the destination MAC address to determine if the

address matches a configured routing interface. If it does, the switch searches the host table

for a matching destination IP address:

• The host table contains a matching IP address.The packet is routed to the host.

• The host table does not contain a matching IP address. The switch searches for the

longest prefix match on the destination IP address:

-A match occurs. The packet is routed to the next hop.

-No match occurs but a default route exists. The packet is routed to the next hop

that is specified in the default route.

-No match occurs and no default route exists. The packet is dropped.

The routing table can include entries that were manually added. The host table can include

entries that were manually added or dynamically added through ARP.

Enable the routing mode

By default, the routing mode is disabled on the switch. You can enable the routing mode to let

the switch route traffic through its interfaces.

You can also enable routing for a VLAN interface (see Configure routing VLANs on

page 213) and use the VLAN routing wizard to create a VLAN routing interface (see

Configure VLAN routing with the VLAN Routing Wizard on page 214).

To enable routing on the switch:

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.

Field Description

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

received in error.

IpInHdrErrors The number of input datagrams discarded because of errors in 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 the 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 (for example, 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 the final IP

destination, which caused the switch to attempt to forward them to the final

destination. In entities that do not act as IP gateways, this counter includes only

those packets that were source-routed via 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 which were discarded (for example, for

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

while awaiting reassembly.

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.

Insight Managed 8-Port Gigabit (Hi-Power) PoE+ Smart Cloud Switch with NETGEAR FlexPoE Power

Configuring Routing User Manual212

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

prevent their transmission to their destination, but which were discarded (for

example, for lack of buffer space). This counter includes 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 that received fragments are held while they

are awaiting reassembly at this entity.

IpReasmReqds The number of IP fragments received that needed to be reassembled at this

entity.

IpReasmOKs The number of IP datagrams successfully reassembled.

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

because of timing out, errors, and so on). This is not necessarily a count of

discarded IP fragments because 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 successfully 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 example, because 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 that included

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.

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.

Configure routing VLANs

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

supporting routing. You can also configure the software to allow traffic on a VLAN to be

treated as if the VLAN were a router port.

When a port is enabled for bridging (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 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

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 because of

problems discovered within ICMP, such as a lack of buf fers. This value does not

include errors discovered outside the ICMP layer, such as the inability of IP to

route the resulting datagram.

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. Because hosts do not send

redirects, this counter is always zero for a host.

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.

VLAN spans multiple physical networks, or when additional segmentation or security is

required. This section shows how to configure switch software to support VLAN routing. 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.

Configure VLAN routing with the VLAN Routing Wizard

The VLAN Routing Wizard creates a VLAN routing interface, configure the IP address and

subnet mask for the interface, and add selected ports or LAGs to the VLAN. With this wizard,

you can:

•Create a VLAN.

•Add selected ports to the newly created VLAN and remove selected ports from the default

VLAN.

•Optionally, you can create a LAG, add selected ports to a LAG, then add the LAG to the

newly created VLAN.

•Enable tagging on selected ports if the port is in another VLAN. Disable tagging if a

selected port does not exist in another VLAN.

•Exclude ports not selected from the VLAN.

•Enable routing on the VLAN using the IP address and subnet mask entered.

To configure VLAN routing using the VLAN routing wizard:

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.

For information about finding the IP address of the switch, see Access the switch on

page 14.

9. In the Network Mask field, define the subnet mask of the VLAN interface.

10. In the Ports table, click each port once, twice, or three times to configure one of the following

modes or reset the port to the default settings:

• T (T agged). Select the ports on which all frames transmitted for this VLAN are tagged.

The ports that are selected are included in the VLAN.

• U (Untagged). Select the ports on which all frames transmitted for this VLAN are

untagged. The ports that are selected are included in the VLAN.

By default, the selection is blank, which means that the port is excluded from the VLAN.

11. In the LAG table, click each LAG once, twice, or three times to configure one of the following

modes or reset the LAG to the default settings:

• T (Tagged). Select the LAGs on which all frames transmitted for this VLAN are

tagged. The LAGs that are selected are included in the VLAN.

• U (Untagged). Select the LAGs on which all frames transmitted for this VLAN are

untagged. The LAGs that are selected are included in the VLAN.

By default, the selection is blank, which means that the LAG is excluded from the VLAN.

Configure ARP

The address resolution protocol (ARP) associates a layer 2 MAC address with a layer 3 IPv4

address. The switch support both dynamic and manual ARP configuration. With manual ARP

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

ARP is a required part of the Internet protocol (IP) and is used to translate an IP address to a

media (MAC) address, defined by a local area network (LAN) such as an Ethernet network.

device that must send 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 achieves this by

broadcasting an ARP request packet, to which the intended recipient responds by sending an

ARP unicast reply that contains its MAC address. Once learned, the MAC address is used in

the destination address field of the Layer 2 header prepended to the IP packet.

The ARP cache is a table maintained locally in each device on the network. ARP cache

entries are learned by examining the source information in the ARP packet payload fields,

regardless of whether it is an ARP request or response. In this way, when an ARP request is

broadcast to all stations on a LAN segment or virtual LAN (VLAN), each recipient can store

the sender’s IP address and MAC address in its ARP cache. The ARP response, which is a

unicast reply, is normally detected only by the device that sends the ARP request. That

device stores the sender’s information in its ARP cache. Newer information always replaces

existing content in the ARP cache.

If you move a device in the network, the device’s MAC address can become associated with

another IP address. Or if you reconfigure, disconnect, or power off the device, the device’ s IP

address can disappear from the network altogether. To prevent such situations from causing

information in the ARP cache to become outdated, each device on the network periodically

updates the entries in its ARP cache with new information from the network. On the switch,

you can set the ageout interval for ARP entries from 15 to 21600 seconds. When the ageout

interval is reached, ARP entries for which the switch did not receive an ARP reply are

removed form the switch ARP cache.

The switch supports 512 ARP entries, which include dynamic and static ARP entries.

•Manage Differentiated Services

Configure Quality of Service User Manual230

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 get 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 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 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

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

Insight Managed 8-Port Gigabit (Hi-Power) PoE+ Smart Cloud Switch with NETGEAR FlexPoE Power

Configure Quality of Service User Manual231

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.

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.

Configure Quality of Service User Manual239

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 it is not

guaranteed. 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.

Overview of how you can define 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.

Packet processing begins by testing the class match criteria for a packet. A policy is applied

to a packet when a class match within that policy is found.

Configure the DiffServ settings

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. 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 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.

Create and configure an IPv6 DiffServ class

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.

Consider the maximum delay time when you are configuring RADIUS maximum retransmit

and RADIUS time-out values. If multiple RADIUS servers are configured, the maximum

retransmit period on each server runs out before the next server is attempted. A retransmit

does not occur until the configured time-out period on that server passes without a response

from the RADIUS server. Therefore, the maximum delay in receiving a response from the

RADIUS application equals the retransmit time x time-out period for all configured servers. If

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

until the RADIUS application returns a 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.

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

For information about finding the IP address of the switch, see Access the switch on

page 14.

4. Enter one of the following passwords:

•After registration, enter your customized local device password.

•If you previously added the switch to an Insight network location, enter the Insight

network password.

For more information about the local device password and the Insight network password,

see Credentials for the local browser UI on page 28.

5. Click the Login button.

The System Information page displays.

6. Select Security > Management Security > RADIUS > Global Configuration.

The RADIUS Configuration page displays.

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

a RADIUS authentication server on the switch on page 267). The switch supports up to

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.

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

packet is retransmitted to the RADIUS server.

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

Consider the maximum delay time when you are configuring RADIUS maximum

retransmit and RADIUS time-out values. If multiple RADIUS servers are configured, the

maximum retransmit period on each server runs out before the next server is attempted.

A retransmit does not occur until the configured time-out period on that server passes

without a response from the RADIUS server. Therefore, the maximum delay in receiving

a response from the RADIUS application equals the retransmit time x time-out period for

all configured servers. If the RADIUS request was generated by a user login attempt, all

user interfaces are blocked until the RADIUS application returns a response.

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

retransmissions.

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