Features for Switch Model M4300-96X

For hardware information about switch model M4300-96X, including information about

supported port cards, power supply units (PSUs), and Power over Ethernet (PoE) budgets,

see the Fully Managed Stackable Switch M4300-96X Hardware Installation Guide.

This section describes the features that this release supports for switch model M4300-96X.

Slot-Based Port Numbering

All physical ports on switch model M4300-96X are based on slots. Because this model

supports 12 slots and each port card provides eight ports, the port numbering is in the format

unit number/slot number/port number.

APM408C, APM408P, and APM408F Port Cards

For the APM408C, APM408P, and APM408F port cards, the numbering is as follows:

•The unit is the number that is assigned to the switch, either automatically generated and

assigned by the system, or manually assigned. The unit range is from 1 to 8.

•The slot is one of 12 slots that this model supports. Therefore, the slot number ranges

from 1 to 12.

•Each slot can accommodate one port card, and each port card provides eight ports.

Therefore, the port range is from 1 to 8.

For example, the fifth port in the sixth slot of a switch model M4300-96X with a unit number 1

is designated as 1/6/5. Similarly, the very first port on the switch is 1/1/1 and the very last port

is 1/12/8.

APM402XL Port Card

The numbering of the ports on the APM402XL port card is different from the other port cards.

You can use a 40G port either with a break-out cable, in which case the single 40G port can

support up to four individual 10G ports, or with a connection to another single 40G port.

•Port 1 (the left 40G port on the port card) uses the following numbering:

-If connected with a break-out cable to four individual 10G ports, the port numbers are

1, 2, 3, and 4.

-If connected to another single 40G port, the port number is 1. In that situation, only

port number 1 is used and port numbers 2, 3, and 4 are not used on the port card.

•Port 2 (the right 40G port on the port card) uses the following numbering:

-If connected with a break-out cable to four individual 10G ports, the port numbers are

5, 6, 7, and 8.

-If connected to another single 40G port, the port number is 5. In that situation, only

port number 5 is used and port numbers 6, 7, and 8 are not used on the port card.

M4300 Intelligent Edge Series Fully Managed Stackable Switches

Get Started User Manual18

For example, if a switch with unit number 1 includes an APM402XL port card in slot 9, port 1

on the port card is connected to four individual port cards, and port 2 on the port card is

connected to another single 40G port, the port numbering is as follows: 1/9/1, 1/9/2, 1/9/3,

1/9/4, and 1/9/5.

By default, the 40G ports on the APM402XL port card (that is, port 1 and port 5) are active,

which means that they are in the attached state, can be detected, and you can use them. The

expandable 10G ports on the APM402XL port card (that is, ports 2–4 on the first 40G port

and ports 6–8 on the second 40G port) are nonactive, which means that they are in the

detached state and you cannot use them. However, you can configure them to be in the

attached state so that you can use them (see Configure Expandable Port Settings on

page 271).

Slot Configuration

By default, the slots of the M4300-96X are configured as empty slots, that is, as slots in which

no port cards are installed. None of the slots are preconfigured. For information about

configuring slots, see Configure and View Information About Slots and Port Cards on

page 49.

PoE Operation and Configuration

The PoE feature supports port cards in the slots of switch model M4300-96X:

•When you start switch model M4300-96 with APM408P PoE port cards already installed,

the switch initializes these port cards for PoE operation. Any existing configurations for

the slots is automatically applied. Therefore, PoE is operational immediately after the

switch completes its startup process.

•When you install one or more APM408P PoE port cards while switch model M4300-96 is

operating, the switch detects these modules, initializes them, and automatically apples

any existing configurations for the slots.

•When you remove one or more APM408P PoE port cards while switch model M4300-96

is operating, the switch detects the absence of these port cards and automatically adjusts

the configuration.

Power management enhances PoE functionality through the following features:

•Priority-based dynamic power management

•Automatic power rebalancing to meet the PoE power demand if system power is limited

•Automatic detection of insertion and removal of a power supply unit (PSU) and automatic

recalculation of the available power

PoE firmware updates occur on a slot basis (that is, for each APM408P port card).

For more information about PoE, see Configure Power over Ethernet on page 124.

Stacking

You can configure all ports on switch model M4300-96X as stacking ports. However, a limit of

a maximum of 16 active stacking links applies.

The APM402XL port card supports stacking over 40G ports only (that is, over port 1 and

port 5 only). When you expands the ports, you cannot use the 10G ports for stacking.

For more information about stacking, see Chapter 3, Manage Stacking.

Using SNMP

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 “-” 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.

SNMP is enabled by default. The System Information page, which is the page that displays

when you log in, displays the information that you need to configure an SNMP manager to

access the switch.

Any user can connect to the switch using the SNMP v3 protocol, but for authentication and

encryption, the switch supports only one user, which is admin; therefore, only one profile can

be created or modified.

Management VLAN Overview

For you to manage the device by using the web-based configuration utility, the device

management IP address must be defined and known. A management VLAN interface is

created by default and it gets an IP address if a DHCP server is present. If it fails to get an IP

address, a fallback address 169.254.100.100/255.255.0.0 is assigned to it. Management

VLAN is used as the default source interface for syslog, message log, and SNMP client, and

so on The network interface is disabled by default.

The management VLAN is the logical interface used for in-band connectivity with the switch

through any of the switch’s front panel ports. The configuration parameters associated with

the switch’s management VLAN do not affect the configuration of the front panel ports

through which traffic is switched or routed.

To access the switch over a network, you must first configure it with IP information (IP

address, subnet mask). You can configure the IP information using any of the following:

•DHCP

•Terminal interface through the EIA-232 port

After you establish in-band connectivity, you can change the IP information using any of the

following:

•Terminal interface through the EIA-232 port

•Terminal interface through Telnet

•SNMP-based management

•Web-based management

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 software operates

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

Time sources are established by stratums. Stratums 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 stratums:

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

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

time servers provide primary network time standards.

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

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

, from

a Stratum 1 server.

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

type.

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

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

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

•T

3. Time that the server sent a reply.

•T

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

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

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

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

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

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

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

device using the SNTP Server Configuration page.

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

at every poll interval.

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

SNTP servers.

To configure the SNTP server settings:

1. Launch a web browser.

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

The login window opens.

The default value is IPv4.

7. In the Address field, specify the address 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.

Two SNTP servers exist by default:

•time-a.netgear.com

•time-c.netgear.com

8. Enter a Port number on the SNTP server to which SNTP requests are sent.

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

9. Specify the Priority of this server entry in determining the sequence of servers to which

SNTP requests are sent.

The client continues sending 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. A server entry with a precedence of 1 is queried before a server with a

priority of 2, and so forth. If more than one server has the same priority, then the

Manage Precision Time Protocol

Precision Time Protocol (PTP, IEEE 1588) is a protocol that enables precise synchronization

of clocks with a sub-microsecond accuracy across a packet-based network. PTP lets network

devices of different precision and resolution synchronize to a grandmaster clock through an

exchange of packets across the network. The switch supports a PTP end-to-end transparent

clock, which is enabled by default, both globally and at the port level.

Note: The switch itself is not affected by PTP.

Management Template Preference

A Switch Database Management (SDM) template is a description of the maximum resources

a switch or router can use for various features. Different SDM templates allow different

combinations of scaling factors, enabling different allocations of resources depending on how

the device is used. In other words, SDM templates enable you to reallocate system

resources to support a different mix of features based on your network requirements.

Note: If you attach a unit to a stack and its template does not match the

stack’s template, then the new unit automatically reboots using the

template used by the other stacking members. To avoid the automatic

reboot, first set the template to the SDM template used by existing

members of the stack. Then power off the new unit, attach it to the

stack, and power it on.

You can configure SDM template preferences for the switch.

Configure LLDP

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

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

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

the LAN.

LLDP is a one-way protocol; there are no 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/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:

•Auto-discovery 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).

M4300 Series Switch Stacking Overview

A stackable switch is a switch that is fully functional operating as a stand-alone unit but can

also be set-up to operate together with up to seven other switches. This group of switches

shows the characteristics of a single switch while having the port capacity of the sum of the

combined switches.

One of the switches in the stack controls the operation of the stack. This switch is called the

stack master. The remaining switches in the stack are stack members. The stack members

use stacking technology to behave and work together as a unified system. Layer 2 and higher

protocols present the entire switch stack as a single entity to the network.

The stack master is the single point of stack-wide management. From the stack master, you

configure the following:

•System-level (global) features that apply to all stack members

•Interface-level features for all interfaces on any stack member

A switch stack is identified in the network by its network IP address. The network IP address

is assigned according to the MAC address of the stack master. Every stack member is

uniquely identified by its own stack member number, which is from 1 to 8. The stack master

can be any number within that range.

Stacking supports the following:

•Up to eight switches per stack

•Single IP address management through a web browser, the CLI, or SNMP

•Master-slave configuration:

•The master retains configuration for entire stack.

•Automatic detection of new members, with synchronization of firmware (upgrade or

downgrade as needed).

•Configuration updates across the stack through a single operation.

•Automatic master failover. Fully resilient stack with chain and ring topology.

•Hot swapping (insertion and removal) of stack members.

Firmware Synchronization and Upgrade

All stack members must run the same software version to ensure compatibility within the

stack. By default, if a unit is added to the stack and its software version is not the same as the

stack master, that unit is not allowed to join the stack. You can enable the Stack Firmware

Auto Upgrade feature, which automatically synchronizes the firmware version on the new unit

with the version running on the stack master. The synchronization operation might result in

either upgrade or downgrade of firmware on the mismatched stack member.

M4300 Intelligent Edge Series Fully Managed Stackable Switches

Manage Stacking User Manual167

Upgrading the firmware on a stack of switches is the same as upgrading the firmware on a

single switch. After you download a new image by using the File Download page or SCC, the

downloaded image is distributed to all the connected units of the stack.

Note: We recommend that you set the active image for all stack members

the same as the active image of the stack master. In other words, if

image1 is the active image on the stack master, all units must use

image1 as the active image. For information about configuring the

active image, see Configure Dual Image Settings on page 681.

Stack Configuration Maintenance

The stack master stores and maintains the saved and running configuration files for the

switch stack. The configuration files include the system-level settings for the switch stack and

the interface-level settings for all stack members. Each stack member retains a copy of the

saved file for backup purposes. If the master is removed from the stack or becomes

unavailable, another member is elected master and then runs from that saved configuration.

The switch master copies its running configuration to the stack member configured as the

standby unit whenever it changes (subject to some restrictions to reduce overhead). This

enables the standby unit to take over the stack operation with minimal interruption if the stack

master becomes unavailable. The running-config synchronization also occurs when the

running configuration is auto-saved on the stack master or when the standby unit changes.

Stack Master Election

All stack members are eligible stack masters. If the stack master becomes unavailable, the

remaining stack members participate in electing a new stack master from among themselves.

The following factors determine which switch is elected the stack master:

•The switch that is master always has priority to retain the role of master.

•Assigned priority.

•MAC address.

When the stack is powered up and completes the boot process or the original stack master

becomes unavailable, the stack master is determined through an election process.

The rules for stack master election are as follows:

•If a unit was elected stack master previously, then it remains the stack master and other

units are stack members.

•If no units were stack masters, or more than one unit was a stack master, then the unit

with the highest management preference is elected stack master. The management

M4300 Intelligent Edge Series Fully Managed Stackable Switches

Manage Stacking User Manual168

preference can be assigned by the administrator. However, if all units are assigned the

same management preference, then the unit with the highest MAC address is assigned

as the stack master.

Stack Factory Defaults Reset Behavior

If the stack master is reset to the factory default settings (see Reset the Switch to Its Factory

Default Settings on page 669), the stack master applies the default settings to all the stack

members and resets the stack, including all participating stack members. When the stack

boots, the stack master election process begins.

A switch can be described in terms of three semi-independent functions called the forwarding

plane, the control plane, and the management plane. The forwarding plane forwards data

packets. The forwarding plane is implemented in hardware. The control plane is the set of

protocols that determine how the forwarding plane forwards packets, deciding which data

packets are allowed to be forwarded and where they go. Application software on the

management unit acts as the control plane. The management plane is application software

running on the management unit that provides interfaces allowing a network administrator to

configure and monitor the device.

Stack NSF

Nonstop forwarding (NSF) allows the forwarding plane of stack units to continue to forward

packets while the control and management planes restart as a result of a power failure,

hardware failure, or software fault on the management unit. A nonstop forwarding failover can

also be manually initiated by clicking the Initiate Failover button on the NSF Summary page.

Traffic flows that enter and exit the stack through physical ports on a unit other than the

management continue with at most sub-second interruption when the management unit fails.

To prepare the backup management unit in case of a failover, applications on the

management unit continuously checkpoint some state information to the backup unit.

Changes to the running configuration are automatically copied to the backup unit. MAC

addresses stay the same across a nonstop forwarding failover so that neighbors are not

required to relearn them.

When a nonstop forwarding failover occurs, the control plane on the backup unit starts from a

partially initialized state and applies the checkpointed state information. While the control

plane is initializing, the stack cannot react to external changes, such as network topology

changes. Once the control plane is fully operational on the new management unit, the control

plane ensures that the hardware state is updated as necessary. Control plane failover time

depends on the size of the stack, the complexity of the configuration, and the speed of the

CPU.

The management plane restarts when a failover occurs. Management connections must be

reestablished.

M4300 Intelligent Edge Series Fully Managed Stackable Switches

Manage Stacking User Manual169

For NSF to be effective, adjacent networking devices must not reroute traffic around the

restarting device. The switch uses three techniques to prevent traffic from being rerouted:

•A protocol can distribute a part of its control plane to stack units so that the protocol can

give the appearance that it is still functional during the restart. Spanning tree and port

channels use this technique.

•A protocol can enlist the cooperation of its neighbors through a technique known as

graceful restart. OSPF uses graceful restart if it is enabled.

•A protocol can restart after the failover if neighbors react slowly enough that they cannot

normally detect the outage. The IP multicast routing protocols are a good example of this

behavior.

To take full advantage of nonstop forwarding, Layer 2 connections to neighbors must be

through port channels that span two or more stack units, and Layer 3 routes must be ECMP

routes with next hops through physical ports on two or more units. The hardware can quickly

move traffic flows from port channel members or ECMP paths on a failed unit to a surviving

unit.

Configure a Stack

You can move the primary management unit functionality from one unit to another. Upon

execution, the entire stack (including all interfaces in the stack) is unconfigured and

reconfigured with the configuration on the new primary management unit. After the reload is

complete, all stack management capability must be performed on the new primary

management unit. To preserve the current configuration across a stack move, save the

current configuration to the NVRAM before performing the stack move. A stack move causes

all routes and Layer 2 addresses to be lost. The administrator is prompted to confirm the

management move.

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 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. Each switch in the

M4300 Series and M4300-96X family supports up to 1024 VLANs. VLAN 1 is created by

default and is the default VLAN of which all ports are members.

Configure Basic VLAN Settings

The internal VLAN is reserved by a port-based routing interface and invisible to the end user.

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, there is a system-wide

table 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 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.

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

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

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

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

Configuration page.

You define a protocol-based VLAN by creating a group. Each group has 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 Switching Information User Manual209

Configure iSCSI Settings

The Internet Small Computer System Interface (iSCSI) feature helps network administrators

track iSCSI traffic between iSCSI initiators and target systems. This is accomplished by

monitoring or snooping traffic to detect packets used by iSCSI stations in establishing iSCSI

sessions and connections. Data from these exchanges is used to create classification rules

that assign the traffic between the stations to a configured traffic class. Packets in the flow

are queued and scheduled for egress on the destination port based on these rules.

In networks containing iSCSI initiators and targets, iSCSI helps to monitor iSCSI sessions or

give iSCSI traffic preferential Quality of Service (QoS) treatment. Dynamically-generated

classifier rules are used to direct the iSCSI data traffic to queues that can be given the

desired preference characteristics over other data traveling through the switch. This might

help to avoid session interruptions during times of congestion that would otherwise cause

iSCSI packets to be dropped. However, in systems where a large proportion of traffic is

iSCSI, it might also interfere with other network control-plane traffic, such as ARP or LACP.

The preferential treatment of iSCSI traffic must be balanced against the needs of other critical

data in the network.

You can view and manage iSCSI Optimization settings on the device. iSCSI Optimization

provides a means of giving traffic between iSCSI initiator and target systems special Quality

of Service (QoS) treatment.

In addition, if configured, the packets can be updated with IEEE 802.1 or IP-DSCP values.

This is done by enabling Remark. Remarking packets with priority data provides special QoS

treatment as the packets continue through the network.

6. In the iSCSI Status field, select Enable or Disable.

This globally enables or disables the iSCSI Optimization feature. By default, iSCSI

Optimization is disabled.

7. Select the QoS Profile VLAN Priority Tag or DSCP radio button.

This specifies the Quality of Service (QoS) profile that is applied to iSCSI flows. By

default, iSCSI flows are assigned to the highest VLAN Priority tag (VPT)/DSCP mapped

to the highest queue not used for switch management or voice VLAN.

Setting the VLAN Priority tag/DSCP sets the QoS profile which determines the egress

queue to which the frame is mapped. The switch default setting for egress queues

scheduling is Weighted Round Robin (WRR). Complete the QoS setting by configuring

the relevant ports to work in other scheduling and queue management modes through the

Class of Service settings. Depending on the platform, these choices might include strict

priority for the queue used for iSCSI traffic. The downside of strict priority is that, in certain

circumstances (under heavy high priority traffic), other lower priority traffic might get

starved. In WRR, the queue to which the flow is assigned to can be set to get the required

percentage.

8. Configure the global traffic class mapping in Class of Service.

The global traffic class mapping configuration determines the traffic class used to transmit

iSCSI packets. The traffic mapping configuration options are as follows:

•IEEE 802.1P

•IP-DSCP

The configuration of the CoS component determines changes in the mapping of IEEE

802.1p or IP-DSCP values to traffic classes. For more information, see Manage Class of

Service on page 468.

9. If you are using VLAN Priority as the QoS profile, in the VLAN Priority Tag field, select the

iSCSI session packets.

The range is 0 to 7. The default is 5.

10. If you are using DSCP as the QoS profile, in the DSCP list, select a value to assign iSCSI

session packets.

M4300 Intelligent Edge Series Fully Managed Stackable Switches

Configure Switching Information User Manual211

The range is 0 to 63. The default is 46.

11. Select the Remark Enable or Disable radio button.

This enables or disables the marking of iSCSI frames with the configured VLAN Priority

tag/DSCP when egressing the switch. Enabling remarks updates the packets with IEEE

802.1p or IP-DSCP values. Remarking packets with priority data provides special QoS

treatment as the packets continue through the network. Remark is enabled by default.

12. In the iSCSI Aging Time field, set the number of minutes a session can be inactive prior to

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.

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

information on configuring Common STP, see Configure CST Port Settings on page 222.

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 Forwarding). The difference between the RSTP and the traditional

STP (IEEE 802.1D) is the ability to configure and recognize full-duplex connectivity and ports

which are connected to end stations, resulting in rapid transitioning of the port to Forwarding

state and the suppression of Topology Change Notification. These features are represented

by the parameters pointtopoint and edgeport. MSTP is compatible to both RSTP and STP. It

behaves appropriately to STP and RSTP bridges. A MSTP bridge can be configured to

behave entirely as a RSTP bridge or a STP bridge.

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

802.1s and their configuration name, digest key, and revision level

must match. For additional information about regions and their effect

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

6. Specify values for CST in the appropriate fields:

• 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. Specifies the bridge priority value for the Common and Internal

Spanning Tree (CST). The valid range is 0–61440. 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 the priority is

attempted to be set to any value between 0 and 4095, it is set to 0. The default priority

is 32768.

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

Spanning Tree (CST), which indicates the amount of time in seconds a bridge waits

before implementing a topological change. The valid range is 6–40, 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 amount of time in seconds a root bridge

waits 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

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

amount of time in seconds a bridge 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.

Configure CST Port Settings

You can configure the Common Spanning Tree (CST) and Internal Spanning Tree on a

specific port on the switch.

A port can become Diagnostically Disabled (D-Disable) when DOT1S experiences a severe

error condition. The most common cause is when the DOT1S software experiences BPDU

flooding. The flooding criteria is such that DOT1S receives more than 15 BPDUs in a

3-second interval. The other causes for DOT1S D-Disable are extremely rare.

Manage IGMP Snooping

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

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

to a host group. Host groups are identified by class D IP addresses, 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 into each of the remaining network segments in accordance with the

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

connected to the network.

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

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

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

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

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

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

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

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

full-duplex links.

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

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

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

IGMP Snooping Querier Overview

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

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

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

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

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

the port where the end device is located.

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

separately, on VLANs.

Manage 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 management VLAN.

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.

Static LAGs are supported. When a port is added to a LAG as a static member, it neither

transmits nor receives LACPDUs.

Manage the Multiple Registration Protocol

Settings

Like 802.1AS, Multiple Registration Protocol (MRP) is an audio video bridging (AVB) feature

that is available on some FASTPATH platforms. MVR is a base registration protocol that

enables devices running an MRP application to register attributes to other devices in a

network. MRP provides an application to register attributes such as bandwidth for a given AV

stream and MAC address information. It is used by various applications to propagate the

registration. Blade switches support the following MRP applications:

• Multiple MAC Registration Protocol (MMRP). MMRP allows for the propagation MAC

address information in the network, and allows for the registration and deregistration of

both individual MAC address information and group MAC address membership. End

stations can request to join or leave a multicast group, or to register an individual MAC

address with a specific VLAN. MAC address entries can be dynamically registered and

deregistered if MMRP is administratively enabled on the switch.

• Multiple VLAN Registration Protocol (MVRP). MVRP registers VLANs in the network,

enabling automatic VLAN configuration on the switch. In a typical network, VLAN tagging

is common. Many nodes require ingress traffic to be tagged with a specific VLAN ID, and

other nodes require egress traffic to be transmitted with a specific VLAN ID. With the use

of MVRP on both ingress and egress, no manual VLAN configuration is required to pass

tagged traffic through the network.

Note: MRP framework must be available and enabled in all intermediate

devices to ensure that the propagation of the attributes occurs

throughout the network.

With MRP, network attributes are declared, registered, withdrawn, and removed

completely dynamically without any user intervention. This dynamic nature is especially

useful in networks where the following is true:

-Network attributes are likely to change frequently, requiring reconfiguration of the

intermediate devices.

M4300 Intelligent Edge Series Fully Managed Stackable Switches

Configure Switching Information User Manual280

-Recipients of these attributes frequently increase or decrease in number.

-Each of these changes without a dynamic self-adjusting framework would require

constant attention from the network administrator.

Manage Loop Protection

Loop protection can detect physical and logical loops between Ethernet ports on a device.

About 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 protocol data unit (PDU) packets to

a Layer 2 multicast destination address (09:00:09:09:13:A6) on all ports for which the feature

is enabled. You can selectively disable PDU packet transmission for loop protection on

specific ports even while port loop protection is enabled. If the switch receives a packet with

the previously mentioned multicast destination address, the source MAC address in the

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

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

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

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

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

•The port is shut down.

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

sent to the syslog server.)

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

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

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

switches. Loop protection is designed for unmanaged switches that drop spanning tree

bridge protocol data units (BPDUs).

You need to enable the feature globally before you can enable it at the port level so that the

system policy filter can be installed.

Loop Protection and PDU Packet Transmission

Loop protection sends loop protocol packets from all ports on which it is enabled. You can

configure the interval (1 to 5 seconds) between two successive loop protection PDU packets.

The default interval is 5 seconds. If the switch receives a loop protocol packet on a port for

which the action is set to shut down the port, the port can no longer receive and send frames.

Loop protection operates at a port level, regardless of VLAN assignment and membership,

detecting loops across VLANs.

M4300 Intelligent Edge Series Fully Managed Stackable Switches

Configure Switching Information User Manual287

Loop Protection and Spanning Tree Protocol

Loop protection does not impact end nodes and is not intended for ports that serve as uplinks

between spanning tree–aware switches. Loop protection can coexist with Spanning Tree

Protocol (STP). You can enable both loop protection and STP on a port because these

features function independently of each other. STP does not bring a port down when a loop is

detected but keeps the port in blocking state. Because PDUs are allowed in a blocking state,

loop protection packets are received and loop protection brings down the port that is involved

in the loop (if the configured action is to shut down the port).

Configure the Global Loop Protection Settings

Before you can configure loop protection for individual ports (see Configure the Loop

Protection Settings for Ports and View the Loop Protection State on page 288), you must

Specify Route Preferences

You can configure the default preference for each protocol, for example, 60 for static routes,

120 for RIP. These values are arbitrary values in the range of 1 to 255 and are independent of

route metrics. Most routing protocols use a route metric to determine the shortest path known

to the protocol, independent of any other protocol.

The best route to a destination is chosen by selecting the route with the lowest preference

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

determine the preferred route. If there is still a tie, the route with the best route metric is

chosen. To avoid problems with mismatched metrics (such as RIP and Open Shortest Path

First [OSPF] metrics, which are not directly comparable) you must configure different

preference values for each of the protocols.

Table 105. IP Basic Statistics

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.

M4300 Intelligent Edge Series Fully Managed Stackable Switches

Manage Routing User Manual301

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

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

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

gateways, this counter includes only those packets that were

source-routed through this entity, and the source-route option

processing was successful.

IpInUnknownProtos The number of locally addressed datagrams received successfully but

discarded because of an unknown or unsupported protocol.

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

encountered to prevent their continued processing, but that were

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

datagrams discarded while awaiting re-assembly.

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

protocols (including ICMP).

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

ICMP) supplied to IP in requests for transmission. This counter does

not include any datagrams counted in ipForwDatagrams.

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

encountered to prevent their transmission to their destination, but that

were discarded for reasons such as lack of buffer space. This counter

would include datagrams counted in ipForwDatagrams if any such

packets met this (discretionary) discard criterion.

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

found to transmit them to their destination. This counter includes any

packets counted in ipForwDatagrams that meet this no-route criterion.

This includes any datagrams that a host cannot route because all of its

default gateways are down.

IpReasmTimeout The maximum number of seconds for which received fragments are

held while they are awaiting reassembly at this entity.

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

entity.

IpReasmOKs The number of IP datagrams successfully re-assembled.

IpReasmFails The number of failures detected by the IP re-assembly 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.

Table 105. IP Basic Statistics (continued)

Field Description

IpRoutingDiscards The number of routing entries that were discarded even though they

were valid. One possible reason for discarding such an entry could be

to free up buffer space for other routing entries.

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 rimestamp 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.

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.

You can configure routing parameters for the switch as opposed to an interface.

To configure routing parameters for the switch:

1. Launch a web browser.

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

The login window opens.

3. Enter the user name and password.

The default admin user name is admin and the default admin password is blank, that is,

do not enter a password.

4. Click the Login button.

The System Information page displays.

5. Select Routing> IP > Advanced > IP Configuration.

6. Use Routing Mode to select Enable or Disable.

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.

Table 105. IP Basic Statistics (continued)

Field Description

M4300 Intelligent Edge Series Fully Managed Stackable Switches

Manage Routing User Manual304

You must enable routing for the switch before you can route through any of the interfaces.

The default value is Disable.

7. Use ICMP Echo Replies to select Enable or Disable.

If you select Enable, then only the router can send ECHO replies. By default ICMP echo

replies are sent for echo requests.

8. Use ICMP Redirects to select Enable or Disable.

If it is enabled globally and on interface level then only the router can send ICMP

redirects.

9. Use ICMP Rate Limit Interval to control the ICMP error packets by specifying the number

of ICMP error packets that are allowed per burst interval.

By default, the rate limit is 100 packets/sec, (the burst interval is 1000 msec). To disable

ICMP Ratelimiting set this field to 0. The valid rate interval is in the range 0 to

2147483647.

10. Use ICMP Rate Limit Burst Size to control the ICMP error packets by specifying the

number of ICMP error packets that are allowed per burst interval.

By default, the burst size is 100 packets. When the burst interval is 0, then configuring

this field is not a valid operation. The valid burst size is 1 to 200.

11. Use Select to Configure Global Default Gateway to edit the Global Default Gateway field.

12. Use Global Default Gateway to set the global default gateway to the manually configured

value.

A default gateway configured with this command is more preferred than a default

gateway learned from a DHCP server. Only one default gateway can be configured. If you

invoke this command multiple times, each command replaces the previous value.
