1. About the NETGEAR Managed

Switch Software

The purpose of the NETGEAR managed switch software is twofold:

• Assist attached hardware in switching frames, based on Layer 2, 3, or 4 information

contained in the frames.

• Provide a complete device management portfolio to the network administrator.

This chapter contains the following sections:

• Scope

• Product Concept

Note: For more information about the topics covered in this manual, visit the

support website at netgear.com/support.

Note: Firmware updates with new features and bug fixes are made

available from time to time at downloadcenter.netgear.com. Some products can regularly check the site and download new firmware, or you can check for and download new firmware manually. If the features or behavior of your product does not match what is described in this guide, you might need to update your firmware.

M4200 and M4300 Series ProSAFE Managed Switches

Scope

The NETGEAR managed switch software encompasses both hardware and software support. The software is partitioned to run in the following processors:

• CPU. This code runs the networking device management portfolio and controls the

overall networking device hardware. It also assists in frame forwarding, as needed and specified. This code is designed to run on multiple platforms with minimal changes from platform to platform.

• Networking device processor. This code does the majority of the packet switching,

usually at wire speed. This code is platform dependent, and substantial changes might exist across products.

Product Concept

Fast Ethernet and Gigabit Ethernet switching continues to evolve from high-end backbone applications to desktop switching applications. The price of the technology continues to decline, while performance and feature sets continue to improve. Devices that are capable of switching Layers 2, 3, and 4 are increasingly in demand. The NETGEAR managed switch software provides a flexible solution to these ever-increasing needs.

The exact functionality provided by each networking device on which the NETGEAR managed switch software runs varies depending upon the platform.

The NETGEAR managed switch software includes a set of comprehensive management functions for managing both the software and the network. You can manage the NETGEAR managed switch software by using one of the following three methods:

• Command-line interface (CLI)

• Simple Network Management Protocol (SNMP)

• Web-based

About the NETGEAR Managed Switch Software

2. Using the Command-Line Interface

The command-line interface (CLI) is a text-based way to manage and monitor the system. You

can access the CLI by using a direct serial connection or by using a remote logical connection with telnet or SSH.

This chapter describes the CLI syntax, conventions, and modes. It contains the following

sections:

• Command Syntax

• Command Conventions

• Common Parameter Values

• unit/slot/port Naming Convention

• Using the No Form of a Command

• Executing Show Commands

• CLI Output Filtering

M4200 and M4300 Series ProSAFE Managed Switches

Command Syntax

A command is one or more words that might be followed by one or more parameters. Parameters can be required or optional values.

Some commands, such as show network and clear vlan, do not require parameters. Other commands, such as network parms, require that you supply a value after the command. You must type the parameter values in a specific order, and optional parameters follow required parameters. The following example describes the network parms command syntax:

Format network parms ipaddr netmask [gateway]

• network parms is the command name.

• ipaddr and netmask are parameters and represent required values that you must enter

after you type the command keywords.

• [gateway] is an optional keyword, so you are not required to enter a value in place of

the keyword.

This command line reference manual lists each command by the command name and provides a brief description of the command. Each command reference also contains the following information:

• Format shows the command keywords and the required and optional parameters.

• Mode identifies the command mode you must be in to access the command.

• Default shows the default value, if any, of a configurable setting on the device.

The show commands also contain a description of the information that the command shows.

Command Conventions

The parameters for a command might include mandatory values, optional values, or keyword choices. Parameters are order-dependent. The following table describes the conventions this document uses to distinguish between value types.

Table 1. Parameter Conventions

Symbol Example Description

italic font value or [value] Indicates a variable value. You must replace the

italicized text, which can be placed within curly brackets or square brackets, with an appropriate value, which might be a name or number.

[ ] square brackets [keyword] Indicates an optional parameter. { } curly braces {choice1 | choice2} Indicates that you must select a parameter from the

list of choices.

Using the Command-Line Interface

M4200 and M4300 Series ProSAFE Managed Switches

Table 1. Parameter Conventions (continued)

Symbol Example Description

| Vertical bars choice1 | choice2 Separates the mutually exclusive choices.

[{ }] Braces within square brackets

[{choice1 | choice2}] Indicates a choice within an optional element. This

format is used mainly for complicated commands

Common Parameter Values

Parameter values might be names (strings) or numbers. To use spaces as part of a name parameter, enclose the name value in double quotes. For example, the expression “System Name with Spaces” forces the system to accept the spaces. Empty strings (““) are not valid user-defined strings. The following table describes common parameter values and value formatting.

Table 2. Parameter Descriptions

Parameter Description

ipaddr This parameter is a valid IPv4 address. You can enter the IP address in the

following formats:

• a (32 bits)

• a.b (8.24 bits)

• a.b.c (8.8.16 bits)

• a.b.c.d (8.8.8.8)

In addition to these formats, the CLI accepts decimal, hexadecimal and octal formats through the following input formats (where n is any valid hexadecimal, octal or decimal number):

• 0xn (CLI assumes hexadecimal format.)

• 0n (CLI assumes octal format with leading zeros.)

• n (CLI assumes decimal format.)

ipv6-addr This parameter is a valid IPv6 address. You can enter the IP address in the

following formats:

• FE80:0000:0000:0000:020F:24FF:FEBF:DBCB

• FE80:0:0:0:20F:24FF:FEBF:DBCB

• FE80::20F24FF:FEBF:DBCB

• FE80:0:0:0:20F:24FF:128:141:49:32

For additional information, refer to RFC 3513.

Interface or

unit/slot/port

Logical Interface Represents a logical slot and port number. This is applicable in the case of a

port-channel (LAG). You can use the logical unit/slot/port to configure the port-channel.

Name with Spaces”. An empty string (“”) is not valid.

Using the Command-Line Interface

M4200 and M4300 Series ProSAFE Managed Switches

unit/slot/port Naming Convention

The switch references physical entities such as cards and ports by using a unit/slot/port naming convention. The switch also uses this convention to identify certain logical entities, such as port channel interfaces.

The slot number has two uses. In the case of physical ports, it identifies the card containing the ports. In the case of logical and CPU ports it also identifies the type of interface or port.

Table 3. Type of Slots

Slot Type Description

Physical slot numbers Physical slot numbers begin with zero, and are allocated up to the maximum

number of physical slots.

Logical slot numbers Logical slots immediately follow physical slots and identify port-channel

(LAG) or router interfaces. The value of logical slot numbers depend on the type of logical interface and can vary from platform to platform.

CPU slot numbers The CPU slots immediately follow the logical slots.

The port identifies the specific physical port or logical interface being managed on a given slot.

Table 4. Type of Ports

Port Type Description

Physical Ports The physical ports for each slot are numbered sequentially starting from one.

For example, port 1 on slot 0 (an internal port) for a switch is 1/0/1, port 2 is 1/0/2, port 3 is 1/0/3, and so on.

Logical Interfaces Port-channel or Link Aggregation Group (LAG) interfaces are logical

interfaces that are only used for bridging functions. VLAN routing interfaces are only used for routing functions. Loopback interfaces are logical interfaces that are always up. Tunnel interfaces are logical point-to-point links that carry encapsulated

packets.

CPU ports CPU ports are handled by the driver as one or more physical entities located

on physical slots.

Note: In the CLI, loopback and tunnel interfaces do not use the

unit/slot/port format. To specify a loopback interface, you use the loopback ID. To specify a tunnel interface, you use the tunnel ID.

Using the Command-Line Interface

M4200 and M4300 Series ProSAFE Managed Switches

Using the No Form of a Command

The no keyword is a specific form of an existing command and does not represent a new or distinct command. Almost every configuration command has a no form. In general, use the no form to reverse the action of a command or reset a value back to the default. For example, the no shutdown configuration command reverses the shutdown of an interface. Use the command without the keyword no to reenable a disabled feature or to enable a feature that is disabled by default. Only the configuration commands are available in the no form.

Executing Show Commands

All show commands can be issued from any configuration mode (Global Configuration,

Interface Configuration, VLAN Configuration, etc.). The show commands provide information about system and feature-specific configuration, status, and statistics. Previously, show commands could be issued only in User EXEC or Privileged EXEC modes.

CLI Output Filtering

Many CLI show commands include considerable content to display to the user. This can make output confusing and cumbersome to parse through to find the information of desired importance. The CLI Output Filtering feature allows the user, when executing CLI show display commands, to optionally specify arguments to filter the CLI output to display only desired information. The result is to simplify the display and make it easier for the user to find the information the user is interested in.

The main functions of the CLI Output Filtering feature are:

• Pagination Control

- Supports enabling/disabling paginated output for all show CLI commands. When

disabled, output is displayed in its entirety. When enabled, output is displayed page-by-page such that content does not scroll off the terminal screen until the user presses a key to continue. --More-- or (q)uit is displayed at the end of each page.

- When pagination is enabled, press the return key to advance a single line, press q or

Q to stop pagination, or press any other key to advance a whole page. These keys are not configurable.

Note: Although some NETGEAR Managed Switch show commands already

support pagination, the implementation is unique per command and not generic to all commands.

• Output Filtering

- “Grep”-like control for modifying the displayed output to only show the user-desired

content.

- Filter displayed output to only include lines containing a specified string match.

Using the Command-Line Interface

M4200 and M4300 Series ProSAFE Managed Switches

- Filter displayed output to exclude lines containing a specified string match.

- Filter displayed output to only include lines including and following a specified string

match.

- Filter displayed output to only include a specified section of the content (for example,

“interface 0/1”) with a configurable end-of-section delimiter.

- String matching should be case insensitive.

- Pagination, when enabled, also applies to filtered output.

The following shows an example of the extensions made to the CLI show commands for the Output Filtering feature.

(NETGEAR Switch) #show running-config ? <cr> Press enter to execute the command. | Output filter options. <scriptname> Script file name for writing active configuration. all Show all the running configuration on the switch. interface Display the running configuration for specificed interface

on the switch.

(NETGEAR Switch) #show running-config | ? begin Begin with the line that matches exclude Exclude lines that matches include Include lines that matches section Display portion of lines

For new commands for the feature, see CLI Output Filtering Commands on page 184.

Using the Command-Line Interface

3. Software Modules

NETGEAR managed switch software consists of flexible modules that can be applied in various combinations to develop advanced Layer 2/3/4+ products. The commands and command modes available on your switch depend on the installed modules. Additionally, for some show commands, the output fields might change based on the modules included in the NETGEAR managed switch software.

The NETGEAR managed switch software suite includes the following modules:

• Switching (Layer 2)

• Routing (Layer 3)

• IPv6 routing

• Multicast

• Quality of Service

• Management (CLI, Web UI, and SNMP)

• IPv6 Management

Allows management of the switch through an IPv6 address without requiring the IPv6 Routing package in the system. The management address can be associated with the network port (front-panel switch ports), a routine interface (port or VLAN) and the Service port.

• Secure Management

M4200 and M4300 Series ProSAFE Managed Switches

Command Modes

The CLI groups commands into modes according to the command function. Each of the command modes supports specific commands. The commands in one mode are not available until you switch to that particular mode, with the exception of the User EXEC mode commands. You can execute the User EXEC mode commands in the Privileged EXEC mode.

The command prompt changes in each command mode to help you identify the current mode. The following table describes the command modes and the prompts visible in that mode.

Note: The command modes available on your switch depend on the software

modules that are installed. For example, a switch that does not support BGPv4 does not have the BGPv4 Router Command Mode.

Software Modules

M4200 and M4300 Series ProSAFE Managed Switches

Access the CLI

You can access the CLI by using a direct console connection or by using a telnet or SSH connection from a remote management host.

For the initial connection, you must use a direct connection to the console port. You cannot access the system remotely until the system has an IP address, subnet mask, and default gateway. You can set the network configuration information manually, or you can configure the system to accept these settings from a BootP or DHCP server on your network. For more information, see Management Interface Commands on page 56.

4. Stacking Commands

This chapter describes the stacking commands.

Note: Stacking commands are supported on the M4300 series switches only.

This chapter contains the following sections:

• Dedicated Port Stacking Commands

• Stack Port Commands

• Stack Firmware Synchronization Commands

• Nonstop Forwarding Commands for Stack Configuration

The commands in this chapter are in two functional groups:

• Show commands. Display switch settings, statistics, and other information.

• Configuration commands. Configure features and options of the switch. For every

configuration command, there is a show command that displays the configuration setting.

Note: The Primary Management Unit is the unit that controls the stack.

Dedicated Port Stacking Commands

This section describes the commands you use to configure dedicated port stacking.

stack

Use this command to set the mode to Stack Global Config.

Default None Format stack Mode Global Config

member (Stack Global Config)

Use this command to add a switch to a stack. The unit is the switch identifier of the switch to be added to the stack. The switchindex is the index into the database of the supported switch types, indicating the type of the switch being preconfigured. The switchindex is a 32-bit integer. You issue this command on the Primary Management Unit.

Default None Format member unit switchindex Mode Stack Global Config

Note: You can obtain the switch index by issuing the show supported

switchtype command in User EXEC mode.

no member

Use this command to remove a switch from a stack. The unit is the switch identifier of the switch to be removed from the stack. You issue this command on the Primary Management Unit.

Format no member unit Mode Stack Global Config

switch priority

Use this command to configure the ability of a switch to become the Primary Management Unit. The unit is the switch identifier. The value is the preference parameter that lets you specify the priority of one backup switch over another. The range for priority is 1 to 15. The switch with the highest priority value becomes the Primary Management Unit if the active Primary Management Unit fails. The switch priority defaults to the hardware management

Stacking Commands

M4200 and M4300 Series ProSAFE Managed Switches

preference value 1. Switches without the hardware capability to become the Primary Management Unit are not eligible for management.

Default Enabled Format switch unit priority value Mode Global Config

switch renumber

Use this command to change the switch identifier for a switch in the stack. The oldunit is the current switch identifier on the switch whose identifier is to be changed. The newunit is the updated value of the switch identifier. When you issue the command, the switch is configured with the configuration information for the new switch, if any. The old switch configuration information is retained, however the old switch becomes operationally unplugged. You issue this command on the Primary Management Unit.

Note: If the management unit is renumbered, the running configuration is no

longer applied (that is, the stack functions as if the running configuration is cleared).

Default None Format switch oldunit renumber newunit Mode Global Config

movemanagement (Stack Global Config)

Use this command to move the Primary Management Unit functionality from one switch to another. The fromunit is the switch identifier on the current Primary Management Unit. The tounit is the switch identifier on the new Primary Management Unit. When you issue the command, 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, you must perform all stack management capability on the new Primary Management Unit. To preserve the current configuration across a stack move, issue the copy system:running-config nvram:startup-config command in Privileged EXEC mode before performing the stack move. A stack move causes all routes and layer 2 addresses to be lost. You issue this command on the Primary Management Unit. The system prompts you to confirm the management move.

Note: The movemanagement command does not perform nonstop

forwarding (NSF). To move the management unit to the backup unit, issue the initiate failover command instead. For more information, see initiate failover (for stack configuration) on page 49.

Stacking Commands

M4200 and M4300 Series ProSAFE Managed Switches

Default None Format movemanagement fromunit tounit Mode Stack Global Config

standby

Use this command to configure a unit as a Standby Management Unit (STBY). The unit number is the unit number that must become the Standby Management Unit. The unit number must be a valid unit number.

Default None Format standby unit number Mode Stack Global Config

Note: The Standby Management Unit cannot be the current Management

Unit. The Standby unit must be a management-capable unit.

no standby

Use this command to let the switch run the auto Standby Management Unit.

Format no standby Mode Stack Global Config

slot (for stack configuration)

Use this command to configure a slot in the system. The unit/slot is the slot identifier of the slot. The cardindex is the index into the database of the supported card types, indicating the type of the card that is being preconfigured in the specified slot. The cardindex is a 32-bit integer. If a card is present in the slot that is unconfigured, the configured information is deleted and the slot is reconfigured with default information for the card.

Default None Format slot unit/slot cardindex Mode Global Config

Note: You can obtain the card index by issuing the show supported

cardtype command in User EXEC mode.

Stacking Commands

M4200 and M4300 Series ProSAFE Managed Switches

no slot

Use this command to remove configured information from an existing slot in the system.

Format no slot unit/slot cardindex Mode Global Config

Note: You can obtain the card index by issuing the show supported

cardtype command in User EXEC mode.

set slot disable (for stack configuration)

Use this command to configure the administrative mode for a specified slot or for all slots. If you specify all, the command is applied to all slots, otherwise the command is applied to the slot that is identified by unit/slot.

If a card or other module is present in the slot, the administrative mode is applied to the contents of the slot. If the slot is empty , the administrative mode is applied to any module that is inserted into the slot. If a card is disabled, all the ports on the device are operationally disabled and shown as “unplugged” on management screens.

Default None Format set slot disable [unit/slot | all] Mode Global Config

no set slot disable

Use this command to remove the administrative mode for a specified slot or for all slots. If you specify all, the command removes the administrative mode from all slots, otherwise the command removes the administrative mode from the slot that is identified by unit/slot.

If a card or other module is present in the slot, the administrative mode removes the configuration from the contents of the slot. If the slot is empty, the administrative mode removes the configuration from any module inserted into the slot. If a card is disabled, all the ports on the device are operationally disabled and shown as “unplugged” on management screens.

Format no set slot disable [unit/slot | all] Mode Global Config
