• Licensing and Command Support

• Command Syntax

• Command Conventions

• Common Parameter Values

• Unit/Slot/Port Naming Convention

• Using a Command’s “No” Form

• Managed Switch Modules

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 or 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 parameter, so you are not required to enter a value in place of

the parameter.

The New Template User 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.

Name with Spaces” forces the system to accept the spaces. Empty strings (““) are not valid user-defined strings. Table 2 describes common parameter values and value formatting.

Table 2. Parameter Descriptions

Parameter Description

ipaddr This parameter is a valid IP 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-address

Interface or unit/slot/port

Logical Interface

Character strings Use double quotation marks to identify character strings, for example, “System Name with

Valid slot and port number separated by forward slashes. For example, 0/1 represents slot number 0 and port number 1.

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.

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

Unit/Slot/Port Naming Convention

Managed switch software references physical entities such as cards and ports by using a unit/slot/port naming convention. The software 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.

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

Using the Command-Line Interface

ProSafe Managed Switch

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 zero. 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 a Command’s “No” Form

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 re-enable a disabled feature or to enable a feature that is disabled by default. Only the configuration commands are available in the no form.

Managed Switch Modules

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 software.

The software suite includes the following modules:

• Switching (Layer 2)

• Routing (Layer 3)

• IPv6—IPv6 routing

• Multicast

Using the Command-Line Interface

ProSafe Managed Switch

• Quality of Service

• Management (CLI, Web UI, and SNMP)

• IPv6 Management—Allows management of the device through an IPv6 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) and a routine interface (port or VLAN).

• Stacking

Not all modules are available for all platforms or software releases.

Command Modes

The CLI groups commands into modes according to the command function. Each of the command modes supports specific software 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.

Table 5 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 Router BGPv4 Command Mode.

2. Stacking Commands

This chapter contains the following sections:

• Dedicated Port Stacking

• Front Panel Stacking Commands

• Non-Stop Forwarding Commands

• Stack Firmware Synchronization Commands

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

Dedicated Port Stacking

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

stack

This command sets the mode to Stack Global Config.

Format stack Mode

Global Config

member

This command configures a switch. The <unit> is the switch identifier of the switch to be added/removed from the stack. The <switchindex> is the index into the database of the supported switch types, indicating the type of the switch being preconfigured. The switch index is a 32-bit integer. This command is executed on the Primary Management Unit.

Format member <unit> <switchindex> Mode

Stack Global Config

ProSafe Managed Switch

Note: Switch index can be obtained by executing the show supported

switchtype command in User EXEC mode.

no member

This command removes a switch from the stack. The <unit> is the switch identifier of the switch to be removed from the stack. This command is executed on the Primary Management Unit.

Format no member <unit> Mode

Stack Global Config

switch priority

This command configures the ability of a switch to become the Primary Management Unit. The <unit> is the switch identifier. The <value> is the preference parameter that allows the user to specify, priority of one backup switch over another. The range for priority is 1 to

15. The switch with the highest priority value will be chosen to become the Primary

Management Unit if the active Primary Management Unit fails. The switch priority defaults to the hardware management preference value 1. Switches that do not have the hardware capability to become the Primary Management Unit are not eligible for management.

Default Format Mode

enabled

switch <unit> priority <value>

Global Config

switch renumber

This command changes 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. Upon execution, the switch will be configured with the configuration information for the new switch, if any. The old switch configuration information will be retained, however the old switch will be operationally unplugged. This command is executed on the Primary Management Unit.

Note: If the management unit is renumbered, then the running

configuration is no longer applied (i.e. the stack acts as if the configuration had been cleared)

Stacking Commands

ProSafe Managed Switch

Format switch <oldunit> renumber <newunit> Mode

Global Config

movemanagement

This command moves 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. 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, execute the copy system:running-config nvram:startup-config (in Privileged EXEC) command before performing the stack move. A stack move causes all routes and layer 2 addresses to be lost. This command is executed on the Primary Management Unit. The system prompts you to confirm the management move.

Note: The movemanagement command does not NSF (non-stop

forwarding). To move the management unit to the backup unit, use initiate failover instead. For more information, see initiate

failover on page 32.
