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:

• Licensing and Command Support

• Command Syntax

• Command Conventions

• Common Parameter Values

• Slot/Port Naming Convention

• Using a Command’s “No” Form

• Managed Switch Modules

• Command Modes

• Command Completion and Abbreviation

• CLI Error Messages

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.

Command Conventions

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. 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)

Using the Command-Line Interface

ProSafe M4100 and M7100 Managed Switches

Table 2. Parameter Descriptions (Continued)

Parameter Description

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 slot/port to configure the port-channel.

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

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

Slot/Port Naming Convention

Managed switch software references physical entities such as cards and ports by using a 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.

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.

Using the Command-Line Interface

ProSafe M4100 and M7100 Managed Switches

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

• 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, except for the User EXEC mode

Using the Command-Line Interface

ProSafe M4100 and M7100 Managed Switches

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.
