2How to Use 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

• The unit/port naming convention

• ‘no’ form of a command

• ‘show’ commands

• CLI output filtering

• Command completion and abbreviation

• CLI error messagesCLI line-editing conventions

• Use the CLI help

• Access the CLI

AV Line of Fully Managed Switches M4250 Series

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

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.

are parameters and represent required values that you must enter

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

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

, of a configurable setting on the device.

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

AV Line of Fully Managed Switches M4250 Series

Table 1. Parameter Conventions (continued)

Symbol Example Description

{ } curly braces {choice1 | choice2} Indicates that you must select a parameter from the

list of choices.

| 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

• a.b.c

• a.b.c.d (8.8.8.8)

In addition to these formats, the CLI accepts decimal, hexadeci formats through or decimal number):

• 0xn

• 0n

• n

Table 2. Parameter Descriptions (continued)

Parameter Description

Logical Interface Represents a logical port number. This is applicable in the case of a port-channel

(LAG). You can use the logical unit/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.

The unit/port naming convention

The switch references physical entities such as ports by using a unit/port naming convention. The switch also uses this convention to identify certain logical entities, such as port channel interfaces (link aggregation groups, abbreviated as LAGs).

The port identifies the specific physical port or logical interface.

Table 3. Types of ports

Port Type Description

Physical interfaces The physical ports are numbered sequentially starting from one. For

example, port 1 for a switch is 0/1, port 2 is 0/2, port 3 is 0/3, and so on.

Logical Interfaces • Port-channel

interfaces that are used only for bridging functions.

• VLAN

• Loopback interfaces

• Tunnel interfaces are logical point-to-point links that carry encapsulated

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

format. To a tunnel interface, you use the tunnel ID.

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

routing interfaces are used only for routing functions.

How to Use the Command-Line Interface

CLI Command Reference Manual12

AV Line of Fully Managed Switches M4250 Series

‘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.

‘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. 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, ou 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.

• 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.

- 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 CL

For new commands for the feature, see CLI Output Filtering Commands on page 150.

Command completion and abbreviation

Command completion finishes spelling the command when you type enough letters of a command to uniquely identify the command keyword. Once you have entered enough letters, press the SPACEBAR or TAB key to complete the word.

Command abbreviation allows you to execute a command when you have entered there are enough letters

to uniquely identify the command. You must enter all of the required keywords

and parameters before you enter the command.

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 29.

there is a show command that displays the configuration setting.

AV Line of Fully Managed Switches M4250 Series

Configure the Switch Management CPU

To manage the switch over the web management interface or Telnet, you must assign an IP address to the switch management CPU. You can accomplish this task through CLI commands or you can use the ezconfig tool, which simplifies the task. The tool lets you configure the following settings:

• The administrator user password and administrator-enable password

• The management CPU IP address and network mask

• The system name and location information

The tool is interactive and uses questions to guide you through

configuration steps. At the

the

end of the configuration session, the tool lets you save the information. To see which information was changed by the ezconfig tool after a configuration session, issue the show running-config command.

ezconfig

This command sets the IP address, subnet mask, and gateway of the switch. The IP address and the gateway must be on the same subnet.
