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:

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 CLI Command Reference 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.
