Entering Commands

A CLI command is a series of keywords and arguments. Keywords identify a

command, and arguments specify configuration parameters. For example, in

the command "show interfaces status gi0/4" show, interfaces and status are

keywords, gi is an argument that specifies the interface type, and 0/5 is an

argument that specifies the port.
To enter commands that require parameters, enter the required parameters

after the command keyword. For example, to set a password for the

administrator, enter:

console(config)# username admin password smith

Help information can be displayed in the following ways:

Keyword Lookup — The character ? is entered in place of a command. A

list of all valid commands and corresponding help messages are displayed.

Partial Keyword Lookup — A command is incomplete and the character ?

is entered in place of a parameter. The matched parameters for this

command are displayed.

The following describes features that assist in using the CLI:

Terminal Command Buffer

Every time a command is entered in the CLI, it is recorded on an internally

managed Command History buffer. Commands stored in the buffer are

maintained on a First In First Out (FIFO) basis.These commands can be

recalled, reviewed, modified, and reissued. This buffer is not preserved across

device resets. The keys that can be used to access the history buffer are

described in

Keyboard Keys

.

By default, the history buffer system is enabled, but it can be disabled at any

time. For information about the command syntax to enable or disable the

history buffer, see the

history

command.

There is a standard default number of commands that are stored in the buffer.

The standard number of 10 commands can be increased to 256. By

configuring 0, the effect is the same as disabling the history buffer system. For

information about the command syntax for configuring the command history

buffer, see the

history size

command.

To display the history buffer, see

show history

command.
