History Buffer

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

History buffer. Commands are stored in the buffer, which operates on a

First In First Out (FIFO)

basis. These commands can be recalled, reviewed, modified, and reissued. This buffer is not

preserved after switch resets.

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

number of 10 stored commands can be increased to 216. 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 in the Line command mode chapter of this

guide.

Negating Commands

For many commands, the prefix keyword

is entered to cancel the effect of a command or reset

the configuration to the default value. All configuration commands have this capability. This guide

describes the negation effect for all commands to which it applies.

Show Command

The

show

command executes in the User Executive (EXEC) and Privileged Executive (EXEC)

modes.

Command Completion

CLI can complete partially entered commands when the user presses the <tab> or <space> key.

If a command entered is not complete, is not valid, or if some parameters of the command are not

valid or missing, an error message is displayed to assist in entering the correct command. By

pressing the <tab> key, an incomplete command is changed into a complete command. If the

characters already entered are not enough for the system to identify a single matching command,

the <?>key displays the available commands matching the characters already entered.

Keyword Source or Destination

Up-arrow key

Recalls commands in the history buffer, beginning with the most recent command.

Repeats the key sequence to recall successively older commands.

Down-arrow key

Returns to more recent commands in the history buffer after recalling commands

with the up-arrow key. Repeating the key sequence recalls more recent commands

in succession.
