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.

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

For more information on enabling or disabling the history buffer, refer to 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 216. By configuring 0, the

effect is the same as disabling the history buffer system. For more information on

configuring the command history buffer, refer to the history size command.

To display the history buffer, refer to the show history command.

For many configuration commands, the prefix keyword no can be entered to

cancel the effect of a command or reset the configuration to the default value. This

Reference Guide provides a description of the negation effect for each CLI

command.
