Using the CLI 225

Table 2-1. History Buffer

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

section of this guide.

Negating Commands

For many commands, the prefix keyword no is entered to cancel the effect of

a command or reset the configuration to the default value. Nearly 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), Privileged

Executive (Exec), Global Configuration mode, Interface Configuration mode

and all configuration submodes with command completion. Output from

show commands is paginated. Use the terminal length command to set the

number of lines displayed in a page. When the paging prompt appears, press

the space bar to display the next page of output or the enter key to display the

next line of output.

Example:

console>en

console#configure

Keyword Source or Destination

recalling commands with the up-arrow key. Repeating the key

sequence recalls more recent commands in succession.
