Using the CLI 169
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 on page 1519 in the Line
command mode chapter 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), config mode, interface config mode and all config
submodes such as VLAN database config mode, and interface config mode
