3.6 Using CLI Command History
The CLI user interface provides a history or record of commands that you have entered. This feature is particularly
useful for recalling long or complex commands or entries, including access lists. To recall commands from the history
buffer, use one of the following commands:
Keystrokes/Command Purpose
Press
Ctrl-P
or the up arrow key
Recall commands in the history buffer, beginning with the
most recent command. Repeat the key sequence to recall
successively older commands.
Press
Ctrl-N
or the down arrow key
Return to more recent commands in the history buffer after
recalling commands with Ctrl-P or the up arrow key. Repeat
the key sequence to recall successively more recent
commands.
show history
While in EXEC mode, list the last several commands entered.
3.7 Using the No and Default Forms of Commands
Almost every router configuration command has an opposite
no
form that negates or reverses a command. In
general, the
no
form is used to disable a function that has been enabled. To re-enable a disabled function, or to
enable a function that is disabled by default, use the command without the
no
keyword. For example, Address
Resolution Protocol (ARP)
is enabled by default. Specify the command
no arp
to disable the ARP table; to re-enable
the ARP table, use the
arp
command.

•
Moving Around on the Command Line
