Negating the Effect of Commands
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 guide describes the negation effect for all applicable commands.
Command Completion
If the command entered is incomplete, invalid, or has missing or invalid
parameters, an appropriate error message is displayed.
To complete an incomplete command, press the <Tab> button. If the
characters already entered are not enough for the system to identify a single
matching command, press "?" to display the available commands matching
the characters already entered.
Incorrect or incomplete commands are automatically re-entered next to the
cursor. If a parameter must be added, the parameter can be added to the basic
command already displayed next to the cursor. The following example
indicates that the command interface requires a missing parameter.
(config)#interface
%missing mandatory parameter
(config)#interface
Keyboard Shortcuts
The CLI has a range of keyboard shortcuts to assist in entering the CLI
commands.
The following table describes these shortcuts:
Keyboard Key Description
Up-arrow key Recalls commands from the history buffer,
beginning with the most recent command. Repeat
the key sequence to recall successively older
commands.
Down-arrow key Returns the most recent commands from the
history buffer after recalling commands with the up
arrow key. Repeating the key sequence will recall
successively more recent commands.
