Chapter 2: Using the Command-Line Interface 13
Using the no Form of a Command
The
no
keyword is a specific form of an existing command and does not represent
a new or distinct command. Almost every configuration command has a
no
form.
In general, use the
no
form to reverse the action of a command or reset a value
back to the default. For example, the
no shutdown
configuration command
reverses the shutdown of an interface. Use the command without the keyword
no
to re-enable a disabled feature or to enable a feature that is disabled by default.
Only the configuration commands are available in the
no
form.
