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 interface

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.
