Temporarily disabling a port
To temporarily disable a port without changing its stored configuration attributes, enter the following command at
any prompt:
Switch# interface gigabitethernet <port number> shutdown
Because this configuration sets a temporary state for the port, you do not need to perform a save operation. The
port state reverts to its original configuration when the switch is reloaded.
