This procedure is likely to leave your switch virtual interface in a shutdown state. You can see
which interface is in this state by entering the show running-config privileged EXEC command.
To re-enable the interface, enter the interface vlan vlan-id global configuration command, and
specify the VLAN ID of the shutdown interface. With the switch in interface configuration
mode, enter the no shutdown command.
