Command History
Usage Guidelines The shutdown command causes a port to stop forwarding. You can enable the port with the no shutdown
command.
The no shutdown command has no effect if the port is a static-access port assigned to a VLAN that has
been deleted, suspended, or shut down. The port must first be a member of an active VLAN before it can
be re-enabled.
The shutdown command disables all functions on the specified interface.
This command also marks the interface as unavailable. To see if an interface is disabled, use the show
interfaces privileged EXEC command. An interface that has been shut down is shown as
administratively down in the display.
Examples These examples show how to disable and re-enable a port:
Switch(config)# interface gigabitethernet1/0/2
Switch(config-if)# shutdown
Switch(config)# interface gigabitethernet1/0/2
Switch(config-if)# no shutdown
You can verify your settings by entering the show interfaces privileged EXEC command.
