Usage Guidelines

The shutdown command causes a port to stop forwarding. The default state for a user network interface

(UNI) or enhanced network interface (ENI) is shut down. Before you can configure a UNI or ENI, you

must enable it with the no shutdown command. Network node interfaces (NNIs) are enabled by default.

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.

These examples show how to disable and re-enable a port:

Switch(config)# interface gigabitethernet0/2

Switch(config-if)# shutdown

Switch(config)# interface gigabitethernet0/2

Switch(config-if)# no shutdown

You can verify your settings by entering the show interfaces privileged EXEC command.
