Usage guidelines
A VLAN interface that was shut down with the shutdown command remains in DOWN (Administratively)
state until you bring it up, regardless of how the state of the ports in the VLAN changes.
Before you configure parameters for a VLAN interface, shut down the VLAN interface with the shutdown
command to prevent the configurations from affecting the network. You can use the undo shutdown
command to bring up a VLAN interface after you have configured related parameters and protocols for
the VLAN interface.
You can shut down a failed interface with the shutdown command and then bring it up with the undo
shutdown command to see whether it recovers.
In a VLAN, the state of any Ethernet port is independent of the state of the VLAN interface.

# Shut down VLAN-interface 2, and then cancel the action of manually shutting down the VLAN
interface.
