Usage guidelines
CAUTION:
Executing the
shutdown
command on a VLAN interface will disconnect the link of the VLAN
interface and interrupt communication. Use this command with caution.
When you use this command to shut down a VLAN interface, the VLAN interface remains in DOWN
(Administratively) state. In this case, the VLAN interface state is not affected by the state of the ports
in the VLAN.
Before you configure parameters for a VLAN interface, use this command to shut it down to prevent
the configuration from affecting the network. After you complete the VLAN interface configuration,
use the
undo shutdown
command to make the settings take effect.
To troubleshoot a failed VLAN interface, you can use the shutdown command and then the undo
shutdown
command on the interface to see whether it recovers.
In a VLAN, the state of each Ethernet port is independent of the state of the VLAN interface.

# Shut down VLAN-interface 2, and then bring it up.
