Use shutdown to shut down a VLAN interface.

Use undo shutdown to bring up a VLAN interface.

A VLAN interface is not manually shut down. The VLAN interface is up if one or more ports in the VLAN is up, and it goes down if all ports in the VLAN go down.

Usage guidelines

When a VLAN interface is not manually shut down, the following guidelines apply to the interface state:

• The VLAN interface is down if all ports in the VLAN are down.

• The VLAN interface is up if one or more ports in the VLAN are up.

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 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 any Ethernet port is independent of the state of the VLAN interface.

Examples

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

<Sysname> system-view
[Sysname] interface vlan-interface 2
[Sysname-Vlan-interface2] shutdown
[Sysname-Vlan-interface2] undo shutdown
