Description

Use shutdown to manually shut down a VLAN interface.

Use undo shutdown to cancel the action of shutting down a VLAN interface.

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

A VLAN interface shut down with the shutdown command is in DOWN (Administratively) state until you bring it up, regardless of how the state of the ports in the VLAN changes.

Before configuring parameters for a VLAN interface, shut down the VLAN interface with the shutdown command to prevent the configurations from affecting the network. 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 if 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
