Vlan - H3C MSR Series Command Reference Manual

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

Default command level
2: System level
Usage guidelines
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.

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