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 it goes down if all ports in the VLAN go down.
Views

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.
Examples
# Shut down VLAN interface 2, and then cancel the action of manually shutting down the VLAN
interface.
<Sysname> system-view
[Sysname] interface vlan-interface 2
[Sysname-Vlan-interface2] shutdown
[Sysname-Vlan-interface2] undo shutdown

vlan-id
to create a VLAN and enter its view or to enter the view of an existing VLAN.
Use

to create VLANs
vlan-id1
through
vlan-id2
, except reserved VLANs.
Use
vlan all
to create VLANs 1 through 4094.
Use
undo vlan
to remove the specified VLANs.
