Vlan - HP 12500 Series Command Reference Manual

Syntax
shutdown
undo shutdown
Default
A VLAN interface is manually shut down. After you cancel the action of manually shutting down a
VLAN interface, 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
VLAN interface view
Predefined user roles
network-admin
mdc-admin
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
