View

Parameter
None
Description
Use the shutdown command to disable the VLAN interface.
Use the undo shutdown command to enable the VLAN interface.
By default, a VLAN interface is enabled. In this scenario, a VLAN interface's status is
determined by the status of its Ethernet ports, that is, if all the Ethernet ports of the
VLAN interface are down, the VLAN interface is down (disabled); if one or more
Ethernet ports of the VLAN interface are up, the VLAN interface is up (enabled).
If a VLAN interface is disabled, its status is not determined by the status of its Ethernet
ports.
You can use the undo shutdown command to enable a VLAN interface when its
related parameters and protocols are configured. When a VLAN interface fails, you can
use the shutdown command to disable the interface, and then use the undo
shutdown command to enable this interface again, which may restore the interface.
The operation of enabling/disabling a VLAN interface does not influence all the
Ethernet ports belonging to this VLAN.
Example
# Disable Vlan-interface2.
