Parameters
None
Description
Use the shutdown command to administratively shut down the VLAN interface.
Use the undo shutdown command to bring up the VLAN interface.
By default, a VLAN interface is administratively enabled. In this case, the physical state of the VLAN
interface is affected by that of the ports in the VLAN.
When all the Ethernet ports in the VLAN are down, the VLAN interface of the VLAN is down, that is,
disabled.
When one or more Ethernet ports in the VLAN are up, the VLAN interface of the VLAN is up, that is,
enabled.
If you shut down the VLAN interface manually, the administrative state of the VLAN interface will always
be down, regardless of the state of the ports in the VLAN.
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.
Enabling or disabling a VLAN interface does not influence the state of the Ethernet ports belonging to
this VLAN.
