Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface vlanif vlan-id
A VLANIF interface is created and the VLAIF interface view is displayed.
The VLAN ID specified in this command must be the ID of an existing VLAN.
NOTE
A VLANIF interface is Up only when at least one physical port added to the corresponding VLAN is Up.

3.4.3 Assigning an IP Address to a VLANIF Interface
As a VLANIF interface is a Layer 3 logical interface, it can communicate with other interfaces
at the network layer only after being assigned an IP address.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface vlanif vlan-id
The VLANIF interface view is displayed.
The VLAN ID specified in this command must be the ID of an existing VLAN.
Step 3 Run:
ip address ip-address { mask | mask-length } [ sub ]
An IP address is assigned to the VLANIF interface for communication at the network layer.
----End
3.4.4 (Optional) Setting a Delay After Which a VLANIF Interface
Goes Down
Setting a delay after which a VLANIF interface goes Down prevents network flapping caused
by changes of VLANIF interface status. This function is also called VLAN damping.
Context
If a VLAN goes Down because all ports in the VLAN go Down, the system immediately reports
the VLAN Down event to the corresponding VLANIF interface, instructing the VLANIF
interface to go Down.
