Before configuring a VLAN interface, create the corresponding VLAN.  

Follow these steps to make basic VLAN interface configuration: 

Enter system view 

system-view 

— 

Create a VLAN interface and 
enter VLAN interface view 

interface Vlan-interface 
vlan-id 

Required 

By default, there is no VLAN interface 
on a switch. 

Specify the description string 
for the current VLAN 
interface 

description text 

Optional 

By default, the description string of a 
VLAN interface is the name of this 
VLAN interface. “Vlan-interface1 
Interface” for example.  

Disable the VLAN interface 

shutdown 

Enable the VLAN Interface 

undo shutdown 

Optional 

By default, the VLAN interface is 
enabled. In this case, the VLAN 
interface’s status is determined by the 
status of the ports in the VLAN, that is, 
if all ports of the VLAN are down, the 
VLAN interface is down (disabled); if 
one or more ports of the VLAN are up, 
the VLAN interface is up (enabled). 

If you disable the VLAN interface, the 
VLAN interface will always be down, 
regardless of the status of the ports in 
the VLAN.  

 

The operation of enabling/disabling a VLAN’s VLAN interface does not influence the physical status of 

the Ethernet ports belonging to this VLAN.
