Use the following command to shut down/enable a VLAN interface.

Perform the following configuration in VLAN Interface View.

The operation of shutting down or enabling the VLAN interface has no effect on the 
UP/DOWN status of the Ethernet ports on the local VLAN.

By default, when all the Ethernet ports belonging to a VLAN are in DOWN status, this 
VLAN interface is also DOWN, that it, this VLAN interface is shut down. When there is 
one or more Ethernet ports in UP status, this VLAN interface is also UP, that is, this 
VLAN interface is enabled.

After the above configuration, enter the 

 command in any view to display the 

running of the VLAN configuration, and to verify the effect of the configuration.

Create VLAN2 and VLAN3. Add Ethernet1/0/1 and Ethernet1/0/2 to VLAN2 and add 
Ethernet1/0/3 and Ethernet1/0/4 to VLAN3.
