Creating Static VLAN Subinterfaces Within VLAN Subranges

You can configure a static VLAN subinterface with a VLAN whose VLAN ID falls within an existing bulk-configured VLAN subrange.

To create a static VLAN subinterface within a VLAN subrange:

1. Create the VLAN major interface.

   host1(config)#interface gigabitEthernet 0/0

   host1(config-if)#encapsulation vlan

2. Create a bulk-configured VLAN range that includes one or more VLAN subranges.

   host1(config-if)#vlan bulk-config test vlan-range 200 250

3. Create a static VLAN subinterface by adding a subinterface number to the interface identification command.

   host1(config-if)#interface gigabitEthernet 0/0.2100

4. Do one of the following:
   • Assign a VLAN ID for the subinterface.

     host1(config-if)#vlan id 201

   • Assign a VLAN ID and the optional unique MAC address for the subinterface.

     host1(config-if)#vlan id 201 mac-address 0090.1a01.1234

5. To fully configure the VLAN subinterface, assign an IP address, or make it unnumbered.

   host1(config-if)#ip unnumbered loopback 0
