Configuring VLAN Subinterfaces over Bridged Ethernet

To configure a VLAN subinterface over bridged Ethernet:

1. Create an ATM 1483 subinterface and associated PVC.

   host1(config)#interface atm 4/0.101

   host1(config-subif)#atm pvc 1 0 32 aal5snap 0 0 0

2. Specify bridged Ethernet as the encapsulation method for the ATM 1483 subinterface.

   host1(config-subif)#encapsulation bridge1483

3. Create a VLAN major interface by specifying VLAN as the encapsulation method for the bridged Ethernet interface.

   host1(config-subif)#encapsulation vlan

4. Create a VLAN subinterface to carry the higher-level protocols by adding a subinterface number to the interface identification command.

   host1(config-subif)#interface atm 4/0.101.1

5. Assign a VLAN ID for the subinterface.

   host1(config-subif)#vlan id 10

6. (Optional) Configure additional VLAN subinterfaces by repeating Steps 4 and 5, using unique values.

   host1(config-subif)#interface atm 4/0.101.2

   host1(config-subif)#vlan id 11

Proceed to the next section for instructions on configuring higher-level protocols over the VLAN subinterfaces.
