Configuring S-VLAN Subinterfaces over Bridged Ethernet

To configure an S-VLAN subinterface over bridged Ethernet:

Create an ATM 1483 subinterface and associated PVC.host1(config)#interface atm 3/1.1 host1(config-subif)#atm pvc 1 5 33 aal5snap 0 0 0
Specify bridged Ethernet as the encapsulation method for the ATM 1483 subinterface.host1(config-subif)#encapsulation bridge1483
Create a VLAN major interface by specifying VLAN as the encapsulation method for the bridged Ethernet interface.host1(config-subif)#encapsulation vlan
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 3/1.1.1
Assign an S-VLAN ID and a VLAN ID for the subinterface.host1(config-subif)#svlan id 4 255
Assign an S-VLAN Ethertype.host1(config-subif)#svlan ethertype 9200

Proceed to Configuring Higher-Level Protocols over S-VLANs for information about configuring higher-level protocols over the S-VLAN subinterfaces.

svlan ethertype

Use to assign an Ethertype value for the S-VLAN subinterface.
Choose one of the following Ethertype values:
- 8100—Specifies Ethertype value 0x8100, as defined in IEEE Standard 802.1q
- 9100—Specifies Ethertype value 0x9100, which is the default
- 9200—Specifies Ethertype value 0x9200
Use an Ethertype value that matches the Ethertype value set on the customer premises equipment (CPE) to which your router connects.
Examplehost1(config-if)#svlan ethertype 8100
Use the no version to restore the default value, 9100.
See svlan ethertype.

svlan id

Use to assign S-VLAN IDs and VLAN IDs to VLAN subinterfaces.
Use S-VLAN ID and VLAN ID numbers that are in the range 0–4095 and that are unique within the Ethernet interface.
Issue the svlan id command before any upper bindings are made, such as IP or PPPoE.
Examplehost1(config-if)#svlan id 4 255
There is no no version.
See svlan id.
