    Configuring Dynamic PPPoE over Static PPPoE with Ethernet and S-VLAN Interface Columns

    Figure 1 shows dynamic PPPoE subinterface columns over PPPoE major interfaces using S-VLANs over Ethernet.

S-VLAN Interface Columns

    To configure an S-VLAN subinterface to support a dynamic PPPoE subinterface:

    1. Specify a Fast Ethernet, Gigabit Ethernet, or 10-Gigabit Ethernet interface.
      host1(config)#interface fastEthernet 4/1
    2. Specify VLAN as the encapsulation method.
      host1(config-if)#encapsulation vlan

      This command creates the VLAN major interface.

    3. Create a VLAN subinterface by adding a subinterface number to the interface identifier.
      host1(config-if)#interface fastEthernet 3/1.1
    4. Assign an S-VLAN ID and a VLAN ID for the subinterface.
      host1(config-if)#svlan id 3 300
    5. Assign an S-VLAN Ethertype.
      host1(config-if)#svlan ethertype 9200
    6. Specify PPPoE as the encapsulation method on the interface.
      host1(config-subif)#encapsulation pppoe

      This command creates the PPPoE major interface.

    7. Assign a profile.
      host1(config-subif)#pppoe profile pppoeProfile3

      The default encapsulation type, any, applies to any autoconfigured encapsulation that does not have a specific profile assignment.

    8. Configure the interface to detect and accept dynamic PPPoE subinterfaces.
      host1(config-subif)#pppoe auto-configure
