Configuring Dynamic VLAN Subinterfaces Based on Agent Circuit Identifier Information

The procedure you use to configure a dynamic VLAN subinterface that is based on agent-circuit-identification information is similar to the procedure described in Configuring a Dynamic VLAN Subinterface.

1. Configure profiles containing characteristics for the dynamic upper-interface encapsulation types to be created over the dynamic VLAN subinterface.
2. (Optional) If you want to create a nested profile assignment, create the profile for an upper-interface encapsulation type, and include additional profile characteristics for other encapsulation types as needed.
3. Create the base profile for the dynamic VLAN subinterface and enter Profile Configuration mode by assigning the profile a name.

   host1(config)#profile vlanMyBaseProfile

4. Define attributes for the VLAN subinterface in the base profile.
   1. Enable autoconfiguration for the PPPoE upper-interface encapsulation type.
   2. Enable autoconfiguration for the IP upper-interface encapsulation type.
   3. Enable autoconfiguration of VLANs that are based on agent-circuit-identifier information.
   4. (Optional) Create nested profile assignments for the upper-interface encapsulation types.

      host1(config-profile)#vlan auto-configure pppoe

      host1(config-profile)#vlan auto-configure ip

      host1(config-profile)#vlan auto-configure agent-circuit-identifier

      host1(config-profile)#exit

      host1(config)#

5. Configure the VLAN major interface.

   host1(config)#interface gigabitEthernet 5/0

   host1(config-if)#encapsulation vlan

6. On the VLAN major interface, configure a VLAN range that is based on agent-circuit-identifier information, and assign a name to this range.

   host1(config-if)#vlan bulk-config myNewBulkConfig svlan-range 50 100 agent-circuit-identifier

7. Assign the base profile configured for the VLAN subinterface to the VLAN range configured on the major VLAN interface.

   host1(config-if)#profile vlan bulk-config myNewBulkConfig vlanMyBaseProfile

8. Configure the VLAN major interface to support autodetection of the VLAN dynamic encapsulation type.

   host1(config-if)#auto-configure vlan
