Configuring Dynamic VLANs Based on Agent Circuit Identifier Information

You can configure dynamic VLAN subscriber interfaces based on agent circuit identifier (ACI) information, also known as ACI-based dynamic VLANs, for DHCP and PPPoE subscribers. To do so, you create an ACI interface set, which is a logical collection of subscriber interfaces that originate at the same household or on the same access-loop port, and then reference the ACI interface set in the dynamic profile for a PPPoE or IP demultiplexing (IP demux) logical subscriber interface.

To configure a dynamic VLAN subscriber interface based on ACI information:

  1. Configure a dynamic profile that defines the dynamic ACI interface set.
  2. (Optional) In the dynamic profile for the ACI interface set, configure the router to use the Actual-Data-Rate-Downstream VSA [26-130] or Access-Loop-Encapsulation VSA [26-144] value in PPPoE control packets to adjust CoS shaping-rate and overhead-accounting attributes at a per-household level.
  3. Dynamically or statically configure the underlying VLAN logical interface to enable dynamic subscriber interface creation based on ACI information.
  4. Associate the dynamic ACI interface set with the dynamic PPPoE or dynamic IP demux logical subscriber interface.
  5. (Optional) In the dynamic profile for the PPPoE (pp0) subscriber interface, configure the router to use the Actual-Data-Rate-Downstream VSA [26-130] or Access-Loop-Encapsulation VSA [26-144] value in PPPoE control packets to adjust CoS shaping-rate and overhead-accounting attributes at a per-subscriber level.
