Shaping PPPoE Over VLAN Sessions Using RADIUS
Per Session Queuing and Shaping for PPP over Ethernet (PPPoE) over Virtual LANs (VLANs) Using
RADIUS enables you to shape PPPoE over VLAN sessions to a user specified rate. The router shapes
the sum of all of the traffic to the PPPoE session so that the subscriber's connection to the DSLAM does
not become congested. Queuing-related functionality provides different levels of service to the various
applications that execute over the PPPoE session.
A nested, two-level hierarchical service policy is used to configure session shaping directly on the router
using the modular quality of service command-line interface (MQC). The RADIUS server applies the
service policy to a particular PPPoE session by downloading a RADIUS attribute to the router. This
attribute specifies the policy map name to apply to the session. RADIUS notifies the router to apply the
specified policy to the session. Because the service policy contains queuing-related actions, the router
sets up the appropriate class queues and creates a separate versatile management system (VTMS) link
dedicated to the PPPoE session.
When configuring queuing and shaping for PPPoE over VLAN sessions, the child policy of a nested
hierarchical service policy defines QoS actions using any of the following QoS commands:
