Guidelines for Overriding the PPPoE Maximum Session Value

The following rules apply if you configure the router to override the current PPPoE maximum session value for the interface with the PPPoE maximum session value returned by RADIUS in the Max-Clients-Per-Interface VSA:

• If the current PPPoE maximum session value is less than the PPPoE maximum session value returned by RADIUS, the PPPoE application overrides the current maximum session value with the value returned by RADIUS and proceeds with creation of the PPPoE interface.
• If the current number of active PPPoE sessions, including the current session, is greater than the PPPoE maximum session value returned by RADIUS, PPPoE ignores (drops) the new session.
• If the current number of active PPPoE sessions is less than or equal to the PPPoE maximum session value returned by RADIUS, PPPoE proceeds with creation of the PPPoE interface.

The following table shows examples of the PPPoE maximum session value when a new subscriber logs in, and indicates the status of the current session.
