Opened: Feb 04, 2015
Severity: 4-Minor


Valid sessions may be deleted after the session timeout period expires with no subscriber traffic, even if RADIUS accounting updates are being sent within the timeout period.


Valid sessions fail due to lack of activity and the user must re-authenticate. RADIUS Accounting-Request updates are not sufficient to keep the sessions open.


Sessions are created through RADIUS and remain open with no subscriber traffic for 2 minutes or longer.



Fix Information

Alive or Valid sessions won't be deleted before the timeout any more due to a lack of traffic.
