Currently i configure for a customer project NAC (Netsight 188.8.131.52) with X440-G2 (EXOS 184.108.40.206). On every port MAC and 802.1x - Multi-User / Multi-Method Authentication - to be mostly flexibel. 802.1x is prefered on the switch (compare to mac).
The used alcatel Phones coming with a working 802.1x supplicant (EAP-TLS) - because this is step 2 or 3 (making EAP-TLS working) i ignore TLS (and the resulting RADIUS reject). I configure MAC Auth correctly and end-systems will result an accept.
To avoid loosing voip end-systems out of NAC Database (because of purging end-systems older than 90 days) i added an RADIUS Accept Attribute to this voip phones - Session Timeout = xx seconds. For testing purpose i set this to 60 seconds.
So this work fine. Voip phones are authenticated at startup with mac successfully (dot1 was rejected). After that i can see with tcpdump that every 60 second the phone is re-authenticationed with mac (successfully) and dot1x (unsuccessfully - but this does not matter).
BUT i am wondering very much - NAC Manager - End-systems Events shows regarding this re-auth (or session timeout) events only the unsuccessful dot1x events - NOT the sucessful mac events (which i expect to see).
Is this explainable ?
