Hi,
We are running ISE 3.2 Patch 3 and using EAP-TLS. We are performing both machine and user authentication. We are seeing issues with a large number of '5440 Endpoint abandoned EAP session and started new'. The issue we have is that they seem to be happening at entirely random intervals, sometimes the client will authenticate ok and sometimes they won't. Sometimes they will abandon the session and re-auth within a second or two without issue and sometimes they will just not auth at all and the Windows 20 minute 802.1X block timer will run.
Anyone able to help!?
Thanks
