I have wired 802.1x deployed with XP SP3 & Vista SP1 clients on a 3560 running the latest 12.2(50)SE software. Radius is handled by a Windows 2003 Server & IAS and reauthentication is enabled using the server to provide the timeout (session-timeout set to 180 minutes). This all appears to work but reauthentication seems to be happening more frequently than the supplied timeout. The logs filtered for 1 port are attached.
The times between reauthentications is also not consistent (23-minutes, 5.5-minutes, 23-minutes, 5.5-minutes, 37-minutes, 5.5-minutes, 30-seconds, 26.5-minutes, 5.5-minutes, 17.5-minutes)
I am not sure if the client is initiating the reauthentication but I don't remember seeing any settings in either XP or Vista for timers? I have also looked at the GPO settings and there is nothing about reauthentication timers (XP SP3 & Vista can get the Wired 802.1x settings from GPO).
Has anyone else seen this? Is it the client or is it the switch? Is it fixable?
