WPA reauthentication interval

[zhenningx]

We use WPA and PEAP MSchapv2 with Airespace controller 4.0 and ACS 4.0 server. On the ACS radius logs, clients who passed the authenticaoin get reauthenticaion every 6 hours. Anyone know how this 6 hours interval come from? Is it configurable somewhere? I have disabled the WLAN session timeout at Airespace and leave the PEAP session timeout value at ACS to be default 120 minutes. I expect the WPA reauthentican happens every 120 minutes, but it turns out to be every 6 hours which confusing me. Thanks.

Enter the number of seconds a client device must wait before it can reattempt to authenticate following a failed authentication. The holdoff time is invoked when a client fails three login attempts or fails to respond to three authentication requests from the access point. Enter a value from 1 to 65555 seconds.
