ISE 1.2 - WLC 5508 (7.5x) - Windows 7 802.1X

Hi ,

We deployed ISE 1.2 (patch 3) with 5580 WLC to authenticate machines and users using 802.1x .

We are experiencing a strange issue - randomly some machines authenticate fine over wireless and we are able to see logs on ISE and nexst day the same machine stops authenticating itself and ISE doesnt generate any log.. seems like somehow no request is coming to ISE.

we have checked all the settings including wireless settings ,services, 802.1x settings on the laptop but struggling to find the a reason why randomly machine would work and then not work.

whenever a machine works we see all the logs but when a machine doesnt work no log is generated in ise.

has anyone experienced a similar issue?

Thanks

Are you sure the machine is getting to the ISE? In the past we sometimes had trouble with the WLC itself not sending some requests to the ISE.

Have you changed the IP of the ISE and or do you have a syslog server?

Thanks, we have figured it out.

Machine Auth timer would expire after 12 hours and ISE had another setting where it would blacklist the client and supress logs for an hour if it sees more then certain amount of failed authentication attempts.

Thanks

Hello, actually version 7.5 of WCL this "EOL ^ ^" or "out of service" that has artos bugs, if you look again to download it you can no longer, the version more stable the 7.4, I recommend you to do downgrade. The problem is in the WLC v7.5

Regards!
