Pls attached "show wlan <wlan_id>" output. Also what is the RADIUS server you used in this 802.1X deployment, I would check RADIUS server logs as well.

Also confirm what software version (show sysinfo) you running on WLC and what AP model in used.

That's what you should be looking at - the device is not responding.
Need the info Rasika has already suggested and I'd suggest packet captures at client and radius server too.

thanks, Rasika, Rrudling

we're trying our best to get the log that you mentioned, it's hard to get from our customer side for some security reason.
