Problems with Radius authentication - WLC

I have a WLC and I have a SSID with Radius Authentication, it was working but after a while it stops working:

 

I did a tracebuf:

 


(PA-TB-WCONTROLLER01) #show auth-tracebuf mac 94:65:9c:45...
(PA-TB-WCONTROLLER01) #show auth-tracebuf mac 94:65:9c:45:7a:31

Auth Trace Buffer

Re: Problems with Radius authentication - WLC

Was that client previously successful at authentication?

 

What is providing the radius service? Can you check to see if the requests are hitting the server?

Re: Problems with Radius authentication - WLC

Test using the controller aaa test server
Make sure your certificate hasn't expired ?
Have you guys made any changes on the RADIUS server shared key or the NAS IP address on the controller?
Thank you

Re: Problems with Radius authentication - WLC

The client seems to be failing when the AP/Controller asks for an EAP-ID request.  What client is this and how is the client configured for 802.1x?
