We keep get the following error. And everytime we got this, the clients have been force to re-authentication.
Any idea?
Thanks,
RADIUS server 10.108.32.33:1812 activated on WLAN 1
RADIUS server 10.140.4.9:1812 deactivated on WLAN 1

Fird\st make sure these radius servers are online and are configured in your wlc properly. If they are tehn look at the server timeout in the WLC under the radius config. Its default is 2 seconds. In crease it to 10 seconds.
Monitor and see if you still get the alerts

George, tks for your reply!
I have changed the timeout to 10 secs as you suggested.
Look, the alarm message shows up only for "accounting servers" thru 1646 port
Do I really need that config ? I mean, can I use only the authentication servers (port 1645) ?
thanks in advance!!

If you are not doing accounting, you don't need that configured. Only if you are also doing accounting would you need that port open 1646.

Hi Scott... tks again!
I disabled accounting servers, then I am not seeing anymore the error message "RADIUS server X.X.X.X:1813 deactivated in global list"... But I am still seeing 2 or 3 users (out of 40) with auth problems...
pls check below screen shot
*** user julio.quintao is associated but he has just "de-authentication".... (other association without users are mobile phones) ***
Did you ever see a problem like that ?

Go to clients. Look up the client by mac address and look at the PEM state. It will tell you why the client is failing ..
DHCP_REQ is meaning there is a DHCP issue
8021x_REQ means it failed auth
You could also turn off exclude as a test, perhaps these clients are a little slow to auth.

Hi George, tks for your reply!
I got that DHCP error message... what that means ?
I confirmed no problem at DHCP server... I am using 50% of that range.....

On that WLAN do you have DHCP REQ check boxed ? If you do and you have a static ip it could reg that. You said you checked the DHCP server, but a problem with DHCP would also show that ..
