WIFI Controller C5210 - "Unable to connect to RADIUS servers"

WIFI Controller C5210 - "Unable to connect to RADIUS servers"

Greetings,

We are using an extremE controller C5210 with WS-AP3715I Access Points and are getting a "Unable to connect to RADIUS servers" when ever we want to connect.

We have rebooted the radius server and the controller to NO avail.

Any pointers?

Thanks,
Kombe

Hi

It looks like your radius server/config has some kind of issue, take a look at this thread and see if it helps (it's in multiple parts) http://lists.freeradius.org/pipermail/freeradius-users/2013-March/065439.html

Tested the RADIUS WLAN-SERVICE and got:

RADIUS Test Results:
Sending EAP authentication request to Radius Server with user admin on vns_name Link
Please wait while all configured Radius Servers on this VNS are attempted as needed ...

Test Completed.

The Radius Server did not authenticate the user admin on Link VNS. Error: ACCESS_REJECTED.

Is your Radius Server listening?
If your Radius Server is linux based, netstat -l (L for Listen) to see if that port is listening.
Telnet IP.of.radius.server Port.radius.runs.on to see if you connect. first local telnet, then remote telnet

That's a good sign!

Next, try the following...

1. Under the VNS tab---> WLAN-Service---> Select the RADIUS WLAN-Service
2. Click on the Auth & Acct tab
3. Click on the RADIUS server in your list, then click on the TEST button.
4. Enter in a User ID:
5. The process will fail (no pass is sent) but see if you get back something similar to the following:

The Radius Server did not authenticate the user dhyde on PoE VNS. Error: ACCESS_REJECTED.
