There are no test commands just debug commands you can run. To test your radius setup, there are some free radius test tool and utilities you can try. Just google that and you will find a bunch. If the WLC and Radius are communicating correctly, you will see that in the logs on the radius server. You will also see the reason the user failed. The WLC logs will also show if The AAA server was unavailable or if it was a user failure.
Ill also add -- You will want to make sure your EAP is properly incofigured in your radius server. Also, check the radius failure logs as they can add good information as well..
