EAP-TLS problem

Hi, I am trying to understand EAP-TLS. I have googled a lot, and found many information about EAP-TLS. So I well aware of, how EAP-TLS works, its benefits etc etc. Now I want to practically test EAP-TLS with freeradius on REDHAT 5. I have configured eap.confg to use EAP-TLS. But i don't know , how to send requests to freeradius server, so that he can authenticate the user using TLS (with digital certificate). Can anyone help me, thanks in advance..
