Can a user be authenticated with MAC address and EAP/TLS

Hi all, I try to authenticate my wireless user with MAC address and EAP/TLS simultaneously. I set my Cisco 1230 AP to authenticate 'with MAC address and EAP' and my wireless client as for EAP/TLS authentication because no special setting is needed for MAC authentication. However, the wireless client only do EAP/TLS, not MAC authentication. Anything that I miss? Thanks. Thanks.
