I have a mixed setup of WLC and autonomous AP in my network architecture. In our setup all wireless clients passes through mac authentication and then user id/password authentication. I want for mac authentication request should go to ACS server 1 while for user credential verification the request should go to server2 . In auto nomous AP i can achieve the requirement with folowing configuration.
aaa group server radius rad_eap
server 172.X.Y.103 auth-port 1812 acct-port 1813
aaa group server radius rad_mac
server 172.X.Y.104 auth-port 1812 acct-port 1813
aaa authentication login mac_methods group rad_mac
aaa authentication login eap_methods group rad_eap
If you want to do MAC filtering on one WLAN and standard 802.1x on another you can select which RADIUS server to use is the Security tab -> AAA Servers of each WLAN. To do both on the same WLAN there is no functionality on the WLC to allow you to split the roles the way you want to. Sorry.
