I have created a new SSID with Open + MAC auth to an ACS server and a new VLAN on an AIR-AP1231G-A-K9 AP running 12.3(7)JA2. The WEP key negotiates on the client just fine, but the AP shows that the client MAC auth fails. The ACS server shows no failed attempts. The client does not recieve an IP address. VLAN is properly configured because everything works if I remove the MAC auth piece on AP. Ideas?
