MAC Filter on Cisco Catalyst AP

Hi there and merry christmas,

I configured one corporate wifi ssid with radius auth and I want to add MAC filtering for add an extra layer of security, but I cant make it possible

In EWC I check mac filter on wlan>AAA security and I added macs on config>AAA>Advanced, but still can connect with any Mac.

Anyonr can help me? This shouldnt be too much difficult, I did in some aps, but cisco is cisco :/

Thanks
