Im setting up a guest SSID for public access. I have mobility controller and CPPM. I will have an acknowledgment web portal page as the captive portal. I want the process to register the users mac addresses and want the users to be able to auth thereafter with the mac address until the re-auth interval is reached. Is it as simple as turning on mac auth in L2 and then in AAA profile? Do I need to do anything in Clearpass? Detailed instructions would be much appreciated. Thxs
