Applying Web Authentication or MAC Authentication Concurrently with Port- Based 802.1X Authentication

While 802.1X port-based access control can operate concurrently with Web Authentication or MAC Authentication, port-based access control is subordinate to Web-Auth and MAC-Auth operation. If 802.1X operates in port-based mode and MAC or Web authentication is enabled on the same port, any 802.1X authentication has no effect on the ability of a client to access the controlled port. That is, the client's access is denied until the client authenticates through Web-Auth or MAC-Auth on the port. Note: A client authenticating with port-based 802.1X does not open the port in the same way that it would if Web-Auth or MAC-Auth were not enabled. Any non-authenticating client attempting to access the port after another client authenticates with port-based 802.1X still has to authenticate through Web-Auth or MAC-Auth.
