Chapter 18 Port Authentication authentication request to a RADIUS server. The RADIUS server validates whether this client is allowed access to the port. Figure 112 IEEE 802.1x Authentication Process 1 New Connection 2 Login Info Request 3 Login Credentials 4 Authentication Request 5 Authentication Reply Session Granted/Denied 18.1.2 MAC Authentication MAC authentication works in a very similar way to IEEE 802.1x authentication. The main difference is that the Switch does not prompt the client for login credentials. The login credentials are based on the source MAC address of the client connecting to a port on the Switch along with a password configured specifically for MAC authentication on the Switch.
