Figure 67 IEEE 802.1x Authentication Process
16.1.2 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.
