IEEE 802.1x Authentication Process
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.
