This page allows you to configure the IEEE 802.1X and MAC-based authentication system and
port settings.
The IEEE 802.1X standard defines a port-based access control procedure that prevents
unauthorized access to a network by requiring users to first submit credentials for
authentication. One or more central servers, the backend servers, determine whether the user is
allowed access to the network. These backend (RADIUS) servers are configured on the
"Configuration→Security→AAA" page. The IEEE802.1X standard defines port-based
operation, but non-standard variants overcome security limitations as shall be explored below.
MAC-based authentication allows for authentication of more than one user on the same port,
and doesn't require the user to have special 802.1X supplicant software installed on his system.
The switch uses the user's MAC address to authenticate against the backend server. Intruders
can create counterfeit MAC addresses, which makes MAC-based authentication less secure
than 802.1X authentication.
