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.
