2.3.2 Network
2.3.2.1 NAS
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 Authentication configuration page.
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 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 the 802.1X authentication.
