Radius Settings
Radius servers provide centralized authentication services to wireless clients. Two Radius
servers can be defined, one acting as a primary, the other acting as a backup.
Two user authentication methods can be enabled: one based on MAC address filter, the other
based on 802.1x EAP/MD5 authentication.
MAC address filtering based authentication requires a MAC address filter table to be created in
either the 802.11G ACCESS POINT and/or the Radius server. During the Authentication
phase of a wireless station, the MAC address filter table is searched for a match against the
wireless client’s MAC address to determine whether the station is to be allowed or denied to
access the network.
The Radius server can also be used for 802.1x EAP/MD5 authentication. IEEE 802.1x is an
IEEE standard which is based on a framework that involves stations to be authenticated
(called Supplicant), an authentication server (a Radius Server) that provides authentication
services, and an authenticator that provides necessary translation and mediating functions
between the authentication server and stations to be authenticated, in this case your 802.11G
ACCESS POINT.
