6.6 Network Authentication

You can set the Prestige and your network to authenticate a wireless station before the wireless
station can communicate with the Prestige and the wired network to which the Prestige is
connected.

6.6.1 EAP

EAP (Extensible Authentication Protocol) is an authentication protocol designed originally to
run over PPP (Point-to-Point Protocol) frame in order to support multiple types of user
authentication. By using EAP to interact with an EAP-compatible RADIUS server, the access
point helps a wireless station and a RADIUS server to perform mutual authentication.

6.6.1.1 RADIUS

RADIUS is based on a client-sever model that supports authentication, authorization and
accounting. The access point is the client and the server is the RADIUS server. The RADIUS
server handles the following tasks:
• Authentication
Determines the identity of the users.
• Authorization
Determines the network services available to authenticated users once they are connected
to the network.
• Accounting
Keeps track of the client's network activity.
RADIUS is a simple package exchange in which your Prestige acts as a message relay
between the wireless station and the network RADIUS server.

6.6.1.2 Types of RADIUS Messages

The following types of RADIUS messages are exchanged between the access point and the
RADIUS server for user authentication:
• Access-Request
Sent by an access point requesting authentication.
