5.7802.1x Overview

The IEEE 802.1x standard outlines enhanced security methods for both the authentication of wireless stations and encryption key management. Authentication can be done using the local user database internal to the Prestige (authenticate up to 32 users) or an external RADIUS server for an unlimited number of users.

5.8Introduction to RADIUS

RADIUS is based on a client-sever model that supports authentication and accounting, where access point is the client and the server is the RADIUS server. The RADIUS server handles the following tasks among others:

•Authentication

Determines the identity of the users.

•Accounting

Keeps track of the client’s network activity.

Types of RADIUS Messages

The following types of RADIUS messages are exchanged between the access point and the RADIUS server for user authentication:
