5.7 802.1x 
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. 
5.8  Introduction 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.  
 
RADIUS user is a simple package exchange in which your Prestige acts as a message relay between the 
wireless station and the network RADIUS server.  
Types of RADIUS Messages 
The following types of RADIUS messages are exchanged between the access point and the RADIUS server 
for user authentication:
