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 P-330W acts as a message relay 
between the wireless station and the network RADIUS server. 

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.

• Access-Reject

Sent by a RADIUS server rejecting access.

• Access-Accept

Sent by a RADIUS server allowing access. 

Sent by a RADIUS server requesting more information in order to allow access. The access 
point sends a proper response from the user and then sends another Access-Request message. 

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

Sent by the access point requesting accounting.

Sent by the RADIUS server to indicate that it has started or stopped accounting.
