11.1.1 What You Can Do in the RADIUS Screen
Use the Security > RADIUS screen (see Section 11.2 on page 171 ) if you want
to authenticate wireless users using a RADIUS Server and/or Accounting Server.
11.1.2 What You Need To Know About RADIUS
The RADIUS server handles the following tasks:
• Authentication which determines the identity of the users.
• Authorization which determines the network services available to
authenticated users once they are connected to the network.
• Accounting which keeps track of the client’s network activity.
RADIUS is a simple package exchange in which your AP acts as a message relay
between the wireless client and the network RADIUS server.
You should know the IP addresses, ports and share secrets of the external RADIUS
server and/or the external RADIUS accounting server you want to use with your
NWA. You can configure a primary and backup RADIUS and RADIUS accounting
server for your NWA.
You can configure up to four RADIUS server profiles. Each profile also has one
backup authentication server and a backup accounting server. These profiles can
be assigned to an SSID profile in the
Wireless > SSID configuration screen.
