4.4.3 RADIUS
Remote Authentication Dial-in User Service (RADIUS) is an authentication
protocol that uses software running on a central server to control access to
RADIUS-aware devices on the network. An authentication server contains a
database of user credentials for each user that requires access to the network.
A primary RADIUS server must be specified for the AP to implement IEEE 802.1X
network access control and WiFi Protected Access (WPA) wireless security. A
secondary RADIUS server may also be specified as a backup should the primary
server fail or become inaccessible.
In addition, the configured RADIUS server can also act as a RADIUS Accounting
server and receive user-session accounting information from the AP. RADIUS
Accounting can be used to provide valuable information on user activity in the
network.
NOTE
This manual assumes that you have already configured RADIUS server(s) to support the AP.
Configuration of RADIUS server software is beyond the scope of this manul, refer to the
documentation provided with the RADIUS server software.
