Remote Authentication Dial-in User Service (RADIUS) is an
authentication protocol that uses software running on a cent ral
server to control access to RADIUS-aware devices on the
network. An authentication server contains a database o f user
credentials for each user that requires access to the network.
A primary RADIUS server must be specified for the acc ess point
to implement IEEE 802.1X network access control and Wi -Fi
Protected Access (WPA) wireless security. A secondary RADIUS
server may also be specified as a backup should the primar y
server fail or become inaccessible.
Note: This guide assumes that you have already configured RADIUS
server(s) to support the access point. Configuration of RADIUS
server software is beyond the scope of this guide, refer to the
documentation provided with the RADIUS server software.
