IEEE 802.1X and RADIUS
An access point supporting IEEE 802.1X can be configured to communicate with two RADIUS
servers. When the primary RADIUS server fails to respond, the wireless access point will try to
communicate with the secondary RADIUS server. You can specify the length of timeout and the
number of retries before communicating with the secondary RADIUS server after failing to
communicate with the primary RADIUS server.
An IEEE 802.1X-capable wireless access point and its RADIUS server(s) share a secret key so
that they can authenticate each other. In addition to its IP address, a wireless access point can
identify itself by an NAS (Network Access Server) identifier. Each IEEE 802.1X-capable wireless
access point must have a unique NAS identifier.
