Fig. 45. IEEE 802.1x and RADIUS.
A WIASA supporting IEEE 802.1x can be configured to communicate with two RADIUS servers.
When the primary RADIUS server fails to respond, the WIASA 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 WIASA and its RADIUS server(s) share a secret key so that they can au-
thenticate each other. In addition to its IP address, a WIASA can identify itself by an NAS (Network
Access Server) identifier. Each IEEE 802.1x-capable WIASA must have a unique NAS identifier.

mation about deploying secure WLANs with IEEE 802.1x support.
