Authentication Process - Avaya AP-4 User Manual

Authentication Process

There are three main components in the authentication process. The
standard refers to them as:
1. supplicant (client PC)
2. authenticator (Access Point)
3. authentication server (RADIUS server)
When using Authentication Mode is set to 802.1x, WPA, or Mixed mode
(802.1x and WEP), you need to configure your RADIUS server for
authentication purposes.
Prior to successful authentication, an unauthenticated client PC cannot
send any data traffic through the AP device to other systems on the LAN.
The AP inhibits all data traffic from a particular client PC until the client PC
is authenticated. Regardless of its authentication status, a client PC can
always exchange 802.1x messages in the clear with the AP (the client
begins encrypting data after it has been authenticated).
