Configuring Radius; Figure 17-2 Eap Authentication - ZyXEL Communications ZyWALL 10W User Manual

The following figure shows an overview of authentication when you specify a RADIUS server on your
access point.
The details below provide a general description of how IEEE 802.1x EAP authentication works. For an
example list of EAP-MD5 authentication steps, see the IEEE 802.1x chapter in the Appendices.
•
The wireless station sends a "start" message to the ZyWALL.
•
The ZyWALL sends a "request identity" message to the wireless station for identity information.
•
The wireless station replies with identity information, including username and password.
•
The RADIUS server checks the user information against its user profile database and determines
whether or not to authenticate the wireless station.
