Figure 7-5 EAP Authentication
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.
7.7 Local User Database
By storing user profiles locally on the ZyWALL, your ZyWALL is able to authenticate wireless users
without interacting with a network RADIUS server. However, there is a limit on the number of users you
may authenticate in this way.
7.8 Configuring 802.1X
