7.2.4 Notes on CAPWAP

This section lists some additional features of ZyXEL's implementation of the CAPWAP protocol.
• When the AP controller uses its internal Remote Authentication Dial In User Service (RADIUS)
server, managed APs also use the AP controller's authentication server to authenticate wireless
clients.
• If a managed AP's link to the AP controller is broken, the managed AP continues to use the
wireless settings with which it was last provided.

7.3 The Management Mode Screen

Use this screen to configure the device as an a controller of managed devices, a standalone AP, or a
managed AP.
Note: After you change the operation mode, the device resets to its default settings for
the mode you set it to, including the IP address of 192.168.1.2. It also backs up its
configuration to a xxx-backup.conf file where xxx denotes the mode the device was
previously using.
