• Configure DHCP option 138 with the IP address of the CAPWAP AP controller on
your network.
DHCP Option 138 allows the CAPWAP management request (from the AP in
managed AP mode) to reach the AP controller in a different subnet, as shown in
the following figure.

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.
