1.3 CAPWAP
The ZyXEL Device supports CAPWAP (Control And Provisioning of Wireless Access
Points). This is ZyXEL’s implementation of the IETF’s (Internet Engineering Task Force)
CAPWAP protocol.
ZyXEL’s CAPWAP allows a single access point to manage up to eight other access points. The
managed APs receive all their configuration information from the controller AP. The
CAPWAP dataflow is protected by DTLS (Datagram Transport Layer Security).
At the time of writing, the NWA-3160 is the only ZyXEL AP model that can be a CAPWAP
controller.
At the time of writing, the following ZyXEL AP models can be CAPWAP managed APs:
• NWA-3160
• NWA-3163
• NWA-3500
• NWA-3550
• NWA-8500
The following figure illustrates a CAPWAP wireless network. The user (U) configures the
controller AP (C), which then automatically updates the configurations of the managed APs
(M1 ~ M4).
