1.3 CAPWAP
The NWA supports Control And Provisioning of Wireless Access Points (CAPWAP).
This is ZyXEL’s implementation of the Internet Engineering Task Force’s (IETF)
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 Datagram Transport Layer
Security (DTLS).
The following ZyXEL AP models can be CAPWAP managed APs:
• NWA-3160
• NWA-3163
• NWA-3500
• NWA-3550
• NWA-3166
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).
