CHAPTER 4
Management Mode
This chapter discusses the MGNT MODE (Management Mode) screen. This screen
determines whether the NWA is used in its default standalone AP mode or as part
of a CAPWAP (Control And Provisioning of Wireless Access Points) network.
4.1 About CAPWAP
The NWA supports CAPWAP (Control And Provisioning of Wireless Access Points).
This is ZyXEL’s implementation of the IETF’s (Internet Engineering Task Force)
CAPWAP protocol (RFC 4118).
The CAPWAP dataflow is protected by DTLS (Datagram Transport Layer Security).
The following figure illustrates a CAPWAP wireless network. You (U) configure the
AP controller (C), which then automatically updates the configurations of the
managed APs (M1 ~ M4).
Figure 17 CAPWAP Network Example
Note: The NWA can be a standalone AP (default) or a CAPWAP controller AP or a
CAPWAP managed AP.
