RFC – Control and Provisioning of Wireless Access Points (CAPWAP) Protocol Base MIB

As shown in Figure 1the wireless frames received from a mobile device, which is referred to in this specification as a Station STAare directly encapsulated by the WTP and forwarded to the AC. The latter implies that the WTP performs the In either case, the L2 wireless management frames are processed locally.

Figure 2 shows the Local MAC mode, in which a station transmits a wireless frame that is encapsulated in an Allowing these functions to cawap performed from a centralized AC in an interoperable fashion increases manageability and allows network operators to more tightly control their wireless network infrastructure. To centralize the authentication and policy enforcement functions for a wireless network.

Current Status and Overview of the CAPWAP Protocol

The AC may also provide centralized bridging, forwarding, and encryption of user traffic. Centralization of these functions will enable reduced cost and higher efficiency by applying the capabilities of network processing silicon to the wireless network, as in wired LANs.

To enable shifting of the rdc protocol processing from the WTP. This leaves the time-critical applications of wireless control and access in the WTP, making efficient use of the computing power available in WTPs, which are subject to severe cost pressure. To provide an extensible protocol that is not bound to a specific wireless technology. Extensibility is provided via a generic encapsulation and transport mechanism, enabling the CAPWAP protocol to be applied to many access point types in the future, via a specific wireless binding.


Inter-AC and station-to-AC communication are strictly outside the scope of this document.
