Abstract:
CAPWAP defines a specification to encapsulate a station's data frames
between the Wireless Transmission Point (WTP) and Access Controller
(AC) using CAPWAP. Specifically, the station's IEEE 802.11 data
frames can be either locally bridged or tunneled to the AC. When
tunneled, a CAPWAP data channel is used for tunneling. In many
deployments it is desirable to encapsulate date frames to an entity
different from the AC for example to an Access Router (AR). Further,
it may also be desirable to use different tunnel encapsulations to
carry the stations' data frames. This document provides a
specification for this and refers to it as Alternate tunnel
encapsulation. The Alternate tunnel encapsulation allows 1) the WTP
to tunnel non-management data frames to an endpoint different from
the AC and 2) the WTP to tunnel using one of many known encapsulation
types such as IP-IP, IP-GRE, CAPWAP. The WTP may advertise support
for Alternate tunnel encapsulation during the discovery or join
process and AC may select one of the supported Alternate Tunnel
encapsulation types while configuring the WTP.
