LWAPP is abbreviation for Lightweight Access Point Protocol. LWAPP was introduced in RFC5412 and defined the process of authenticating an AP with a controller, distributing firmware and configuration and defining the transport header for LWAPP traffic.
CAPWAP is abbreviation for Control and Provisioning of Wireless Access Points and interoperable protocol that enables a Wireless LAN Controller (WLC) to manage access points (AP) or wireless termination points (WTP). CAPWAP is based on the Lightweight Access Point Protocol (LWAPP).
LWAPP-enabled access points can discover and join a CAPWAP controller, and conversion to a CAPWAP controller is seamless. The LWAPP protocol was the first protocol to be proposed. It was initially designed by Airespace, which was later bought out by Cisco in 2005.
