Wireless - Light Weight Access Point Protocol (LWAPP)
LWAPP, which stands for Lightweight Access Point Protocol, is a Cisco proprietary protocol used to manage and control wireless access points in large-scale wireless networks. It was primarily designed to enable centralized management of access points (APs) through wireless controllers.
LWAPP has largely been superseded by the Control and Provisioning of Wireless Access Points (CAPWAP) protocol. CAPWAP, which built upon the concepts introduced by LWAPP, has become the standard for managing wireless access points and controllers.
LWAPP should not be confused with Lightweight Access Points (LWAPs) which are simply APs that leverage a WLC
