LWAPP Overview
Lightweight Access Point Protocol (LWAPP) is the underlying protocol used in Cisco’s centralized
WLAN architecture. It provides for the configuration and management of WLAN(s), in addition to
tunneling WLAN client traffic to and from a centralized WLAN controller (WLC).

Note
Because the foundational WLAN features are the same, the term WLC is used generically to represent
all Cisco WLAN Controllers, regardless of whether the controller is a standalone appliance, an ISR with
a WLC module; or a Catalyst switch with a service module or integrated WLC.
