Which protocol allows a Lightweight AP (LWAP) to forward data to the wired LAN?

Control and Provisioning of Wireless Access Points (CAPWAP) is a protocol that's responsible for provisioning of LWAPs and forwarding data to the wireless LAN controller. The Spanning Tree Protocol (STP) is used to stop switching loops when redundant connections in a LAN are present. Bridge Protocol Data Units (BPDUs) are frames used by STP to define the root bridge and learn the switching topology for a network. Orthogonal Frequency Division Multiplexing (OFDM) is a wireless modulation method introduced with 802.11a.
