How do the WDS and the infrastructure APs in the WLAN communicate with each other?
A. The WDS and the infrastructure APs communicate over a multicast protocol called the Wireless LAN Context Control Protocol (WLCCP). These multicast messages cannot be routed. Therefore, a WDS and the associated infrastructure APs must be in the same IP subnetwork and on the same LAN segment. Between the WDS and the Wireless LAN Solution Engine (WLSE), WLCCP uses Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) on port 2887. When the WDS and WLSE are on different subnetworks, packet translation with a protocol like Network Address Translation (NAT) cannot occur.
