Enno Rey and Oliver Roeschke discussed good and bad protocol design as they described in detail the proprietary “Wireless LAN Context Control Protocol” (WLCCP). The WLCCP protocol is used in Cisco wireless access points for the management of multiple access point wireless infrastructures called Wireless Domain Services (WDS). From their presentation overview, “The world of ‘Enterprise WLAN solutions’ is full of obscure and ‘non-standard’ elements and technologies. One prominent example is Cisco’s Structured Wireless-Aware Network (SWAN) architecture, composed of autonomous access points combined with some components for centralized management, and still deployed in a number of corporate networks.” With that introduction they proceeded to show demos and coding used to illustrate the potential shortcomings of WLCCP. The Cisco IOS command, show wlccp wnm status can be used to reflect the status of the WLCCP link between an AP snooping on the access point.
