WAAS Express utilizes Cisco Classification Policy Language (C3PL) similar to those used by features like QoS and zoned-based firewall. The first time the WAAS Express is enabled, the default policy map, class maps, and parameter map will be generated. The default policy map and parameter maps are named waas_global. The WAAS Express-related policy map, class map, and parameter map are of type waas.
