This is a "modern" way to configure FRTS, using MQC commands only to accomplish the task. With MQC approach, an unified interface has been introduced to configure all QoS settings, irrelevant of underlying technology.
This is the most well-known FRTS method, which has been available for quite a while on Cisco routers. It is now being outdated by MQC configurations. The key characteristic is that all settings are configured under map-class command mode, and later are applied to a particular set PVCs. The same configuration concept was used for legacy ATM configuration mode (map-class atm).
