• Comprehensive QoS Configuration
• 9-1: Modular QoS Command-Line Interface (MQC)—A “user-friendly” way to configure all QoS features within a single framework. This framework is based on the Diffserv model. Traffic is defined as class maps; class maps are used in policy maps; policy maps are applied to interfaces. You should consider using the modular QoS CLI rather than configuring a variety of individual QoS features, just for its intuitive and structured approach.
Class maps perform versatile traffic classification. Policy maps define QoS policies by using traffic marking (reclassification), congestion management ...
