Chapter 25 Configuring Quality of Service
Configuring Quality of Service
Traffic Classification
Classifying network traffic allows you to organize packets into traffic classes based on whether the
traffic matches specific criteria. Classifying network traffic is the foundation for enabling many QoS
features on your network. For instructions on how to configure traffic classification, see Configuring
Classification.
Traffic Marking
Marking network traffic allows you to set or modify the attributes for packets in a defined traffic class.
You can use marking with traffic classification to configure variety of QoS features for your network.
For instructions on how to configure traffic marking, see Configuring Marking.
Traffic Queuing
The Cisco MWR 2941 supports lass-Based Weighted Fair Queueing (CBWFQ) for congestion
management. CBWFQ extends the standard Weighted Fair Queueing (WFQ) functionality to provide
support for user-defined traffic classes. For CBWFQ, you define traffic classes based on match criteria
such as input interface. Packets satisfying the match criteria for a class constitute the traffic for that class.
For more instructions on how to configure traffic queuing, see Configuring Congestion Management.
Traffic Shaping
Regulating the packet flow on the network is also known as traffic shaping. Traffic shaping allows you
to control the speed of traffic leaving an interface. This way, you can match the flow of the traffic to the
speed of the interface receiving the packet.
The Cisco MWR 2941 supports Class-Based Traffic Shaping. Class-Based Traffic Shaping allows you
to regulate the flow of packets leaving an interface on a per-traffic-class basis, matching the packet flow
to the speed of the interface. For more instructions on how to configure traffic shaping, see Configuring
Shaping.

Guide, Cisco IOS Release 15.0S.
