About This Chapter

This chapter describes the basic concepts of class-based quality of service (QoS), including the

traffic classifier, traffic behavior, traffic policy, and priority mapping. It also describes

configuration methods and provides configuration examples of the traffic policy based on

complex traffic classification and priority mapping based on simple traffic classification.

1.1 Introduction to Class-based QoS

Class-based QoS is used to classify packets sharing common features into one class and provide

the same QoS service for traffic of the same type by matching packets with certain rules. In this

manner, differentiated services are provided.

1.2 Class-based QoS Features Supported by the S3700HI

The S3700 supports simple traffic classification, complex traffic classification, and priority

mapping.

1.3 Configuring Priority Mapping Based on Simple Traffic Classification

Priority mapping based on simple traffic classification maps packet priorities to PHBs and colors

to provide differentiated services.

1.4 Creating a Traffic Policy Based on Complex Traffic Classification

After the traffic policy based on complex traffic classification is configured, the S3700 classifies

packets according to the priority of packets and quintuple information. Then the S3700 takes

different traffic actions for packets matching classification conditions, such as permit/deny, re-

marking, and redirection.

1.5 Configuring a Traffic Policy by Using Simplified QoS Commands

By using simplified QoS commands, you can configure traffic monitoring, traffic statistics,

traffic redirection, traffic re-marking, and traffic mirroring. Compared with common QoS

commands, simplified QoS commands make the configuration procedures easier because you

do not need to create traffic classifiers, traffic behaviors, and traffic policies independently.

1.6 Maintaining Class-based QoS

If the traffic statistics function is enabled, you can view and clear the flow-based traffic statistics.

1.7 Configuration Examples

This section provides several configuration examples of class-based QoS.
