S12700 V200R010C00 Configuration Guide - QoS

This document describes the configurations of QoS functions, including MQC, priority mapping, traffic policing, traffic shaping, interface-based rate limiting, congestion avoidance, congestion management, packet filtering, redirection, traffic statistics, ACL-based simplified traffic policy, and HQoS.

Configuring Hierarchical Traffic Policing

Configuring Hierarchical Traffic Policing

Context

The device supports hierarchical traffic policing. After the system uses MQC to implement traffic policing (level-1 CAR) for service flows matching a traffic classifier in a traffic policy, the system aggregates all the service flows matching the traffic classifiers associated with the level-1 CAR in the same traffic policy and performs traffic policing (level-2 CAR) for the aggregated flow. Hierarchical traffic policing implements statistical multiplexing of traffic and provides fine-grained service control. For details about level-1 CAR, see Configuring MQC to Implement Traffic Policing.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    qos car car-name cir cir-value [ cbs cbs-value [ pbs pbs-value ] | pir pir-value [ cbs cbs-value pbs pbs-value ] ]

    A QoS CAR profile is created and CAR parameters are configured.

  3. Run:

    traffic behavior behavior-name

    The traffic behavior view is displayed.

  4. Run:

    car car-name share

    The aggregated CAR action is configured.

    NOTE:
    • The ET1D2X48SEC0, SA series, and SC series cards do not support aggregated CAR.

    • The traffic policy defining the aggregated CAR action can only be used in the inbound direction.

    • After aggregated CAR is configured, all the rules in the traffic classifiers bound to the same traffic behavior share the CAR index. The system aggregates all the flows matching these traffic classifiers and uses CAR to limit the rate of the flows. If the traffic classifiers define both Layer 2 and Layer 3 information, the aggregated CAR configuration is invalid.
