Traffic Shaping

Traffic Shaping

Traffic shaping is also called queue shaping and interface shaping. The queue shaping technology limits traffic in a defined range by setting the shaping rate of packets of the entire queue. This prevents downstream traffic congestion.

View Traffic Shaping

You can view traffic shaping information about an interface.


  • The switch supports queue shaping and interface shaping.
  • You can select an interface to view the traffic shaping information. You can select only one interface.


  1. Choose QoS > Traffic Shaping > View Traffic Shaping in the navigation tree to access the View Traffic Shaping page.
  2. Select any interface.
  3. The traffic shaping information about the interface is displayed, as shown in Figure 2-175.

Configure Traffic Shaping

You can configure the traffic shaping function.


When the rate of an interface on a downstream device is smaller than the rate of an interface on an upstream device or the burst traffic occurs, traffic congestion may occur on the interface of the downstream device. In this case, you can configure traffic shaping on the interface of the upstream device in the outbound direction so that traffic is sent at an even rate and the congestion problem of the downstream device is solved.


  1. Choose QoS > Traffic Shaping > Configure Traffic Shaping in the navigation tree to open the Configure Traffic Shaping page, as shown in Figure 2-176.

    Figure 2-176  Configure Traffic Shaping

    Table 2-101 describes the parameters on the Configure Traffic Shaping page.

    Table 2-101  Configure Traffic Shaping



    Select Interface

    Indicates the interface where traffic shaping needs to be configured. You can select multiple interfaces.


    Indicates the queue. You can select multiple queues.


    Indicates the CIR.


    Indicates the PIR of an interface. The default value is the bandwidth of the interface and the value cannot be smaller than the value of the CIR.

  2. Select the interfaces that you want to configure.
  3. Select the queue that you want to configure and set the values of CIR, PIR.


    If you do not select the queue, the configurations of the queue are deleted.

  4. Click Apply to complete the configuration.
