Configure Traffic Shaping

You can configure the traffic shaping function.

Context

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.

Procedure

Choose QoS > Traffic Shaping > Configure Traffic Shaping in the navigation tree to open the Configure Traffic Shaping page

Table 1 describes the parameters on the Configure Traffic Shaping page.

**Table 1** Configure Traffic Shaping
Parameter	Description
Select Interface	Indicates the interface where traffic shaping needs to be configured. You can select multiple interfaces.
Queues	Indicates the queue. You can select multiple queues.
CIR	Indicates the CIR. NOTE: The value ranges from 0 to 1000000 for the S2750 series. The value ranges from 0 to 1000000 for the S5700 series. The value ranges from 0 to 10000000 for the S6700 series.
PIR	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. NOTE: The value ranges from 64 to 1000000 for the S2750 series. The value ranges from 64 to 1000000 for the S5700 series. The value ranges from 64 to 10000000 for the S6700 series.

Select the interfaces that you want to configure.
Select the queue that you want to configure and set the values of CIR, PIR.
NOTE:
If you do not select the queue, the configurations of the queue are deleted.
Click Apply to complete the configuration.
