shaping in an interface queue. Otherwise, traffic shaping fails. For example, traffic of lower
priorities preempts the bandwidth of traffic of higher priorities.
Pre-configuration Tasks
Before configuring traffic shaping, complete the following tasks:
l Setting link layer attributes of interfaces to ensure normal operation of the interfaces
l Assigning IP addresses to the interfaces and configuring routing protocols to ensure that
routes are reachable
Data Preparation
To configure traffic shaping, you need the following data.
No. Data
1 Rate for traffic shaping on an interface
2 (Optional) Rate for traffic shaping in an interface queue, including the CIR and PIR
3 Interface on which traffic shaping is applied or index of the queue
2.4.2 Configuring Traffic Shaping on an Interface
You can configure traffic shaping on an interface to limit the rate of data sent by the interface.
Context
To perform traffic shaping for all the downstream packets on an interface, perform this
procedure.
If you need to set the same traffic shaping rate on multiple interfaces, you can perform the
configuration on the port group to reduce the workload.
Do as follows on the S7700 where traffic shaping needs to be configured.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface interface-type interface-number
The interface view is displayed.
Or run the port-group port-group-name command to display the port group view.
