2.6.2 Example for Configuring Traffic Policing Based on a Traffic
Classifier
The Switch provides different bandwidth by configuring traffic policing based on a traffic
classifier and setting different CAR parameters.
Networking Requirements
The Switch is connected to the router by using GE 0/0/2; enterprise users can access the network
by using the Switch and the router. In

On the Switch, traffic policing needs to be performed on packets of different services to limit
traffic within a proper range and ensure bandwidth of each service.
DSCP priorities carried in service packets sent from the user side cannot be trusted and services
require different QoS in practice. Therefore, you need to re-mark DSCP priorities of different
service packets on the Switch so that the downstream router can process packets based on
priorities.
The requirements are as follows:
