Traffic policing controls traffic by monitoring the rate of traffic, and discards excess traffic to limit traffic within a proper range and to protect network resources.

When data is sent from a high-speed link to a low-speed link, the bandwidth on the interface of the low-speed link is insufficient. As a result, a large number of packets are discarded. To solve this problem, configure traffic policing for outgoing traffic on the interface of the high-speed link. The interface then discards the packets whose rate exceeds the traffic policing rate so that the outgoing traffic rate is limited within a proper range. You can also configure traffic policing for incoming traffic on the interface of the low-speed link. The interface then discards the received packets whose rate exceeds the traffic policing rate.
