How to configure rate limiting on a physical interface

WAN-side physical interfaces support rate limiting. You can limit the rate of outgoing packets on a WAN-side physical interface by configuring the percentage of the rate of packets against the interface bandwidth. Perform the following configuration:
1. Run the system-view command to enter the system view.
2. (Optional) Run the qos overhead layer { link | physics } command to configure the mode to calculate the packet length during traffic policing or traffic shaping.
By default, the system counts the physical-layer and link-layer compensation information in the packet length during traffic policing or traffic shaping.
3. Run the interface interface-type interface-number command to enter the interface view.
Run the qos lr pct pct-value [ cbs cbs-value ] command to configure the percentage of traffic rate against the interface bandwidth.
By default, the percentage of traffic rate against the interface bandwidth is 100.
