Hello, 

We are trying to find an example to redirect the packets those exceed the rate limitation.

For example, a traffic flow carries three part of packets, marked as green, yellow and red. In commonly QoS configured situation, the green packets would pass through without modification, yellow packets will turn down the packet priority, red packets will be dropped. But we want the red packets to turn down the packet priority rather than be dropped, and the red packets should have a lower packet priority than the yellow packets do. 

What's more, the whole rate limitation is required for the traffic flow.

Can we do that?
