Policing and remark: Each packet in classified ingress traffic is assigned an internal priority value, and can
be policed and remarked.
Policing can be performed based on the flow to configure different policies that allocate bandwidth to
classified traffic, the assigned bandwidth policy may be single bucket dual color or dual bucket three color.
The traffic, will be assigned with different color, can be discarded or passed, for the passed packets, add the
remarking action. Remarking uses a new Int-Prio value of lower priority to replace the original higher level
Int-Prio value in the packet. COS and DSCP fields will be modifed according to the new Int-Prio at the egress.
