Policing and remark:
Each packet in classified ingress traffic is assigned an internal
DSCP value and can be policed and remarked.
Policing can be performed based on DSCP value to configure different policies that
allocate bandwidth to classified traffic. If the traffic exceeds the bandwidth set in the
policy (out of profile), the out of profile traffic can be allowed, discarded or remarked.
Remarking uses a new DSCP value of lower priority to replace the original higher level
DSCP value in the packet; this is also called “marking down”. The following flowchart
describes the operations during policing and remarking.
