Specify DSCP Remark Values for Violate Action IP Packets

If you assign a policer to a class map (which represents a traffic flow), you can specify the
action that must be taken when the amount of traffic in the flow exceeds the specified limits.
This action is referred to as the violate action and applies to the portion of the traffic that
causes the flow to exceed its QoS limit. That portion of the traffic is referred to as the violate
action IP packets.
When this action occurs, the switch remaps the original DSCP value of the violate action IP
packets with a new value based on the information in the DSCP Violate Action Mapping
table. The switch uses the new values to assign resources and the egress queues to these
packets. The switch also physically replaces the original DSCP value in the violate action
packets with the new DSCP value.
This feature changes (remarks) the DSCP tags for incoming traffic switched between trusted
QoS domains.
For example, assume three levels of service—A, B, and C—and that the DSCP incoming
values used to mark these levels are 10, 20, and 30 respectively. If this traffic is forwarded to
