DSCP Violate Action Mapping

When a policer is assigned to a class map (flows), use the DSCP Violate Action Mapping screen to specify the action to take when the amount of traffic in the flows exceeds the QoS-specified limits. The portion of the traffic that causes the flow to exceed its QoS limit is referred to as violate action 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 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.
