Information About Mutation Mapping

Mutation mapping is a method of modifying a quality of service (QoS) field in all packets on an interface.
On ingress, mutation mapping occurs before traffic classification and all other actions. On egress, mutation
mapping occurs after traffic classification and before the other actions. You can apply mutation mapping to
the class of service (CoS), Differentiated Service Code Point (DSCP), IP precedence packet fields, or to the
internal field discard class.
You cannot configure system-defined mutation maps. You can only configure those maps that modify the
same source and destination variable.
You use a hierarchical policy map to configure mutation mapping. In the mutation mapping policy map, you
specify the field to mutate and the policy map to apply with the mutation.
