A policy-map defines a set of rules that prioritize network traffic, ensuring critical data isn't delayed by less important packets. Each policy-map aggregates multiple class-maps, which are associated with specific match criteria such as VLAN, DSCP, or IP ACLs. Actions — including DSCP marking, traffic-class assignment, and policing — can be applied to each policy-map and class-map pair. This allows specific QoS actions to be executed on every incoming packet based on defined parameters.
