Policing
Traffic policing provides the conformance metering, CoS re-marking and rate limiting
functionality. The conformance metering functionality of the policer determines the
conformance level of the packets (conforming, exceeding, and violating) and performs a
configurable action based on the conformance level. The action configured could be re-
marking
CoS attributes based on conformance level and/or dropping of violating packets (rate-
limit).
Policing can be enabled on the ingress Network Module interface. It can be configured for each
class in the policy-map that is mapped to an ingress interface. If policing is configured and
enabled for a class, it is applied to all the packets that are classified into the class.
The show qos module policy-map command shows the policing configuration (including
accounting status, policing configuration, policing-based remarking configuration and the
corresponding billing and conformance counters) for a class-map within a policy-map.
