This read-create INTEGER points to a specific Policer table entry to apply rate-limiting to traffic matched by this class map, with 0 meaning no policer is applied. An admin uses this to cap the bandwidth a particular traffic class can consume, for example restricting bulk file-transfer traffic so it does not starve latency-sensitive classes. For example, an admin wanting to rate-limit a 'BULK-DATA' class map to a defined committed rate would set this pointer to the index of a previously configured Policer entry with that rate.
