priority police bandwidth

Policing (with drop) is to cap the maximum rate;
Priority/Bandwidth will guarantee minmun rate during the congestion;
Priority/Bandwidth will allocate unused bandwidth when Non-Congestion

If a bandwidth or priority class should not exceed its allocated bandwidth during periods of no congestion, you can combine the priority command with the police command. This configuration imposes a maximum rate that is always active on the class. Choosing to configure a police statement in this configuration depends on the policy's objective.
