Configuring Priority With Police
You can use the priority with police feature and configure an unconditional priority policer to limit the bandwidth used by
the priority queue and allocate bandwidth or shape other queues. Follow these guidelines when configuring priority with
police:

You cannot configure a policer committed burst size for an unconditional priority policer even though the keyword is
visible in the CLI help. Any configured burst size is ignored when you try to attach the output service policy.

The allowed police rate range is 64000 to 1000000000 bps, even though the range that appears in the CLI help is
8000 to 1000000000. You cannot attach an output service policy with an out-of-range rate.

You cannot configure priority with policing for a traffic class when bandwidth remaining percent is configured for
another class in the same output policy map.

You can configure 1-rate, 2-color policers for output policies with priority. You cannot configure 2-rate, 3-color
policers for output policies.
Beginning in privileged EXEC mode, follow these steps to configure priority with police:
Command Purpose
1. configure terminal Enter global configuration mode.
2. class-map class-map-name Create classes for three egress queues. Enter match conditions
classification for each class.
3. policy-map policy-map-name Create a policy map by entering the policy map name, and enter
policy-map configuration mode.
4. class class-map-name Enter the name of the priority class (created by using the
class-map global configuration command), and enter
policy-map class configuration mode for the priority class.
5. priority Configure this class as the priority class.
Note: Only one unique class map on the switch can be associated
with a priority command.
