command to limit the average bandwidth to 100,000 Kbps, the committed burst
rate to 4000 bytes, the excess burst rate to 6000 bytes, to remark any packets
exceeding the committed burst size, and to drop any packets exceeding the excess
burst size.

police trtcm-color This command defines an enforcer for classified traffic based on a two rate three
color meter (trTCM). Use the no form to remove a policer.
Syntax
[no] police {trtcm-color-blind | trtcm-color-aware}
committed-rate committed-burst peak-rate peak-burst
conform-action transmit
exceed-action {drop | new-dscp}
violate action {drop | new-dscp}
trtcm-color-blind - Two rate three color meter in color-blind mode.
trtcm-color-aware - Two rate three color meter in color-aware mode.
committed-rate
- Committed information rate (CIR) in kilobits per second.
(Range: 64-1000000 kbps at a granularity of 64 kbps or maximum port
speed, whichever is lower)
committed-burst
- Committed burst size (BC) in bytes.
(Range: 4000-16000000 at a granularity of 4k bytes)
peak-rate
- Peak information rate (PIR) in kilobits per second.
(Range: 64-1000000 kbps at a granularity of 64 kbps or maximum port
speed, whichever is lower)
peak-burst
- Peak burst size (BP) in bytes.
(Range: 4000-16000000 at a granularity of 4k bytes)
conform-action - Action to take when rate is within the CIR and BP. (Packet
size does not exceed BP and there are enough tokens in bucket BC to
service the packet, the packet is set green.)
exceed-action - Action to take when rate exceeds the CIR but is within the
PIR. (Packet size exceeds BC but there are enough tokens in bucket BP to
service the packet, the packet is set yellow.)
violate-action - Action to take when rate exceeds the PIR. (There are not
enough tokens in bucket BP to service the packet, the packet is set red.)
drop - Drops packet as required by exceed-action or violate-action.
transmit - Transmits without taking any action.
