XAMPLE
This example creates a policy called “rd-policy,” uses the class command to
specify the previously defined “rd-class,” uses the set phb command to
classify the service that incoming packets will receive, and then uses the
police srtcm-color-blind 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.

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.

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: 64-0 kbps at a granularity of 64 kbps or maximum
port speed, whichever is lower)
committed-burst - Committed burst size (BC) in bytes.
(Range: 0-16000000 at a granularity of 4k bytes)
peak-rate - Peak information rate (PIR) in kilobits per second.
(Range: 0-1000000 kbps at a granularity of 64 kbps or maximum
port speed, whichever is lower)
peak-burst - Peak burst size (BP) in bytes.
(Range: 0-16000000 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.)
