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 | new-dscp }
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: 0-40000000 kbps or maximum port speed, whichever is lower)
committed-burst - Committed burst size (BC) in bytes.
(Range: 1000-128000000 bytes)
peak-rate - Peak information rate (PIR) in kilobits per second.
(Range: 0-40000000 kbps or maximum port speed, whichever is lower)
peak-burst - Peak burst size (BP) in bytes. (Range: 1000-128000000 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.
new-dscp - Differentiated Service Code Point (DSCP) value. (Range: 0-63)

Policy Map Class Configuration
Command Usage
◆
You can configure up to 16 policers (i.e., class maps) for ingress ports.
◆
The trTCM as defined in RFC 2698 meters a traffic stream and processes its
packets based on two rates – Committed Information Rate (CIR) and Peak
Information Rate (PIR), and their associated burst sizes - Committed Burst Size
(BC) and Peak Burst Size (BP).
