Quality of Service Commands
police srtcm-color
This command defines an enforcer for classified traffic based on a single rate three color meter
(srTCM). Use the no form to remove a policer.
Syntax
[no] police {srtcm-color-blind | srtcm-color-aware}
committed-rate committed-burst excess-burst
conform-action transmit
exceed-action {drop | new-dscp}
violate action {drop | new-dscp}
srtcm-color-blind - Single rate three color meter in color-blind mode.
srtcm-color-aware - Single rate three color meter in color-aware mode.
committed-rate - Committed information rate (CIR) in kilobits per second.
(Range: 0-1000000 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)
excess-burst - Excess burst size (BE) in bytes.
(Range: 0-16000000 at a granularity of 4k bytes)
conform-action - Action to take when rate is within the CIR and BC. (There are enough
tokens in bucket BC to service the packet, packet is set green).
exceed-action - Action to take when rate exceeds the CIR and BC but is within the BE.
(There are enough tokens in bucket BE to service the packet, the packet is set yellow.)
violate-action - Action to take when rate exceeds the BE. (There are not enough tokens in
bucket BE to service the packet, the packet is set red.)
transmit - Transmits without taking any action.
drop - Drops packet as required by exceed-action or violate-action.
new-dscp - Differentiated Service Code Point (DSCP) value. (Range: 0-63)
Default Setting

Command Usage
• You can configure up to 16 policers (i.e., class maps) for ingress ports.
• The committed-rate cannot exceed the configured interface speed, and the committed-burst
and excess-burst cannot exceed 16 Mbytes.
• The srTCM as defined in RFC 2697 meters a traffic stream and processes its packets
according to three traffic parameters – Committed Information Rate (CIR), Committed Burst
Size (BC), and Excess Burst Size (BE).
