For a three-color policer, configure the committed information rate as a number of bits
per second. The committed information rate (CIR) is the guaranteed bandwidth for traffic
arriving at or departing from the interface under normal line conditions.
NOTE: When you include the
configuration, you must also include the
the same hierarchy level.
In three-color policing, a CIR defines the guaranteed bandwidth for traffic arriving at or
departing from the interface under normal line conditions. A flow of traffic at an average
rate that conforms to the CIR is categorized green.
During periods of average traffic rates below the CIR, any unused bandwidth capacity
accumulates up to a maximum amount defined by the committed burst size (CBS). Short
periods of bursting traffic (back-to-back traffic at averages rates that exceed the CIR)
are also categorized as green provided that unused bandwidth capacity is available.
Traffic that exceeds both the CIR and the CBS is considered nonconforming.
Single-rate three-color policers use a dual token bucket algorithm to measure traffic
against a single rate limit. Nonconforming traffic is categorized as yellow or red, based
on the statement included in the policer configuration.
excess-burst-size
Two-rate three-color policers use a dual-rate dual token bucket algorithm to measure
traffic against two rate limits. Nonconforming traffic is categorized as yellow or red based
on the
peak-information-rate
configuration.
—Number of bits per second. You can specify a value in bits per second either as a
bps
complete decimal number or as a decimal number followed by the abbreviation
(1000), (1,000,000), or
