For a three-color policer, configure the committed burst size (CBS) as a number of bytes.
NOTE: When you include the
configuration, you must also include the
statement at the same hierarchy level.
In three-color policing, a committed information rate (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 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.
bytes —Number of bytes. You can specify a value in bytes either as a complete decimal
number or as a decimal number followed by the abbreviation
(1,000,000), or (1,000,000,000).
