Hierarchy Level

Release Information

Statement introduced in Junos OS Release 7.4.

Support at the [edit dynamic-profiles ... single-rate] and [edit dynamic-profiles ... two-rate] hierarchy levels introduced in Junos OS Release 11.4.

Description

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 committed-information-rate statement in the configuration, you must also include the committed-burst-size statement at 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 excess-burst-size statement included in the policer configuration.

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 and peak-burst-rate statements included in the policer configuration.

Options

bps—Number of bits per second. You can specify a value in bits per second either as a complete decimal number or as a decimal number followed by the abbreviation k (1000), m (1,000,000), or g (1,000,000,000).

Range:

  • 1500 through 100,000,000,000  bps on EX, M, and T Series routers

  • 1500 through 18,446,744,073,709,551,615  bps on Mx Series routers
