Hierarchy Level

Release Information

Statement introduced in Junos OS Release 7.4.

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

Statement introduced in Junos OS Release 12.3R2 for EX Series switches.

Description

For a two-rate three-color policer, configure the peak information rate (PIR) as a number of bits per second. The PIR is the maximum rate for traffic arriving at or departing from the interface under peak line conditions. Traffic that exceeds the committed information rate (CIR) and the committed burst size (CBS) is metered to the PIR.

Note: When you include the peak-information-rate statement in the configuration, you must also include the committed-information-rate and peak-burst-size statements at the same hierarchy level.

Two-rate three-color policers use a dual-rate dual token bucket algorithm to measure traffic against two rate limits.

  • A traffic flow is categorized green if it conforms to both the CIR and the CBS-bounded accumulation of available committed bandwidth capacity.
  • A traffic flow is categorized yellow if exceeds the CIR and CBS but conforms to the PIR. Packets in a yellow flow are marked with medium-high packet loss priority (PLP) and then passed through the interface.
  • A traffic flow is categorized red if exceeds the PIR and the PBS-bounded accumulation of available peak bandwidth capacity. Packets in a red traffic flow are marked with high PLP and then either passed through the interface or optionally discarded.

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

Required Privilege Level
