Release Information

Statement introduced in JUNOS Release 7.4.

The action and single-rate statements added in JUNOS Release 8.2.


For M320, MX Series, and T Series routers with Enhanced II Flexible PIC Concentrators (FPCs), configure a tricolor marking policer.


single-rate—Marking is based on the CIR.

two-rate—Marking is based on the CIR and the PIR.

color-aware—Metering varies by preclassification. Metering can increase a packet’s assigned PLP, but cannot decrease it.

color-blind—All packets are evaluated by the CIR or CBS. If a packet exceeds the CIR or CBS, it is evaluated by the PIR or EBS.

committed-burst-size bytes—Guaranteed deliverable burst.

Range: 1500 through 100,000,000,000

committed-information-rate bps—Guaranteed bandwidth under normal line conditions.

Range: 1500 through 100,000,000,000

excess-burst-size bytes—Maximum allowable excess burst.

Range: 1500 through 100,000,000,000

peak-burst-size bytes—Maximum allowable burst.

Range: 1500 through 100,000,000,000

peak-information-rate bps—Maximum achievable rate.

Range: 1500 through 100,000,000,000

The remaining statements are explained separately.
