Release Information

Statement introduced in JUNOS Release 7.4.

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

Description

For T-series and M320 platforms with Enhanced II Flexible PIC Concentrators (FPCs), configure a tricolor marking policer.

Options

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.
committed-information-rate bps—Guaranteed bandwidth under normal line conditions.
excess-burst-size bytes—Maximum allowable excess burst.
peak-burst-size bytes—Maximum allowable burst.
peak-information-rate bps—Maximum achievable rate.
The remaining statements are explained separately.

Usage Guidelines

See Configuring a Tricolor Marking Policer.

Required Privilege Level
