Options

single-rate—Named tricolor policer is a single-rate policer.
two-rate—Named tricolor policer is a two-rate policer.
policer-name—Name of a tricolor policer.

Usage Guidelines

Release Information

Statement introduced in JUNOS Release 7.4.

action statement introduced in JUNOS Release 8.2.

Logical systems support introduced in JUNOS Release 9.3.

Description

Configure a tricolor marking policer.

Options

color-aware—Metering varies by preclassification. Metering can increase a packet's assigned PLP, but cannot decrease it.
color-blind—Packet preclassification is ignored. All packets are evaluated by the CBS. If a packet exceeds the CBS, it is evaluated by the EBS.
committed-burst-size bytes—Maximum bytes allowed for incoming packets to be marked green.
committed-information-rate bps—Guaranteed bandwidth under normal line conditions, and the average rate up to which packets are marked green.
excess-burst-size bytes—Maximum bytes allowed for incoming packets. Packets that exceed the EBS are marked red.
peak-burst-size bytes—Maximum bytes allowed for incoming packets to burst above the PIR, but still be marked yellow.
peak-information-rate bps—Maximum achievable rate. Packets that exceed the CIR but are below the PIR are marked yellow. Packets that exceed the PIR are marked red.
single-rate—Marking is based on the CIR, CBS, and the EBS.
two-rate—Marking is based on the CIR and the PIR.
The remaining statements are explained separately.

Usage Guidelines

See Configuring Tricolor Marking.

Required Privilege Level

firewall—To view this statement in the configuration.
