Release Information

Statement introduced before 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.

Range: 1500 through 100,000,000,000 bytes

committed-information-rate bps—Guaranteed bandwidth under normal line conditions, and the average rate up to which packets are marked green.

Range: 32,000 through 40,000,000,000 bps

excess-burst-size bytes—Maximum bytes allowed for incoming packets. Packets that exceed the EBS are marked red.

Range: 1500 through 100,000,000,000 bytes

peak-burst-size bytes—Maximum bytes allowed for incoming packets to burst above the PIR, but still be marked yellow.

Range: 1500 through 100,000,000,000 bytes

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.

Range: 32,000 through 40,000,000,000 bps

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.
