Configuring a Policer

Two-color and tricolor marking policers are configured at the [edit firewall] hierarchy level.

A tricolor marking policer polices traffic on the basis of metering rates, including the CIR, the PIR, their associated burst sizes, and any policing actions configured for the traffic.

To configure tricolor policer marking, include the three-color-policer statement with options at the [edit firewall] hierarchy level:



[edit firewall]
three-color-policer name {


action {


loss-priority high {
then discard;
}


}




single-rate {
(color-aware | color-blind);
committed-information-rate bps;
committed-burst-size bytes;
excess-burst-size bytes;
}




two-rate {
(color-aware | color-blind);
committed-information-rate bps;
committed-burst-size bytes;
peak-information-rate bps;
peak-burst-size bytes;
}


}

For more information about configuring tricolor policer markings, see the JUNOS Policy Framework Configuration Guide and the JUNOS Class of Service Configuration Guide.
