Configuring Rate Limits on Nonqueuing Packet Forwarding Engines

To configure rate limits for nonqueuing Packet Forwarding Engines, include the transmit-rate statement at the [edit class-of-service schedulers scheduler-name] hierarchy level.

Configuring the Schedulers

The following example configures schedulers, forwarding classes, and a scheduler map for a rate-limited interface.

[edit class-of-service schedulers]
scheduler-1 {
transmit-rate percent 20 rate-limit;
priority high;
}
scheduler-2 {
transmit-rate percent 10 rate-limit;
priority strict-high;
}
scheduler-3 {
transmit-rate percent 40;
priority medium-high;
}
scheduler-4 {
transmit-rate percent 30;
priority medium-high;
}

Configuring the Forwarding Classes

[edit class-of-service]
forwarding-classes {
class cp_000 queue-num 0;
class cp_001 queue-num 1;
class cp_010 queue-num 2;
class cp_011 queue-num 3;
class cp_100 queue-num 4;
class cp_101 queue-num 5;
class cp_110 queue-num 6;
class cp_111 queue-num 7;
}

Configuring the Scheduler Map

[edit class-of-service scheduler-maps]
scheduler-map-1 {
forwarding-class cp_000 scheduler scheduler-1;
forwarding-class cp_001 scheduler scheduler-2;
forwarding-class cp_010 scheduler scheduler-3;
forwarding-class cp_011 scheduler scheduler-4;
}

Applying the Scheduler Map to the Interface

[edit interfaces]
ge-1/0/0 {
scheduler-map scheduler-map-1;
unit 0 {
family inet {
address 192.168.1.1/32;
}
}
}
