Applying the Traffic Control Profiles

Drop profiles allow you to specify queue specific behavior to drop packets based on
WRED profile under congestion. The following is a sample drop profile configuration:
[edit class-of-service drop-profiles]
dp-low {
fill-level 80 drop-probability 0;
fill-level 100 drop-probability 100;
}
dp-high {
fill-level 60 drop-probability 0;
fill-level 80 drop-probability 100;
}
A scheduler map is referenced by traffic control profiles to define queues. The scheduler
map establishes the number of queues over a scheduler node, associating a
forwarding-class with a scheduler. The following is a sample scheduler map configuration:
[edit class-of-service scheduler-maps]
sched-map-ifl0 {
forwarding-class voice scheduler sched-vlan0-qx;
forwarding-class video scheduler sched-vlan0-qx;
forwarding-class data scheduler sched-vlan0-qx;
}
tcp-map-vlan1 {
forwarding-class voice scheduler sched-vlan1-q0;
forwarding-class video scheduler sched-vlan1-qx;
forwarding-class data scheduler sched-vlan1-qx;
}
tcp-map-vlanx {
forwarding-class voice scheduler sched-vlanx-qx;
forwarding-class video scheduler sched-vlanx-qx;
forwarding-class data scheduler sched-vlanx-qx;
}
You can attach the traffic control profiles at various levels of the scheduler hierarchy to
achieve hierarchical class of service. The following is a sample configuration to apply
traffic control profiles:
NOTE: Although a shaping rate can be applied directly to the physical
interface, hierarchical schedulers must use a traffic control profile to hold
this parameter.
