Above-CIR Priority Level Parameters
The above-cir parameters define which port priority level the queue or scheduler should be
associated with when receiving bandwidth for the queue’s or scheduler’s above-cir offered
load. The above-cir offered load is the amount of bandwidth the queue or scheduler could use
that is equal to or less than its defined PIR value (based on the queue or schedulers rate
command) less any bandwidth that was given to the queue or scheduler during the above-cir
scheduler pass. The parameters that control above-cir bandwidth allocation are the port-
parent commands level and weight keywords. The level keyword defines the port priority
level that the scheduler or queue uses to receive bandwidth for its above-cir offered load. The
weight is used when multiple queues or schedulers exist at the same port priority level for
above-cir bandwidth. The weight value defines the relative ratio that is used to distribute
bandwidth at the priority level when more above-cir offered load exists than the port priority
level has bandwidth.
