QoS Scheduler Policy Command Reference
576 Quality of Service Guide
cir cir-percent — The cir keyword is optional and when defined the required cir-percent CIR
parameter expresses the policer’s CIR as a percentage of the immediate parent root policer/
arbiter rate or the FP capacity.
Values Percentage ranging from 0.00 to 100.00.
Default 100.00
rate
Syntax rate pir-rate [cir cir-rate]

Description This command specifies the total bandwidth and the within-cir bandwidth allocated to a weighted
scheduler group.
Parameters pir-rate — Specifies PIR rates.
Values kilobits-per-second: 1 to 100000000, max, Kbps
cir cir-rate — Specifies CIR rates.
Values 0 to 100000000, max, Kbps

Context config>qos>port-scheduler-policy
Description This command configures an explicit within-cir bandwidth limit and a total bandwidth limit for each
port scheduler’s priority level. To understand how to set the level rate and CIR parameters, a basic
understanding of the port level scheduler bandwidth allocation mechanism is required. The port
scheduler takes all available bandwidth for the port or channel (after the max-rate and any port egress-
rate limits have been accounted for) and offers it to each of the eight priority levels twice.
