The Peak Information Rate (PIR) is the maximum bandwidth allowed for the incoming traffic flow on a port when there is no network congestion. The CIR and PIR should be set for all ports that use the same uplink bandwidth. If the CIR is reached, packets are sent at the rate up to the PIR. When network congestion occurs, packets through the ingress port exceeding the CIR will be marked for drop. " The CIR should be less than the PIR.

Bandwidth Control
This chapter shows you how you can cap the maximum bandwidth using the
Bandwidth
Control
screen.
12.1
Bandwidth Control Overview
Bandwidth control means defining a maximum allowable bandwidth for incoming and/or out-
going traffic flows on a port.
12.1.1
CIR and PIR
The Committed Information Rate (CIR) is the guaranteed bandwidth for the incoming traffic
flow on a port. The Peak Information Rate (PIR) is the maximum bandwidth allowed for the
incoming traffic flow on a port when there is no network congestion.
The CIR and PIR should be set for all ports that use the same uplink bandwidth. If the CIR is
reached, packets are sent at the rate up to the PIR. When network congestion occurs, packets
through the ingress port exceeding the CIR will be marked for drop.
The CIR should be less than the PIR.
The sum of CIRs cannot be greater than or equal to the uplink bandwidth.
