14.1.2 C IR a nd 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.
Note: The CIR should be less than the PIR.
Note: The sum of CIRs cannot be greater than or equal to the uplink bandwidth.
