The value of this object indicates the PIR rate for traffic that has been classified as Standard traffic. This attribute reflects a best effort peak data rate. If rcCosProfileStandardPirUnits is set to 1, this value may not exceed 15.If rcCosProfileStandardPirUnits is set to 3, this value may not exceed 200.Traffic that has been colored yellow as a result of exceeding a Gold or Silver CIR and exceeds this data rate is discarded. Any traffic classified as Standard, a NNSC classification that is analogous to DSCP Standard, ToS Routine, or 802.1p user priority 0, that exceeds this data rate will be discarded. Traffic that has been classified as Premium, and traffic hat has been classified as Gold or Silver that has not exceeded their CIR, will not be discarded if the data rate exceeds this PIR. That traffic may, however, force this PIR to a value less than or equal than zero.
