mscAtmIfCAUbrPerVcQueueLimitReferenceRate 1.3.6.1.4.1.562.36.2.1.114.3.6.100.1.14

This attribute specifies the shaping rate to be used in computing the tolerable delay for per-VC queues of connections of the UBR service category. The delay is computed as the txQueueLimit divided by the value of this attribute. When the value of this attribute is autoConfigure, an appropriate default is selected based on the card type. It is set to 3685 for low speed cards such as DS1, E1 and IMA, set to 14740 for high speed cards such as JT2, DS3, E3 and OC3, and set to 65511 for high speed ATM IP cards such as 3pDS3Atm2, 3pE3Atm2, 2pOC3SmAtm2 and 2pOC3MmAtm2. For 4pOC12SmIrAtm and 4pOC12SmLrAtm cards, the reference rate is set to 65511 for DS3 and OC3 channels, and set to 262044 for OC12 channels. For Apc- based cards the maximum value is 1416905. For all other cards, the maximum value is 943396. On CQC-based ATM cards, this attribute must be set to the same value for CA NrtVbr, Abr and Ubr components. For the 1pOC12SmLrAtm card, this attribute does not apply since per-VC queueing is not available. For Vpts, this attribute does not apply. Regardless of Vpt service category, standard Vpts always use the AtmIf Ca NrtVbr perVcQueueLimitReferenceRate value as their default. VALUES ( 0 = autoConfigure )
