acSwitchBuffCfgOversubRate 1.3.6.1.4.1.2785.2.10.2.1.2

A percentage indicating how much the system should oversubscribe buffers to queues. By oversubscribing buffers to queues, a statistical gain can be achieved with respect to system throughput. For example, to oversubscribe buffer utilization by 50%, set acSwitchBuffCfgOversubRate to 50. This means that if some queues encounter bursty traffic, they will be less likely to drop data. Using oversubscription involves risking that all traffic flows do not burst at the same time. If this were to happen, some high priority traffic could be dropped in favor of lower priority traffic. Since this may be undesirable, the default value for this object is 0 (indicating a zero percent oversubscription rate). A setting of 0 implies the total number of buffer credits in the system equals the total number of physical buffers.
