This Gauge32 counts cells or frames dropped on this queue during the current 15-minute period. A rising drop count on a specific queue points to congestion or resource exhaustion on that traffic class, distinct from the RF-layer transport errors tracked elsewhere in the MIB. For example, a customer's video service stuttering while their data traffic seems fine could be explained by a climbing stuAtmStatsCurrMinRxDropped count on the queue serving that video traffic.
