This Gauge32 counts cells or frames received with CRC errors on this queue during the current 15-minute period. It flags corruption specific to that traffic queue, which an admin would consider alongside the broader Ethernet CRC counters to see whether the problem is queue-specific or affects the whole link. For example, CRC errors showing up only in stuAtmStatsCurrMinCRCErrors for one queue but not in the general Ethernet CRC counter would suggest a problem isolated to that particular traffic class.
