What is gPortCollisions?
A running counter of collisions detected by this port, with the corresponding remote end incrementing its own gPortRunts counter for the same event; normally under about 5% of received frames. An admin sees this rise sharply when there's cabling trouble, a duplex mismatch, or genuine congestion on the segment.
