Specifies the exact number of media collisions, from 1 to 16, that a given collision-histogram cell is counting the frequency of, for one interface. Together with dot3CollFrequencies, it lets an admin build a full histogram showing how often frames needed 1, 2, 3...16 collisions before transmitting successfully. For example, a row with dot3CollCount 3 and a high dot3CollFrequencies value indicates that 3-collision transmissions are unusually common on that interface, a sign of heavy contention.
