A device detects two stations transmitting simultaneously after the first 64 bytes of the frame have been received. Which interface counter increments?

A late collision occurs when a collision is detected after the first 64 bytes of a frame have been transmitted. This typically happens in half-duplex Ethernet environments where cable lengths exceed the maximum allowed, leading to signal propagation delays that cause a station to believe the medium is clear when another station has already begun transmitting. The collision counter increments for any collision, but a late collision specifically indicates a timing issue. A runt is a frame smaller than 64 bytes, usually caused by a collision, but the counter increments for the frame size, not the collision event itself. CRC (Cyclic Redundancy Check) errors indicate data corruption, not a collision event.
