This read-only counter tallies packets that were involved in multiple collisions before being subsequently transmitted successfully, which the MIB notes indicates the network is experiencing moderate to heavy traffic. An admin watches this counter for signs of a congested half-duplex segment or a duplex mismatch driving excessive contention. For example, a high multiple-collision count on this adapter compared to its single-collision count suggests that segment is heavily congested and may benefit from switching to full duplex or segmenting the collision domain.
