This counter tracks transmitted frames that encountered more than one collision before succeeding. A rising ratio of this counter to the single-collision counter indicates escalating contention on the Ethernet segment -- each additional retry adds latency and, if it keeps climbing toward the max-collisions limit, risks outright frame loss, making this the early-warning counter for a segment sliding from 'busy' to 'saturated.' If multiple collisions per frame become common during peak hours at a site with several LAN devices sharing one switch port through a hub, that pattern would justify moving to a dedicated switched, collision-free connection.
