This read-only PerfCounter64 counts frames of 65 to 127 octets received on this link aggregation group as retained in the history bin. It gives an administrator another data point in the historical frame-size distribution of the LAG's inbound traffic, useful for understanding whether small-packet traffic, like VoIP or signaling, dominates a given period. For example, a rise in cmLagHistoryESP65 during a specific week could align with the rollout of a new small-packet monitoring or telemetry application on that link.
