Description: Collisions detected.
What is cmLagHistoryESC?
This read-only PerfCounter64 counts collisions detected on this link aggregation group as retained in the history bin, the archived counterpart to cmLagStatsESC. Since collisions indicate a legacy half-duplex condition, a past bin showing a nonzero count helps an administrator confirm when a duplex mismatch first appeared on one of the LAG's member links. For example, correlating the first bin with a nonzero cmLagHistoryESC against a change log can pinpoint which cabling or NIC swap introduced the mismatch.
