This read-only Counter32 counts the number of Message Sequence Counter (MSC) mismatches detected, with discontinuities possible at WDS re-initialization. An admin monitors this as a security-integrity metric, since MSC mismatches can indicate replay attacks or corrupted/out-of-order messages in the wireless management protocol. For example, a spike in cwdsiMscMismatchCount coinciding with other anomalies would prompt an admin to investigate a possible replay-attack attempt against the wireless infrastructure.
