This PmBinState value reports whether the data in this bin's row can be relied on for reporting, per its DESCRIPTION ('State of the bin.'). For an archived daily bin on this Basic Tx (forwarding) PM instance, anything other than a clean valid state (for example after a clock change or a device restart mid-day) is the flag to exclude that specific day's error and traffic counts from a day-over-day comparison. For example, one archived day marked invalid out of thirty should simply be skipped when computing a monthly average error rate, rather than counted as a zero-error day.
