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.'). A completed bin on this Basic Tx (forwarding) PM instance showing anything other than a clean valid state, for example after a clock change, a mid-interval clear, or a device restart, is the flag to exclude that row's error and traffic counts from a trend chart rather than average it in as if it were a normal interval. For example, a bin marked as invalid or partial after a card reboot should be dropped from a week-over-week error-rate comparison rather than plotted alongside clean intervals.
