This is the PmBinState enumeration reporting the lifecycle status of the rolling 24-hour bucket for the current day, still accumulating until the day boundary rolls it into history. It matters on this element because a bin flagged as partial or invalid -- for example one cut short by a manual clear or a device restart mid-interval -- should not be compared directly against a full-length bin's ingress rate-policing totals, or a trend graph built from this table will show a misleading dip that has nothing to do with actual traffic. For instance, a Curr24H bin whose State reads 'partial' right after a line-card reset warns you that its ingress rate-policing counters cover only a fraction of today's still-open 24-hour bucket, not the complete window the other bins in the series represent.
