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.'). Because this is the still-filling interval on this Basic Tx (forwarding) PM instance, expect this to read as an in-progress or partial state until the interval closes, rather than the settled valid state a completed History row would show. For example, this reading as 'partial' at 09:07 for a bin that started at 09:00 is normal and not a fault; it only becomes a concern if it still reads partial well after the configured Duration has elapsed.
