This read-only PmBinState enumeration reports whether the data currently held in this table's currently-accumulating, short-interval bin in this IGMP snooping/proxy PM table is complete and can be trusted for reporting. A non-normal state tells an admin to discount the counters in this bin — for instance after a reboot or a mid-interval clear left it only partially filled — rather than mistaking a low reading for genuinely low traffic, since it is the metadata field for this table's currently-accumulating, short-interval bin in this IGMP snooping/proxy PM table. For this table's currently-accumulating, short-interval bin in this IGMP snooping/proxy PM table, a value of 1 might mean the bin filled its full window normally, while a value like 2 would tell an admin the data was cut short — for example by a reboot mid-interval — and should be treated as incomplete.
