This read-only StatisticsCntrNumOfBitsType reports the bit width, such as 32 or 64 bits, of this policy statistics counter. It tells the admin how to properly interpret the counter, including when to expect it to wrap around under sustained high traffic. For example, knowing a counter is 32 bits warns an admin monitoring a busy port that the value could wrap relatively quickly and should be polled frequently to avoid missing rollovers.
