This object is the Counter64 equivalent of ciscoScsiTgtPortInCommands, provided per the desc for systems capable of generating command rates fast enough to wrap a 32-bit counter between polling intervals. An admin monitoring a very busy front-end port on a modern all-flash array should use this 64-bit counter to get accurate long-term trending without the misleading resets a 32-bit counter would show under heavy load. This distinction, as with the other high-speed counter pairs in this MIB, only matters once actual command rates approach the 32-bit counter's wraparound threshold within a typical polling window.
