This read-create INTEGER is the eighth and final tuple-pointer slot available in an ACE, completing the maximum set of combinable match conditions for a single rule. An admin who needs this many simultaneous match conditions in one ACE is building close to the most granular classification rule the device's QoS engine supports. For example, if an admin's rule design calls for eight distinct match fields to isolate one very specific traffic flow, this eighth slot would hold the last of those Tuple pointers, with no room to add a ninth condition to the same ACE.
