This read-write object specifies how Elephant Flows (unusually large, sustained traffic flows) are identified on this FlowPoint, choosing between five-tuple identification (source/destination MAC, source/destination IP, IP protocol) or seven-tuple identification which adds source and destination port for TCP/UDP/SCTP traffic. An administrator selects the appropriate tuple granularity depending on whether they need to distinguish flows down to the port level or just by MAC/IP/protocol. For example, choosing seven-tuple identification on a flow point lets the device separately track two different TCP sessions between the same pair of hosts as distinct elephant-flow candidates, which five-tuple identification alone could not do.
