This read-write object holds the lower 32 bits of the rate threshold above which a flow is declared an Elephant Flow on this FlowPoint, and if cmFlowPointEfEnabled is on but this is set to 0, it behaves the same as disabling elephant-flow detection altogether. An administrator tunes this threshold to control how large a sustained flow must be before the device flags it for special handling. For example, lowering this threshold on a flow point makes the device more sensitive, flagging moderately large flows as elephant flows that a higher threshold would have ignored.
