The rising threshold is a value which specifies that any enabled rising threshold events are to be generated when the value of the currently available leases reaches the rising threshold value via a returning of a lease to the pool. The number of available leases is reported in rbnDhcpIntfThresholdAvailable. A rising threshold event is either a notification or a log message or both. Rising threshold events are enabled if either or both of rbnDhcpIntfThresholdRisingSendTrap and rbnDhcpIntfThresholdRisingLogMessage are true. Note, this is a rising threshold, so a rising threshold event will only be triggered on a transition of the value of rbnDhcpIntfThresholdAvailable increasing from (rbnDhcpIntfThresholdRisingThreshold-1) to rbnDhcpIntfThresholdRisingThreshold.
