The falling threshold value for the context valid in the current view. Just as rbnDhcpIntfThresholdFallingThreshold is the per interface falling threshold, this object is the per context falling threshold. When the sum of the all available DHCP leases in all interfaces of the context valid in the current view reaches the value of this object a falling threshold action of a trap, a log message, or both will be generated. This is a falling threshold, so the evaluation of whether to perform the action occurs upon allocation of a lease from the available pool of leases from any interface within the context. The action of whether to send a trap and/or log message is specified by the values of rbnDhcpCtxThresholdFallingSendTrap and rbnDhcpCtxThresholdFallingLogMessage. If there is no per context rising threshold, the value of this object will be zero and the values of rbnDhcpCtxThresholdFallingSendTrap and rbnDhcpCtxThresholdFallingLogMessage will be false.
