rbnDhcpRangeThresholdFallingThreshold
Module: RBN-DHCP-MIB
OID (symbolic): RBN-DHCP-MIB::rbnDhcpRangeThresholdFallingThreshold
OID (numeric): 1.3.6.1.4.1.2352.2.30.1.3.1.9
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: The falling threshold is a value which specifies that any enabled falling threshold events are to be generated when the value of the currently available leases drops to the falling threshold value via an allocation of a lease from the range.
The number of available leases is reported in rbnDhcpRangeThresholdAvailable. A falling threshold event is either a notification or a log message or both. Falling threshold events are enabled if either or both of rbnDhcpRangeThresholdFallingSendTrap and rbnDhcpRangeThresholdFallingLogMessage are true.
Note, this is a falling threshold, so a falling threshold event will only be triggered on a transition of the value of rbnDhcpRangeThresholdAvailable dropping from (rbnDhcpRangeThresholdFallingThreshold+1) to rbnDhcpRangeThresholdFallingThreshold.
What is rbnDhcpRangeThresholdFallingThreshold?
This read-only value (0-196608) sets the level at which a falling-threshold event fires as rbnDhcpRangeThresholdAvailable drops through it on lease allocation within this range, provided rbnDhcpRangeThresholdFallingSendTrap or FallingLogMessage is enabled. An admin sets this as an early-warning line specific to one DHCP subnet range rather than the whole interface.
