Object
notification
This notification signifies that the number
of available IP addresses for a particular scope
has fallen below the value of
cnrNotifDHCPScopeFreeAddrLow for that scope.
This notification signals a shortage of addresses.
The shortage will continue until the number of free
addresses has reached or exceeded the number
specified by the cnrNotifDHCPScopeFreeAddrHigh object.
This notification will only be generated when the
shortages of IP addresses in first encountered.
If the threshold type is scope or subnet, then the value is
the primary or secondary subnet number, and if the type is
selection-tag, then the value is the selection tag list.
