When the number of used addresses in an IP local pool
is equal or exceeds this threshold value, a
ciscoIpLocalPoolInUseAddrNoti notification will be generated.
Once this notification is generated, it will be disarmed and it
will not be generated again until the number of used address
falls below the value indicated by
cIpLocalPoolStatInUseAddrThldLo.
The value of this object should never be smaller than the value
of cIpLocalPoolStatInUseAddrThldLo.
