This object specifies the falling threshold for the in-use gauge corresponding to this IP address pool, which must have a value less than or equal to the corresponding instance of ciapPoolThresholdRising. If this value is '0' and the corresponding instance of ciapPoolThresholdRising is '0', then the IP address pool manager does not monitor this IP address pool for threshold crossing events. The value of ciapGlobalThresholdFalling.0 specifies the default value for newly created instances of this object. For more detail, see the description of IP address pool threshold monitoring provided by the descriptive text associated with the MODULE-IDENTITY statement.
