This object is used to enable or disable the GGSN behavior of sending CAC failure notification to SLB, or session failure notification to SLB. If this object is set to cacFailure(1), then this object is required to enable the feature in the dispatched mode of operation of SLB. If this object is set to sessionDeletion(2), then GGSN will send delete notification message to SLB when the last PDP associated with a IMSI is deleted. This object is deprecated by cGgsnSlbNotifyCacFailure and cGgsnSlbNotifySessionDeletion.
