This object is the master on-off switch for whether the cefInconsistencyDetection SNMP notification is generated at all for this device. Without this enabled, none of the FIB inconsistency detections recorded in the cefInconsistency table would ever trigger a proactive alert, meaning an admin would have to notice them by polling the table instead. A network team standardizing SNMP trap configuration across their Cisco fleet would enable this on every CEF-capable router so any future FIB corruption anywhere in the network reaches the NMS immediately rather than only being caught during a scheduled audit.
