Abstract
A generic fault management system and method for maintaining a list of all active alarms on a network generated by managed resources (e.g. network elements) in an SNMP environment. Active alarm tables are stored and maintained in management information bases (MIBs) associated with each of the managed resources and by a distributed management component (such as by an Element Management System (EMS)-MIB and/or a Network Management Station (NMS)-Information Store (IS)). The managed resources of the network experiencing the alarms do not need to conform to a particular alarm content or behaviour. The network can be supported on any SNMP system including both on the managed resources experiencing the alarms, and any distributed management systems monitoring the managed resources. The active alarm tables of the present invention can store any alarm that can be defined using Structure of Management Information (SMI) syntax. The distributed management components can poll the active alarm tables of the NE after a disconnect or after discovery of a new NE to maintain a current active alarm list across the entire network.
