The NFM-P converts SNMP traps from network routers to events and alarms.
These are then correlated against the managed equipment and configured services
and policies. Alarms are applied against the appropriate equipment and services.
The fault management system provides:
- impact analysis and correlation of alarms to equipment and service-affecting
faults
- updated operational status of equipment, services, and interfaces in
near-real-time from the network router resources
- alarm policy control by network administrators so that the administrators can
determine how to handle individual incoming alarms, and how alarm logs are
created and stored
- operator notes and acknowledgement to track the work undertaken to fix a
problem that caused an alarm
- correlated data in a historical alarm database to provide trend analysis and records
Correlated alarms mean that one alarm may cause fault conditions for many other
objects. When alarms are correlated, the alarms may appear in multiple places. For
example, if an alarm is raised because a port goes down, any services that use that
port would receive indication of the alarm, viewable from the service configuration
form or from the subscriber information form that lists the affected service. All
object information forms contain a faults tab, which lists alarms that affect the object.
All alarms appear on the dynamic alarm list.
