Troubleshooting using network alarms

Incoming alarms from network components are displayed in the dynamic alarm list
and are associated with objects that represent the affected network components.
These alarms determine whether a problem exists.
Alarms raised against a network object are propagated to objects at higher levels in
the managed object hierarchy. They are referred to as correlated alarms. To
troubleshoot using network alarms, start with alarms on the lowest-level object in the
managed object hierarchy. When these alarms are cleared, correlated alarms in the
object hierarchy are cleared automatically.
A problem or alarm can be the result of one or more network problems. To identify
the root cause of a problem, identify the root cause of individual alarms starting with
alarms on the lowest-level managed object. If the affected object is not the cause of
the alarm, the problem may be found on a related, supporting object below the
lowest-level object in the alarm. After the problem is identified and fixed, the faulty
network resource automatically clears the correlated alarms.

You can:
a Use the dynamic alarm list.
i View and monitor alarms. See Procedure
ii Sort alarms in the dynamic alarm list according to time received. See
Procedure 3-1.
b Use the navigation tree to view object alarms and aggregated alarms.
i View alarms from the navigation tree. See Procedure 3-2.
ii Navigate to aggregated or affect alarms from the properties form of the
object. See Procedure 3-2.
Categorize alarms according to the managed object hierarchy and find the alarm
with object type that is lowest in the network object hierarchy. See
Procedure 3-3.
Acknowledge alarms on the affected object and on the related problems. See
Procedure 3-4.
View detailed information about the alarm to determine the probable cause and,
potentially, the root cause. See Procedure 3-5. The following sources of
information are available:
i dynamic alarm list and Alarm Info forms
ii managed object hierarchy table
iii alarm description tables
View the affected object states information. See Procedure 3-5.
