The Related tab button identifies the managed objects that are related to the
object in the alarm and provides useful information for root cause analysis.
Select an object and click on the View Object button. Click on the Faults tab
button, then click on the Alarms on Related Objects or Affected Objects tab
button. This information shows aggregated or propagated alarm information. This
information is not useful for root cause analysis but is helpful in identifying other
affected objects.
Find the object type that is lowest in the network object hierarchy. See the object
hierarchy in Table 3-1.
Through this process, you should find the lowest level managed object related to
the object in the alarm.
Check the States information. This information should point to the root cause of
the alarm. The problem should be found on the related, supporting object below
the lowest level object in the alarm.
If required, check the Administrative State of the supporting port objects. A port
with Administrative State Down does not generate alarms on the port, card, shelf,
LAG, protocols, or sessions, but generates network path and service alarms. If the
Administrative State is Down, change it to Up.
After the problem is fixed, the correlated alarms should automatically clear.
