The following procedure describes how to troubleshoot the problem.
Procedure 3-9 To troubleshoot an underlying port state problem
1 The First Time Detected column shows that 16 alarms are raised at approximately
the same time, which is a good indication that these alarms may be correlated.
2 Click on the Object Type column to sort the alarms alphabetically according to
object type.
3 Scroll through the dynamic alarm list and find the object type that is lowest in the
network object hierarchy, as listed in Table 3-1.
In this example, the lowest-level object type in the alarm list is Lsp Path in the
Path/Routing Management domain. There are two Lsp Path Down alarms. One was
raised later than the other.
4 Choose the earlier Lsp Path alarm and acknowledge the alarm.
5 Choose the alarms related to this affected object and acknowledge those alarms.
In this case, the only alarm listed under Related Problems is the dynamic Lsp Down
alarm.
6 View alarm information for the affected object. Double-click on the alarm in the
list to view the information in the Alarm Info form.
Note — The list contains an Lsp Down alarm and an Lsp Path Down
alarm. Approximately one half hour later, a second Lsp Down alarm and
a second Lsp Path Down alarm were raised for a total of 18 alarms.
Note — Alarm reporting latency can vary depending on network
conditions. Therefore, the First Time Detected stamp is not a reliable
indication of the exact time an event occurred and should be used only
as an aid in troubleshooting.
