Figure 3-7 Alarm list 2
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.
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.
Click on the Object Type column to sort the alarms alphabetically according to
object type.
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.
Choose the earlier Lsp Path alarm and acknowledge the alarm.
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.
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.
View alarm information for the affected object. Double-click on the alarm in the
list to view the information in the Alarm Info form.
