20.3.5 Conditions Tab

The Conditions window displays retrieved fault conditions. A condition is a fault or status detected by
ONS 15454 hardware or software. When a condition occurs and continues for a minimum period, CTC
raises a condition, which is a flag showing that this particular condition currently exists on the
ONS 15454. See the
The Conditions window shows all conditions that occur, including those that are superseded. For
instance, if a network problem causes two alarms, such as LOF and LOS, CTC shows both the LOF and
LOS conditions in this window (even though LOS supersedes LOF). Having all conditions visible can
be helpful when troubleshooting the ONS 15454. If you want to retrieve conditions that obey a
root-cause hierarchy (that is, LOS supersedes and replaces LOF), you can exclude the same root causes
by checking a check box in the window.
Fault conditions include reported alarms and Not Reported or Not Alarmed conditions. Refer to the
trouble notifications information in the Cisco ONS 15454 SONET and DWDM Troubleshooting Guide
for more information about alarm and condition classifications.

20.3.6.1 Retrieving and Displaying Conditions

The current set of all existing conditions maintained by the alarm manager can be seen when you click
the Retrieve button. The set of conditions retrieved is relative to the view. For example, if you click the
button while displaying the node view, node-specific conditions are displayed. If you click the button
while displaying the network view, all conditions for the network (including ONS 15454 nodes and other
connected nodes) are displayed, and the card view shows only card-specific conditions.
You can also set a node to display conditions using the time zone where the node is located, rather than
the time zone of the PC where they are being viewed. See the
Time Zone" section on page 20-2
