10.2.5 Conditions Tab
The Conditions window displays retrieved fault conditions. A condition is a fault or status detected by
ONS 15310-MA SDH hardware or software. When a condition occurs and continues for a minimum
period, CTC raises a standing condition, which is a flag showing that this particular condition currently
exists on the ONS 15310-MA SDH.
The Conditions window, in contrast with the Alarms 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those that are superseded.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 15310-MA SDH. 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 “Exclude Same Root Cause” 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 15310-MA SDH Troubleshooting Guide for more
information about alarm and condition classifications.
10.2.6 Controlling the Conditions Display
You can control the display of the conditions on the Conditions window. Table 10- 5 shows the actions
you can perform in the window.
