Alarms

When an alarm condition is found to be true, that level is checked against the current alarm level for the attribute. If there is no change, then no further action is taken.

Figure 15: Alarm Monitoring Algorithm

Only if a new alarm level is detected is there a change in the alarm level reported. This automatically clears alarms when conditions return to the “Normal” level.

If an alarm level changes, the current alarm level is set and propagated up the network hierarchy as needed.

Notifications

All alarms provide indicators for informational purposes that you can check on a routine basis. The NMS is pre-configured with a default set of alarms and notification settings. You can easily customize these settings to reflect your company’s network monitoring methodology.
