To display current and cleared alarms generated on the node, conditions, and events, open the node view and select the Alarms tab (Figure 3-21). The Alarms tabs in network view and card view show network-level alarms and card-level alarms, respectively. Messages with a severity of critical, major, or minor and a status of raised or cleared qualify as alarms. Conditions are messages with a severity of not reported or not alarmed and a status of raised or cleared. Events have a status of transient with a severity of not alarmed. Table 3-8shows the information that displays for each ONS 15327 alarm.
