Notification Format

For each alarm and event notification, the following information is provided (see Table 14-1).

Table 14-1 Notification Format 

Field	Description
Title	The notification title is generally picked up from an event property file defined in the NMS.
MIB Name	The MIB Name is the name of the notification as defined in the management information base (MIB). In some cases, if the event is specific only to the NMS, this field is not relevant. You can define multiple events in WCS from the same trap based on the values of the variables present in the trap. In such cases, multiple subentries appear with the same MIB Name. In addition, this field displays the value of the variable that caused WCS to generate this event.
WCS Message	The WCS Message is a text string that reflects the message displayed in the WCS alarm or event browser associated with this event. Numbers such as "{0}" reflect internal WCS variables that typically are retrieved from variables in the trap. However, the order of the variables as they appear in the trap cannot be derived from the numbers.
Symptoms	This field displays the symptoms associated with this event.
WCS Severity	This field displays the severity assigned to this event in WCS.
Probable Causes	This field lists the probable causes of the notification.
Recommended Actions	This field lists any actions recommended for the administrator managing the wireless network.
