Manage Network Faults and Notifications in Fault Mode

In Fault mode, Network Director informs you of unexpected, significant events happening in your network. Examples of such events include link up or link down, power supply failure, client authentication failure, detection of an unauthorized access point, and so on.

Network Director receives information about events from its managed devices in the form of SNMP notifications. A single event can often generate multiple SNMP notifications. To simplify management of events, Network Director correlates these notifications, creating high-level alarms of different severity levels for the events. For example, a power supply failure might generate a number of notifications. Network Director correlates these notifications and raises a single power supply failure alarm for the device. Network Director also automatically clears an alarm if it receives notification from the device that the error condition has been resolved.

To tailor Network Director fault management to your organization’s requirements, you can enable or disable the receipt of specific alarms and change the default severity level of alarms.

Alarm Monitors—Alarm Status At-a-Glance

When you enter Fault mode, Network Director displays four alarm monitors in the main window, as shown in Figure 3. These monitors enable you to view at a glance the alarm status of the scope currently selected in the View pane. Alarms are organized by severity, category, and state. By selecting different scopes in the View pane, you can see the alarms being generated from different portions of your network—for example, alarms from all devices in your wireless network, alarms from all devices on a particular floor, or the alarms from a specific device.

Alarm Detailed View—Managing Individual Alarms

From any alarm summary, open the Alarms Detailed View, shown in Figure 4, which provides more information about the alarms. You can view the events that make up an alarm and, for each event that sends attributes, you can view attributes that help describe the event.

In addition, you can acknowledge an alarm, assign an alarm to a person for resolution, annotate an alarm with the actions taken on the alarm, or clear an alarm.

Alarms Pane—Available in Every Mode and Scope

The Alarms pane, shown in Figure 5, is always displayed in the Network Director user interface. It provides a count of the number of critical, major, minor, and info alarms that are active in the entire network. Because this information is displayed in every working mode and scope, you can quickly respond to problems in the network. Click the Expand icon or any of the colored numbers to enter the Fault mode directly.
