Chapter 9 Managing Faults
Where Is the Fault?
9.5.1 Sources of Information
Fault management receives and processes information from the following sources:
• Autonomous reports of failures from NEs
• Trouble reports from customers and peer systems
• Results of diagnostics, exercises and audits from NEs
• Impairment indications from performance management
• Network configuration data from configuration management.
Cisco MGM constantly updates the alarm status of the network based on the alarm and event
notifications sent by the monitored NEs and generated by the EMS itself. It performs alarm
synchronization with the NE each time the connection to the NE is established or re-established and the
NE is in service.
9.5.2 Identifying and Monitoring Alarms
There are a number of options available to identify and monitor alarms on the entire domain or in a group
of NEs:
• In the Domain Explorer Hierarchy pane, select the management domain node or a group node. If it
shows a critical, major, minor, or warning alarm icon, it means that one or more NEs within the
management domain or group are experiencing an alarm.
• Select the management domain node or group node and choose Fault > Alarm Browser (or
right-click the node and choose Alarm Browser in the popup menu). This opens the Alarm Browser
window, which shows all the NEs in the management domain or group that are experiencing a
critical, major, minor, or warning alarm. See Figure 9-3.
• Click an alarm count box in the Dashboard, the Alarm Browser appears, prefiltered for the selected
alarm severity.
• Click the Open Alarm Browser tool from the Dashboard to show Cisco MGM specific EMS alarms
in the Alarm Browser.
• Click the Open Cisco MGM EMS Alarm Browser tool from the Dashboard to show alarms on
Cisco MGM in the Alarm Browser.
To identify and monitor alarms on specific NEs:
Step 1 Select an in-service NE in the Domain Explorer Hierarchy pane that shows an alarm icon.
Step 2 Choose Fault > Alarm Browser, or right-click and choose Alarm Browser in the popup menu.
Note Alarms relating to PM collection indicate that the load on the system is high. Reduce the load on the
system before proceeding.
