5.1 Fault Management Overview

FM is used to enhance the network reliability.
FM monitors and reports the existing and potential faults for users to understand the running
status of the system. The FM functions are as follows:
l
l

5.2 FM Supported by the NE5000E

FM involves the alarm suppression, alarm filtering, alarm query, alarm clearing, and alarm
simulation functions, which help users rapidly and accurately complete the configuration.
With the network growth, the network becomes increasingly complex, and thus more network
configurations and applications are deployed. When a certain module on a device fails, multiple
alarms may be generated on one or more devices. The devices and NMS hosts, however, are
incapable of processing all alarms, causing alarm lost during the alarm transmission. As a result,
some alarms that users are concerned about cannot be displayed, which hinders network
management. FM is used to dynamically manage and report alarms generated on devices in a
centralized manner.
The NE5000E currently supports the following FM functions:

5.3 Configuring FM

Users can configure FM on a device to use the alarm filtering, alarm delivery, and alarm
suppression functions.

Configuration Procedures
Choose one or more configuration tasks (excluding "Checking the Configuration") as needed.
Issue 01 (2011-10-15)
FM collects statistics about faults accurately and in real time.
FM informs users of the faults after further analyzing the collected fault statistics.
FM improves user experience by filtering out invalid alarms and presenting users with only
the alarms that they are concerned about.
Filtering out repeated alarms, service intermittency alarms, and flapping alarms
Filtering out the alarms that users are not concerned about
Displaying alarm configurations, active alarms, previously-generated alarms, and statistics
about alarms to present details about the network faults
Clearing previously-generated alarms to simplify the alarm display
Simulating and reporting alarms to check whether the terminal and NMS host are correctly
configured and whether the management link is reachable
Installing the router and powering it on properly
Completing the alarm definition on the NE5000E
