You can configure FM on a device to use the alarm filtering, alarm delivery, and alarm suppression functions.
As the network scale expands, the network becomes increasingly complex, and therefore more network configurations and applications are deployed. If a module on a device fails, multiple alarms may be generated on one or more devices. The devices and NMS, however, may not be able to process all alarms, causing alarm loss during the alarm transmission. If some alarms that users are concerned about cannot be obtained, network management becomes difficult. FM dynamically manages and reports alarms generated on devices in a centralized manner.
The NetEngine 8000 F supports the following FM functions:
Filters out repeated alarms, intermittent alarms, and flapping alarms.
Filters out the alarms that users are not concerned about.
Displays alarm configurations, active alarms, historical alarms, and alarm statistics to present details about network faults.
Clears historical alarms to simplify the alarm display.
Simulates and reports alarms to check whether the terminal and NMS host are correctly configured and whether the management link is reachable.
Before configuring FM, complete the following tasks:
Install the router and power it on properly.
Complete the alarm definition on the NetEngine 8000 F.
