Example for Configuring Fault Management

Networking Requirements

As shown in Figure 1, the route between the device and the NMS is reachable. Users want to view alarms generated by the device on the NMS in real time. Users must monitor the LinkDown alarm to ensure the normal interconnection of the device.

Figure 1 Networking for configuring alarm management

Configuration Roadmap

The configuration roadmap is as follows:

Configure the alarm severity to critical, allowing users to monitor LinkDown alarms on the NMS in real time based on the alarm filtering rules.
Configure the alarm reporting delay function to prevent repetitive or flapping alarms from being reported to the NMS.

Procedure

Configure an SNMPv2 user and an NMS host.

<HUAWEI> system-view
[HUAWEI] sysname Switch
[Switch] snmp-agent
[Switch] snmp-agent sys-info version v2c
[Switch] snmp-agent target-host trap address udp-domain 10.1.1.1 params securityname public
[Switch] snmp-agent trap enable feature-name ifnet trap-name linkdown
[Switch] snmp-agent trap enable feature-name ifnet trap-name linkup

Set the severity for the linkDown alarm to critical.

[Switch] alarm
[Switch-alarm] alarm linkDown severity critical

Enable the alarm reporting delay function.

[Switch-alarm] delay-suppression enable
[Switch-alarm] suppression alarm linkdown cause-period 2
[Switch-alarm] suppression alarm linkup clear-period 5
[Switch-alarm] return

Verify the configuration.
