Figure 10-1 Alarm suppression time
The parameter AlarmHoldDuration specifies the alarm suppression time. The SCU will not report the same alarm within the specified time. The default value is 30. A smaller value indicates that the same alarm will be reported more frequently.
Step 5 Properly set AlarmHoldDuration and check whether the fault is rectified.
If the fault is rectified, no further action is required. If the fault persists, contact Huawei technical support engineers.
