4.4.1.3 Configuring Alarm Correlation Suppression

Context
Before configuring alarm correlation suppression, enable alarm correlation analysis to analyze
alarm types including root-cause and non-root-cause. For a non-root-cause alarm, the system
marks the sequence number of its root-cause alarm on the non-root-cause alarm. After alarm
correlation suppression is configured, the system filters out non-root-cause alarms and reports
only root-cause alarms to the NMS.
