Context

Figure 1 Alarm status relationship

Based on the alarm acknowledgment and clearance status, alarms are classified into:

• Current alarms: include uncleared and unacknowledged alarms, acknowledged and uncleared alarms, and unacknowledged and cleared alarms. O&M personnel can monitor and handle alarms that they are concerned about on the Current Alarms page.
• Historical alarms: include alarms that have been cleared and acknowledged. Historical alarms are a data source for network performance optimization. O&M personnel can query and collect statistics on alarms.

Procedure

1. Choose Device Management > Alarms Management > Current Alarms from the main menu.
2. On the Current Alarms page, you can perform the following operations:

   Operation	Scenario	Operation
   Viewing alarm details	Obtains key alarm information, including alarm names, repair recommendations, and location information, to facilitate fault diagnosis and troubleshooting.	In the alarm list, select an alarm and click below the list to view the alarm details.
   Manually acknowledging an alarm	An acknowledged alarm indicates that the alarm is being handled by the user whose name is displayed in the Acknowledged By column. When the alarm is acknowledged, the alarm status is changed from unacknowledged to acknowledged.	You can select one or more alarms and click Acknowledge above the alarm list. You can also click in the Operation column of the row that contains the desired alarm. After you have acknowledged an alarm, the username is displayed in the Acknowledged By column.
   Specify a handler	Assigns the O&M personnel to handle an alarm.	In the alarm list, select an alarm and click in the Operation column to select a user to handle the alarm. After the alarm is acknowledged, the username is displayed in the Handler column.
   Manually clearing alarms	Some alarms cannot be automatically cleared. Therefore, you need to clear the alarms manually after the faults are rectified.	You can select one or more alarms and click Clear above the alarm list. You can also click in the Operation column of the row that contains the desired alarm. If an alarm has been acknowledged after being cleared, the alarm will be moved to the Historical Alarms page. If an alarm has not been acknowledged after being cleared, it is retained on the Current Alarms page, with a green background. NOTE: The cleared alarm cannot be restored. Exercise caution when performing the operation.
   Recording maintenance experience	After handling an alarm, the O&M personnel can record the handling experience for future reference in a timely manner. Choose Device Management > Alarms Management > Alarm Settings from the main menu. In the navigation pane, choose Experience to manage the experience records.	In the alarm list, select an alarm, click below the list, and click Modify in the Experience area.
   Quick entries for setting alarm rules	O&M personnel can quickly set rules related to an alarm from the quick entries. Only authorized users can perform related operations. For details about the rules, see Table 2.	In the Operation column that contains a desired alarm, click to select a rule to be set.

   Table 2 Introduction to quick entries for rules

   Set Masking Rule	You can set an alarm masking rule to mask alarms that you are not concerned about. The masked alarms will not be displayed on the Current Alarms page.

When monitoring or querying alarms, you can set filter criteria to filter out the alarms. For example, you can set the alarms generated in commissioning scenarios to Maintenance status.
   Set Notification Rule	The system automatically sends the information about alarms that meet the rule conditions to O&M personnel based on the notification method and content template set in the rule. In this way, the O&M personnel can learn about the alarm information and take corresponding measures in a timely manner.
   Setting Intermittent/Toggling Rule	After a rule is set, intermittent or toggling alarms can be discarded or masked to reduce interference caused by repetitive alarms.
