Setting Alarm Reversion for a Specified Port

During a new deployment, certain alarms that are reasonable but meaningless occur. For example, when you configure a tributary board, line board, or Ethernet board for a service but not connect cables, the corresponding LOS alarm is generated. After the alarm reversion is set, the alarm is not displayed. This does not affect the network monitoring that is performed by maintainers.

Context

If you set the alarm reversion for a port, the displayed status of all alarms that support the alarm reversion on this port is contrary to their actual status. Currently, you can set the alarm reversion for the following alarms:

Procedure

In the NE Explorer, select the NE and choose Alarm > NE Alarm Attribute from the Function Tree.
Set Alarm Reversion to Enable (Auto Restore) or Enable (Manually Restore). Click Apply.
NOTE:
After the port alarm is cleared, if you set the Alarm Reversion to Enable (Auto Restore), the reversion setting is automatically cancelled at the NE side. Thus, the alarm status returns to normal. If the Alarm Reversion is set to Enable (Manually Restore), the alarm status can return to normal only after the alarm reversion setting is manually cancelled. If the Alarm Reversion is set to Disable, you cannot set alarm reversion at the port.
In the NE Explorer, select a board and choose Alarm > Alarm Reversion from the Function Tree.
In the Alarm Reversion, set the Reversion Status to Enabled.
Click Apply.

Result

When you set the alarm reversion for a port, the alarm status on this port is opposite to the actual situation. That is, alarms are not reported even if they exist.
When you set the alarm reversion for a port, the alarm status of the board does not change, and the alarm indicator still indicates the actual running status of the equipment.
