This view shows only active alarm.
It could take 1-2 minutes till the alarm is shown and the alarm is removed as soon as the port is up again.
The best way to test it is not to restart the PC but to disconnect the ENet cable - then you should get the alarm in about 1-2 minutes.
Then connect the PC again and after a short time the alarm is gone because the "up alarm" acknowledges/removes the active link down alarm.
