Низкое качество сигнала по RX, у тебя линк на грани отвала (если уже не отвалился).
Судя по логу, там оптика включена.
У тебя два значения
1) Operating value - сигнал в данный момент
2) Threshold value - сигнал при котором выдается авария
Как видишь, сигнал хуже чем показатель при аварийном состоянии.
Нужно стрелять рефляком на наличие проблем, проверять SFP модуль, либо, если потери сервисов нет, поменять значение Threshold value руками и поставить чуть выше значение.
