Приветствую коллеги!
С 3его января начались проблемы с массовым отключением ONU на одной из веток на Головной Станции(далее ГС).
Несколько ONU с одной ветки начинают отключаться по отсутвствию сигнала и потом снова детектились ГС.

Логически начали искать того кто часто засирает логи, положили глаз на ONU 4,62, постарались всячески заблокировать
Заблокировали что мождно, и порт, и ип, и лицевик, и все равно ГС его старается законектить.
После всех действий ГС вроде успокоилась, ONU перестали отваливаться, но 4,62 так же реконектился.
Но все же проблема возобновилась

В чем может быть проблема, как ее решить?
P.S. На ГС 460 абонентов(ONU), ГС не не ребутали.
