Здравствуйте.Запланировал сделать сегментацию сети. В настоящее время сеть плоская 192.168.32.0/23.
Сеть объединяет несколько зданий, часть из них соединена по оптике(1000BASE-LX), часть по меди(ADSL).
Для сегментации были куплен dlink dgs 3610-26g. На нём сделан следующий конфиг для тестирования:

В настоящее время для теста подключил его к сети 192.168.32.0/23 через порт GigabitEthernet 0/13.Порт всегда в статусе UP.
Проблема следующая, периодически перестаёт быть достыпным 192.168.33.254. Интервал недоступности от 2-3 сек до 15-20.
