Всем добрый день.
Вообщем тема такая:
Есть циска 5400, которая одним фастом смотрит на вышестоящего оператора, другим концом смотрит в каталист 2950.
Далее этот каталист (назовем его №1) смотрит в конвертор - e1 - e1- конвертор - каталист №2 (так назваемый "разводящий"). Фасты каталиста № 2 смотрят в другие конверторы, и соответсвенно в другие каталисты (уже конечные). Получаеться что каталист №2 берет трафик с каталиста №1 и раскидывает его по каталистам №3 и №4.
К каталистам №3 и №4 подключены DSLAM, к DSLAM подключены конечные клиенты. Клиенты в разных VLAN. Сами каталисты, циска и DSLAM между собой в одном VLAN. А вот теперь проблема:
Время от времени, обычно вечером и утром пропадает связь с каталистом №3 (и с DSLAM к нему подключенным). Причем пропадает она очень интересно. То есть, с 5400 циски каталист №3 я не пингую, но великолепно вижу его (№3) с любого другого каталиста и любого другого устройства, находящимся в этом же VLAN. С 5400 циски вижу все, за исключением каталиста №3
Делема, над которой бьемся уже месяц.
