Понимаю, что тема заезженная, по поиску нашел на форуме все подобное, но ... не фурычит млин...
Итак задача проста:
Схема: Cisco 3750 -> DES 3828 -> access (3016, 3052 и др.) Про Aceess пока забудем... Думаю, настрою позже аналогично...
Сначала пробуем создать транк и в нем два VLAN: управляющий (VLAN100) и магистральный (VLAN101). Сразу объясню в чем проблема: по магистральному VLAN101 трафик ходит, а вот по управляющему VLAN100 3828 не пингуется. Основная функция обоих свичей - маршрутизация. Cisco в ядре, 3828 в мкрайоне.

В такой конфигурации по VLAN101 пинги проходят, апдейты протоколов маршрутизации и тд приходят. Все ок.
А вот управление по VLAN100 недоступно. Почему то:
Код:
C3750#sh int vlan 100
Vlan100 is down, line protocol is down
Подскажите плиз...
PS Пробовал командой
Код:
switchport trunk native vlan 101
делать нативным магистральный VLAN101, но в этом случае вообще пропадает связь
