  • стек cisco 3850

    Доброго времени суток, коллеги! Выручайте, что то происходит с сеткой не могу понять в чем дело. Часть серверов доступна а часть нет, даже пинг не проходит. Есть несколько сетей пользовательских
    172.17.11x.0/24, x от 1 до 6. Люди физически воткнуты в коммутаторы cisco catalyst 2960G, аплинки от каждого свитча идут в своеобразное ядро состоящее из стека cisco catalyst 3850. Как раз на этот стек пока падают все подозрения. Подскажите как проверить что cisco стек живой?

                какая то ошибка в ядре ios. Или ошибка памяти. Если вы видите это 1 раз то можно забить болт. Если это повторяется регулярно то похоже на аппаратную проблему и отказ оборудования
