Свитч DES-3526. Версия прошивки 5.01-B09
В один из моментов свитч перестал пинговаться и пускать по http, ssh. Перезагрузка свитча не помогла.
Думал, что проблема в safeguard. Зашел через COM-порт: ни изменение лимитов safeguard engine, ни отключение его как такового проблему не решает.
В чем может быть проблема?
P.S. сервера на свитче прекрасно работают. Трудности лишь с самим des'ом.

У Вас управление выделено в отдельный VLAN? И что значит в режиме хаба? Неуправляемого свитча для Вас наверное.

Именно для меня. Кроме как по COM-порту подключиться к нему не могу. Никаких функций кроме как примитивной коммутации он тоже не выполняет.

Ну тогда первым делом вытащите управление в отдельный VLAN.

Как раз то что у вас управление от любого флуда в клиентском VLAN-е не будет отваливаться. Я Вам на всякий случай последнюю версию прошивки выслал. Попробуйте перепрошить устройство.
