У меня такая проблема. Есть свитч DES- 3326SR, с прошивкой
4.03-B13(до этого были 4.03-B01, 4.01-B39).Замена прошивок результата не дали. Время от времени вот что происходит: люди работающие на этом свитче пингуются, у них есть локалка как таковая.
но при этом идет зарезка на интернет. Точнее сказать работает всего два сайта www.rambler.ru, www.icq.com. DES-3226 перестает пинговаться, не работает telnet и web, но люди за свитчом видны в сети. Начинает все работать только после того, как выключишь и снова включишь порт на тот VLAN который дал сбой.


DNS----DES-3326SR----vlan28 vlan11(DES-3226S) vlan27 vlan24 vlan26 vlan29

Заранее Спасибо!!! конфиг 3326SR сморти ниже
