На коммутаторе DES-3526 проблема такого плана:
Перестал пускать по логину и паролю, причем по этому же логину и паролю но через вэб интерфейс и сериал порт заходит. Скачал конфиг с нормально работающего коммутатора, поправил, залил на неработающий, не помогло. Проблема осталась. Решил сначала сделать резет конфиг, а потом залить еще раз. Сделал резет, после перезапуска он спросил пароль. Подскажите этот дефолтовский пароль (если он есть конечно (по моему старому не пускает)). И собственно почему по телнету не принимает пароль. Заранее спасибо.

конфиг с этого свича:
