Доброго времени суток. Столкнулся с такой ситуацией. На линии стоит Dlink DGS-3420-26SC оптическим портом соединён с SNR 2965_24T в 25 порт. С SRN 2965_24T в 23 порт воткнута магистраль на следующее оборудование snr 2965_8T в 7 порт. Со стороны snr 2965_8T идёт петля и не один из двух snr её не замечает. Тем самым вырубается оптический порт на Dlink DGS-3420-26SC. Можете ткнуть пальцем где я и что не правильно настроил?

Тыкните пальцем что не так я делаю?

Доброго времени суток. Случилась беда с 2990. Подключили (гении) на 24 вольта акб. Нашли пару сгоревших деталей. Хотелось бы уточнить маркировку дабы заменить их.

Здравствуйте ещё раз.. Dlink используем в DHCP Сервере вот такой формат поля Option 82: http://www.dlink.ru/ru/faq/62/print_228.html А мы принимаем с SNR-2990 : Это с вашего сайта Если пакет с Option 82, то пишем в syslog информацию: log ( info, concat( о коммутаторе и порту подключения, с которого пришел пакет: «Switch MAC:», binary-to-ascii(16, 8, «:», option agent.remote-id), «Switch port:», binary-to-ascii(10, 8, «.», option agent.circuit-id) )); } Если можно вышлите пожалуйста точнее какой формат поля Option 82 Вы используете.

Можете тыкнуть пальцем где я не правильно делаю? При такой настройке клиент не может получить айпи.. ! service dhcp ! ip forward-protocol udp bootps ip dhcp relay information option ip dhcp relay information option subscriber-id format hex ! ! ! ! ! ! !

Спасибо, помогло.

Спасибо, помогло. Пока не нашёл настройку syslog сервера. Для отправки логов на сервер. Из мануала на сайте: Направление вывода на syslog-сервер: info-center loghost "server_ip" facility facility channel "channel_id" server_ip - адрес syslog-сервера facility - категория сообщения для syslog-серверa channel_id - номер канала.

Доброго времени суток. Взяли на замену DGS-3627 (Dlink) - SNR-S2990G UPS на вооружение. Накопилось очень много вопросов. 1) Есть на старом кучерявом Dlink команда "trusted_host network", есть ли аналог тут? 2) При прописывании команды sh info-center logsdram говорит что её попросту нету. Тем самым не могу настроить оповещение. Либо я что то не так делаю, помогите если есть возможность. Версия ПО: SoftWare Version 7.0.3.5(R0102.0266) BootRom Version 7.1.41 HardWare Version 1.0.2-UPS
