Здравствуйте. Не получается настроить опцию 82 на коммутаторе, сетевая карта не получает адреса.

Вот конфиг свича нашего, подскажите что не так:

Добрый день. Коммутатор подключен сразу к DHCP-серверу? Покажите его конфиг.

Если используете ISC-DHCP, то попробуйте добавить в конфигурацию коммутатора ip dhcp snooping information option subscriber-id format hex

По L2 через 5-7 коммутаторов, dhcp сервер поднят на микротике. Со свитчами d-link и eltex данная схема работает.

В таком случае хотелось бы увидеть конфиги d-link и eltex, а также настройки DHCP сервера на Mikrotik.

@snaky_85 А если на Eltex прописать ip dhcp information option format-type option sv, то будет ли работать релей? Есть подозрение, что причина в неверном формате опции.
