Всем привет!
Пытаюсь поднять SFP порты на плате расширения Intel X710.
В SFP порт воткнут " SFP патчкорд" с другой стороны которого свитч TP Link и его SFP порт. Кабель рабочий, между двумя свитчами SFP линк прекрасно поднимается.
А воть между Свитчем и компьютером c платой X710 под управлением Linux, лаже линк не загорается.
Т.е. как устройство оно есть. Модуль загружен. «Кабель» определён. Но вот состояние NO-CARRIER.
Надо как-то принудительно поднять линк? А как?
Вот так Linux всё это видит:
