Системник с интегрированной сетевой картой (enp2s0), в pci-слоты вставлены ещё две одинаковые сетевые Realtek-овские карты (enp4s0 и enp4s1) для основного интернет-канала и резервного соответственно.
Centos7.
Работает только первая карта enp4s0: интерфейс поднимается, пакеты ходят нормально. Вторая enp4s1 не работает. Просто не поднимается. Никакие манипуляции не помогают.
Интернет «на патчкорде» в enp4s1 есть 100%, проверял. «Лампочки» светятся только на карте enp4s0. На второй карте enp4s1 - изредка одна помигивает зелёным. (Когда включаешь системник, то до того момента пока Centos не загрузится обе карты перемигиваются лампочками, как только загрузилось - enp4s1 «тухнет»).
Как второй интерфейс поднять???
