Проблема со связями NIC

Question

Я все еще новичок в мире Linux, но причина, по которой я создал свой компьютер, - это изучить его, поэтому, пожалуйста, помните об этом, поскольку я могу делать что-то очевидное неправильно.

Краткая схема моей установки, чтобы вы могли понять, чего я пытаюсь достичь: у меня есть пользовательский ПК, на котором я установил Ubuntu Server для размещения различных виртуальных машин. Жесткие диски виртуальных машин расположены на моем NAS, который я подключаю через ISCSI, и я хочу связать два порта вместе, чтобы улучшить скорость. На данный момент у меня есть 4-портовая плата PCI-E, два порта, которые я хочу связать для ISCSI непосредственно в моем NAS, один должен оставаться отключенным, и один будет для моей общей возможности подключения. В качестве побочного примечания, NIC материнской платы (enp30s0) бесполезен, он сработает через несколько секунд, когда VNC активен, поэтому я установил случайные IP-данные, чтобы он не вмешивался, поскольку я не знаю, как его окончательно отключить (это отображается как неуправляемое на панели управления).

Я пробовал следовать этому руководству: https://www.unixmen.com/linux-basics-create-network-bonding-on-ubuntu-14-10/ а также https://help.ubuntu.com/community/UbuntuBonding, но встретили следующие ошибки:

Из того, что я могу скажите, что неправильно обнаруживает сетевые карты, которые я пытался связать, несмотря на то, что (насколько мне известно) меня правильно настраивали в соответствии с руководствами, на которые я смотрел. Я был бы признателен за любую помощь в этом.
