我在HP ML310e Gen 8 v2服务器（还有板载双端口Broadcom BCM5720）中有一个英特尔四端口千兆以太网控制器。
当我从Ubuntu桌面实时USB（16.04）引导时，所有六个端口均按预期工作：连接电缆后，它们立即获得链接，端口上的LED立即点亮，而我的交换机上的相应LED点亮。
我安装了Ubuntu Server（16.04），并且所有英特尔端口都没有链接。LED永不点亮，并且ethtool报告每个端口的“检测到链接：否”。使用久经考验的电缆。Broadcom端口工作正常。我可以使用ethtool -p使Intel卡上每个端口的LED闪烁。
我在这里发现了一个表面上类似问题的报告：https : //bbs.archlinux.org/viewtopic.php? id =159454但是，该问题的解决方法是：
echo on > /sys/bus/pci/devices/0000\:09\:00.0/power/control
（针对每个正确的PCI ID）-在我的情况下，该密钥已经设置为“ on”。
由于在启动Live USB桌面时该卡可以完美工作，因此我认为该卡和电缆都可以，但无法从已安装的Ubuntu Server上使它正常工作。这是我现在尝试的第三个从头开始安装。在以前的尝试中，我还尝试从Intel的站点下载并构建e1000e驱动程序，但这没有任何区别。
非常感谢社区提供的任何建议-谢谢。

显示为DISABLED的接口恰好是未在/ etc / network / interfaces中声明的接口。请将文件修改为：

顺便说一句，如果声明的接口eno1有望到达Internet，则需要DNS名称服务器。我可以自由地在我上面的建议编辑中提出建议。
重新启动并检查：
sudo lshw -C network
英特尔端口不再被禁用吗？如果是这样，可以将电缆转移到其中之一，重新排列/ etc / network / interfaces并继续。
