Dell M620 上的双 NIC 端口仅显示 1 个以太网接口

我有一台 Dell M620 服务器，配备 Intel(R) 以太网 10G 2P X520-k bNDC。但是当我安装 Ubuntu 14.04.02 时，我只能看到系统中的 1 个接口？为什么容量只有 1G/s？应该是 10G/s 吗？

我配置错了吗？我和戴尔的人谈过，他们说硬件没有问题，让我问问 Ubuntu 社区。非常感谢。

我实际上也遇到了同样的问题，因为我已经修复了旧的 ethX 命名方案，并尝试使用 emX / ethX 组合

正如你所做的那样，你可以通过“sudo lshw -C network”获得网卡详细信息。就我而言

  *-network:0 DISABLED

   logical name: p2p1

   serial: xxxxxxx
   width: 64 bits
   clock: 33MHz
   capabilities: pm msi msix pciexpress vpd bus_master 
   cap_list rom ethernet physical fibre
   configuration: autonegotiation=off broadcast=yes driver=ixgbe 
   driverversion=3.19.1-k firmware=0x8000081f latency=0 link=no 
   multicast=yes

   memory:d5100000-d51fffff memory:d5200000-d52fffff

现在使用 lspci 输出中的“逻辑名称”（对于扩展卡，使用 pXpX 方案），在 /etc/network/interfaces 中将激活网络接口

我在富士通系统上运行良好，其中设备显示为 ethX，并且可以使用 ethtool 探测未定义的网络接口（sudo ethtool eth2）

所以另一种方法是将命名改回 ethX（emX / pXpX 是新的命名方案）

  Edit /etc/default/grub and find these lines:
  GRUB_CMDLINE_LINUX_DEFAULT=""
  GRUB_CMDLINE_LINUX=""

  Add biosdevname=0, just like this:
  GRUB_CMDLINE_LINUX_DEFAULT="biosdevname=0"
  GRUB_CMDLINE_LINUX="biosdevname=0"

  Then run:
  sudo update-grub
  sudo reboot
