我在运行 Ubuntu Server 12.04 的服务器上安装了三块 Intel X540-T1，但都无法正常工作，没有链路指示灯，没有发送或接收数据包，并且无论设置为 dhcp 还是静态，ip4 或 ip6 上都没有连接。此外，dmesg 无法检测到电缆连接或断开连接。
我将默认的 ixgbe 驱动程序更新为英特尔的最新版本 (3.11.33)，没有任何变化。以太网控制器被报告为 X540-AT2（这可能是一个我不知道如何修复的问题），但子系统是 X540-T1，所以我相信这可能是故意的。
有谁有这方面的经验可以提供帮助吗？

答案1
事实证明，原型 NIC 无法直接与任何非原型 NIC 通信。我不确定具体原因。Ubuntu 中的 x540-T1 可以很好地相互通信，至少在安装最新的 Intel 驱动程序之后（可能在此之前）。感谢大家的帮助。
