英特尔e1000e停留在10Mbps

这是一个全新的SuperMicro X9SCL-F，带有一个Intel 82579LM适配器和全新安装的CentOS 6.2以及cPanel。

我被困在10MBPS，我已经尝试了一切。我已经安装了最新的英特尔1.95驱动程序，似乎已经解决了这个问题给其他人。

这些命令什么都不做。

ethtool -s eth1 speed 100 duplex half ethtool -s eth1 speed 1000 duplex half ethtool -s eth1 speed 100 duplex full ethtool -s eth1 speed 1000 duplex full

他们在dmesg中得到这个结果：

 [ 1081.662365] e1000e 0000:02:00.0: eth1: Reset adapter [ 1084.298376] e1000e: eth1 NIC Link is Up 10 Mbps Half Duplex, Flow Control: None [ 1084.298443] e1000e 0000:02:00.0: eth1: Autonegotiated half duplex but link partner cannot autoneg. Try forcing full duplex if link gets many collisions. [ 1084.298446] e1000e 0000:02:00.0: eth1: 10/100 speed: disabling TSO

这个命令把我从networking中敲了出来

 ethtool -s eth1 speed ... autoneg off

输出

ethtool eth1

既然看起来你已经花了相当多的时间来validation你的设备正在工作，那么可能是时候退一步来执行一个真正基本的，应该是明显的检查。

仔细检查你所连接的交换机/集线器/设备，实际上支持的链路速度大于10mb，并且没有任何configuration，只能将其限制为10mb。

我看到你提到了自动协商，但是如果closures自动协商，则需要在双方（服务器端和交换机端）进行。一般来说，如果卡在自动协商时遇到问题，可能是由于外部干扰源。正如Squidly所说，你可能有一个糟糕的电缆。所以，我对你的build议是这样的：

尝试在双方closures设置自动协商，手动将链接的双方达到1000 /完整。
否则，请尝试用新的或已知的电缆更换电缆。
这是完全可能的，你只是有一个坏的网卡，这是已知的事情发生。

这在过去发生在我身上。它是否尝试过交换机上的不同端口和不同的以太网电缆。我已经看到了一个坏的电缆会给你的链接，但不显示你有一个足够好的连接到引脚，以保持适当的质量信号高于10 /半。

我只是有同样的问题。我的问题是我通过ipmitool / SOL通过相同的接口连接。

一旦我断开SOL，我的速度跳到1000mbps
