linux – Intel e1000e以10Mbps的速度运行

这是一款全新的SuperMicro X9SCL-F,带有Intel 82579LM适配器和全新安装的带有cPanel的CentOS 6.2.

我被困在10MBPS,我已经尝试了一切.我也安装了英特尔最新的1.95驱动程序,这似乎解决了其他所有人的问题.

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中产生这样的结果：

[ 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

这个命令让我脱离了网络

ethtool -s eth1 speed ... autoneg off

输出

ethtool eth1

解决方法

由于您似乎已经花了相当多的时间来验证您的设备是否正常工作,因此可能是时候退一步并执行其中一个非常基本的,应该是明显的检查.

仔细检查您连接的交换机/集线器/设备是否实际支持大于10mb的链路速度,并且它没有任何配置,仅将其限制为10mb.
