在ifconfig输出中RX‘错误’和'frame‘的确切含义？
提问于 2010-09-28 09:11:00
我看到了(RHEL)节点(丢包)的网络问题，它似乎也通过ifconfig输出中的“error”和“frame”字段的非零计数来表现出来：
eth2 Link encap:Ethernet HWaddr xx:xx:xx:xx:xx:xx
...
RX packets:277593775 errors:1049 dropped:0 overruns:0 frame:536有没有详细的描述“错误”和“框架”的确切含义？
编辑：ethtool eth2输出：

RX错误意味着NIC正在接收来自发送交换机的格式错误的帧。
帧错误是指在接收到帧时CRC失败。造成这种情况的根本原因可能是电缆不好，或者机器或开关上的接口不好。试着更换电缆，然后移动到交换机上的另一个端口。

在tigon (tg3)驱动程序中，v3.134b版本之前的rxbds_empty事件被记录为帧错误。
您可以通过以下方式检查：
ethtool -S {device}例如：
[root@srv2-mgmt ~]# ethtool -S em1
