ifconfig 输出中RX“错误”和“帧”的确切含义?

And*_*ner 11 networking linux ifconfig

我看到 (RHEL) 节点出现网络问题(数据包丢失),这似乎也通过 ifconfig 输出中“错误”和“帧”字段的非零计数来体现:

eth2      Link encap:Ethernet  HWaddr xx:xx:xx:xx:xx:xx  
          ...
          RX packets:277593775 errors:1049 dropped:0 overruns:0 frame:536

“错误”和“框架”的确切含义是什么?

编辑:输出ethtool eth2

RX 错误意味着您的 NIC 从传输交换机端口接收格式错误的帧。

帧错误是指收到帧时 CRC 失败。其根本原因可能是电缆不良,或者机器或交换机上的接口不良。尝试更换电缆,然后移至交换机上的另一个端口。
