NIC 端口在 ifstat 中看到 CRC 错误

适用于

• FAS / AFF 系统
• 网络适配器

问题描述

• ifstat 命令的输出在受影响的端口上显示高 CRC 错误：

::> system node run -node <NODE_NAME> -command ifstat <PORT>

-- interface  e4a  (7 hours, 33 minutes, 13 seconds) --

• 事件日志中报告了以下错误：

[Node-02: vifmgr: vifmgr.cluscheck.crcerrors:alert]: Port e4a on node Node-02 is reporting a high number of observed CRC errors.

• IFCONFIG-VVVM 可能显示 SFP Rx 功率低于预期：
