1、背景介绍
目前鲲鹏920s上面可以使用华为提供的serdestool进行眼图查看，查看100G网卡的眼图等
2、操作步骤
首先需要安装欧拉系统
安装后可以使用everything源进行图形化配置
将华为提供的serdestool工具拷贝到模块上面
主要有三个文件 serdestool serdescbb2203.ko ++libsecurec.so++ 下载地址见 https://download.csdn.net/download/jj12345jj198999/90309558
步骤1 将serdestool工具放置到/usr/bin目录下。
步骤2 进入该目录执行chmod 777 serdestool赋予权限。
步骤3 将serdescbb2203.ko文件放到对应填好的目录下，默认是在root目录下，可自行执行insmod serdescbb2203.ko chipn=1 装载环境。
步骤4 将libsecurec.so文件放open Euler系统l/ib64文件夹下
在环境上敲Serdestool命令时会显正常如下，即代表环境已经安装完成
serdestool命令格式如下，具体可以参考下载链接里面的使用说明
为了查看100G网卡的眼图，先确认网卡所在的serdes，可以通过下面命令查看，usemode中的eth就代表是100G网卡
