脚本使用前提条件

1.目标设备必须是linux机器

2.目标机器可以被ssh 次是通过python ssh模块来获取信息的，因此设备必须要可以ssh到其上面的；

3.本次py脚本是在windows机器下的（请注意，可上外网），即winodws上有python环境（python3版本）

脚本使用时需要修改的地方

1.运行次py脚本前，必须先要在所有linux机器上运行lldp.sh脚本：

即在安装系统前，要保证安装lldpad软件包：

2.修改py脚本中ssh端口，用户名及用户密码即可。

3.注意ip列表/输出文件存放路径

4.保证如下python模块已被安装，如未安装，则在执行过程会报错，根据提示，使用pip安装即可：

脚本输出结果说明

1.输出结果如下文件：SFG.xlsx

# 次脚本输出的信息如下：

系统主机名；

带外ip、掩码、网关；

sn；

服务器网卡名、网卡mac、网卡速率、收发光衰；

上联交换机主机名、交换机端口、所属vlan、交换机下服务器描述信息、

2.注意：如果有光衰异常的情况，次脚本会对次目标进行标注：
