对Python网络设备巡检脚本的实例讲解-创新互联
1、基本信息

我公司之前采用的是人工巡检,但奈何有大量网络设备,往往巡检需要花掉一上午(还是手速快的话),浪费时间浪费生命。
这段时间正好在学 Python ,于是乎想(其)要(实)解(就)放(是)双(懒)手。
好了,脚本很长又比较挫,有耐心就看看吧。
需要巡检的设备如下:
|
设备清单 |
设备型号 |
|
防火墙 |
华为 E8000E |
|
H3C M9006 |
|
|
飞塔 FG3950B |
|
|
交换机 |
华为 S9306 |
|
H3C S12508 |
|
|
Cisco N7K |
|
|
路由器 |
华为 NE40E |
|
负载 |
Radware RD5412 |
|
Radware RD6420 |
2、采集数据并写入文件
# 相关设备巡检命令就不介绍了。。。
