对Python网络设备巡检脚本的实例讲解-创新互联
1、基本信息
泉港ssl适用于网站、小程序/APP、API接口等需要进行数据传输应用场景,ssl证书未来市场广阔!成为创新互联的ssl证书销售渠道,可以享受市场价格4-6折优惠!如果有意向欢迎电话联系或者加微信:18982081108(备注:SSL证书合作)期待与您的合作!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。。。
