Python批量备份交换机配置+自动巡检
继上次发帖批量备份的功能后,有坛友要求增加功能,目前版本支持SSH、Telnet、自定义端口,增加了部分异常处理。设备厂商支持思科、华为、华三。
自动巡检功能考虑到不同设备回显有所不同,需要大量正则匹配,暂时没时间搞这些,所以索性将命令回显全部显示,没做进一步的回显提取。
以下是程序运行示例:
#自动备份配置:
备份完成后,将配置保存于程序目录下的conf_bak文件夹下,如图所示:
#自动巡检交换机设备:
使用前需创建excel文档,写入设备登录信息,格式如下:
本人编码能力一般,没学过多少,大佬们勿喷,源码奉上:

不错不错给你点个赞 谢谢分享 谢谢分享 菜鸡学习学习,想要把交换机巡检的输出打印在cmd显示怎么弄的? 需要这样的东西 baigei2333 发表于 2023-3-27 08:43
菜鸡学习学习,想要把交换机巡检的输出打印在cmd显示怎么弄的?
在cmd里运行就好了呀,python ./xxx.py winty 发表于 2023-3-27 09:12
在cmd里运行就好了呀,python ./xxx.py
这样吗,谢谢 谢谢,之前那个也不错,不过就不能用于其他交换机厂家 谢谢分享,学习中
