python 自动化运脚本
按照oxidized搭建的CMDB 为数据源。自动向数据库读取账号密码，设备名称，等 并输出状态信息 如图所示
数据库字段如下 enable 字段存放思科的enable密码，login 是登陆方式 存放http登陆，ssh 和telnet等登陆方式。device 是设备类型。
第一段代码 批量抓取思科，华三的配置，命令部分我已经做了注释（具体模块使用可以百度）
可以根据此脚本更改命令列表，比如批量更改网络设备密码，批量备份配置到ftp，批量开启snmp，批量指定syslog服务器，批量设置ntp ,批量............

此python文件执行完成后 生成的log会保存到本地。
用正则表达式 读取 参数进行输出 只输出了华三设备
