使用了telnetlib模块,首先登录到交换机,列出并获取配置文件的名称,然后通过tftp协议将配置文件传输到文件服务器上,为避免配置文件覆盖,将备份的配置文件名称统一加入日期以作区分。
1. 登录方式和口令有好几种,比较懒惰,通过不同列表以做区分,如果每个交换机口令都不相同的话,就需要额外处理了。
2. 交换机的配置文件也有多种类型,也是通过列表进行区分。
3. 有些交换机支持ftp和sftp,但测试发现有些虽然有相应的客户端命令,但传输总有问题。也不能将每个交换机都配置为ftp服务器,不安全也不方便。最后采用tftp解决。tftp比较简单,没有办法创建目录以区分不同日期的备份。好在配置文件已经加入了日期做区分,马马虎虎可以运行了。
