python3以ftp方式备份华为交换机

发布时间：2019-09-26 07:28:38编辑：auto阅读（1812）

客户这里，有很多华为S系列交换机，基本时都是2700，5700系列。数量很多，原来都是手工登陆备份，费时，费力。后来想用python脚本备份交换机配置文件。
思路：
1、华为交换机的配置文件都是以vrpcfg.zip文件方式保存在交换机内存中
2、华为的交换机都支持ftp服务器
3、使用python3脚本批量备份保存在windows主机指定目录
4、有些设备可能故障等原因，无法进行备份，需要记录失败日志

前提条件，windows上已经安装好python3.6，配置好环境变量，脚本如下：

#! env python
#coding=utf-8

#ver2.0 
#使用ftp方式备份华为交换机配置文件
#python3版本
from ftplib import FTP

运行时，将信息输出在终端

运行完成后，可以将错误信息以文本的方式保存


然后查看保存的交换机配置文件


在windows上开启计划任务，定期执行

需要使用此脚本时，注意更换字典中的主机ip地址，用户密码，文件路径等
