用python脚本自动备份网络设备配置

脚本内容在此备份一下。

#! /usr/bin/env python3

from netmiko import ConnectHandler             #导入库
import os
import time
def cisco_ios (ip,username,password,secret):    #定义cisco_ios函数
    cisco = {
        "device_type":"cisco_ios",   #设备类型为“cisco_ios”
        "ip":ip,                                  #传入ip参数
        "username":username,       #传入登陆用户名
        "password":password,        #传入登陆密码
        "secret":secret                     #传入sceret密码
    }
    command = ["show run"]         #执行show run 命令。此列表可以加入多条命令
    connect = ConnectHandler(**cisco)      #对不同品牌设备的预定义的内容。这个地方建议看一下源码，我这一句话解释不太清楚。
    full_config = ""
    for cmd in command:
        config = connect.send_command(cmd)
        full_config += config
    return full_config
    connect.disconnect()

now = time.strftime("%Y-%m-%d", time.localtime())        #定义时间格式，备份文件名用到

if __name__ == "__main__":
    host = ["10.163.4.39","10.163.0.126","10.163.1.253","10.163.1.254","10.163.1.133","10.163.1.134","10.163.1.135","10.163.1.129","10.163.1.130","10.163.1.131","10.16
3.1.132"]                 #需要备份的ip地址放入列表中
    for ip in host:          #循环列表，保存配置
        conf = cisco_ios(ip, "admin", "admin123", "admin123")
        with open(f"/root/backup/beijing/{ip}/cfg_bak_{ip}_{now}.txt", mode="a") as f1:    
            f1.write(conf)         #保存到文件中
        time.sleep(30)         #每个IP之间等待30秒，给系统点反应时间
