python - Netmiko 多供应商备份 running-config Python 脚本

问题描述

关于 python 和 Netmiko 需要帮助使用多个设备进行运行配置备份，例如 ex：Cisco Aruba 和带有单个 python 脚本的 brocade 交换机，为每个供应商读取不同的 .csv 文件。或 CSV 文件应以以下格式显示。

我尝试导入 CSV 格式，下面的代码是否出错。

**device_type        ip                username            password           port**
cisco_ios           192.168.1.2        cisco            C1s??0123$5            22
brocade_fastiron    192.168.1.3        user             B1sc0123$5             22

解决方案

只需创建函数来获取文件信息和设备配置。

使用 pandas 模块或 CSV 模块读取您的 CSV/excel 文件并遍历行以获取详细信息。

from netmiko import ConnectHandler
import pandas as pd

#获取设备配置的函数

def get_device_conf(IP,user,password,device_type):

    devlist = {'device_type': device_type,
       'ip': IP,
       'username': user,
       'password': password,
     }

    net_connect = ConnectHandler(**devlist)
    output = net_connect.send_command("show running-config")
    #"do what you want to do with this output, you can save to file also"
    net_connect.close()

#从 csv 文件中获取设备详细信息

def get_device_detail(filename):

    df = pd.read_csv(filename)
    for index, row in df.iterrows(): 
        device_type=row["device_type"]
        IP=row["IP"]
        username=row["username"]            
        password=row["password"]
    
        get_device_conf(IP,user,password,device_type) #call the get config function to collect config and perform any action

#调用 get_device_details 函数来运行这两个函数并执行操作

get_device_detail(filename)

#如果您有多个文件，那么只需创建一个文件名列表并申请一个循环来遍历所有文件。

例子：

list_filenames=["file1.csv","file2.csv","file3.csv"]

for filename in list_filenames:
    get_device_detail(filename)
