Python netmiko模块的使用

一、简介

此模块用于简化paramiko与网络设备之间的ssh连接,可在windows与Unix平台使用 

二、目前支持的设备

三、实验环境

1.操作系统:win10

2.python版本: python3.6.6

3.netmiko模块版本:2.3.0

四、安装netmiko模块

#前提准备模块（安装netmiko可自动下载依赖项）:Paramiko >= 2.4.1scp >= 0.10.0pyyamlpyserialtextfsm#安装netmikopip install netmiko

ps:没有全部安装前提模块，在使用netmiko没有报错，说明运行代码里没有调用到而已，而不是不需要

五、简单实例

5.1 执行查看命令：show ip int brief

from netmiko import ConnectHandlercisco = {  'device_type':'cisco_ios',  'host':'ip地址',  'username':'用户名',  'password':'密码'}net_connect = ConnectHandler(**cisco)##或者# net_connect = ConnectHandler(device_type='cisco_ios',host='IP地址',username='用户名',password='密码')#找到目前所在视图current_view = net_connect.find_prompt()print(current_view)#执行命令，返回结果为字符串，赋值给outputoutput = net_connect.send_command('show ip int brief')print(output)# #此为在windows里如果/n不能显示回车，则进行如下语句格式化# o_list = output.split("/n")# for line in o_list:#   print(line)

5.2 执行配置命令：手动关闭接口G1/0/29

from netmiko import ConnectHandlercisco = {  'device_type':'cisco_ios',  'host':'ip地址',  'username':'用户名',  'password':'密码'}net_connect = ConnectHandler(**cisco)##或者# net_connect = ConnectHandler(device_type='cisco_ios',host='IP地址',username='用户名',password='密码')#要配置的命令config_commands = ['interface GigabitEthernet1/0/29','shutdown']#提交要配置的命令，input为提交的真实内容input = net_connect.send_config_set(config_commands)#验证shutdown是否执行成功output = net_connect.send_command('show run inter gi1/0/29')print(output)# #此为在windows里如果/n不能显示回车，则进行如下语句格式化# o_list = output.split("/n")# for line in o_list:#   print(line)
