手把手教网络工程师写python脚本，实现ssh登录交换机修改配置

Netmiko在window系统下安装

pip3 install Netmiko（linux、mac也可以使用该命令）

没报错，就说明Netmiko安装没问题。

python脚本代码

from netmiko import ConnectHandler

alongsw = {

    'device_type': 'huawei',

    'ip':'192.168.1.200',

    'username':'along',

    'password':'along123',

}

connect = ConnectHandler(**alongsw)

print("恭喜阿龙成功登录交换机"+ alongsw['ip'])

config_commands = ['vlan 100 ','name 20210103']

output = connect.send_config_set(config_commands)

print(output)

result = connect.send_command('dis vlan')

print(result)

交换机SSH相关配置

[along]user-interface vty  0 4

[along-ui-vty0-4]authentication-mode aaa

[along-ui-vty0-4]protocol inbound ssh 

[along]aaa

[along-aaa]local-user along password irreversible-cipher 

[along-aaa] local-user along privilege level 15

[along-aaa]local-user along  service-type ssh

[along]ssh user along authentication-type  password

[along]ssh user along service-type stelnet 

[along]stelnet server  enable 

测试一下ssh，能不能登录？
