基于python netmiko模块实现对华三设备的管理

基于python netmiko模块实现对华三设备的管理

1、拓扑图及试验环境

华三路由器使用官方模拟器（HCL）实现，其中使用host（本地主机）与主机物理网卡进行桥接。Python安装在真实主机的一个Vmware虚拟机中，虚拟机也采用桥接模式与物理网卡桥接。

2、python脚本

导入netmiko模块前需要安装此模块：pip install netmiko

#导入netmiko模块
importnetmiko
#以字典形式定义登录信息
R1={'device_type':'hp_comware','ip':'10.0.0.10','username':'test','password':'abc'}
R2={'device_type':'hp_comware','ip':'10.0.0.11','username':'test','password':'abc'}
R3={'device_type':'hp_comware','ip':'10.0.0.12','username':'test','password':'abc'}
#使用netmiko的ConnectHandler函数连接路由器
connection1=netmiko.ConnectHandler(**R1)
connection2=netmiko.ConnectHandler(**R2)
connection3=netmiko.ConnectHandler(**R3)
#使用netmiko的send_command函数在路由器上执行命令：
output1=connection1.send_command('displayipinterfacebrief',strip_command=False,strip_prompt=False)
output2=connection2.send_command('displayipinterfacebrief',strip_command=False,strip_prompt=False)
output3=connection3.send_command('displayipinterfacebrief',strip_command=False,strip_prompt=False)

print(connection1.send_command('displayipinterfacebrief',strip_command=False,strip_prompt=False))
print(connection1.send_command('displayversion',strip_command=False,strip_prompt=False))
print(connection1.send_command('displayinterfacebrief',strip_command=False,strip_prompt=False))
print(connection1.send_command('displayarp',strip_command=False,strip_prompt=False))
print(connection1.send_command('displaymac-address',strip_command=False,strip_prompt=False))
print(connection1.send_command('displaylogbuffer',strip_command=False,strip_prompt=False))

输出效果如下：
