华为交换机常用的Python脚本可以用于自动化网络管理和监控，可以帮助网络管理员提高工作效率和降低操作风险。

以下是一些常用的Python脚本示例：

1、登录华为交换机

from netmiko import ConnectHandlerhuawei_switch = {'device_type': 'huawei','ip': '192.168.1.1','username': 'admin','password': 'password',
}net_connect = ConnectHandler(**huawei_switch)
output = net_connect.send_command('display current-configuration')
print(output)
net_connect.disconnect()

2、配置华为交换机

from netmiko import ConnectHandlerhuawei_switch = {'device_type': 'huawei','ip': '192.168.1.1','username': 'admin','password': 'password',
}net_connect = ConnectHandler(**huawei_switch)
config_commands = ['interface gigabitethernet 0/0/1', 'ip address 192.168.2.1 255.255.255.0']
output = net_connect.send_config_set(config_commands)
print(output)
net_connect.disconnect()

3、查看华为交换机端口信息

from netmiko import ConnectHandlerhuawei_switch = {'device_type': 'huawei','ip': '192.168.1.1','username': 'admin','password': 'password',
}net_connect = ConnectHandler(**huawei_switch)
output = net_connect.send_command('display interface GigabitEthernet0/0/1')
print(output)
net_connect.disconnect()

4、查看华为交换机接口状态

from netmiko import ConnectHandlerhuawei_switch = {'device_type': 'huawei','ip': '192.168.1.1','username': 'admin','password': 'password',
}net_connect = ConnectHandler(**huawei_switch)
output = net_connect.send_command('display interface GigabitEthernet0/0/1')
if 'Line protocol state' in output and 'UP' in output:print('Interface is UP')
else:print('Interface is DOWN')
net_connect.disconnect()

5、查看华为交换机 ARP 表

from netmiko import ConnectHandlerhuawei_switch = {'device_type': 'huawei','ip': '192.168.1.1','username': 'admin','password': 'password',
}net_connect = ConnectHandler(**huawei_switch)
output = net_connect.send_command('display arp')
print(output)
net_connect.disconnect()

6、查看华为交换机 CPU 使用率

from netmiko import ConnectHandlerhuawei_switch = {'device_type': 'huawei','ip': '192.168.1.1','username': 'admin','password': 'password',
}net_connect = ConnectHandler(**huawei_switch)
output = net_connect.send_command('display cpu-usage')
print(output)
net_connect.disconnect()

7、查看华为交换机内存使用情况

from netmiko import ConnectHandlerhuawei_switch = {'device_type': 'huawei','ip': '192.168.1.1','username': 'admin','password': 'password',
}net_connect = ConnectHandler(**huawei_switch)
output = net_connect.send_command('display memory-usage')
print(output)
net_connect.disconnect()

8、查看华为交换机端口带宽利用率

from netmiko import ConnectHandlerhuawei_switch = {'device_type': 'huawei','ip': '192.168.1.1','username': 'admin','password': 'password',
}net_connect = ConnectHandler(**huawei_switch)
output = net_connect.send_command('display interface GigabitEthernet0/0/1 | include "Input rate|"Output rate"')
print(output)
net_connect.disconnect()

9、查看华为交换机 VLAN 信息

from netmiko import ConnectHandlerhuawei_switch = {'device_type': 'huawei','ip': '192.168.1.1','username': 'admin','password': 'password',
}net_connect = ConnectHandler(**huawei_switch)
output = net_connect.send_command('display vlan')
print(output)
net_connect.disconnect()

10、查看华为交换机 MAC 地址表

from netmiko import ConnectHandlerhuawei_switch = {'device_type': 'huawei','ip': '192.168.1.1','username': 'admin','password': 'password',
}net_connect = ConnectHandler(**huawei_switch)
output = net_connect.send_command('display mac-address')
print(output)
net_connect.disconnect()

以上是一些常用的华为交换机的 Python 脚本示例，可以帮助网络管理员进行自动化网络管理和监控，提高工作效率和减少操作风险。需要注意的是，华为交换机的命令行界面和输出格式可能会因型号和软件版本的不同而有所不同，需要根据实际情况进行调整和修改。
