各位兄弟，以前写过一个用python连接h3c交换机，并执行h3c交换机命令的程序，今天来分享一个连接多个h3c交换机，并用多线程同步执行的例子，这也是我们做IT运维需要学习的，咱也不多说了，接下来就可以实际操作下，首先我们来配置交换机：首先我们创建一个可以通过SSH连接的账户，如下图：多个h3c交换机是类似的配置，这样我们交换机就配置完毕了。import netmiko
from netmiko import ConnectHandler
from concurrent.futures import ThreadPoolExecutor
# -------------------------- 在这里修改你的交换机列表 --------------------------
switch_list = [
{
'device_type': 'hp_comware',
'host': '10.0.0.21',
'port': 22,
'username': 'admin',
'password': 'shunfaxinxi@123',
},
{
'device_type': 'hp_comware',
'host': '10.0.0.9',
'port': 22,
'username': 'admin',
'password': 'shunfaxinxi@123',
},
{
'device_type': 'hp_comware',
'host': '10.0.0.20',
'port': 22,
'username': 'admin',
'password': 'shunfaxinxi@123',
},
{
'device_type': 'hp_comware',
'host': '10.0.0.27',
'port': 22,
'username': 'admin',
'password': 'shunfaxinxi@123',
},
]
# 要批量执行的命令
commands = ['dis cpu', 'dis memory']
# -------------------------- 批量执行函数 --------------------------
def run_command_on_switch(switch):
ip = switch['host']
print(f"\n==== 正在连接交换机：{ip} ====")
try:
# 连接
net_connect = ConnectHandler(**switch)
result = f"\n{'=' * 50}\n交换机 {ip} 执行结果\n{'=' * 50}\n"
# 逐条执行命令
for cmd in commands:
output = net_connect.send_command(cmd)
result += f"\n【命令】: {cmd}\n{output}\n"
net_connect.disconnect()
return result
except Exception as e:
return f"\n==== 交换机 {ip} 连接失败：{str(e)} ===="
# -------------------------- 多线程同时执行 --------------------------
if __name__ == "__main__":
print("==== 开始批量执行交换机命令 ====")
# 同时连接5台（可改）
with ThreadPoolExecutor(max_workers=5) as executor:
all_results = executor.map(run_command_on_switch, switch_list)
# 打印所有结果
for res in all_results:
print(res)

ok,执行成功，这样巡检是不是很方便呢，程序先搞出来，以后慢慢优化吧！今天就先分享到这里了。
