for 循环迭代和 netmiko 只是做第一个设备

Question

我一直在做一些网络自动化，现在我正在使用 lops 来一次不仅可以做一个，所以当我运行下面的代码时，我看到第一个路由器是成功的，但第二个路由器有错误 netmiko。 ssh_exception.NetmikoTimeoutException：读取通道超时，数据不可用。

所以我用 3 个路由器进行测试，第一个运行良好，但第二个却无法工作。

from netmiko import Netmiko
from getpass import getpass
import re

router1 = {
    "host": "10.0.0.248",
    "username": "cisco",
    "password": "cisco",
    "device_type": "cisco_ios",
}

router2 = {
    "host": "10.0.0.247",
    "username": "cisco",
    "password": "cisco",
    "device_type": "cisco_ios",
}

router3 = {
    "host": "10.0.0.246",
    "username": "cisco",
    "password": "cisco",
    "device_type": "cisco_ios",
}

routers = [router1, router2, router3]

interface_shut = list()

for router in routers:
    net_connect = Netmiko(**router)
    print(net_connect.find_prompt())
    output = net_connect.send_command("show ip int br")
    print(output)
    find_interfaces = re.findall("GigabitEthernet\d.\d", output)
    print(find_interfaces)
    for int in find_interfaces:
        interface_shut.append("Interface " + int)
        interface_shut.append("no shut")
        output2 = net_connect.send_config_set(interface_shut)
        print(output2)
        interface_shut = list() # I am doing this so the list doesnt have to have more than 3 items for each device
        print(interface_shut)
    net_connect.disconnect()    

Answer 1

那是我的错。该代码运行良好。我只是忘记在其他 2 个路由器中添加 priv 15。
