for 循环迭代和 netmiko 只做第一个设备

Question

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

所以我正在测试 3 个路由器，第一个运行良好，但第二个无法正常工作。

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。代码工作正常。我只是忘了在其他 2 个路由器中添加 priv 15。

for 循环迭代和 netmiko 只做第一个设备

for loop iteration and netmiko just doing the first device

python-3.x

for-loop
