我想自动备份我的交换机/路由器配置 cisco。

我尝试创建这个脚本:

#!/usr/bin/env python3
#-*- conding: utf-8 -*-

from netmiko import ConnectHandler

cisco_test = {
    'device_type': 'cisco_ios',
    'host': 'xxx.xxx.xxx.xxx',
    'username': 'xxxxxx',
    'password': 'xxxxxxxxxx',
    'secret': 'xxxxxxx',
    }

net_connect = ConnectHandler(**cisco_test)
net_connect.enable()

config_commands = ['copy start tftp://xxx.xxx.xxx.xxx/test.bin']

output = net_connect.send_config_set(config_commands)

print(output)
net_connect.exit_enable_mode()

但它不起作用......你能告诉我怎么做吗?

您将它们作为“配置命令”发送。在 IOS 中,必须从 Privileged EXEC 模式复制到 TFTP 服务器。如果从全局配置执行,该命令将不起作用,除非它前面有“do”,如do copy start tftp://....

您是否尝试将启动配置备份到 TFTP 服务器?顺便说一句,将配置命名为“test.bin”的有趣选择。

您可以通过 2 种方式执行此操作:

  1. 通过 TFTP 备份到设备,就像您正在做的那样
  2. 通过捕获“show run”命令的输出备份到文件

第二个选项很酷:即使您的设备无法访问 TFTP 服务器,您仍然可以备份配置。

方法一

您不仅需要发送复制命令,还需要响应您将收到的提示:

CISCO2921-K9#copy start tftp://10.122.151.118/cisco2921-k9-backup
Address or name of remote host [10.122.151.118]? 
Destination filename [cisco2921-k9-backup]? 
!!
1759 bytes copied in 0.064 secs (27484 bytes/sec)

CISCO2921-K9#

所以你必须准备好用“Enter”回答这两个问题

这是一个工作脚本的示例:

from netmiko import ConnectHandler

# enter the IP for your TFTP server here
TFTP_SERVER = "10.1.1.1"

# to add a device, define its connection details below, then add its name 
# to the list of "my_devices"
device1 = {
    'device_type': 'cisco_ios',
    'host': '10.1.1.1',
    'username': 'admin',
    'password': 'cisco123',
    'secret': 'cisco123',
}

device2 = {
    'device_type': 'cisco_xr',
    'host': '10.1.1.2',
    'username': 'admin',
    'password': 'cisco123',
    'secret': 'cisco123',
}

# make sure you add every device above to this list
my_devices = [device1, device2]

# This is where the action happens. Connect, backup, respond to prompts
# Feel free to change the date on the backup file name below, 
# everything else should stay the same
i = 0
for device in my_devices:
    i += 1
    name = f"device{str(i)}"
    net_connect = ConnectHandler(**device)
    net_connect.enable()
    copy_command = f"copy start tftp://{TFTP_SERVER}/{name}-backup-02-26-2020"

    output = net_connect.send_command_timing(copy_command)
    if "Address or name" in output:
        output += net_connect.send_command_timing("\n")
    if "Destination filename" in output:
        output += net_connect.send_command_timing("\n")
    net_connect.disconnect
    print(output)

我希望这可以帮到你。如果您还有其他问题,请告诉我
