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:
- 通过 TFTP 备份到设备,就像您正在做的那样
- 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)
