Save_config to TFTP in netmiko

[kevintrankevin18241]

I want to save the startup-config to TFTP server with the class .save_config in netmiko but when i call it the server not respone. Of course I try by CLI on router : copy startup-config tftp://10.64.0.146 it works. The code is SSH to  Router OK

This is output:

R1941#
10.64.0.146
Trying 10.64.0.146 ...
% Connection refused by remote host

This is my code:

net_connect = ConnectHandler(**router)
        net_connect.enable()
        promt = net_connect.find_prompt()
        print(promt)
        tftp_server = '10.64.0.146'
        name_cfg = str('Router_' + date_backup + '_config')
        output = net_connect.save_config (tftp_server, name_cfg + '.txt')
        net_connect.disconnect()

Thank you!

Can you check on the TFTP side and see what incoming IP is seen and port?

Hi

 Where in your code you are saying this is a tftp call?

 On the command line when you add tftp:// the IOS knows that this tcp port 69. But, looking the code, I did not see any reference to the protocol only the IP address.

Hello @kevintrankevin18241;

The problem lies in the incorrect usage of the "save_config" method in Netmiko. The "save_config" method is used to save the running configuration of the device to the startup configuration, not to backup the configuration to a TFTP server.

Try with this command "send_command()"

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

tftp_server = '10.64.0.146'
name_cfg = 'Router_' + date_backup + '_config'

command = f'copy startup-config tftp://{tftp_server}/{name_cfg}.txt'
output = net_connect.send_command(command)

net_connect.disconnect()

Agree with you, I try this class with default information and the code run with the "write mem" command. I try another way by the code:

net_connect.send_command_timing(config_commands)

it work! Thankyou!
