send command "copy running-config tftp:\n %s\n\r" % Tftp_server"

Dear all,

I used the following lines to backup a configuration from cisco sw to a tftp server

        net_connect = ConnectHandler(**LoginInfo)
        net_connect.enable()
        command_ConfSave="copy running-config tftp:\n %s\n\r" % Tftp_server
        result=net_connect.send_command_expect(command_ConfSave)

it works with Catalyst switch, but when with Nexus, always facing an error as following Exception in thread Thread-2:

Traceback (most recent call last):
  File "C:\Program Files (x86)\Python36-32\lib\threading.py", line 916, in _bootstrap_inner
    self.run()

    self._target(*self._args, **self._kwargs)

  File "C:\Program Files (x86)\Python36-32\lib\site-packages\netmiko\base_connection.py", line 815, in send_command
    search_pattern))

seems the interaction between the netmiko and switch had an error, can not “#” from switch

Catalyst version 15.0(1)SE3 Nexus version 6.0(2)N2(2) Netmiko 1.4.1

My question: is there some way can help to see the realtime output from this ssh session? it may help to do some more trouble shooting on it

thanks a lot

Probably try:

    connection.send_command('copy ftp://username:pass@internal_ip/%s %s:/'%(suitable_img_file, directory), delay_factor=4)

Note, by default send_command will wait 100 seconds, so delay_factor=4 will wait 400 seconds. If you need longer than this, you can increase it to a bigger value.
