Getting Started:

Import module

import datetime
import os
import re
import netmiko
from netmiko import ConnectHandler

Login information

my_device = {
        "host": "192.168.xxx.xxx", #cisco 2811
        "username": "xxx",
        "password": "xxx",
        "device_type": "cisco_ios",
        # "global_delay_factor": 2,
    }

Start timer and connect network device

starttime = datetime.datetime.now()
net_connect = ConnectHandler(**my_device)
net_connect.enable()

Enable Cisco "privileged" mode use "send_command" function and find expect string

If you want to use global mode that you will use "send_config_set" function.

# cmd ="copy running-config tftp:/192.168.xxx.xxx/BackUp_cisco_2811_config"
cmd ="copy running-config tftp:"
result = net_connect.send_command(
    cmd,
    expect_string=r'Address or name of remote host',
    )
    # Address or name of remote host
    # Destination filename
result+=net_connect.send_command("192.168.xxx.xxx",expect_string=r"Destination filename")
result+=net_connect.send_command("R1_config",expect_string=r"#")

Show endtime and disconncetion

endtime = datetime.datetime.now()
print("total time: {}".format(endtime - starttime))

net_connect.disconnect(
