Sending Cisco commands from a text file using Netmiko fails. send_config_set works but send_config_from_file doesn't

Question

• I have been using this link as guide.

XXXXXX:/Test # cat test2.py
from netmiko import ConnectHandler

with open('commands_ios') as f:
    commands_list = f.read().splitlines()

cisco_D = {
    'device_type': 'cisco_ios',
    'host':   '10.1.1.1',
    'username': 'username',
    'password': 'password',
}

net_connect = ConnectHandler(**cisco_D)
output = net_connect.send_config_from_file('commands_ios.txt')
print(output)

XXXXXX:/Test # python3 test2.py

Traceback (most recent call last):

    output = net_connect.send_config_from_file('commands_ios.txt')

Answer 1

You can use readlines instead of splitlines as follows. And if ypu have a .txt > you should change it like this => 'commands_ios.txt'

with open('commands_ios.txt') as f:
    commands_list = f.readlines() #(or commands_list = f.splitlines())
    
    #commands_list = "".join(commands_list ) => If you need convert string
    #commands_list = lines.strip() => If you need remove spaces
    #print(commands_list)

Answer 2

The script works alright; commands_ios.txt file consisted of Cisco show commands which is usually entered in enable mode, send_config_from_file only enters commands in Global Config mode only hence it was throwing an error.
