@Aadasrh It looks like you are failing to go into enable mode.

Probably need something like:

from napalm import get_network_driver
driver=get_network_driver("ios")
optional_args = {'secret': 'your_secret'}
connection=driver(hostname="192.168.0.5", username="aady", password="cisco", optional_args=optional_args)
print("opening")
connection.open()

@ktbyers Hello sir,

it is working fine you were correct the program was not able to go into enable mode i changed the user privilege level on router and it is working now.

one small doubt i have before doing this change i also made a simple Netmiko script to check my SSH and ran a command as so how did it work .

Did it run the command without going to enable mode.

Below is the netmiko program that was working without making any changes to user privilege.

from netmiko import ConnectHandler
cisco_881 = {
'device_type': 'cisco_ios',
'ip': '192.168.0.5',
'username': 'aady',
'password': 'cisco',}
net_connect = ConnectHandler(**cisco_881)
output=net_connect.send_command("show ip int brief")
print(output)

@Aadasrh Yes, 'show ip int brief' does not require enable privileges so in the Netmiko case it worked as is.
