i want to use python code for configure cisco switches

Question

I just created a python code using netmiko for cisco switches but i receive errors when i run it... i want to use the commands to go to enable mode of switch but it doesn't work...

from netmiko import ConnectHandler


cisco_Router = {
    "device_type": "cisco_ios_telnet",
    "host": "123.123.1.2",
    "username": "username",
    "password": "password"}

with ConnectHandler(**cisco_Router) as net_connect:

    net_connect.enable()
    result = net_connect.send_command('sh run')
    net_connect.disconnect()

print(result)

This is the error:

    raise ReadTimeout(msg)
netmiko.exceptions.ReadTimeout: 

Pattern not detected: 'switch' in output.

Things you might try to fix this:
1. Adjust the regex pattern to better identify the terminating string. Note, in
many situations the pattern is automatically based on the network device's prompt.
2. Increase the read_timeout to a larger value.

You can also look at the Netmiko session_log or debug log for more information.

Answer 1

One issue could be that the netmiko device_type doesn't support the OS running on the switch. If connecting via SSH isn't an option, then there are 4 telnet device_type available, namely cisco_ios_telnet, cisco_xr_telnet, cisco_s200_telnet, and cisco_s300_telnet. Try changing your device_type to one of those to see if one of those works. Otherwise, configure the switch to use SSH and try one of the many device_types that best matches your switch's OS.
