Hello I am using netmiko to work in different vendors network. For Cisco netmiko script is working with no errors. However, for HP Aruba config_set is failing with the above error.

Here are sample of my code: function to change configuration:

def netmiko_send_config_set(device, commands):
    output = ''
    result = {}
    try:
        with ConnectHandler(**device) as ssh:
            ssh.enable()
            for command in commands:
                print("command: ", command)
                print(type(command))
                output += ssh.send_config_set(command, delay_factor=2, cmd_verify=False)
                print(output)
            return output]
    except (NetmikoTimeoutException,
            NetmikoAuthenticationException) as error:
        with open("errors_001.yaml", "a") as error_dst:
            result[device['host']] = error
            yaml.dump(result, error_dst,
                      default_flow_style=False, sort_keys=False)

function call:

netmiko_send_config_set(device, ['logging host 1.2.3.4 transport udp port 5054'])

Why question: what am I doing wrong (just to mention same code works for cisco devices with no issues)?

I have been using the netmiko module for these HP switch modes: Aruba 2530 48 PoE+ 2SFP 2Gbe J9778A: Aruba 2530-8G J9777A: Aruba 2540 48G 4SFP+ JL355A:

I have used device_type: aruba_os for all of them

so, I will try switching device_type: hp_procurve
