OSError: Search pattern never detected in connecthandler for aruba_os

Question

Morning everyone ,

I'm trying to write some switch troubleshooting python code's and to do that I wrote this for the test, but it dosen't work and I hope that someone can help :).

switch type : aruba 2530

python ver : 3.9.4

Netmiko : 4.1.0

CODE :

import netmiko
from netmiko import ConnectHandler
adresse = input ("donner adr")
passsword=input("donner mot de passe ")
cmd= input("donner cmd")
connection =ConnectHandler(device_type="aruba_os", ip=adr, username='admin', password=pas,global_delay_factor= 2)
print(connection.sendcommand(cmd,expect_string=r'#'))
connection.disconnect()

result :

Traceback (most recent call last):

raise ReadTimeout(msg)

netmiko.exceptions.ReadTimeout:

Pattern not detected: '[>#]' 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

Can you change as the device_type="hp_procurve" or device_type="aruba_procurve" and try check it again?
