Add A10 SSHDetect : Pattern not detected: 'A10DEVICE\\-Active\\-affinity\\-def\\-vMaster\\[1/1\\]' in output. #3431

romio28 · 2024-05-06T14:53:34Z

Hello,
I'm trying to add the ssh auto detect for A10 device:

"a10": {
    "cmd": "show version",
    "search_patterns": [r"Advanced Core OS \(ACOS\)"],
    "priority": 99,
    "dispatch": "_autodetect_std",
}

Command output:

A10DEVICE-Active-affinity-def-vMaster[1/1]>show version

A10DEVICE-Active-affinity-def-vMaster[1/1]>

But i recive this error:

192.168.25.15 An exception occurred:

Pattern not detected: 'A10DEVICE\-Active\-affinity\-def\-vMaster\[1/1\]' in output.

Things you might try to fix this:

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.
Increase the read_timeout to a larger value.

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

Any help please?

@romio28 Can you turn on Netmiko logging and see what it shows?

@romio28 Can you show your entire code and your entire exception stack trace (i.e. all the lines of the exception stack trace).

romio28 · 2024-05-07T10:26:24Z

debug file: test.log

Code:

`from netmiko import SSHDetect, ConnectHandler
import logging
logging.basicConfig(filename='test.log', level=logging.DEBUG)
logger = logging.getLogger("netmiko")

device = {
"device_type": "autodetect",
"host": "192.168.100.87",
"username": "admin",
"password": "admin123",
}

guesser = SSHDetect(**device)
best_match = guesser.autodetect()
print(best_match) # Name of the best device_type to use further
print(guesser.potential_matches) # Dictionary of the whole matching result
device["device_type"] = best_match

with ConnectHandler(**device) as connection:
print(connection.find_prompt())`

The problem is in the find_prmpt() function, it trying to go in enable mode, it work if I add the secret password:

The A10 driver requires enable password (as A10 requires enable mode to disable output paging and Netmiko requires this).
