netmikoのエラーについて

Question

実現したいこと

• YAMAHAのRTX1200にPythonライブラリであるnetmikoを用いてconfigを適用する。

現状

CISCO機器に対してはenable()で特権モードになりconfigを適用できるが、YAMAHA機器ではenable()で特権モードになった後から進まない。

発生している問題・エラーメッセージ

enable()でエラーが出ています。

Traceback (most recent call last):
  File "C:\Users\user\netmiko\yamaha2.py", line 29, in <module>
    net_connect.enable()
  File "C:\Users\user\anaconda3\lib\site-packages\netmiko\yamaha\yamaha.py", line 28, in enable
    return super().enable(
  File "C:\Users\user\anaconda3\lib\site-packages\netmiko\base_connection.py", line 2008, in enable
    output += self.read_until_prompt()
  File "C:\Users\user\anaconda3\lib\site-packages\netmiko\base_connection.py", line 812, in read_until_prompt
    return self.read_until_pattern(
  File "C:\Users\user\anaconda3\lib\site-packages\netmiko\base_connection.py", line 721, in read_until_pattern
    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.

pattern: (\#|>)


This can be problemtic when used in read_until_pattern().

You should ensure that you use either non-capture groups i.e. '(?:' or that the
parenthesis completely wrap the pattern '(pattern)'

Answer 1

この回答はGPT-4による自動生成回答です

YAMAHAのRTX1200では、特権モードに移行するためのコマンドがenableではなくadministratorであるため、enable()メソッドを使用するとエラーが発生します。

そのため、send_command()メソッドを使用してadministratorコマンドを送信し、特権モードに移行することが可能です。

以下にその例を示します。

from netmiko import ConnectHandler

device = {
    'device_type': 'yamaha',
    'ip':   '10.0.0.1',
    'username': 'admin',
    'password': 'password',
}

connection = ConnectHandler(**device)

# 特権モードに移行
connection.send_command('administrator')
connection.send_command('password')  # administratorのパスワードを入力

# ここから設定変更等のコマンドを送信可能

このように、send_command()メソッドを使用して特権モードに移行することで、設定変更等のコマンドを送信することが可能となります。
