    Hi,

    Is there idea to log of the case of layer 2 loop. I can see the case of layer 2 loop when it is occurred by using "show ethernet-switching table", and it shown by the listed MAC address with often changing the source of interface. But I unable to catch the evidence. Is there any way to log the event message? Or perhaps any of traceoption configuration to do?

    'show ethernet-switching mac-learning-log' command will show the mac moving between interfaces.

    Is there any log file generated by such messages?

    Thank you, maybe I would take that as the best answer. Perhaps if anybody would know to generate a log file, let me know how.
