Re: Close TCP Port 23 - Telnet 3COM 5500-EI
Thank you very much for your answer.
It didn´t work. Or, I didn´t know how to do it.
When I tried it :
<5500-EI>system-view
[5500-EI]telnet server disable
^
% Unrecognized command found at '^' position.
Is there any other way?
Thank you very much.

Which options the telnet server command have? check with Tab after writing telnet server at prompt once in system-view mode.

Re: Close TCP Port 23 - Telnet 3COM 5500-EI
At this point I wonder if we're speaking about the same matter...so, could you provide sanitized (no S/N or private references) outputs of:
- display version (and eventually also display device manuinfo)
- display current-configuration
commands?
Thanks.
