The behavior that you describe is exactly correct if your session is on the console port. The symptoms sound like this session is a telnet session. In a telnet session you get the error message about no enable password if you attempt enable but no password has been configured. Swee the solution to this issue is to login to the 2600 on the console port, go into enable mode (which as Michael suggests would work just fine) and configure an enable password.

Hi Rick


Once again thank you for the information provided in your post.


It is very rarely that I would telnet/ssh directly into a router or switch. Most of the time I connect via console/terminal servers to the consoles of the devices. From my home lab and my studies I am familiar with the error when I attempt to telnet to a router/switch which does not have a password configured on the VTY lines. I have never come across the error shown in the initial post.


This will be one of the new things I have learned today and is worth the rating.


Best Regards & again thanks a million,


Michael

In many of my customer engagements remote access to routers and switches is frequent and important. I have seen the error when there is not a password on the VTY lines more frequently and the error when there was no enable password when telnetted I saw more often when I was actively teaching Cisco courses.


I am glad that my answer was helpful to you. Thanks for the rating.


I am glad to see that you continue to be active in the forum. Keep up the good work.

This symptoms came out from console port, not telnet session. I was unable to go into enable mode from console and configure the enable password.


1 more question. When try to set passwors on cisco router 1700? It gave me the message below:


cisco1700#enable password [email protected]

%Invalid input detected at ^ marker


Anything wrong with the command?

Hi, ssweehin


For the 1700 router, type "config t" first, then type "en password password". It should work.


For the 2600 router, please post the output of "sh user" and "sh line".

If it was not a telnet session then is it possible that you were connected to the AUX port instead of the console port? I have seen the symptom that you describe on telnet and on AUX but I have never seen it on the console.


If you try and it happens again would you do the show users command and post the output?
