After configure AAA I did not set any username!

Hi.
We have a building with 18 3550. My security manager insist in change telnet for SSH but in one of the switches I forgot to add a line with the username xxx password yyy and I activate aaa authent login def local.
So now I tryed to access the switch but I got a username/password challenge and I have no idea of the default username in that Cisco box. I tried enable and its password but it does not work.
Are there any way I connect to my switch whitout make a password recovery procedure?
Greetings

You may be able to get in through the console port still.

Thank for you idea, but it does not work. Same thing in console. I still have username/password challenge.

Did you save the config? If not, a reboot will restore it the way it was. Otherwise, you'll probably have to do the password recovery procedure unless someone else knows of another way. Good luck.
