you can use password recovery procedure of your router (using confreg ) which will remove your running-config but not startup-config(nvram) . then copy running-config to starup-config and provide username and password before exit .
In both textbooks I have checked recovering a password requires changing confreg bit 6 to on by changing 0x2102 to 0x2142. But the 4 would turn on bit 7. I'm an instructor and I need to explain this to my students. Help!
Can you provide more information ? Are you using a TACACS+ server ? Do you have an access-list which is preventing the authentication from working correctly ? Is there someone at the site who can console in and remove the aaa statement ?
If you apply the aaa new-model command by accident and you are asked for a password, first see if the configuration change has been made to NVRAM if not just power down and the configuration will be wiped. If it has been saved you will have to do the recovery procedure.
