Once a password has been set, is it possible to remove it from the configuration? This router is passed around to students studying for the CCNA and they don't always document the password changes correctly. We would like them to remove the passwords they have set up before logging off. We have tried using standard passwords for the students to revert the routers back to but somehow one of them always manages to input it wrong! Does Cisco allow you to remove a routers passwords (not just change it) and how?
Also, if there is an "enable Secret" command entered, it needs to be cleared with the "no enable secret", since the enable secret is used over the enable password if both are entered. The enable password is still there because some older configuration programs do not use the enable secret. The Doc link I posted earlier would be used if a student changes the password and leaves without clearing it and no one knows what it is. There is no way to keep anyone from entering a password once the get priviledged access.
from global configuration mode:
no enable password
line con 0
