Tip: When you use the EXIT or LOGOUT command at enable mode, it will exit you from enable mode as well as terminates your session. As a result, it will clear the history buffer as well. If you wish to go to user exec mode without terminating the session, use the DISABLE command at enable mode.

Router# disable
