Hello
I propose : "erase startup-config"
Or use the physical procedure :
Using Clear/Reset Procedure
1. Using pointed objects, simultaneously press both the Reset and Clear buttons on the front of the switch.
2. Continue to press the Clear button while releasing the Reset button.
3. When the Self Test LED begins to flash, release the Clear button.
The switch then completes its self test and begins operating with the confi guration restored to the factory default settings.
If you cannot start a console session at the manager level because of a lost manager password, you can clear all passwords and user names by getting physical access to the switch and pressing and holding the Clear button for more than 5 seconds. See Reset and Clear buttons
you should then be able to connect through console, with no cedentials at all.
