Password Recovery on 3850

[Christine_Lane]

I am attempting to do a password recovery on a 3850 switch stack running 03.06.05E.  When I bring up ROMMON I cannot enter the command SWITCH_DISABLE_PASSWORD=0 because it is read only.

I attempt to bring up express setup because whenever I reboot it brings up the existing configuration which I cannot enter into.

How do I blow off the existing config so that I can re-enter it in?

I managed to get in.  The steps that I took were:

Power cycle the switch and hold down the Mode button until it brings you into ROMMON.

Enter in the command switch: SWITCH_IGNORE_STARTUP_CFG=1

(This doesn't seem to work since it still continues to load the config with the unknown passwords.)

Enter the command switch: boot flash:packages.conf

Let the system reboot.

It will come up with the prompt for entering the initial setup.

Press n for NO

This places you into a blank config and from here you can proceed with the normal password recovery (i.e. copy the startup config into running config and change the passwords).
