I have found password recovery procs for the route processor of CatOS (6500) but not for the switch processor. Would they be the same if I do the break sequence before it says 00:00:03: %OIR-6-CONSOLE: Changing console ownership to route processor.
The password recovery for the SP is different than the password recovery for the RP, here you are the one for the SP:
Take care that you have a window of 30 seconds to do it, i failed it the first time i tried it, try using a simple password at first may be a single letter password or simply a null.
HTH, please rate if it does help,
