I recently used this to recover the password on my test switch, a Catalyst 6509.
This will work on the following switches:
Catalyst 2900
Catalyst 2900 Series G
Catalyst 2926
Catalyst 4000
Catalyst 4840G
Catalyst 4908G-L3
Catalyst 5000
Catalyst 5500
Catalyst 6000
Step-by-Step Procedure with examples:
1.Attach a terminal or PC with terminal emulation to the console port of the switch. Use the following terminal settings:
9600 baud rate
no parity
8 data bits
1 stop bit
2.Turn off the switch and then turn it on.
! Important You must complete steps 3 through 7 within 30 seconds after you turn the switch off and on and the first time you see the password prompt.!
3.Press Enter at the password prompt to enter a null password.
