Re: Catalyst 9300 Password Recovery

Uttam,

I had the same problem as you did. In my case I found that the process differs very slightly from the 38/3650 in that instead of HOLDING the Mode button you need to press it multlple times 2-3 in my case just after it comes up with Initializing hardware.

Exceprt from documentation :

Procedure


Step 1 Connect a terminal or PC to the switch.
  • Connect a terminal or a PC with terminal-emulation software to the switch console port. If you are recovering the password for a switch stack, connect to the console port of the active switch.
  • Connect a PC to the Ethernet management port. If you are recovering the password for a switch stack, connect to the Ethernet management port of a stack member .
Step 2 Set the line speed on the emulation software to 9600 baud.
Step 3 Power off the standalone switch or the entire switch stack.
Step 4 Reconnect the power cord to the switch or the active switch. . The switch starts the boot process. Press the Mode button when it attempts to start booting. Press the Mode button 2-3 times until the switch fails to boot and goes to ROMMON mode.

Proceed to the Procedure with Password Recovery Enabled section, and follow the steps.

Step 5 After recovering the password, reload the switch or the active switch .

On a switch:

Re: Catalyst 9300 Password Recovery

As others have said the method above, marked as the answer, may not work for some. On my 9300 running Fuji 16.9.3 I had to wait for the image to begin loading and then simply press the mode button once to interrupt it.

I know it seems funny but you have to press the mode button multiple times to get bootloader mode
