I must be blind today because I cannot find any information about this. Can someone point me in the right direction?

Re: Catalyst 9300 Password Recovery

Cory,

It is the same as Catalyst 3850.

Power cycle the switch. Immediatly press and hold the Mode button. Hold the button till the Status LED will go amber. Then on the console you should be in Boot Loader.

Switch:

Add the following variables.

Switch: SWITCH_IGNORE_STARTUP_CFG=1

Then boot the switch.

Switch: boot

Once the switch has booted you can copy the saved config back into the running config.

Switch# copy start runn

Next set your password(s). Finally we want to remove the variables we set while in Boot Loader.

Switch# no system ignore startupconfig switch all

Save your new config.

Switch# copy runn start


Let me know if you have any further questions.


Regards,


Minhaj Uddin

Re: Catalyst 9300 Password Recovery

Pressing and holding the mode button does nothing for me, i have read other threads and the solution that has worked for me is after power cycling the switch just start pressing the mode button multiple times until you see "switch:"

Re: Catalyst 9300 Password Recovery

You must be running IOS XE (linux), in that case it's a little different, follow these steps:

Initializing Hardware...

System Bootstrap, Version 16.6.1r [FC1], RELEASE SOFTWARE (P)
Compiled Sat 07/15/2017 8:31:57.39 by rel

Current image running:
Primary Rommon Image

Last reset cause: SoftwareReload <---- Once you see this, start pressing and releasing the mode button 3 times
C9300-24U platform with 8388608 Kbytes of main memory

attempting to boot from [flash:packages.conf]

Located file packages.conf
#
#####################################################################

Unable to load cat9k-rpboot.16.06.02b.SPA.pkg
Failed to boot file flash:user/packages.conf
ERROR: failed to boot from flash:packages.conf (Aborted) <--- will abort
switch:
switch: <---- ROMMON

Now issue these commands: 

 

Switch: SWITCH_IGNORE_STARTUP_CFG=1

 

Then boot the switch.

 

Switch: boot

If it shows you error issue the same "boot" command again.

Thanks

Re: Catalyst 9300 Password Recovery

Earlier procedure of continuously pressing the mode button didn't worked. This one described by

Ciscoguy007procedure of pressing mode button 3 times, worked for my C9300-24T device.

Re: Catalyst 9300 Password Recovery

Your answer is wrong. The correct way to password recover a Catalyst 9300 is here:

 

https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst9300/software/release/16-6/configuration_guide/sys_mgmt/b_166_sys_mgmt_9300_cg/b_166_sys_mgmt_9300_cg_chapter_01100.html#task_nzq_q4z_n1b

 

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. As soon as the System LED blinks, press and release the Mode button 2-3 times. The switch enters the 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:

Switch> reload
Proceed with reload? [confirm] y

On the active switch:

Switch> reload slot <stack-active-member-number>
Proceed with reload? [confirm] y

Step 6

Power on the remaining switches in the stack.

Re: Catalyst 9300 Password Recovery

I'm in the similar situation in which I rebooted several times and finally received the switch: onto my console. I've been unable to type anything but the boot process was interrupted. Please provide me any information if possible

 

thanks

Re: Catalyst 9300 Password Recovery

Thank you so much, this is correct! The old way of holding down the mode button was not worked for me and I was stumped.

Re: Catalyst 9300 Password Recovery

This is a pretty important process to remember because it is almost inevitable that a Catalyst  Admin will need to perform this process. It also works on Catalyst switches it is super useful '

Re: Catalyst 9300 Password Recovery

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.
