Catalyst 9300 Password Recovery

[cory.smith@rsmus.com]

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

"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:"" 

This works, break command no longer gets you into rommon.

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

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.

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

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.

[DarylHigginns1632]

did this, now I it wont prompt for password. startup config is correct with passwords, run config is default. Try copy start run, wr mem but does not stick on reload.??

hi,

Guys. I was in process of IOS upgrade of my production stack. primary device got upgraded, secondary device shwoed version mismatch error once, then showed secondary switch was in provisioned mode but did not boot & went in rommon.

I tried to copy ios from usb, it did not allow. even tried to use set variables but no success. switch is still in rommon. Now I have disconnected it and have brought out of production.

please share steps to recover from this & add in stack again.

Thanks in advance.

Did you add the auto-copy option to the end of the install command? It is unusual that you could not copy from USB though, what was the error you received? Make sure the 'software auto-upgrade' command is present on the master and then reconnect the member and then power on.  You may need to downgrade the master to match the member and start from scratch.

Just some ideas off the top of my head.

Switch: SWITCH_IGNORE_STARTUP_CFG=1

is that command case sensitive ? 

[SatriaRadi30]

are these guide will to erase/default all config or just a reset/recovery password?

previously many thanks bout for the guided.

Hi Minhaj Uddin,

What if the switch is stacked? Do we need to remote the switches from stack first? or assign master to another member?

Many thanks.

You do not need to break the stack.
