Thank you so much. After an upgrade, my credentials went AWOL. Thanks to your detailed video and instructions, I don't have to worry about not being able to logon to my 3850 stack. I will sleep, tonight.
this is probably the most important step. 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.
Hey, I'm quite new with cisco routers and this maybe an stupid question but how to i get to use the console? like I have a PC with serial port and all but what do i need to download to be able to use the cisco console? Knowing that would really save my life lol
I would get started with putty or a similar application. Search for "how to connect to a Cisco console port" and there will certainly be a few videos to get you started
Hi, I've followed your guide and I'm unable to go into configure terminal after I copy startup config to the running config. Any suggestions? Thank you
You need to change the passwords, etc immediately after doing to copy to ensure you can get back in. Username/ passwords as well as enable passwords will need updated.
Hello brothers, how do I reset 2 units, Catalyst 3750 Series, which are connected together, without changing the configuration? Thank you, best wishes.
it shows these files xmodem[0]: (read-only) null[1]: (read-write) bs[3]: (read-only) flash[18]: (read-only) tftp[19]: (read-write) when i enter dir what command do i use to delete them
I’ve been trying this and I get stuck at creating a new password. Right after copying the startup to the running config, I’ll try to make a new password and it says invalid input with the marker on the first or second letter. any ideas?
Hi, if anyone who knows anything about the 2960x I could really use some help. I think its beginners blues. Im trying to take a second-hand unit and reset it. I have been trying for almost 2 weeks at this point. It has to be possible, right?
@TheTechCatalyst Thanks for responding. I figured out Express Setup was doing something weird. Everything came up after setup through CLI. Where can I find information on how to use this properly? My main goal is to hook a Rukus Zone Director to it and run about 10 APs throughout my home. It would be nice to have my IOT devices on a subnet without internet access and I don't know where to start.
hi PLEASE I HAVE THIS CISCO 3650 SWITCH . PLEASE HOW DO I DELETE THE FILES . IT HAS A USERNAME AND PASSWORD. CISCO WS-C3650-48FQM-S . WHAT DELETE COMMAND DO I USE?
hi dear can you support me tio fixing my issue i have cisco catalyist 9300L-4G-A and i missing my IOS File , so how can upload the ISO FIle to the switch
Its works but when i want activate the "EXEC" mod i have a beautiful "acces denied" with the same password , i am a noob on switch, i just want reset the switch in factory default :\ Any ideas ?
My config file has the username and password built in. Once I go through these steps minus setting a username and password, I get back to where it's time for me to log in and I can't log-in. Any one have a solution?
SWITCH_IGNORE_STARTUP_CFG=1 Is this command case senstive ? I tried many time using this command ..... but its not working .... again and again booting with startup config Plz help.me out
Did you end up getting that sorted ? The command does not work for me as well even though I am copying it and pasting it from a website including the case ? its like I am not even inputting the command as the switch boots up normally with the old config
Your instructions were better than what the Cisco engineer gave me...worked, thank you so much!
Thanks!
Mate you really saved me. For some reason our Catalyst lost the user. It didn't exist anymore. This finally gave me a chance to restore it.
This method also works for a C9400. Don't forget to remove the standby SUP before performing the boot. Awesome tutorial.
Thank you so much. After an upgrade, my credentials went AWOL. Thanks to your detailed video and instructions, I don't have to worry about not being able to logon to my 3850 stack. I will sleep, tonight.

Totally just saved me an hour of work. Remind me to buy you a beer if we ever meet. :)
Haha You bet! In luie of a beer keep my new company in mind if you're company ever needs internet bandwidth... fullspansolutions.com
this video literally saved my life!! thanks a lot @the tech cataylsy !!!
Thanks!
I believe that 9300's have two great features (same as the 3850s) Dockers and Per Port Packet Captures :)
Thank you! it worked in stackwise configuration
Glad to hear it!
Question: How about for switches in stack, what is the initial process? Should i on/off all ? or keep members turn off and do off/on Master?
Shutdown the switches and disconnect the stack
Thank You Friend, It Was Very Helpful, Greetings From Chile 🇨🇱
Thanks!!
Thank you, man! You helped a lot and saved my nerves 👍
If there were 2 or more 9300's in a stack, how would the procedure be different (if at all)? Would you perform this on the master?
Work this process on the master. :-)

These were awesome,thanks for sharing this information.
Thanks for stopping by to check it out. Happy Networking!
Thank you! You saved my time!
Never fun to have to recover. Glad it helped!
does this method work for cisco switch Catalyst L3 WS-C3850-24T ?
It should... Good luck!!

@@TheTechCatalyst yeah, but i cannot go into configure terminal once i copy startup config to running config
@@ziqex I would copy the startup config to TFTP, etc and go through it line by line to figure out why and remove what's preventing you.

If you reset like this you then load the existing configuration and reset the password. Configuration is saved.
it shows these files
xmodem[0]: (read-only)
null[1]: (read-write)
bs[3]: (read-only)
flash[18]: (read-only)
tftp[19]: (read-write)
when i enter dir
what command do i use to delete them

I’ve been trying this and I get stuck at creating a new password. Right after copying the startup to the running config, I’ll try to make a new password and it says invalid input with the marker on the first or second letter. any ideas?
Did you do a "config t" before attempting to change the password?
i try this comman,but not work for me, my device hasbeen reset to factory,how to enter to roomon for boot again ?thanks

@@braddofner I would look into how to configure VLANs on a catalyst switch.
Im struggling on how to configure the web interface.
Please share commands
If you would like to just wipe the switch type "factory-reset all". This will erase everything in the switch flash, including the firmware.

How it will help in case of console password?
This will also allow you to clear console passwords as you are preventing the loading of the startup configuration all together.
At minute 2:0 of the video, when I give the configure t command, I get an error. % AUTHORIZATION FAILED
I would confirm the prior steps. It sounds like the switch may have booted with the prior config vs booting without one.
@@TheTechCatalyst Correct, everything was done following the steps mentioned
@@TheTechCatalyst No, I start the explanation from your video
Thank... is really... saludos desde Chile
С9300 Which buttons and how to reset to factory settings if there is no monitor. Only the device.
Sorry, you have to use this process unfortunately.
hi dear can you support me tio fixing my issue i have cisco catalyist 9300L-4G-A and i missing my IOS File , so how can upload the ISO FIle to the switch
You can get the software from Cisco TAC or your cisco account team
In my switch, password recovery mecanism is disabled then how can i reset password..
Its works but when i want activate the "EXEC" mod i have a beautiful "acces denied" with the same password , i am a noob on switch, i just want reset the switch in factory default :\
Any ideas ?
Thank you for the video, Thumbs UP👍.
Thanks for watching!!
My config file has the username and password built in. Once I go through these steps minus setting a username and password, I get back to where it's time for me to log in and I can't log-in. Any one have a solution?
You have to boot the switch, load that config and them immediately issue the command to update the username and password to a known value.
very helpful many tahnks
can i use the GUI on these?
You can, however I don't believe you can reset the password via GUI. Check out the video of the GUI here: ruclips.net/video/fypSTGxglRw/видео.html
Thanks
And again you help me! :)))
Thank's a lot!
You're welcome!
Thanks!
Thank you
Thanks bro. I Love.
SWITCH_IGNORE_STARTUP_CFG=1
Is this command case senstive ?
I tried many time using this command ..... but its not working .... again and again booting with startup config
Plz help.me out
Probably.
Did you end up getting that sorted ? The command does not work for me as well even though I am copying it and pasting it from a website including the case ?
its like I am not even inputting the command as the switch boots up normally with the old config
I believe it is. I did this 2 times just now and the first time using all lowercase didn't work. Used cap letters and now i'm in!
SHOOT. Lifesaver! Thanks!! :)
well the password didnt work, changed it three times per this video and no dice
