Re: How to reset the cisco switch to factory default?

When you say you were able to connect to the switch through hyperterm, were you able to login with the enable password? If not, you cannot reset the factory defaults without the enable password. If you do not have this then search on Cisco's site for password recovery for your model switch. If you did login with the enable password, the command to run for CATos is "clear config all". For Cisco IOS, you have the right command with "write erase". When you issue that command, do you get a "Erase of nvram: complete " or an error? Are you issuing the "reload" command after a successful erase? Be sure you answer No when it asks "System configuration has been modified. Save? [yes/no]:" as sometimes this seems misleading and some people think they mean to save the reloaded default. They are really warning you that you are about to loose the old configuration and attempting to prevent you from accidently erasing it. So answer "no". After a successful reload of the IOS you should also clear any VLAN information. To do this, issue "delete flash:vlan.dat" and then do another "reload".

What do I do if I forgot my password?

Well, if you forgot your password, you will need to completely reset the device to factory settings. There should be a recessed button on the back that is only accessible with a pin or paperclip. Press that and it will reset all of the settings to default.

Forgot guest pw on cisco e2500

If a password was set by user, no one else will know it if you forget it.
If the password needs to be reset to factory, so you can log in with the "default" password AND RE-SETUP EVERYTHING, then you'll need to reset the Linksys E2500 to factory defaults. You can usually do that via a special button or sequence of actions.
The E2500 manual will have specific directions for performing a factory default reset. You can download the manual for the E2500 from

Default password for a Cisco SG200-26? cisco, cisco do not work .. ??

I had the same issue after what I thought was a succesful reset. It turns out I hadn't reset the switch completely. There is a reset pin hole next to the power switch. Hold it in with a paper clip for at least 30 seconds. ( I was holding in the power button for 30 seconds.)Then you can use the cisco admin and cisco for password defaults. Hope this helps someone in the future since I spent WAY TOO MUCH TIME on it :)

Hi this works on a netgear router you could try this on you Linsky or the hair pin

Unfortunately, there is no way to recover a lost or forgotten password from a router or access point; you will need to reset the device to factory defaults. However, once the device is reset to factory defaults, you can use the default username ("admin") and password (either "password" or "1234" depending on your router) to reconfigure your router settings.


if there is a small hole in the front or back of the router push a hair pin in to reset to factory settings

hope this helps

Go to the Cisco site and download Network magic. You can use the basic version free. It has a network map that shows you everything on your network. It will give you a full version on a trial basis, but after that you can continue to use the basic.

Can't console cisco catalyst 3500

It's possible that the management port is on another VLAN or is not enabled. Your most reliable bet is to try a serial connection to console in.

Alternatively, there is a procedure that will work even if you don't know the password:
