Password problem on Catalyst 3750

Hi all,

I am an Unix administrator and we lost all account and password informations to connect on a Catalyst 3750 switch.

Is there a way to connect to the switch (With a serial cable?) an to create a new account without losing the configuration ?

Thank's for your reply.

Regards.

Thank's Robert,

I find this method but the switch is running and I don't want to reset the configuration of the switch.

Is there another solution ?

Regards.

This method won't reset the configuration.

During the boot process, you rename the current configuration so it doesn't get loaded.

rename flash:config.text flash:config.old

When  the switch boots, it loads a blank image. Then you rename the config  file and load it into the running config and you can change the logon  credentials to something you know.

It's important that you follow the steps exactly so you don't lose the configuration. Password recovery is a pretty common procedure.

The  only other method of recovery is if you have a copy of the current  running configuration. Send me a private message if you have this config and we can discuss the possibility.
