Resetting a Switch to Factory Settings

Yes.

Depends ... if you have the passwords for the switches you may use write erase and reload

If not you will have to reset the switch at boot-time.

Search the cisco web site and you will find some tons of docs about that.

In all cases you need a console cable.

If they are 2950 or (2960 - these are the current model.) Not -XL at the end.

You need to - connect up console log in if necessary go to enable mode with the "enable" commmand "write erase" - this is the old command and there is a more descripitvely named one as well. but I dont know what it is. "reload" - or just switch off

Was there a 2900XL series? If it is one of these then the above may work or it may be different. I forget.

If there are passwords and you dont know them you will have to do password recovery first. Search the cisco web site for the words

"model-no" password recovery

This should turn up the correct document.

erase startup-config

also, delete flash:/vlan.dat to clear the vlan database.

This should work with most, if not all, of the IOS based switches.

yes. the same procedure should work.
