If you are running CatOS al you need to do is run "clear config all"

you do not need to reload the switch to make the changes.


If you are running IOS then you will need to run "write erase" and then "reload"

When prompted to  save changes answer "no" and confirm the reload and you will be good to go.

Now if you need to reset vlan information then you will need to delete the vlan.dat file

dir flash
delete flash:vlan.dat

 and the reload your switch



here is a link that gives a little more info on this

"write erase" will not clear the vlan database. When the switch comes back up, it will still have the vlan list and any VTP information.
