Completely Clearing a Cisco Switch…The Easy Way!
Clearing out a Cisco switch configuration is always a pain because VLANs are kept in a seperate file from the startup-config (NVRAM). There's two ways to clear a switch back to the factory defaults – the easy way and the REALLY easy way:
The easy way –
Switch# write erase
Switch# delete flash:vlan.dat
Switch# reload
The REALLY easy way –
Hold the "mode" button on the front of the switch for 10 seconds. The lights will blink then go solid – the switch completely wipes all configuration and then reboots. Obviously, this method only works on stackable switches as the chassis based switches do not have mode buttons.

what about formatting from ROM 😉 ….
Holding the mode button will not delete the vlan.dat file, but you can delete it manually by typing:
cd flash:
del vlan.dat
will the “mode” button delete vlan.dat as well?
