When you configure a domain name, it cannot be removed; you can only reassign a switch to a different domain.

To go back to the factory default "null" domain on IOS switches, like the 3750, you have to delete the vlan.dat file in flash. This will also delete all non-default vlans.

Switch#delete flash:vlan.dat

Delete filename [vlan.dat]?

Delete flash:vlan.dat? [confirm]

Switch#reload

System configuration has been modified. Save? [yes/no]: no

This will not delete the non-default configuration file, just the vlans, VTP domain and reset the config rev# to 0

If you want to truly go back to factory defaults (non-configuration file & the vlan and VTP information) then do the following:

Switch#erase start

Erasing the nvram filesystem will remove all files! Continue? [confirm]

[OK]

Erase of nvram: complete

Switch#delete flash:vlan.dat

Delete filename [vlan.dat]?

Delete flash:vlan.dat? [confirm]

Switch#reload

System configuration has been modified. Save? [yes/no]: no

Proceed with reload? [confirm]

Hope this helps

vtp domain null

The default is a NULL string, just blank.

try setting the domain again with no value, and it should go back to the empty, default setting.

vtp domain null

Hi,

As you can't delete the VTP domain name. There will be something name as NULL or anything else. The best practice is that change the VTP domain name from existing to another name. 

Also, you can delete the vlan.dat file. 

After changing the VTP name to any other name check the revision number must be 0.

Hello

You do this by deleting the vlan.dat file in the flash and reloading the switch, however note if this switch is connected to another switch that is actively running a vtp database then that reloaded switch could again assume the vtp configuration so disconnect it from any other switch and when it has been reloaded change the Vtp mode to Transparent.or off. before re-attaching it to the network
