How-to create collection based on MAC address or UUID

Hi all

I Use this collection to “find unknown” computers  for deploy OSD over PXE, to make the resource unknown i need to delete it, but I don’t know the name of the resource only the MAC / UUID that shown in the PXE boot.

First create a new collection and the member ship rules should be based on query like the images below:

 That’s it,
