Prepare the Text File
Prior to using the runCVT utility to add DHCTs to a download group, system
operators prepare a text file that contains the MAC addresses of the DHCTs that are
to be assigned to the download group. System operators can then run the runCVT
utility with the -a option, and refer to the text file, when prompted. The system will
then assign each DHCT contained in the text file to the specified download group.
