The Independent Submissions Editor (ISE) comments I received June 14, 2021 were copious and detailed. Answering these comments required the addition of 13 pages to the I-D, which is now 57 pages. I have prepared a new version 04 of the I-D and submitted it to the IETF: https://www.ietf.org/archive/id/draft-rprice-ups-management-protocol-04.html You will find detailed answers to all the ISE comments at http://rogerprice.org/NUT/ISE-comments-2021-06-14.reply.html Thanks are due to Adrian Farrel the ISE editor and "Document Shepherd", who has been very helpful. As always with an RFC: "Comments are welcome". Roger
