I've added Tissa to the cc list above. I believe that for now he wants to be listed with "Consultant" as his affiliation and with email address <tsenevir@gmail.com>. The IETF LC ends the 13th, in a few days. I suggest that you update the contact info for Tissa, spell out OAM, and update the MODULE-IDENTITY, since those don't seem like they would be controversial. For any changes to the Security Considerations text, I suggest you post proposed text in this thread before editing it in. Thanks, Donald (Shepherd) ============================= Donald E.
