All – in reviewing the comments and proposing responses, I noticed several areas that need attention. Having only a small number of people look at these doesn’t really build consensus. Please take some time to consider and discuss – on
the reflector – the following topics & comments. If you do start discussing these, I would suggest you start a thread with the subject: “d2p1 Subject – X” where “X” is the subject in the below, or some other fitting description. Others can follow suit.
From my perspective, the following stand out:
- D-PLCA & PLCA – resolving the state diagram issues. It seems that a number of the changes that we put in have rippled through multiple state diagrams. Patching them with comments
may not be the best course. Some discussion on what we really need and whether we can simplify is in order. See comments 36, 68, 105 & 106, as well as 299 (unsat), and 323 (satisfied) on D2p0.
- Type 0 / 24 V power – this is the general issue of what does type 0 need to do. We are balancing regulatory positioning (whether 24V power needs to be 24V or whether it can be a bit
over and be ‘24V nominal’) vs. utility (how much power we can provide to how many nodes). After that the numbers ripple through the spec. These are generally the specifications in Topic “Power”, but a couple “Unit Load”, and one “Mixing Segment”. See comments
60, 84, 87-97, 99, 100.
- LLDP & Management (particularly of power) – we had an ad hoc on this, and have a rather substantial presented solution for each. We didn’t have that much participation in the ad hoc.
We know what a few people think – do others care? Is this going to be a source of more comments because people are going to start adding items or specificity? Let’s try to get it contained now. Please review the contributed text as well as the comments –
there’s a lot in there, and what is in the draft in those spaces is only there as informative. See comments 17, 64, and 65.
- Mixing segment, Unit Load, and power on conductors without data – we have some tweaking going on with requirements. We need to understand the impacts and benefits. Various issues
here. Mostly “Mixing Segment”, “Unit Load”, and “Late” comments, but also a few “Power”, and even a few “EZ”. See comments 12, 24, 33 (EZ), 35, (37 & 61), 58-60 (EZ, + 60 is Power), 88, 113, 114, 116, and late comments 118, 121, and 123, as well as 2p0 unsatisfied
317.
Then there are still the (technical) Items with unsatisfied comments from last time. We don’t have many comments on these:
- Relationship to 10BASE-T1S / naming (d2p1 comment 111, d2p0 unsats: 188 & 192)
- Jabber (d2p1: 57, 72, 73 d2p0 unsat: 24 & 25)
- Testing (d2p0 unsat: 74, 77, 80, 82, )
There are also various editorial unsatisified comments on d2p0 that we should consider closing. Please review the unsatisfied report.
