DETAILED DESCRIPTION OF PROBLEM:
Definition of DPoE Version Number TLV, included in C.9.1 in DPoE-SP-MULPIv2, makes reference to 802.3
OAM INFOPDU, specifically, to the “TLV type 0xEF”, which supposedly “refers to Info TLV extension”. Closer
inspection of the content of Table 57–6—Information TLV types, in IEEE Std 802.3-2012, indicates that the proper
code point for Organization Specific Information TLV is 0xFE and not 0xEF as provided in the published
MULPIv2 spec.

There are also further wording inconsistencies which need to be corrected to better describe the Information
OAMPDU and DPoE extended Info OAMPDU. The current wording is at best unclear, and at places, technically
incorrect.
Furthermore, there is no specific text describing mandatory requirements for the DPoE System to use the values
polled from the DPoE ONU to populate specific DHCP TLVs sent by the vCM. There is only informative text,
leaving it open for implementers to use arbitrary values, should they choose to do that. Once the text is clarified, as
proposed, it is also not necessary to repeat in each and every DHCP TLV that the value for this parameter is
retrieved via OAMPDUs and TLVs.
