Again, I recommend everyone come to the Tutorial on OAM.


OAM is implemented as a sublayer above the MAC, using frames. So, exactly what would be the trouble? Passing frames?

Brad, if this isn't an invitation to get one into trouble, I don't know what is.  In any case, my input would be that we need OAM no more than 1000BASE-T does, so I'd favor leaving out of the scope of the 10GBASE-T PHY.  If someone wants to implement some level of OAM in a derivative PHY device or use MAC level OAM functions they're free to do so.


Also, from my limited understanding of 802.3ah, OAM for the PHY layer is TBD, so I don't think we can consider the work being done in EFM as useful precedence at this point.

Would you like to make a presentation to that effect? :-)


I see the Study Group as having three options related to OAM in our objectives:

1) state compliance with EFM OAM (and therefore possibly use it in our effort)

2) state that EFM OAM is beyond the scope of 10GBASE-T, excluding it from use within our effort

3) say nothing, and leave the use of EFM OAM capabilities up to those implementing the systems


Which of the three options would you prefer?


Would anyone else like to state a preferred option?

I would say that since...
        the same entity is likely to own both ends of the link
        both ends of the link are expected to be in the same building.
        both ends of the link are likely to be in the same room
that there is no need for management beyond that required for existing enterprise links.

Study group members,

As some of you may know, EFM (Ethernet in the First Mile or 802.3ah) has added Operation, Administration and Management (OAM) capabilities to their specification.  Like 802.3af DTE power, the study group needs to decide whether or not compliance with 802.3ah is within the scope of our effort, and most specifically the OAM capabilities.  This relates to compatability with our existing standards.  If there is anyone that would like to make presentations for or against compliance with 802.3ah or 802.3ah OAM, please let me know.

Thank you,

Chair, 10GBASE-T Study Group
