Jeffrey, Lots of thanks for a prompt response. I tend to agree with your statement that " IETF doesn't have a useful OAM model". But I would add that, in spite of that, IETF has a rich set of OAM tools that are widely deployed and serve the real needs of the IETF community reasonably well, and from time to time adds to this set when new issues are identified.
Whether a useful OAM model is really needed in his situation, or not, is, IMHO, a matter of personal preferences. "If it is not broken we don't fix it".

I think that's a mis-characterization. Bidirectional Forwarding Detection (BFD) on Link Aggregation Group (LAG) Interfaces https://tools.ietf.org/html/rfc7130 IEEE wasn't really interested in having BFD running native. Much of this has to do with the OAM and layering models that IEEE has for Ethernet. And yet, IETF was getting push to solve at least a problem relating to layer 3 issues for traffic balancing over LAGs. That was somewhat out of the realm of IEEE. So, while it took us a while to frame the problem, we eventually found a place where we were able to solve our respective problems without stepping too much on organizational and layer-wise boundaries. > At the same time I think there is a difference in the overall attitude with > regard to OAM between IETF and IEEE 802.1. I think I would state this as "IETF doesn't have a useful OAM model". Many people would prefer us to have one, and see BFD as a useful component for it. However, that's bigger work than just BFD. -- Jeff ___________________________________________________________________________ This e-mail message is intended for the recipient only and contains information which is CONFIDENTIAL and which may be proprietary to ECI Telecom.
