Exactly, different layer may have different addressing schemes. But I am wondering which layer the flow entropies are applied? L2, L3, MPLS layer?

I am aware of that, but this is different, MEF YANG model is specifically for Ethernet and structure does not allow to bring different addressing schemes other than MAC address. Additionally the proposed standard allow to add flow entropies and facilitate nested OAM between different technologies. You may have to read in to the details to see the actual differences.

Tissa, Greg, all

Metro Ethernet Forum has already standardized Yang Modules for Ethernet Service OAM Performance Monitoring and Fault Management. Please see MEF 38 and 39

Yes it is, generic YANG model steup the base framework. It can be extended to add tools as well as other elements as well technology deviations. Alarms etc either be part of this document will be a separate document that specifies them. That is the reason we have designed the model as modular as possible and extensible as possible.

Please let us know if any of the parts are not extensible or not modular enough.

Hi Tissa, authors, et. al,
I've read documents and would like to clarify scope of these documents. OAM is not limited to ping and traceroute functions. It even not limited to continuity check. And in connectionless networks there would not be connectivity verification. And the performance measurement is the big part of OAM as well as protection coordination, defect alarms, and etc. Hence my question, is it in plans of the authors to address all of OAM in respective documents?

We have published YANG model for OAM. #1 draft below place the generic framework for OAM, that can be augmented for different technologies. #2 and #3 are application of the concept to NVO3 and TRILL,
