Juergen: This is good feedback on the L2 topology versus interface module.
Stating "taking out all objects that are interface specific" is a bit broad, but in principle specifics that belong to interfaces should be in the interfaces module. The L2 specification is part of a virtual topology that reflects interfaces, links, nodes, and terminating points. There will be some references to the virtual principles. Some things chassis-id imply a shared group resources (interfaces in a chassis) which creates a shared risk group. The virtual topology needs to indicate which interfaces are within a shared risk group. As Jie has mentioned, he will take into account your comments in the next revision of the draft. I have already spoken to some IEEE people about who to talk to about the LLDP yang modules. It appears the appropriate group is the 802.1 working group, and I will send a note to the chair today.

We will take a look at whether the interface model should be referenced here. > Are you saying you will take out all objects that are interface specific? I think there should be text explaining the relationship to the ietf-interfaces model and extensions of it. > The chassis-id here has the same meaning as it is in LLDP. Currently its type is set to mac-address as one common implementation. This could be updated with a more generic type. Well, it is simply under specified what it is. And there is the model of physical entities where a chassis has a specific meaning. Anyway, there needs to be more relationship sections explaining all this. But at this point, many things are simply too vague to understand what they mean and it is unclear where the information would come from. /js -- Juergen Schoenwaelder Jacobs University Bremen gGmbH Phone: +49 421 200 3587 Campus Ring 1 | 28759 Bremen | Germany Fax: +49 421 200 3103 <http://www.jacobs-university.de/> _______________________________________________ i2rs mailing list i2rs@ietf.org https://www.ietf.org/mailman/listinfo/i2rs _______________________________________________ i2rs mailing list i2rs@ietf.org https://www.ietf.org/mailman/listinfo/i2rs
