Hi Benoit,

[SC>] 
[SC>] Thanks for pointing to this document  (Problem Statement, Usecases and Requirement on management of constrained nodes).
This is definitely a good start in understanding the problems and requirements.

>> Disclaimer: maybe this draft was mentioned already. I'm not following 
>> the 6lo mailing list.
[SC>]  No, it is not currently listed in the milestones update.

[SC>] 
[SC>]  It is listed in the 6lo listinfo and proposed milestones for discussions.
              Of-course 6lo WG would decide if we want to define MIB only document and/or interfaces.

That's actually my point. Should we focus on developing a MIB module, taking for granting that SNMP is THE way to manage constrained nodes? Or should we ask ourselves: based on the collected management requirements, let's see what is more appropriate?
You know, like I2RS is currently doing, instead of jumping to NETCONF/YANG directly because it seemed like the solution.


[SC>] We should discuss the scope of  management interfaces work in the wg meeting. Restricting to SNMP is certainly has its limitations.  Management configuration and reporting parameters requirements and Interfaces are important.  Personally, I'm in favor of a common architecture for the management infrastructure as much as possible for the 6lo devices and then leave hooks for L2-technology specific information.

Best regards,
-Samita
