Italo and all,


G.808 has a sentence about the priority in clause 3.2.8.10 as follows:

"For the case where an APS protocol is in use, an SF on the protection transport entity (over which the APS signal is routed) has priority over the forced switch."

Therefore, G.808 can be used for "signal-fail-of-protection."


For "failure-of-protocol," G.8031, G.8131 and G.873.1 should be referenced.


Best regards,


Jeong-dong

제목 : Re: [Teas] not a Yangdoctor review of draft-ietf-teas-yang-te-types-03



Hi Tom,





Regarding your comment:





"I was unclear about my comment on G808; having the reference is find but I would prefer G.808; I note that Deborah's e-mail used G.808 even when referring to the 'G808' in the I-D so I think G.808 is to be preferred."





The draft references G.808 whenever it is possible





However, there are a couple of items which are common across multiple technologies but missing in G.808:



- signal-fail-of-protection which has higher priority than the FS command



- failure-of-protocol





In this case, the set of technology-specific Recommendations (G.8031, G.8131 and G.873.1) has been referenced instead of G.808





@Tarek: I have just noted the following nit in G.873.1 reference which can be easily fixed when you publish the next draft update:





OLD



[G.873.1] "G.8131 : Linear protection switching for MPLS transport



profile", July 2014,





NEW



[G.873.1] "G.873.1 : Optical transport network (OTN):



Linear protection", October 2017,

YANG module clearly references them.. I am wondering if there is a chance or a plan to enhance the IETF idnit tool to parse the YANG module for references and silence such warnings?

Well no, that would be wrong.





A YANG module needs references, for import statements and to tell the user where to go for more information on the objects, their use and so on.





A YANG module must be plain text so cannot contain the usual HTML/XML style anchors that an I-D/RFC has.





Documents referenced from within an RFC must appear in the References of that RFC.





Hence



- anything referenced in the YANG module must be in the References of the RFC



- anything referenced in the YANG module must have a HTML/XML style reference somewhere in the RFC outside the YANG module.





Where such references do not crop up in the existing text of the memo outside the YANG module, then the practice is to add a Section X.1 before the YANG module saying words to the effect that this YANG module imports from [. and references [....





So the tool wants enhancing to generate more warnings, not less, when the contents of a a YANG reference clause do not appear in the Reference section of the I-D.





HTH





I was unclear about my comment on G808; having the reference is find but I would prefer G.808; I note that Deborah's e-mail used G.808 even when referring to the 'G808' in the I-D so I think G.808 is to be preferred.

I've moved both to informative references as per other recommendations.
