Re: [netconf] New Version Notification for draft-tgraf-netconf-yang-notifications-versioning-03.txt

Dear Frank,

Thanks a lot for reviewing the document.

Regarding your first question. Rob Wilton pointed out the same at IETF 115 in the NTCONF working group session. The authors agree that when the subcribed xpath revision did not change after software upgrade, but the included yang modules did, that this use case needs to be covered as well. pkg-name and pkg-version from draft-ietf-netmod-yang-packages might be the best answer. We are currently reviewing that.

Regarding your second question. Absolutely. I will take that and address in the next version of the document.

Best wishes
Thomas

Hi Thomas, 

I have read this draft and I have some questions about this.

1. In section 3, Figure1 provides an example of a versioning notification. Is the version-label for stream xpath-filter? In this example, the version-label is for /int:interfaces?
  And if it's true, if the xpath expression include two or more modules, how to express this situation? 
  For example, the xpath filter is /int:interfaces/int:interface/ipv4:ipv4/ipv4:ip-addresses

2. In Section 4, I see version-labels are augmented to establish-subscription/modify-subscription ... 
  We know the YANG modules' version of a network device is deterministic, if the version-labels can't match the modules' version of devices, what is the response? Return an error?

Dear netconf wg,

We addressed in section 4.2 a copy paste error on the yang module and published the document in the -03 version.

Abstract:
   This document extends the YANG notifications subscription mechanism
   to specify the YANG module semantic version at the subscription.
   Then, a new extension with the revision and the semantic version of
   the YANG push subscription state change notification is proposed.

Dear netconf wg,

On top of the changes in the -01 version based on inputs from IETF 115 from of Jason Stern and Rob Wilton, we added in section 4.1.2 the YANG full tree view, added descriptions and resolved some issues in the YANG module raised by the YANG validation. 

On the behalf of the authors I like to request the adoption of the document to the netconf working group and request a slot at IETF 116 to present an update, discuss and conclude how to progress on subscription id being mandatory.

Best wishes
Thomas
