[CCAMP] 答复: YANG Alarm Module in CCAMP?

[Zhenghaomian <[e-mail]>]

Hi, Stefan,

Thank you for bring the draft and the document, please find some of my comments as follow:


1)      I agree this work is useful, i.e., to have a generic alarm model draft in NETMOD. We had a draft on related topic as https://tools.ietf.org/html/draft-sharma-netmod-fault-model-01, unfortunately I have not got a chance to  compare the gap between this draft and yours, did you notice this draft?  And any comments?

2)      I am confused with your 2nd comment in the following email. When you said  ‘We will have a problem if different technologies will define different alarm-modules.’, IMHO I have an opposite opinion, if different technologies are using same alarm-modules, that would be a trouble. I understand there is a lot of common stuff among different technical alarms, but it is an adventurous assumption to restrict any tech-specific work. Could you confirm on this?

3)      If there is any tech-specific alarm work (may not be much), especially for L0/L1/microwave, that would belong to CCAMP. It is also difficult to conclude now whether it will be defining additional identities or model augmentation.

My 2 cents,
Haomian

Hi All!
Thanks for reading the doc.
A couple of comments:
1) I personally agree it fits in NETMOD, but the discussion in NETMOD said we would get much more relevant input in CCAMP since there is more alarm expertise in this group. So this is circular :)
2) I do not really agree when you say "extend it with technological aspect”, “optical alarm Yang should be in the scope of CCAMP” requires a dedicated CCAMP YANG module. The tech specific alarms are “alarm types” according to the alarm-module. Those are defined as YANG identities. So the tech specific part is “only” defining the corresponding identity. No real model here, just the identities. We will have a problem if different technologies will define different alarm-modules.
3) To Petch point on "I am conscious of how much time I spent on Sharon's SMI versions, which I did not then see in the wild”.
Same here :) I took part of a couple of implementations as well.
And that is one of the main reasons why I think an Alarm YANG is critical. Why do we not see the IETF Alarm MIB in the wild?
* It came too late, all devices had proprietary ways of reporting alarms (if devices had a notion of alarms at all….). Lets do an Alarm YANG now to avoid that problem.
* Since it had to add on top of existing MIBs it became a complex alarm mapping MIB (Mapping existing notfs into an alarm model) rather than an alarm MIB. That made it very complex.

Here is a presentation

Hi Daniele and all,

Yes, I agree with you.

As I said to Lou in another thread, I think the generic alarm Yang could be defined in either Netmod or Teas, but the technology specific such as optical alarm Yang should be in the scope of CCAMP.



Thanks

Fatai

Hi authors, NETMOD chairs, CCAMP WG,

i went through the document and, despite believing it's a super well written and understandable document, I don't think it fits in CCAMP.
This is a more generic work with a scope broader than CCAMP. At a first thought I would say TEAS, but also TEAS is not the right place since it's not related to traffic engineering.
The day you plan to extend it with technological aspect, then CCAMP would be its natural home.

Fatai, do you agree with the analysis?

BR
Daniele

Hi Martin, Stefan,

thanks a lot for sharing the draft. I'll read it and let you know my personal opinion ASAP.

Working group, could you please do the same and share your thoughts?

Thanks
Daniele

Subject: [CCAMP] YANG Alarm Module in CCAMP?

Hi,

We have been working an a generic YANG module for alarm management for a while (draft-vallin-netmod-alarm-module).  The model is based on experience from several alarm management system over the years.  It has been presented in NETMOD (reflected in the draft name), but the NETMOD chairs felt that maybe CCAMP would be a better home for this draft.

So our question is if CCAMP would be interested in working on this draft?

The latest version is available as:
https://www.ietf.org/internet-drafts/draft-vallin-netmod-alarm-module-02.txt

 Abstract:
   This document defines a YANG module for alarm management.  It
   includes functions for alarm list management, alarm shelving and
   notifications to inform management systems.  There are also RPCs to
   manage the operator state of an alarm and administrative alarm
   procedures.  The module carefully maps to relevant alarm standards.
