Review completed: 2019-03-18


I have been assigned to review this draft on behalf of the OPS DIR.  Overall, I found the draft ready with some nits.  I found relatively easy to read and well-thought-through.  Broadly speaking, I found the term "Alarm Shelving" to be confusing.  You do define this, but it is not something that many operators are familiar with.  I had originally thought alarm suppression was better, but after I read more, I see what you're trying to do with this.

Additionally, some of the features like alarm-history and alarm-shelving have a potential operational impact with respect to local server resources, and perhaps that's worth calling out.

The leaf "has-clear" seems like it would read better as "has-cleared" from an English standpoint.  Thoughts?

Finally, I can see where it might be desirable to suppress alarm notifications without shelving them per se.  That is, the alarm remains in the list, but notifications are not sent.  That doesn't seem possible, and I'm wondering if it's worth considering.

My per-section nits (typos) are found below.

Section 3.2

Section 3.5.1

In the example, ((GigabitEthernet0/25, link-
   alarm,""), false, T, major, "Interface GigabitEthernet0/25 down"), maybe replace 'T' with a sample timestamp.  It took me a few seconds to grok that as I was associating it with a boolean.
