HI Peder Chr. Norgaard,
I believe we pretty are much in agreement that what was done
in many of the access routines and event reporing routines
in NET-SNMP can and should be updated.
The note was to help other readers with understanding that
the change was not to add any new capabilities to NET-SNMP,
but to change the mechanism used to report link up and
link down events.
Note, on terminology, I really wish there was a good
reference, since I believe that in telco speak there
are two types of alarms - one for "standing conditions"
and one for (I forgot the actual term) "instance events"
(for example, a failed login attempt). If you have
a good reference, please send me a citation.
Well, yes, I do have a reference for terminology - but you probably know
about that yourself. It is X.733 and X.734 (also known as ISO/IEC 10164-4
and 10164-5). This is where the concepts of events and alarms are
defined; the short story is that an "alarm" in this context is a
specialized "event" which has to be reset by another special "event".
A purist will of course point out that the ifUp/ifDown pair is not a true
alarm in this context, and I will have to agree; I used the term only
because the pair shares the high-level functional goal with a real X.733
alarm: to mirror a binary status of a node to a management station.
