- Back in the Mid '80s a bunch of us at Wollongong (at the time) set about
- collecting the list of variables to be part of the 1st general
- purpose SNMP MIB. One of the requirements for the items related to
- the interface was that they be generic to all interfaces as much as
- possible. Collisions are meaningfull on ethernet, but not on many
- other media. In the years since then I've implmented many agents, and
- about 50% of the if table devices turn out to be ethernet. I guess you
- could debate if one should implement a variable that only applies
- about half the time, but keep in mind that we didn't know how long
- ethernet would be popular as a media (we were also using token ring
- and fiber). Even with hindsight, I think it was the right decision.
-
- You should also note that MIB-II allows for extensions to the if
- Table via the "ifSpecific" object. There is an ethernet MIB which maps
- into that which, I assume, includes collision counts.
