IF types durring review of EPON-04

["David T. Perkins" <dperkins@dsperkins.com>]

HI,

I'm doing a second review of EPON-04 I-D, which is
http://www.ietf.org/internet-drafts/draft-ietf-hubmib-efm-epon-mib-04.txt

It is very complex and the previous review raised many questions.
The good news is that it is MUCH better, and it is finally to the
level that someone can make sense of it. However, given that
it is an interface MIB module, there are many additional
considerations that must be followed. I don't remember all of
them, and would need to refresh myself with these considerations
to do a complete job. Is there anyone that can do a scan
after I finish the first pass?

One question that I have so far is what interface type
to use for the virtual links. The document uses the
same value as the physical (which is gigabitEthernet(117)),
but it seems to me that the propVirtual(53) is more
appropriate.
 
In trying to determine the value for ifType, I looked at
http://www.iana.org/assignments/ianaiftype-mib
In it I see that there are 234 types defined.
This seems like an extremely large number. Also,
there is not a reference for each assigned value.
Thus, I could not figure out from looking at
these values what values the should be used
in the EPON MIB module. This seems like a generic
problem that anyone implementing object ifType
would encounter. And a delemma for anyone creating
a new interface MIB module. 

Are there any suggestions that would help me
now with the EPON MIB module, and for making it
easier for future interface MIB module developers?
