I just have tried to read again all the mail which has been written on this
subject (Taking into account the kilobytes we will not be accused by Jeff 
at the next meeting for being an UnWorking Group).
Providing such information externally may surely give extra value. It was 
suggested that what we really get is a 'connection table' which extends
to all types of 'ports' and Keith proposed a scheme (indexType, indexValue)
which I think might work. This type of 'connectivity table' opens the path
for interesting applications in which the mapping between objects, through
devices to segments (networks) can be described.
And yes, I think this does belong to the Chassis MIB, if we agree that we
need it, that we can implement it some way or another and that what we have 
here is a unitary approach, which can cover the different possible options.
I would like to see Dave's initial proposal with Keith's scheme merged and
have them discussed as soon as possible.
