We had the same problems. We have lots of 4000's and 1800's and a couple of
50/75's and 2000's.
I have a script I could send to anyone if they like.
Real hack, but it works.
Just does an snmpwalk of the max at the time (a little intensive I know...) and
'greps' for the IF address anda few other things and that gives you the
interface number.
For REAL dynamic boxes such as Linux / BSD terminal servers and things like
that, we nice lenthy for x in .. loop does the job
