there is an option, something like '--nodown' that leaves all down 
ports enabled in the generated cfg...

I found that on slow hardware  (Sparcstation5 with openBSD 3.4), 
RRD + 14all.cgi was too slow to produce the images in a useful amount 
of time, so I stuck with stock MRTG.  when I moved to a Celeron 400 
with FreeBSD, I could move to RRD for everything and still get the 
web pages delivered in sensible time.  Now onto a C700 and it is 
quite happy doing a 48 port switch, plus a bunch of other devices 
including controlling the vent fans that help to cool the office.
