You really don't want to combine the data from all interfaces into one RRD 
file.  What happens when you decide to add another interface?    Either 
you're faced with the ugliness of unloading the existing data and patching 
it to add room for the new interface, or you have to deal with the ugliness 
of having some interfaces in the main rrd and some elsewhere.  Given that 
rrdtool easily deals with making graphs combining the data from multiple 
rrds, I can see no reason to put all the interfaces in one rrd; multiple 
rrds are just easier all around.

If you need it quickly and can't do it yourself, your best bet is to hire 
someone to do it for you.
