My understanding of a full duplex ethernet network was that a 100megabit network would shift 100Mb (=12.5MB) in each direction at the same time. So no, you do not want to add them together. If you have a 10Mb half-duplex system it can do 10Mb in OR out, but packet collisions result from trying to do both at the same time. So then adding the figures together would have some sort of meaning, but I would not bother. Asynchrounous systems (eg Broadband in the UK) will shift 500kb one way and 128Kb the other. So you certainly do not want those added together! If you want a third line on the graph representing total In + total Out, you will be pushed under just MRTG, but upgrade to use RRD to store your data and use a front end such as Routers2.cgi to view your data. Front ends often have a totalling feature built in.
