I don't have an MSFC 3, but I do have a 6506 running CatOS with an MSFC 2. I have both devices added to DCR, and when I bring up the map, I see them both as distinct icons. That is, the 6506 shows up as a square switch icon, and the MSFC shows up as a circular router icon. In the right-hand tree view, I see "Cat6000-MSFC". If I check the box next to that, the MSFC router icon stays green on the map. I see no reason why this would not work for an MSFC 3 provided the device was properly data collected by Campus.
