Thats much like alot of the Cisco routers that have switch ports on them.
Its confusing, because they look like real layer-3 interfaces, but the
devices are really hybrids, broken out so you can manage the layer-2 ports
as well as the layer-3 single port that they'll go through both.
All the newer 8xx boxes are like this (even some of the older ones get
this fashion with the later IOS revs that they didn't have before), as
well as the HWIC-4ESW/9ESW cards, etc.
Just think of it as a switch grafted onto a router port somewhere
else, and you control both the switch section and the router section
all in one config. Don't think of it as seperate ports that you
control on the IP side, its a switch grafted onto a router, much like
you'd have if you had physically two devices, in this case, the uplink
cable is internal.
