Hi,
	We approach it a little differently and collect all the data via
netflow, or in this case argus.  I sample the parent interface and save
all the flow data which argus is smart enough to parse out at the vlan
level.  You can then run all sorts of fine grained reports this way.  We
use it on a system with about 900 ng interfaces.
