Dennis or Siva are probably better suited to answer this, but AFAIK if
a platform has that many IDBs it's not to handle vlans or channels,
but dial-related ppp-terminating types of stuff, which about I do not
know much.

Also, standard cya disclaimer - just because the box can *take* 10,000
IDBs or 2048 or 8192 doesn't necessarily mean that it will do whatever
you want on every single subinterface.  But you knew that already,
right? :)
