This is the "way it is designed".  I called in the same problem.  Please send 
mail to:
netview@tivoli.com
requesting a design change.  I think it is defective to have a router  which 
has suffered a power failure in marginal status instead of critical status just 
because one of the interfaces was administratively down.  The AD interface 
doesn't
count for status when all other interfaces are up, but it does when all 
interfaces are down.   I believe that it should be treated as an unmanaged 
interface in that regard.
