        This is a tough one to explain, and I don't have time to provide an 
example, but I think you're misunderstanding the point of the mask.  It allows 
you to skip one or more identifiers in an OID specification.  The typical use 
case is for tables - access can be allowed to some of the conceptual columns by 
setting the mask bit to 0 for the index.  This does not, of course, work for 
string valued indices, which may explain why some MIBs may be indexed by an 
arbitrary integer when there is one or more string values that uniquely 
identify the conceptual row.


        HTH,
