	This is a bit of a design problem as stated.  The (sub)agent is responsible for managing its OID range, and therefore it is not possible to have a subagent completely unaware of the OIDs.  This does not, however, mean that the subagent needs to be aware of the data underlying the MIB.

	A common paradigm is to have the subagent register for the range of values (table, MIB, whatever) that it will manage, and have the OP (other process) manage the data within the range.  The agent does OID assembly/disassembly (i.e. breaking OIDs into range part and specific part), possibly reformat the specific part to make it more understandable to the OP (thus only the subagent need be MIB aware).  The OP returns the values for the requested data, then the subagent formats and assembles the response.


	HTH,

Mike
