	There is no "part of the OID".  OIDs (object identifiers) are atomic.

	That is all that a MIB does.  It is an opaque interface description.

	The information may be in a different place on every different system that supports the MIB.  For each, a subagent must be provided which responds to the get, set, etc. queries and returns or changes the data as needed.
