	Managed objects are accessed via a virtual information store, termed
	the Management Information Base or MIB. Objects in the MIB are
	defined using the mechanisms defined in the SMI.

	This memo specifies a MIB module that is compliant to the SMIv2. A
	MIB conforming to the SMIv1 can be produced through the appropriate
	translations. The resulting translated MIB must be semantically
	equivalent, except where objects or events are omitted because no

	information in SMIv2 will be converted into textual descriptions in
	SMIv1 during the translation process. However, this loss of machine-
	readable information is not considered to change the semantics of the
