       Reassignment of Experimental MIBs to Standard MIBs

Status of this Memo

This RFC specifies an IAB standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "IAB Official Protocol Standards" for the standardization state and status of this protocol. Distribution of this memo is unlimited.

Statement

In the past, MIBs have been assigned arcs in the experimental MIB namespace early in their development and then were not assigned arcs in the standard MIB namespace until they reached Full Standard status. This practice required vendors to revise their implementations when a MIB went from Draft to Full Standard status, even though there was probably no substantive technical change in the definitions. This practice could also engender operational problems in the field at an undesirably late stage of the standardization process. It was also observed that this practice could discourage implementation until the Full Standard stage and that this, too, would be undesirable. So, a preferable practice is to assign arcs in the standard MIB namespace at the earliest phase of standardization and to preserve these assignments as the standard progresses.

This memo specifically updates:

  RFC 1229 - "Extensions to the Generic-Interface MIB"

  RFC 1230 - "IEEE 802.4 Token Bus MIB"

  RFC 1231 - "IEEE 802.5 Token Ring MIB"

  RFC 1232 - "Definitions of Managed Objects for the DS1 Interface
              Type"

  RFC 1233 - "Definitions of Managed Objects for the DS3 Interface
              Type"

with new codes. In the future, consult each MIB publication for new code assignments.
