Reassignment of EXPerimental MIBs to Standard MIBs
Status of this Memo
This RFCspecifies 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:
RFC1229 - "Extensions to the Generic-Interface MIB"
RFC1230 - "IEEE 802.4 Token Bus MIB"
RFC1231 - "IEEE 802.5 Token Ring MIB"
RFC1232 - "Definitions of Managed Objects for the DS1 Interface
Type"
RFC1233 - "Definitions of Managed Objects for the DS3 Interface
Type"
with new codes. In the future, consult each MIB publication for new
code assignments.
