RFC 1239

Reassignment of Experimental MIBs to Standard MIBs ✨

Okay bestie, this is RFC 1239 🎀 It came from the Network Working Group, written by J. Reynolds at ISI in June 1991. It's an IAB standards track protocol, and it updates RFCs 1229, 1230, 1231, 1232, and 1233 💖

Status of this Memo 🌸

So this RFC specifies an IAB standards track protocol for the Internet community, and it's literally asking for discussion and suggestions for improvements 🫶 For the standardization state and status of this protocol, check the current edition of the "IAB Official Protocol Standards." Distribution of this memo is unlimited 🌈

Statement 🍵

Here's the tea. In the past, MIBs got arcs in the experimental MIB namespace super early in their development, but they didn't get arcs in the standard MIB namespace until they hit Full Standard status. That was lowkey annoying, because vendors had to revise their implementations when a MIB went from Draft to Full Standard, even though there was probably no substantive technical change in the definitions 😭 It could also cause operational problems out in the field at a really late stage of the standardization process 💀 And it was noticed that this practice could discourage implementation until the Full Standard stage, which is also not it.

So the better move 👑 is to assign arcs in the standard MIB namespace at the earliest phase of standardization, and then keep those 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"

These get new codes. In the future, consult each MIB publication for new code assignments 🧚

Security issues are not discussed in this memo. 💀 Read that twice, bestie, because this one is not the place to look for them.
