RFC 8096
The IPv6-Specific MIB Modules Are Obsolete
RFC 8096: The IPv6-Specific MIB Modules Are Obsolete 🦋
Okay bestie, this is RFC 8096, and its title is The IPv6-Specific MIB Modules Are Obsolete 💅 It was written by B. Fenner from Arista Networks, Inc., and it's dated April 2017. It's Informational (ISSN 2070-1721), and it obsoletes RFCs 2452, 2454, 2465, and 2466 ✨
Abstract 💖
Back in 2005-2006, the IPv6 MIB update group put out new versions of the IP-MIB, UDP-MIB, TCP-MIB, and IP-FORWARD-MIB modules. These use the InetAddressType/InetAddress construct so IPv4 and IPv6 can share the same table, and it's giving iconic 🌈 This document includes versions of the obsoleted IPV6-MIB, IPV6-TC, IPV6-ICMP-MIB, IPV6-TCP-MIB, and IPV6-UDP-MIB modules, so MIB module repositories can get updated 🧚 It obsoletes RFCs 2452, 2454, 2465, and 2466 (meaning the RFCs that contain these MIBs) and reclassifies them as Historic 🎀
Status of This Memo 🌸
This document isn't an Internet Standards Track specification. It's published for informational purposes only ✨
It's a product of the Internet Engineering Task Force (IETF), and it represents the consensus of the IETF community. It went through public review and got approved for publication by the Internet Engineering Steering Group (IESG). Not every document the IESG approves is a candidate for any level of Internet Standard, so check out Section 2 of RFC 7841 for the details 🙈

Okay so, back in 2005-2006, the IPv6 MIB update group published updated versions of the IP-MIB [RFC4293], UDP-MIB [RFC4113], TCP-MIB [RFC4022], and IP-FORWARD-MIB [RFC4292] modules. They use the InetAddressType/InetAddress construct to handle IPv4 and IPv6 in the same table 💅 The RFC Editor marked these documents as obsoleting the matching IPV6-MIBs. But the extracted content of those MIBs never changed in MIB repositories, and the original RFCs never moved off Proposed Standard, which is normal IETF policy 🙄
Here's the timeline for these MIB modules (and honestly, the added IPv6 support in the later revision of the original modules is the part people always overlook 👀):
IPv6-MIB--------X
\
IP-MIB-------------------IP-MIB--->This creates an unclear situation whenever you just look at MIB repositories, so we're republishing these MIB modules with the Structure of Management Information (SMI) status changed to obsolete. This is an unusual move, and it's not the intended path for every obsolete MIB module. The special history of these modules is what led to this special step ✨

an IPv6 interface attached to an 802.x link, this
object normally contains a MAC address. Note that
in some cases this address may differ from the
address of the interface's protocol sub-layer. The
interface's media-specific MIB must define the bit

this object. For interfaces which do not have such
an address (e.g., a serial line), this object should
contain an octet string of zero length.
This object is obsoleted by IF-MIB::ifPhysAddress."

}
MAX-ACCESS read-write
STATUS obsolete
DESCRIPTION
"The desired state of the interface. When a managed
system initializes, all IPv6 interfaces start with
ipv6IfAdminStatus in the down(2) state. As a result
of either explicit management action or per
configuration information retained by the managed
system, ipv6IfAdminStatus is then changed to
the up(1) state (or remains in the down(2) state).
This object is obsolete. IPv6 does not have a
separate admin status; the admin status of the
interface is represented by IF-MIB::ifAdminStatus."
::= { ipv6IfEntry 9 }ooh the ipv6IfIdentifierLength one is a bit of a diva 🙈 it says interface identifiers that aren't an even number of octets just aren't supported, so keep that in mind when you're reading the MIB 💜
that's the whole vibe for this bit 🦋 more of the MIB is coming, so stay tuned, bestie ✨

notPresent(5) -- missing
}
MAX-ACCESS read-only
STATUS obsolete
DESCRIPTION
"The current operational state of the interface.
The noIfIdentifier(3) state indicates that no valid
Interface Identifier is assigned to the interface.
This state usually indicates that the link-local
interface address failed Duplicate Address Detection.
If ipv6IfAdminStatus is down(2) then ipv6IfOperStatus
should be down(2). If ipv6IfAdminStatus is changed
to up(1) then ipv6IfOperStatus should change to up(1)
if the interface is ready to transmit and receive
network traffic; it should remain in the down(2) or
noIfIdentifier(3) state if and only if there is a
fault that prevents it from going to the up(1) state;
it should remain in the notPresent(5) state if
the interface has missing (typically, lower layer)
components.
This object is obsolete. IPv6 does not have a
separate operational status; the operational status of the
interface is represented by IF-MIB::ifOperStatus."
::= { ipv6IfEntry 10 }

::= { ipv6IfStatsEntry 16 }okay bestie, the status stuff is giving "this is obsolete, go look at IF-MIB" 💅 ipv6IfOperStatus says IPv6 doesn't have its own operational status anymore, so the real answer lives in IF-MIB::ifOperStatus 🦋
and the stats table is a whole vibe too 🧚 every counter says "obsoleted by IP-MIB::..." so it's basically a pointer to the newer table 🎀
the key drama is that ipv6IfStatsInTooBigErrors wasn't copied over to IP-MIB at all, because systems didn't keep the incoming interface of a packet that failed fragmentation 😭🫶
Okay bestie, the IPv6 stats counters are next, and they're giving retired-but-still-iconic energy 🥹✨ Every one of these is marked obsolete, and IP-MIB has taken over their jobs 💅

END5. Historic IPV6-UDP-MIB ✨
okay so this section is the IPV6-UDP-MIB, which is the MIB module for UDP over IPv6 🦋 It's historic now, so it's giving retired-but-still-iconic energy. The module's own DESCRIPTION says it's obsolete and that you should use the UDP-MIB instead. It was replaced by the revised UDP-MIB (RFC 4113), and the first version came out as RFC 2454 💅
The module is registered under experimental 87, and its contact is Mike Daniele at Compaq Computer Corporation in Nashua, NH 💜 It imports a few things from SNMPv2-CONF, SNMPv2-SMI and IPV6-TC, like Ipv6Address and Ipv6IfIndexOrZero 🧚
Here's the whole module, copied exactly:

END🫶 so the big picture: the table ipv6UdpTable only holds the UDP listeners on IPv6 endpoints, and the IPv4 ones stay in udpTable. Every object in here is marked obsolete, and each one points you over to a UDP-MIB object (like UDP-MIB::udpEndpointTable) that replaces it 🌸
the ipv6UdpIfIndex description is the one to read carefully 👀 if no local interface can be figured out, the value is 0, and for a non-0 value it's the same interface as ipv6IfIndex. it also has to stay constant for the whole life of the UDP endpoint 🔥
The compliance statement ipv6UdpCompliance and the group ipv6UdpGroup are both obsolete too, so UDP-MIB::udpMIBCompliance2 and those several UDP-MIB groups are where it's at now 💖

okay so this section is giving housekeeping 🧹 this doc reclassifies [RFC2452], [RFC2454], [RFC2465], and [RFC2466] to Historic. so they're officially retired, no cap 🪦✨
8. Security Considerations 🔒
this part is super important, so listen up 👑 this document only has obsolete objects, and [RFC2578] says "should not be implemented and/or can be removed if previously implemented". since the stuff in here shouldn't be implemented, it has no security implications 🫶
If there were any security implications based on these objects in an implementation, removing these objects as [RFC2578] suggests would improve the security of that implementation. So if you're running something built on these objects, go clean them up 🔐💜
9. IANA Considerations 💅
IANA has updated the SMI Numbers registry at http://www.iana.org/assignments/smi-numbers/ as described below. the registry got a glow-up 🌈
IANA has updated the "SMI Network Management MGMT Codes Internet-standard MIB" section as follows:
- Removed RFC 1213 as a reference for mib-2.5 ("icmp").
- Updated the reference for mib-2.6 ("tcp") to point to RFC 4022.
- Removed RFC 1213 as a reference for mib-2.7 ("udp").
- Removed RFC 2012 as a reference for mib-2.49 ("tcpMIB").
- Added the "(Historic)" annotation for the entries for mib-2.55 ("ipv6MIB") and mib-2.56 ("ipv6IcmpMIB") and updated the reference of each to point to this document.
IANA has updated the "SMI Experimental Codes" section as follows:
- Added the "(Historic)" annotation for experimental.74 ("IPv6 MIB").
- Changed the "(Historical)" annotation for experimental.87 ("ipv6UdpMIB") to "(Historic)".
- Updated the reference for experimental.86 ("ipv6TcpMIB") and experimental.87 ("ipv6UdpMIB") to point to this document.
