RFC 2514
Definitions of Textual Conventions and OBJECT-IDENTITIES for ATM Management
RFC 2514: Definitions of Textual Conventions and OBJECT-IDENTITIES for ATM Management ✨
Okay bestie, let's get the vibes straight first 💖 This RFC is from the Network Working Group and it's a Standards Track doc, dated February 1999. It was written by Michael "Mike" Noto from 3Com, Ethan Mickey Spiegel from Cisco Systems, and Kaj Tesink from Bellcore, and all three of them are the editors 🎀 The doc doesn't say it obsoletes or updates anything, so there's no drama there 🫶
The big topic is ATM management. It's all about defining the Textual Conventions and OBJECT-IDENTITIES that ATM MIB modules can use 🦋
Status of This Memo 📜
Okay so this part is the official "what kind of doc is this" bit. It's an Internet standards track protocol for the Internet community, and the authors are openly asking for discussion and suggestions for improvements 💅 If you want the current standardization state of this protocol, you're supposed to check the current edition of the "Internet Official Protocol Standards" (STD 1). And the good news is that distribution of this memo is unlimited 🌈

So the whole point is this: the memo describes Textual Conventions and OBJECT-IDENTITIES used for managing ATM-based interfaces, devices, networks and services 🧚
1. Introduction ✨
Okay so this section is the setup, and it's giving "why do we even need this" energy 🙈
When you're designing a MIB module, it's really handy to make new types that look like the ones already defined in the SMI. Compared to an SMI type, each of these new types has a different name, a similar syntax, but a more precise semantics 💅 These new types are called textual conventions, and they exist so that humans reading the MIB module can understand things more easily. That's done through Textual Conventions as defined in RFC1903 [1]. And the purpose of this document is to define the set of textual conventions that ATM MIB modules can use 🦋
Also, when you're designing MIB modules, it's often useful to register extra properties with object identifier assignments, so other MIB modules can use them too 👑 That's done through the OBJECT-IDENTITY macro defined in RFC1902 [2], and this document defines the OBJECT-IDENTITIES that ATM MIB modules can use 🫶
Now the tea ☕ The OBJECT IDENTITIES that were previously defined in RFC1695 got moved over to this specification for organizational reasons, so they no longer appear in the revision of RFC1695 [3]. The good part is that the original OBJECT IDENTIFIERs were preserved 🎀
And if you want an intro to the concepts of ATM connections, go check out [3] 🌈
2. Definitions 📖

DESCRIPTION

and OBJECT-IDENTITY Objects to be used by
ATM systems."
::= { mib-2 37 3 } -- atmMIB 3 (see [3])
-- The Textual Conventions defined below are organized
-- alphabetically
AtmAddr ::= TEXTUAL-CONVENTION
DISPLAY-HINT "1x"
STATUS current
DESCRIPTION
"An ATM address. The semantics are implied by
the length. The address types are: - no
address (0 octets) - E.164 (8 octets) - NSAP
(20 octets) In addition, when subaddresses
are used the AtmAddr may represent the
concatenation of address and subaddress. The
associated address types are: - E.164, E.164
(16 octets) - E.164, NSAP (28 octets) - NSAP,
NSAP (40 octets) Address lengths other than
defined in this definition imply address
types defined elsewhere. Note: The E.164
address is encoded in BCD format."
SYNTAX OCTET STRING (SIZE(0..40))
AtmConnCastType ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"The type of topology of a connection (point-
to-point, point-to-multipoint). In the case
of point-to-multipoint, the orientation of
this VPL or VCL in the connection.
On a host:
- p2mpRoot indicates that the host
is the root of the p2mp connection.
- p2mpLeaf indicates that the host
is a leaf of the p2mp connection.
On a switch interface:
- p2mpRoot indicates that cells received
by the switching fabric from the interface
are from the root of the p2mp connection.
- p2mpLeaf indicates that cells transmitted
to the interface from the switching fabric
are to the leaf of the p2mp connection."

AtmConnKind ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"The type of call control used for an ATM
connection at a particular interface. The use
is as follows:
pvc(1)
Virtual link of a PVC. Should not be
used for an PVC/SVC (i.e., Soft PVC)
crossconnect.
svcIncoming(2)
Virtual link established after a
received signaling request to setup
an SVC.
svcOutgoing(3)
Virtual link established after a
transmitted or forwarded signaling
request to setup an SVC.
spvcInitiator(4)
Virtual link at the PVC side of an
SVC/PVC crossconnect, where the
switch is the initiator of the Soft PVC
setup.
spvcTarget(5)
Virtual link at the PVC side of an
SVC/PVC crossconnect, where the
switch is the target of the Soft PVC
setup.
For PVCs, a pvc virtual link is always cross-
connected to a pvc virtual link.
For SVCs, an svcIncoming virtual link is always cross-
connected to an svcOutgoing virtual link.
For Soft PVCs, an spvcInitiator is either cross-connected to
an svcOutgoing or an spvcTarget, and an spvcTarget is either
cross-connected to an svcIncoming or an spvcInitiator."

AtmIlmiNetworkPrefix ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"A network prefix used for ILMI address
registration. In the case of ATM endsystem
addresses (AESAs), the network prefix is the first
13 octets of the address which includes the AFI,
IDI, and HO-DSP fields. In the case of native
E.164 addresses, the network prefix is the entire
E.164 address encoded in 8 octets, as if it were
an E.164 IDP in an ATM endsystem address
structure."

okay so this section is basically the IETF saying "we're not picking a side on who owns what 🫠" 💅 They take no position on whether any rights might be claimed over the technology in this doc, or whether licenses are available for it, and they don't claim they've gone looking for any such rights either 🙈 If you want the details on how the IETF handles rights for standards-track stuff, that lives in BCP-11 🎀 Copies of rights claims, license assurances, or results of attempts to get a general license can be requested from the IETF Secretariat 💜
And if anyone out there knows about copyrights, patents, patent applications, or other proprietary rights that might cover technology needed to practice this standard, the IETF wants to hear about it 🦋 Send that info to the IETF Executive Director, bestie 🫶

okay, the sharing rules are actually pretty generous 💖 You can copy and share this document and translations of it, and you can make derivative works that comment on it, explain it, or help people implement it, and publish and distribute those in whole or in part with no restriction of any kind 🎀 The one catch is that the copyright notice and this paragraph have to be included on all copies and derivative works 💅
BUT you can't modify this document itself in any way, like removing the copyright notice or references to the Internet Society or other Internet organizations 🙅♀️ The exceptions are when you need it for developing Internet standards (then the Internet Standards process copyright procedures must be followed) or when you're translating it into languages other than English 🌸
The limited permissions above are perpetual and won't be revoked by the Internet Society or its successors or assigns ⭐
And the usual legal bit, in all caps because it's serious: this document and the information in it is provided on an "AS IS" basis, and THE INTERNET SOCIETY AND THE INTERNET ENGINEERING TASK FORCE DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY WARRANTY THAT THE USE OF THE INFORMATION HEREIN WILL NOT INFRINGE ANY RIGHTS OR ANY IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE 💀
