Abstract
This document introduces a Management Information Base (MIB) module
that defines textual conventions to represent commonly used
transport-layer addressing information. The definitions are
compatible with the concept of TAddress/TDomain pairs introduced by
the Structure of Management Information version 2 (SMIv2) and support
the Internet transport protocols over IPv4 and IPv6.

RFC 3419 Textual Conventions for Transport Addresses December 2002
1. Introduction
Several MIB modules need to represent transport-layer addresses in a
generic way. Typical examples are MIBs for application protocols
that can operate over several different transports or application
management MIBs that need to model generic communication endpoints.
The SMIv2 in STD 58, RFC 2579 [RFC2579] defines the textual
conventions TDomain and TAddress to represent generic transport layer
endpoints. A generic TAddress value is interpreted in a given
transport domain which is identified by a TDomain value. The TDomain
is an object identifier which allows MIB authors to extend the set of
supported transport domains by providing suitable definitions in
standardized or enterprise specific MIB modules.
An initial set of TDomain values and concrete TAddress formats has
been standardized in STD 62, RFC 3417 [RFC3417]. These definitions
are however mixed up with SNMP semantics. Furthermore, definitions
for Internet transport protocols over IPv4 and IPv6 are missing.
The purpose of this memo is to introduce a set of well-known textual
conventions to represent commonly used transport-layer addressing
information which is compatible with the original TDomain and
TAddress approach and which includes definitions for additional
Internet transport protocols over IPv4 and IPv6. This memo also
introduces a new textual convention which enumerates the well-known
transport domains since such an enumeration provides in many cases
sufficient flexibility and is more efficient compared to object
identifiers.
The key words "MUST", "MUST NOT", "SHOULD", "SHOULD NOT" and "MAY" in
this document are to be interpreted as described in BCP 14, RFC 2119
[RFC2119].
2. The Internet-Standard Management Framework
For a detailed overview of the documents that describe the current
Internet-Standard Management Framework, please refer to section 7 of
RFC 3410 [RFC3410].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. MIB objects are generally
accessed through the Simple Network Management Protocol (SNMP).
Objects in the MIB are defined using the mechanisms defined in the
Structure of Management Information (SMI). This memo specifies a MIB
module that is compliant to the SMIv2, which is described in STD 58,
RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
[RFC2580].
Daniele & Schoenwaelder Standards Track [Page 2]
RFC 3419 Textual Conventions for Transport Addresses December 2002
3. Overview
This MIB module contains definitions for commonly used transport
layer addressing information. In particular, it provides the
following definitions:
1. Textual conventions for generic transport addresses
(TransportAddress) and generic transport domains
(TransportDomain).
2. Object identifier registrations for well-known transport domains.
3. An enumeration of the well-known transport domains, called a
transport address type (TransportAddressType).
4. A set of textual conventions for the address formats used by
well-known transport domains. The DISPLAY-HINTs are aligned with
the formats used in URIs [RFC2396], [RFC3291].
The textual conventions for well-known transport domains support
scoped Internet addresses. The scope of an Internet address is a
topological span within which the address may be used as a unique
identifier for an interface or set of interfaces. A scope zone, or
simply a zone, is a concrete connected region of topology of a given
scope. Note that a zone is a particular instance of a topological
region, whereas a scope is the size of a topological region [SCOPED].
Since Internet addresses on devices that connect multiple zones are
not necessarily unique, an additional zone index is needed on these
devices to select an interface. The textual conventions
TransportAddressIPv4z and TransportAddressIPv6z are provided to
support Internet transport addresses that include a zone index. In
order to support arbitrary combinations of scoped Internet transport
addresses, MIB authors SHOULD use a separate TransportDomain or
TransportAddressType objects for each TransportAddress object.
There are two different ways how new transport domains and textual
conventions for the address formats used by those new transport
domains can be defined.
1. The MIB module contained in this memo can be updated and new
constants for the TransportDomain and the TransportAddressType
enumeration can be assigned.
2. Other MIB modules may define additional transport domains and
associated textual conventions. Such an extension can not update
the TransportAddressType enumeration.
Daniele & Schoenwaelder Standards Track [Page 3]
RFC 3419 Textual Conventions for Transport Addresses December 2002
It is therefore a MIB designers choice whether he uses (a) a more
compact TransportAddressType object with limited extensibility or (b)
a more verbose TransportDomain object which allows arbitrary
extensions in other MIB modules.
The MIB module contained in this memo does NOT define the transport
mappings of any particular protocol. Rather, it defines a set of
common identifiers and textual conventions that are intended to be
used within various transport mappings documents.
3.1 Relationship to Other MIBs
This section discusses how the definitions provided by the MIB module
contained in this memo relate to definitions in other MIB modules.
3.1.1 SNMPv2-TC (TAddress, TDomain)
The SNMPv2-TC MIB module [RFC2579] defines the textual conventions
TAddress and TDomain to represent generic transport addresses.
A TAddress is an octet string with a size between 1 and 255 octets.
Experience has shown that there is sometimes a need to represent
unknown transport addresses. The MIB module contained in this memo
therefore introduces a new textual convention TransportAddress which
is an octet string with a size between 0 and 255 octets and otherwise
identical semantics. In other words, the sub-type TransportAddress
(SIZE (1..255)) is identical with the TAddress defined in the
SNMPv2-TC MIB module [RFC2579].
This MIB module also introduces a new textual convention
TransportDomain which is compatible with the TDomain definition so
that a complete set of definitions is contained in a single MIB
module. New MIB modules SHOULD use the generic TransportDomain,
TransportAddressType and TransportAddress definitions defined in this
memo. Existing MIB modules may be updated to use the definitions
provided in this memo by replacing TDomain with TransportDomain and
TAddress with TransportAddress (SIZE (1..255)).
3.1.2 SNMPv2-TM
The transport domain values defined in the SNMPv2-TM MIB module
[RFC3417] all contain "snmp" as the prefix in their name and are
registered under `snmpDomains' (from RFC 2578 [RFC2578]). They were
originally intended to describe SNMP transport domains only - but
they were later also used for non-SNMP transport endpoints. These
definitions are also incomplete since new transport address domains
are needed to support (at least) SNMP over UDP over IPv6.
Daniele & Schoenwaelder Standards Track [Page 4]
RFC 3419 Textual Conventions for Transport Addresses December 2002
The transport domain values defined in this memo are independent of
the protocol running over the transport-layer and SHOULD be used for
all transport endpoints not carrying SNMP traffic. Programs that
interpret transport domain values should in addition accept the
transport domain values defined in the SNMPv2-TM MIB module in order
to provide interoperability with existing implementations that use
the SNMP specific transport domain values.
Transport endpoints which carry SNMP traffic SHOULD continue to use
the definitions from the SNMPv2-TM MIB module where applicable. They
SHOULD use the transport domain values defined in this memo for SNMP
transports not defined in the SNMPv2-TM MIB module, such as SNMP over
UDP over IPv6. Programs that interpret transport domain values
should in addition accept all the transport domain values defined in
this memo in order to provide interoperability in cases where it is
not possible or desirable to distinguish the protocols running over a
transport endpoint.
3.1.3 INET-ADDRESS-MIB (InetAddressType, InetAddress)
The INET-ADDRESS-MIB MIB module [RFC3291] defines the textual
conventions InetAddressType and InetAddress to represent Internet
network layer endpoints. Some MIB modules use these textual
conventions in conjunction with the InetPortNumber textual convention
to represent Internet transport-layer endpoints. This approach is
fine as long as a MIB models protocols or applications that are
specific to the Internet suite of transport protocols. For protocols
or applications that can potentially use other transport protocols,
the use of the definitions contained in this memo is more
appropriate.

RFC 3419 Textual Conventions for Transport Addresses December 2002
specify the TransportAddressType or TransportDomain object
which provides the context. Furthermore, MIB authors SHOULD
define a separate TransportAddressType or TransportDomain
object for each TransportAddress object. It is suggested that
the TransportAddressType or TransportDomain is logically
registered before the object(s) which use the
TransportAddress textual convention if they appear in the
same logical row.
The value of a TransportAddress object must always be
consistent with the value of the associated
TransportAddressType or TransportDomain object. Attempts
to set a TransportAddress object to a value which is
inconsistent with the associated TransportAddressType or
TransportDomain must fail with an inconsistentValue error.

6. Security Considerations
The MIB module contained in this memo does not define any management
objects. Instead, it defines a set of textual conventions which may
be used by other MIB modules to define management objects.
Meaningful security considerations can only be written for MIB
modules that define concrete management objects. This document has
therefore no impact on the security of the Internet.
