Textual Conventions and General Group
Status of this Memo
This document specifies an Internet standards track protocol for the
Internet community, and requests discussion and suggestions for
improvements. Please refer to the current edition of the "Internet
Official Protocol Standards" (STD 1) for the standardization state
and status of this protocol. Distribution of this memo is unlimited.

Abstract
This document is one in the series of documents that provide MIB
definitions for for IP Version 6. Specifically, the IPv6 MIB textual
conventions as well as the IPv6 MIB General group is defined in this
document.
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the IPv6-based
internets.
This document specifies a MIB module in a manner that is both
compliant to the SNMPv2 SMI, and semantically identical to the peer
SNMPv1 definitions.

1. The SNMPv2 Network Management Framework
The SNMPv2 Network Management Framework presently consists of three
major components. They are:
o the SMI, described in RFC 1902 [1] - the mechanisms used
for describing and naming objects for the purpose of management.
o the MIB-II, described in RFC 1213/STD 17 [3] - the core
set of managed objects for the Internet suite of protocols.
o RFC 1157/STD 15 [4] and RFC 1905 [5] which define two versions
of the protocol used for network access to managed objects.
The Framework permits new objects to be defined for the purpose of
experimentation and evaluation.
1.1. Object Definitions
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined using the subset of Abstract Syntax Notation One (ASN.1)
defined in the SMI. In particular, each object type is named by an
OBJECT IDENTIFIER, an administratively assigned name. The object
type together with an object instance serves to uniquely identify a
specific instantiation of the object. For human convenience, we
often use a textual string, termed the descriptor, to refer to the
object type.
2. Overview
This document is the first in the series of documents that define
various MIB object groups for IPv6. These groups are the basic unit
of conformance: if the semantics of a group is applicable to an
implementation, then it must implement all objects in that group.
For example, an implementation must implement the TCP group if and
only if it implements the TCP over IPv6 protocol. At minimum,
implementations must implement the IPv6 General group defined in this
document as well as the ICMPv6 group [9].
Haskin & Onishi Standards Track [Page 2]RFC 2465 IPv6 MIB: General Group December 1998
This document defines the IPv6 MIB textual conventions as well as the
IPv6 General group which provides for the basic management of IPv6
entities and serve as the foundation for other IPv6 MIB definitions.
The IPv6 General group consists of 6 tables:
- ipv6IfTable
The IPv6 Interfaces table contains information on the
entity's IPv6 interfaces.
- ipv6IfStatsTable
This table contains information on the traffic statistics of
the entity's IPv6 interfaces.
- ipv6AddrPrefixTable
The IPv6 Address Prefix table contains information on
Address Prefixes that are associated with the entity's IPv6
interfaces.
- ipv6AddrTable
This table contains the addressing information relevant to
the entity's IPv6 interfaces.
- ipv6RouteTable
The IPv6 routing table contains an entry for each valid IPv6
unicast route that can be used for packet forwarding
determination.
- ipv6NetToMediaTable
The IPv6 address translation table contain the IPv6 Address
to `physical' address equivalencies.
3. IPv6 Address Representation
The IPv6 MIB defined in this memo uses an OCTET STRING of length 16
to represent 128-bit IPv6 address in network byte- order. This
approach allows to implement IPv6 MIB without requiring any changes
to the SNMPv2 SMI and compliant SNMP implementations.

DESCRIPTION
"A unique value, greater than zero for each
internetwork-layer interface in the managed

contiguously starting from 1. The value for each
internetwork-layer interface must remain constant
at least from one re-initialization of the entity's
network management system to the next

re-initialization."
SYNTAX Integer32 (1..2147483647)
Ipv6IfIndexOrZero ::= TEXTUAL-CONVENTION
DISPLAY-HINT "d"
STATUS current
DESCRIPTION
"This textual convention is an extension of the
Ipv6IfIndex convention. The latter defines
a greater than zero value used to identify an IPv6
interface in the managed system. This extension
permits the additional value of zero. The value
zero is object-specific and must therefore be
defined as part of the description of any object
which uses this syntax. Examples of the usage of
zero might include situations where interface was
unknown, or when none or all interfaces need to be
referenced."

}
MAX-ACCESS read-only
STATUS current
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)

Certain management information defined in this MIB may be considered
sensitive in some network environments.
Therefore, authentication of received SNMP requests and controlled
access to management information should be employed in such
environments.
