This memo provides the initial version of the Management Information
Base (MIB) for use with network management protocols in TCP/IP-based
internets in the short-term. In particular, together with its
companion memos which describe the structure of management
information along with the initial network management protocol, these
documents provide a simple, workable architecture and system for
managing TCP/IP-based internets and in particular the Internet.

RFC 1066 MIB August 1988
This memo specifies a draft standard for the Internet community.
TCP/IP implementations in the Internet which are network manageable
are expected to adopt and implement this specification.
Distribution of this memo is unlimited.
This MIB specification is the first edition of an evolving document
defining variables needed for monitoring and control of various
components of the Internet. Not all groups of defined variables are
mandatory for all Internet components.
For example, the EGP group is mandatory for gateways using EGP but
not for hosts which should not be running EGP. Similarly, the TCP
group is mandatory for hosts running TCP but not for gateways which
aren't running it. What IS mandatory, however, is that all variables
of a group be supported if any element of the group is supported.
It is expected that additional MIB groups and variables will be
defined over time to accommodate the monitoring and control needs of
new or changing components of the Internet. The MIB working group
will continue to refine this specification and projects a revision
incorporating new requirements in early 1989.
As reported in RFC 1052, IAB Recommendations for the Development of
Internet Network Management Standards [1], the Internet Activities
Board has directed the Internet Engineering Task Force (IETF) to
create two new working groups in the area of network management. One
group is charged with the further specification and definition of
elements to be included in the Management Information Base. The
other is charged with defining the modifications to the Simple
Network Management Protocol (SNMP) to accommodate the short-term
needs of the network vendor and operator communities. The long-term
needs of the Internet community are to be met using the ISO CMIS/CMIP
[2,3] framework as a basis. An existing IETF working group, the
"NETMAN" group, is already engaged in defining the use of CMIS/CMIP
in a TCP/IP network, and will continue with responsibility for
addressing the longer-term requirements.
The output of the MIB working group is to be provided to both the
SNMP working group and the NETMAN group, so as to ensure
compatibility of monitored items for both network management
frameworks.
The MIB working group has produced this memo and a companion. The
McCloghrie & Rose [Page 2]
RFC 1066 MIB August 1988
companion memo [4] defines a Structure for Management Information
(SMI) for use by the managed objects contained in the MIB. This memo
defines the list of managed objects.
The IAB also urged the working groups to be "extremely sensitive to
the need to keep SNMP simple," and recommends that the MIB working
group take as its starting inputs the MIB definitions found in the
High-Level Entity Management Systems (HEMS) RFC 1024 [5], the initial
SNMP specification [6], and the CMIS/CMIP memos [7,8].
Thus, the list of managed objects defined here, has been derived by
taking only those elements which are considered essential. Since
such elements are essential, there is no need to allow the
implementation of individual objects, to be optional. Rather, all
compliant implementations will contain all applicable (see below)
objects defined in this memo.
This approach of taking only the essential objects is NOT
restrictive, since the SMI defined in the companion memo provides
three extensibility mechanisms: one, the addition of new standard
objects through the definitions of new versions of the MIB; two, the
addition of widely-available but non-standard objects through the
multilateral subtree; and three, the addition of private objects
through the enterprises subtree. Such additional objects can not only
be used for vendor-specific elements, but also for experimentation as
required to further the knowledge of which other objects are
essential.
The primary criterion for being considered essential was for an
object to be contained in all of the above referenced MIB
definitions. A few other objects have been included, but only if the
MIB working group believed they are truly essential. The detailed
list of criteria against which potential inclusions in this (initial)
MIB were considered, was:
1) An object needed to be essential for either fault or
configuration management.
2) Only weak control objects were permitted (by weak, it
is meant that tampering with them can do only limited
damage). This criterion reflects the fact that the
current management protocols are not sufficiently secure
to do more powerful control operations.
3) Evidence of current use and utility was required.
4) An attempt was made to limit the number of objects to
about 100 to make it easier for vendors to fully
McCloghrie & Rose [Page 3]
RFC 1066 MIB August 1988
instrument their software.
5) To avoid redundant variables, it was required that no
object be included that can be derived from others in the
MIB.
6) Implementation specific objects (e.g., for BSD UNIX)
were excluded.
7) It was agreed to avoid heavily instrumenting critical
sections of code. The general guideline was one counter
per critical section per layer.
McCloghrie & Rose [Page 4]
RFC 1066 MIB August 1988
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined using Abstract Syntax Notation One (ASN.1) [9].
The mechanisms used for describing these objects are specified in the
companion memo. In particular, each object has a name, a syntax, and
an encoding. The name is an object identifier, an administratively
assigned name, which specifies an object type. 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 OBJECT DESCRIPTOR, to also
refer to the object type.
The syntax of an object type defines the abstract data structure
corresponding to that object type. The ASN.1 language is used for
this purpose. However, the companion memo purposely restricts the
ASN.1 constructs which may be used. These restrictions are
explicitly made for simplicity.
The encoding of an object type is simply how that object type is
represented using the object type's syntax. Implicitly tied to the
notion of an object type's syntax and encoding is how the object type
is represented when being transmitted on the network. This memo
specifies the use of the basic encoding rules of ASN.1 [10].
Since this list of managed objects contains only the essential
elements, there is no need to allow individual objects to be
optional. Rather, the objects are arranged into the following
groups:
- System
- Interfaces
- Address Translation
- IP
- ICMP
- TCP
- UDP
- EGP
There are two reasons for defining these groups: one, to provide a
means of assigning object identifiers; two, to provide a method for
implementations of managed agents to know which objects they must
implement. This method is as follows: if the semantics of a group is
applicable to an implementation, then it must implement all objects
McCloghrie & Rose [Page 5]
RFC 1066 MIB August 1988
in that group. For example, an implementation must implement the EGP
group if and only if it implements the EGP protocol.
The next section contains the specification of all object types
contained in the MIB. Following the conventions of the companion
memo, the object types are defined using the following fields:
OBJECT:
-------
A textual name, termed the OBJECT DESCRIPTOR, for the
object type, along with its corresponding OBJECT
IDENTIFIER.
Syntax:
The abstract syntax for the object type, presented using
ASN.1. This must resolve to an instance of the ASN.1
type ObjectSyntax defined in the SMI.
Definition:
A textual description of the semantics of the object
type. Implementations should ensure that their
interpretation of the object type fulfills this
definition since this MIB is intended for use in multi-
vendor environments. As such it is vital that object
types have consistent meaning across all machines.
Access:
One of read-only, read-write, write-only, or
not-accessible.
Status:
One of mandatory, optional, or obsolete.

example, if vendor "Flintstones, Inc." was assigned the
subtree 1.3.6.1.4.1.42, it could assign the identifier
1.3.6.1.4.1.42.1.1 to its "Fred Router".

Implementation of the Address Translation group is mandatory
for all systems.
The Address Translation group contains one table which is the
union across all interfaces of the translation tables for
converting a NetworkAddress (e.g., an IP address) into a
subnetwork-specific address. For lack of a better term, this
document refers to such a subnetwork-specific address as a
"physical" address.
Examples of such translation tables are: for broadcast media
where ARP is in use, the translation table is equivalent to
the ARP cache; or, on an X.25 network where non-algorithmic
translation to X.121 addresses is required, the translation
table contains the NetworkAddress to X.121 address
equivalences.
OBJECT:
-------
atTable { at 1 }
Syntax:
SEQUENCE OF AtEntry
Definition:
The Address Translation tables contain the NetworkAddress
to "physical" address equivalences. Some interfaces do
not use translation tables for determining address
equivalences (e.g., DDN-X.25 has an algorithmic method);
if all interfaces are of this type, then the Address
Translation table is empty, i.e., has zero entries.
