1. Introduction

This memo defines a set of DECnet Phase IV extensions that have been
created for the Internet MIB. It reflects changes which are the
result of operational eXPerience based on RFC1289.

When used in conjunction with the structure of management information
(STD 16, RFC1155), the management information base for network
management of TCP/IP-based internets (STD 17, RFC1213) and the
Simple Network Management Protocol (STD 15, RFC1157), it will be
possible to provide integrated network management of combined TCP/IP
and DECnet Phase IV based internets. This document was produced by
the DECnet Phase IV MIB working group of the Internet Engineering
Task Force (IETF).

With the adoption of The Simple Network Management Protocol (STD 15,
RFC1157), the management information base for network management of
TCP/IP-based internets (STD 17, RFC1213), and the structure of

management information (STD 16, RFC1155), by the Internet, and a
large number of vendor implementations of these standards in
commercially available products, it became possible to provide a
higher level of effective network management in TCP/IP-based
internets than previously available. With the growth in the use of
these standards, network managers desired to use this environment as
a base for providing integrated network management of multi-protocol
networks.

DECnet Phase IV is one widely used protocol which often coexists in
IP-based internets. This memo provides the mechanisms by which IP-
based management stations can effectively manage DECnet Phase IV
based systems (especially router products) in an integrated fashion
through the use of the standard Internet SMI, MIB and Simple Network
Management Protocol.

DECnet Phase IV objects have been defined to be used in conjunction
with the Internet MIB to allow Access and control of these new
objects by the Internet community. Additional support for other
DECnet-based protocols such as RBMS (Remote Bridge Management
Software) or other Digital Equipment Corporation specific hardware
platforms is not included in this document.

2. The Network Management Framework

The Internet-standard Network Management Framework consists of three
components. They are:

o STD 16, RFC1155 which defines the SMI, the mechanisms used for
describing and naming objects for the purpose of management.
STD 16, RFC1212 defines a more concise description mechanism,
which is wholly consistent with the SMI.

o STD 17, RFC1213 defines MIB-II, the core set of managed objects
for the Internet suite of protocols.

o STD 15, RFC1157 which defines the SNMP, the protocol used for
network access to managed objects.

The Framework permits new objects to be defined for the purpose of
experimentation and evaluation.

2.1 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.

3. Selected Objects

The objects included in this memo have been created from the DIGITAL
Network Architecture Network Management Functional Specification
Version 4.0.0, dated July 1983. An attempt has been made to provide a
reasonable ordering of these variables into groups. These groups are:

System Group
Network Management Group
Session Group
End Group
Routing Group
Circuit Group
DDCMP Group
DDCMP Multipoint Control Group
Ethernet Group
Counters Group
Adjacency Group
Line Group
Non Broadcast Line Group
Area Group

An effort has also been made to preserve the original syntax of each
object wherever possible, for example, a DECnet Phase IV object is
Executor State. This was originally coded as a NICE (Network
Information and Control Exchange) data type which is a coded single
field object of 1 byte in length. When converted for inclusion into
the Internet MIB using the Internet SMI, it became an enumerated
integer.

All objects in this memo are described using the standard Internet
SMI and BER of STD 16, RFC1155. A complete description of an object
will include the name, syntax and encoding. Just as with objects
supported in the MIB (STD 17, RFC1213), an object name is identified
with an object identifier which has been administratively assigned.
This identifies an Object Type. When an object type is combined with
a specific instance, the particular object is uniquely identified.
The use of Object Descriptors in this memo is consistent with that of
STD 17, RFC1213 - they are text strings meant to be read by humans.
The descriptors have been taken from the original DIGITAL Network
Architecture Network Management Functional Specification Version
4.0.0 Dated July 1983 which defined DECnet Phase IV objects. These

names were then massaged to put them in a form as consistent as
possible with object type names listed in the standard Internet MIB.
Object defintion information is also taken directly from the Network
Architecture Network Managment Functional Specification cited above
wherever possible. In this document, EXECUTOR is intended to
reference only the DECnet software and is not intended to effect any
other protocols which may be running on the system.

4. Textual Conventions

New datatypes have been introduced as a textual conventions in this
DECnet Phase IV MIB document. The purpose of these additions is to
facilitate understanding of new objects in this MIB. No changes to
the SMI or the SNMP are necessary to support these conventions which
are described in 5 (Definitions).

the parameter definition in Phase III, which included
the Routing overhead.) It does not include Routing or
Data link overhead (except for the constant value of
6). There is one buffer size for all circuits.

NOTE: The BUFFER SIZE defines the maximum size messages
that the Routing layer can forward. The SEGMENT BUFFER
SIZE (defined below) defines the maximum size messages
that the End Communication layer can transmit or
receive. The SEGMENT BUFFER SIZE is always less than
or equal to the BUFFER SIZE. Normally the two

decision algorithm declares another node unreachable
because the cost of the least costly path to the
other node is excessive. For correct operation, this
parameter must not be less than the maximum path cost
of the network."

circuit between two adjacent nodes.) This parameter
defines the point where the executor node's Routing
routing decision algorithm declares another node
unreachable because the length of the shortest path
between the two nodes is too long. For correct
operation, this parameter must not be less than the

SYNTAX PhivAddr -- OCTET STRING (SIZE (2))
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The next node on the circuit used to get to the
area under scrutiny."

ACCESS read-write
STATUS mandatory
DESCRIPTION
"This value represents the maximum total path cost
allowed from the executor to any other level 2 routing
node. The AREA MAXIMUM COST number is decimal in the
range 1-1022. This parameter is only applicable if
the executor node is of type AREA."
::= { area 2 }

phivAreaMaxHops OBJECT-TYPE

6. Changes from RFC1289

Several changes have been made to this document. These changes
include:

(1) Ranges have been added on all PhivCounter types to remove
ambiguity which might otherwise have occurred.

(2) Made clear that all indexes start with 1 and count up.

(3) Spelling and typographic changes.

(4) Changes to improve consistency with other documents including
the removal of subranging within definitions of sequences
defining table entries.

(5) Updated compliance text to conform to current practice.

(6) Fixed discrepancy between description and range clause for
phivControlMaxBuffs.

(7) Added a space that was missing between SYNTAX and INTEGER in the
phivRouteType object.

(8) Both phivRouteType and phivRouteSystemAddr have been made
obsolete. They have been replaced with phivRouteRoutingType
and phivRouteSystemAddress which are both read-write objects.

(9) A new Adjacency table has been added as adjacency 2. This
table is identical to the original except that
phivAdjExecListenTimer was not carried into the new version.
The existing Adjacency table and all objects in it have been
made obsolete. The index to the new table is
phivAdjNodeCircuitIndex and phivAdjAddr.

(10) Objects phivCountersCountDataBlocksRecd and
phivCountersCountDataBlocksSent have both been made obsolete
since the DESCRIPTION information overlapped with the
phivCountersCountDataBlksRecd and
phivCountersCountDataBlksSent objects which have been
retained.

(11) The following groups have been moved from mandatory to
optional status: Session, End, DDCMP, DDCMP Multipoint
Circuit Control, Counters, and Non Broadcast Line.
