2. Abstract
This memo defines an experimental portion of the Management
Information Base (MIB) for use with network management
protocols in TCP/IP-based internets. In particular, it
defines objects for managing devices which implement the FDDI,
as specified in the ANSI SMT 7.3 draft standard.
This memo does not specify a standard for the Internet
community.

3. Historical Perspective
As reported in RFC 1052, IAB Recommendations for the
Development of Internet Network Management Standards [1], a
two-prong strategy for network management of TCP/IP-based
internets was undertaken. In the short-term, the Simple
Network Management Protocol (SNMP), defined in RFC 1067, was
to be used to manage nodes in the Internet community. In the
long-term, the use of the OSI network management framework was
to be examined. Two documents were produced to define the
management information: RFC 1065, which defined the Structure
of Management Information (SMI), and RFC 1066, which defined
the Management Information Base (MIB). Both of these
documents were designed so as to be compatible with both the
SNMP and the OSI network management framework.
This strategy was quite successful in the short-term:
Internet-based network management technology was fielded, by
both the research and commercial communities, within a few
months. As a result of this, portions of the Internet
community became network manageable in a timely fashion.
As reported in RFC 1109, Report of the Second Ad Hoc Network
Management Review Group [2], the requirements of the SNMP and
the OSI network management frameworks were more different than
anticipated. As such, the requirement for compatibility
between the SMI/MIB and both frameworks was suspended. This
action permitted the operational network management framework,
based on the SNMP, to respond to new operational needs in the
Internet community by producing MIB-II.
In May of 1990, the core documents were elevated to "Standard
Protocols" with "Recommended" status. As such, the Internet-
standard network management framework consists of: Structure
and Identification of Management Information for TCP/IP-based
internets, RFC 1155 [3], which describes how managed objects
contained in the MIB are defined; Management Information Base
for Network Management of TCP/IP-based internets, which
describes the managed objects contained in the MIB, RFC 1156
[4]; and, the Simple Network Management Protocol, RFC 1157
[5], which defines the protocol used to manage these objects.
Consistent with the IAB directive to produce simple, workable
systems in the short-term, the list of managed objects defined
in the Internet-standard MIB was derived by taking only those
J. D. Case/A. Rijsinghani [Page 3]
Internet Draft FDDI MIB March 1993
elements which are considered essential. However, the SMI
defined 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 experimental 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.
This memo defines extensions to the MIB using the second
method. It contains definitions of managed objects used for
experimentation.

Internet Draft FDDI MIB March 1993
4. Objects
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) [5] defined in the SMI. 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 SMI [1]
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.
The SMI specifies the use of the basic encoding rules of ASN.1
[6], subject to the additional requirements imposed by the
SNMP.
4.1. Format of Definitions
Section 6 contains contains the specification of all object
types contained in this MIB module. The object types are
defined using the conventions defined in the SMI, as amended
by the extensions specified in [7].

Internet Draft FDDI MIB March 1993
5. Overview
This document defines the managed objects for FDDI devices
which are to be accessible via the Simple Network Management
Protocol (SNMP). At present, this applies to these values of
the ifType variable in the Internet-standard MIB:
fddi(15)
For these interfaces, the value of the ifSpecific variable in
the MIB-II [4] has the OBJECT IDENTIFIER value:
smt73 OBJECT IDENTIFIER ::= { experimental 8 73 }
The definitions of the objects presented here draws heavily
from related work in the ANSI X3T9.5 committee and the SMT
subcommittee of that committee [8]. In fact, the definitions
of the managed objects in this document are, to the maximum
extent possible, identical to those identified by the ANSI
committee. The semantics of each managed object should be the
same with syntactic changes made as necessary to recast the
objects in terms of the Internet-standard SMI and MIB so as to
be compatible with the SNMP. Examples of these syntactic
changes include remapping booleans to enumerated integers,
remapping bit strings to octet strings, and the like. In
addition, the naming of the objects was changed to achieve
compatibility.
These minimal syntactic changes with no semantic changes
should allow implementations of SNMP manageable FDDI systems
to share instrumentation with other network management schemes
and thereby minimize implementation cost. In addition, the
translation of information conveyed by managed objects from
one network management scheme to another is eased by these
shared definitions.
Only the essential variables, as indicated by their mandatory
status in the ANSI specification were retained in this
document. The importance of variables which have an optional
status in the ANSI specification were perceived as being less
widely accepted.

5.1. Textual Conventions
Several new datatypes are introduced as a textual convention
in this MIB document. These textual conventions enhance the
readability of the document and ease comparisons with its ANSI
counterpart. It should be noted that the introduction of the
following textual conventions has no effect on either the
syntax nor the semantics of any managed objects. The use of
these is merely an artifact of the explanatory method used.
Objects defined in terms of one of these methods are always
encoded by means of the rules that define the primitive type.
Hence, no changes to the SMI or the SNMP are necessary to
accommodate these textual conventions which are adopted merely
for the convenience of readers and writers in pursuit of the
elusive goal of clear, concise, and unambiguous MIB documents.
6. Changes from RFC-1285
The changes from RFC-1285 to this document, based on changes
from ANSI SMT 6.2 to SMT 7.3, were so numerous that this MIB
is located on a different branch of the MIB tree. No
assumptions should be made about compatibility with RFC-1285.

-- textual conventions
FddiTimeNano ::= INTEGER (0..2147483647)
-- This data type specifies 1 nanosecond units as
-- an integer value.
--
-- NOTE: The encoding is normal integer representation, not
-- two's complement. Since this type is used for variables
-- which are encoded as TimerTwosComplement in the ANSI
-- specification, two operations need to be performed on such
-- variables to convert from ANSI form to SNMP form:
--
-- 1) Convert from two's complement to normal integer representation
-- 2) Multiply by 80 to convert from 80 nsec to 1 nsec units
--
-- No resolution is lost. Moreover, the objects for which this
-- data type is used effectively do not lose any range due to the
-- lower maximum value since they do not require the full range.
--
-- Example: If smt73MACTReq had a value of 8 ms, it would
-- be stored in ANSI TimerTwosComplement format as 0xFFFE7960
-- [8 ms is 100000 in 80 nsec units, which is then converted to
-- two's complement] but be reported as 8000000 in SNMP since it
-- is encoded here as FddiTimeNano.
FddiTimeMilli ::= INTEGER (0..2147483647)
-- This data type is used for some FDDI timers. It specifies
-- time in 1 millisecond units, in normal integer representation.
FddiResourceId ::= INTEGER (0..65535)
-- This data type is used to refer to an instance of a MAC,
-- PORT, or PATH Resource ID. Indexing begins
-- at 1. Zero is used to indicate the absence of a resource.
FddiSMTStationIdType ::= OCTET STRING (SIZE (8))
-- The unique identifier for the FDDI station. This is a
-- string of 8 octets, represented as X' yy yy xx xx xx xx xx xx'
-- with the low order 6 octet (xx) from a unique IEEE
-- assigned address. The high order two bits of the IEEE
-- address, the group address bit and the administration bit
-- (Universal/Local) bit should both be zero. The first two
-- octets, the yy octets, are implementor-defined.
--
-- The representation of the address portion of the station id
-- is in the IEEE (ANSI/IEEE P802.1A) canonical notation for
J. D. Case/A. Rijsinghani [Page 9]
Internet Draft FDDI MIB March 1993
-- 48 bit addresses. The canonical form is a 6-octet string
-- where the first octet contains the first 8 bits of the
-- address, with the I/G(Individual/Group) address bit as the
-- least significant bit and the U/L (Universal/Local) bit
-- as the next more significant bit, and so on. Note that
-- addresses in the ANSI FDDI standard SMT frames are
-- represented in FDDI MAC order.
FddiMACLongAddressType ::= OCTET STRING (SIZE (6))
-- The representation of long MAC addresses as management
-- values is in the IEEE (ANSI/IEEE P802.1A) canonical
-- notation for 48 bit addresses. The canonical form is a

"This object, when read, always returns a value of
other(1). The behavior of setting this variable
to each of the acceptable values is as follows:
other(1): Results in a badValue error.
connect(2): Generates a Connect signal to ECM
to begin a connection sequence. The
fddiSMTRemoteDisconnectFlag is cleared
on the setting of this variable to 1.
See ANSI Ref 9.4.2.
disconnect(3): Generates a Disconnect signal
to ECM and sets the
fddiSMTRemoteDIsconnectFlag. see ANSI
Ref 9.4.2.
path-Test(4): Initiates a station Path_Test.
The Path_Test variable (see ANSI Ref
9.4.1) is set to 'Testing'. The results
of this action are not specified in this
standard.
self-Test(5): Initiates a station Self_Test.
The results of this action are not
specified in this standard.
disable-a(6): Causes a PC_Disable on the A
port if the A port mode is peer.
disable-b(7): Causes a PC_Disable on the B
port if the B port mode is peer.
disable-m(8): Causes a PC_Disable on all M
ports.
Attempts to set this object to all other values
results in a badValue error. The result of
setting this variable to path-Test(4) or self-
Test(5) is implementation-specific."
