Abstract
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
In particular, it defines objects for managing IEEE 802.3 10 and 100
Mb/second baseband repeaters based on IEEE Std 802.3 Section 30, "10
& 100 Mb/s Management," October 26, 1995.

1. The SNMP Network Management Framework
The SNMP Network Management Framework presently consists of three
major components. They are:
o the SMI, described in RFC1902 [6] - the mechanisms used
for describing and naming objects for the purpose of
management.
o the MIB-II, STD 17, RFC1213 [5] - the core set of
managed objects for the Internet suite of protocols.
o the protocol, STD 15, RFC1157 [10] and/or RFC1905
[9] - the protocol used for accessing managed information.
Textual conventions are defined in RFC1903 [7], and conformance
statements are defined in RFC1904 [8].
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
2.1. Relationship to RFC1516
This MIB is intended as a superset of that defined by RFC1516 [11],
which will go to historic status. This MIB includes all of the
objects contained in that MIB, plus several new ones which provide
for significant additional capabilities. Implementors are encouraged
to support all applicable conformance groups in order to make the
best use of the new functionality provided by this MIB. The new
objects provide support for:
o multiple repeaters
o 100BASE-T management
o port TopN capability
o address search and topology mapping
Certain objects have been deprecated; in particular, those scalar
objects used for managing a single repeater are now of minimal use
since they are duplicated in the new multiple- repeater definitions.
Additional objects have been deprecated based on implementation
experience with RFC1516.
2.2. Repeater Management
Instances of the object types defined in this memo represent
attributes of an IEEE 802.3 (Ethernet-like) repeater, as defined by
Section 9, "Repeater Unit for 10 Mb/s Baseband Networks" in the IEEE
802.3/ISO 8802-3 CSMA/CD standard [1], and Section 27, "Repeater for
100 Mb/s Baseband Networks" in the IEEE Standard 802.3u-1995 [2].
These Repeater MIB objects may be used to manage non-standard
repeater-like devices, but defining objects to describe
implementation-specific properties of non-standard repeater- like
devices is outside the scope of this memo.
The definitions presented here are based on Section 30.4, "Layer
Management for 10 and 100 Mb/s Baseband Repeaters" and Annex 30A,
"GDMO Specificataions for 802.3 managed objects" of [3].
Implementors of these MIB objects should note that [3] explicitly
describes when, where, and how various repeater attributes are
measured. The IEEE document also describes the effects of repeater
actions that may be invoked by manipulating instances of the MIB
objects defined here.
The counters in this document are defined to be the same as those
counters in [3], with the intention that the same instrumentation can
be used to implement both the IEEE and IETF management standards.
2.3. Structure of the MIB
Objects in this MIB are arranged into packages, each of which
contains a set of related objects within a broad functional category.
Objects within a package are generally defined under the same OID
subtree. These packages are intended for organizational convenience
ONLY, and have no relation to the conformance groups defined later in
the document.
2.3.1. Basic Definitions
The basic definitions include objects which are applicable to all
repeaters: status, parameter and control objects for each repeater
within the managed system, for the port groups within the system, and
for the individual ports themselves.
2.3.2. Monitor Definitions
The monitor definitions include monitoring statistics for each
repeater within the system and for individual ports.
2.3.3. Address Tracking Definitions
This collection includes objects for tracking the MAC addresses of
the DTEs attached to the ports within the system and for mapping the
topology of a network.
Note: These definitions are based on a technology which has been
patented by Hewlett-Packard Company. HP has granted rights to this
technology to implementors of this MIB. See [12] and [13] for
details.
2.3.4. Top N Definitions
These objects may be used for tracking the ports with the most
activity within the system or within particular repeaters.
2.4. Relationship to Other MIBs
2.4.1. Relationship to MIB-II
It is assumed that a repeater implementing this MIB will also
implement (at least) the 'system' group defined in MIB-II [5].
2.4.1.1. Relationship to the 'system' group
In MIB-II, the 'system' group is defined as being mandatory for all
systems such that each managed entity contains one instance of each
object in the 'system' group. Thus, those objects apply to the
entity even if the entity's sole functionality is management of
repeaters.
2.4.1.2. Relationship to the 'interfaces' group
In MIB-II, the 'interfaces' group is defined as being mandatory for
all systems and contains information on an entity's interfaces, where
each interface is thought of as being attached to a 'subnetwork'.
(Note that this term is not to be confused with 'subnet' which refers
to an addressing partitioning scheme used in the Internet suite of
protocols.)
This Repeater MIB uses the notion of ports on a repeater. The
concept of a MIB-II interface has NO specific relationship to a
repeater's port. Therefore, the 'interfaces' group applies only to
the one (or more) network interfaces on which the entity managing the
repeater sends and receives management protocol operations, and does
not apply to the repeater's ports.
This is consistent with the physical-layer nature of a repeater. A
repeater is a bitwise store-and-forward device. It recognizes
activity and bits, but does not process incoming data based on any
packet-related information (such as checksum or addresses). A
repeater has no MAC address, no MAC implementation, and does not pass
packets up to higher-level protocol entities for processing.
(When a network management entity is observing a repeater, it may
appear as though the repeater is passing packets to a higher-level
protocol entity. However, this is only a means of implementing
management, and this passing of management information is not part of
the repeater functionality.)

DESCRIPTION
"Management information for 802.3 repeaters.
The following references are used throughout
this MIB module:
[IEEE 802.3 Std]
refers to IEEE 802.3/ISO 8802-3 Information
processing systems - Local area networks -
Part 3: Carrier sense multiple access with
collision detection (CSMA/CD) access method
and physical layer specifications (1993).
[IEEE 802.3 Mgt]
refers to IEEE 802.3u-1995, '10 Mb/s &
100 Mb/s Management, Section 30,'
Supplement to ANSI/IEEE 802.3.
The following terms are used throughout this
MIB module. For complete formal definitions,
the IEEE 802.3 standards should be consulted
wherever possible:
System - A managed entity compliant with this
MIB, and incorporating at least one managed
802.3 repeater.
Chassis - An enclosure for one managed repeater,
part of a managed repeater, or several managed
repeaters. It typically contains an integral
power supply and a variable number of available
module slots.
Repeater-unit - The portion of the repeater set
that is inboard of the physical media interfaces.
The physical media interfaces (MAUs, AUIs) may be
physically separated from the repeater-unit, or
they may be integrated into the same physical
package.
Trivial repeater-unit - An isolated port that can
gather statistics.
Group - A recommended, but optional, entity
defined by the IEEE 802.3 management standard,
in order to support a modular numbering scheme.
The classical example allows an implementor to
represent field-replaceable units as groups of
ports, with the port numbering matching the
modular hardware implementation.
System interconnect segment - An internal
segment allowing interconnection of ports
belonging to different physical entities
into the same logical manageable repeater.
Examples of implementation might be
backplane busses in modular hubs, or
chaining cables in stacks of hubs.
Stack - A scalable system that may include
managed repeaters, in which modularity is
achieved by interconnecting a number of
different chassis.
Module - A building block in a modular
chassis. It typically maps into one 'slot';
however, the range of configurations may be
very large, with several modules entering
one slot, or one module covering several
slots.

DESCRIPTION
"********* THIS OBJECT IS DEPRECATED **********
The rptrGroupCapacity is the number of groups
that can be contained within the repeater. Within
each managed repeater, the groups are uniquely
numbered in the range from 1 to rptrGroupCapacity.
Some groups may not be present in the repeater, in
which case the actual number of groups present
will be less than rptrGroupCapacity. The number
of groups present will never be greater than
rptrGroupCapacity.
Note: In practice, this will generally be the
number of field-replaceable units (i.e., modules,
cards, or boards) that can fit in the physical
repeater enclosure, and the group numbers will
correspond to numbers marked on the physical
enclosure."

section 9 [IEEE 802.3 Std] for a 10Mb/s repeater,
and the START state of Fig 27-2 in section 27
of that standard for a 100Mb/s repeater.
Setting this object to noReset(1) has no effect.
The agent will always return the value noReset(1)
when this object is read.
After receiving a request to set this variable to
reset(2), the agent is allowed to delay the reset
for a short period. For example, the implementor
may choose to delay the reset long enough to allow
the SNMP response to be transmitted. In any
event, the SNMP response must be transmitted.
This action does not reset the management counters
defined in this document nor does it affect the
portAdminStatus parameters. Included in this
action is the execution of a disruptive Self-Test
with the following characteristics: a) The nature
of the tests is not specified. b) The test resets
the repeater but without affecting management
information about the repeater. c) The test does
not inject packets onto any segment. d) Packets
received during the test may or may not be
transferred. e) The test does not interfere with
management functions.
After performing this self-test, the agent will
update the repeater health information (including
rptrOperStatus and rptrHealthText), and send a

"This object indicates the port's operational
status. The notPresent(3) status indicates the
port is physically removed (note this may or may
not be possible depending on the type of port.)
The operational(1) status indicates that the port
is enabled (see rptrPortAdminStatus) and working,
even though it might be auto-partitioned (see
rptrPortAutoPartitionState).
If this object has the value operational(1) and
rptrPortAdminStatus is set to disabled(2), it is

DESCRIPTION
"Setting this object to reset(2) causes a

and to the START state of Fig 27-2 in section 27
of that standard for a 100Mb/s repeater.
Setting this object to noReset(1) has no effect.
The agent will always return the value noReset(1)
when this object is read.
After receiving a request to set this variable to
reset(2), the agent is allowed to delay the reset
for a short period. For example, the implementor
may choose to delay the reset long enough to allow
the SNMP response to be transmitted. In any
event, the SNMP response must be transmitted.
This action does not reset the management counters
defined in this document nor does it affect the
portAdminStatus parameters. Included in this
action is the execution of a disruptive Self-Test
with the following characteristics: a) The nature
of the tests is not specified. b) The test resets
the repeater but without affecting management
information about the repeater. c) The test does
not inject packets onto any segment. d) Packets
received during the test may or may not be
transferred. e) The test does not interfere with
management functions.
After performing this self-test, the agent will
update the repeater health information (including
rptrInfoOperStatus), and send a rptrInfoResetEvent
notification."
