Abstract
This memo defines an experimental 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.
This memo does not specify a standard for the Internet
community.
1. The SNMPv2 Network Management Framework
The SNMPv2 Network Management Framework consists of four major
components. They are:
o RFC 1442 which defines the SMI, the mechanisms used for
describing and naming objects for the purpose of
management.
o STD 17, RFC 1213 defines MIB-II, the core set of managed
objects for the Internet suite of protocols.
o RFC 1445 which defines the administrative and other
architectural aspects of the framework.
o RFC 1448 which defines 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
Expires June 1996 [Page 2]
Internet Draft 802.3 Repeater MIB 27 November 1995
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.

Internet Draft 802.3 Repeater MIB 27 November 1995
2. Overview
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.
2.1. Structure of the MIB
Objects in this MIB are arranged into MIB groups. Each MIB
group is organized as a set of related objects.
2.1.1. The Basic Group Definitions
This group contains the objects which are applicable to all
repeaters. It contains status, parameter and control objects
for each repeater within the managed system, for the port
groups within the system, and for the individual ports
Expires June 1996 [Page 4]
Internet Draft 802.3 Repeater MIB 27 November 1995
themselves.
2.1.2. The Monitor Group Definitions
This group contains monitoring statistics for each repeater
within the system and for individual ports.
2.1.3. The Address Tracking Group Definitions
This group contains objects for tracking the MAC addresses of
the DTEs attached to the ports within the system.
2.1.4. The Top N Group Definitions
This group contains objects for tracking the ports with the
most activity within the system or within particular
repeaters.
2.2. Relationship to Other MIBs
2.2.1. Relationship to RFC 1516
This MIB is intended as a superset of that defined by RFC
1516, which will go to historic status. This MIB includes all
of the objects contained in that MIB, plus some additional
ones, mainly for support for multiple repeaters and for
100BASE-T management. 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 rptrInfoTable and rptrMonitorTable definitions.
2.2.2. 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].
2.2.2.1. 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
Expires June 1996 [Page 5]
Internet Draft 802.3 Repeater MIB 27 November 1995
functionality is management of repeaters.
2.2.2.2. 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.)

of groups present will never be greater than
rptrGroupCapacity.
Note: In practice, this will generally be the

cards, or boards) that can fit in the physical
repeater enclosure, and the group numbers will
correspond to numbers marked on the physical
enclosure."

operation resumes.
The admin status takes precedence over auto-
partition and functionally operates between the
auto-partition mechanism and the AUI/PMA.
Setting this object to enabled(1) enables the port
and exerts a BEGIN on the port's auto-partition
state machine.
(In effect, when a port is disabled, the value of
rptrPortAutoPartitionState for that port is frozen
until the port is next enabled. When the port
becomes enabled, the rptrPortAutoPartitionState
becomes notAutoPartitioned(1), regardless of its
pre-disabling state.)"

"This object indicates the port's operational

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

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

signal is not asserted (10Mb/s operation) or
Expires June 1996 [Page 39]

the Collision Count Increment state of the
partition state diagram (fig 27-8 of
[IEEE 802.3 Std]) has not been entered
(100Mb/s operation). 2) The ActivityDuration
is greater than ValidPacketMinTime. 3) The
frequency (data rate) is detectably mismatched
from the local transmit frequency.
Measurement method B: 1) The CollisionEvent
signal is not asserted (10Mb/s operation)
or the Collision Count Increment state of the
partition state diagram (fig 27-8 of
[IEEE 802.3 Std]) has not been entered
(100Mb/s operation). 2) The OctetCount is
greater than 63. 3) The frequency (data
rate) is detectably mismatched from the local
transmit frequency. The exact degree of
mismatch is vendor specific and is to be
defined by the vendor for conformance testing.
When this event occurs, other counters whose
increment conditions were satisfied may or may not
also be incremented, at the implementor's
discretion. Whether or not the repeater was able
to maintain data integrity is beyond the scope of
this standard.
A discontinuity may occur in the value
when the value of object
rptrMonitorPortLastChange changes."

"The total number of errors which have occurred on

rptrMonitorPortAlignmentErrors,
rptrMonitorPortFrameTooLongs,

rptrMonitorPortLateEvents,
rptrMonitorPortVeryLongEvents, and
rptrMonitorPortDataRateMismatches.
This counter is redundant in the sense that it is
the summation of information already available
through other objects. However, it is included
specifically because the regular retrieval of this
object as a means of tracking the health of a port
provides a considerable optimization of network
management traffic over the otherwise necessary
retrieval of the summed counters.
Note that rptrMonitorPortRunts is not included
in this total; this is because runts usually
indicate collision fragments, a normal network
event.

[Editor's note: This sum does not include the
value of the rptrMonitorPortSymbolErrors object.
Perhaps we should deprecate it and define a new

may need to address the rollover issue in that
case.]
This object is a delta value, providing the

DESCRIPTION
"In a system containing a single managed repeater,

related to the operational status of the repeater.
It is sent either when the value of
rptrOperStatus changes, or upon completion of a
non-disruptive test.
Expires June 1996 [Page 61]
Internet Draft 802.3 Repeater MIB 27 November 1995
The rptrHealth notification must contain the
rptrOperStatus object. The agent may optionally
include the rptrHealthText object in the varBind
list. See the rptrOperStatus and rptrHealthText
objects for descriptions of the information that
is sent.
The agent must throttle the generation of
consecutive rptrHealth traps so that there is at
least a five-second gap between traps of this
type. When traps are throttled, they are dropped,
not queued for sending at a future time. (Note
that 'generating' a trap means sending to all
configured recipients.)"

rptrGroupChange NOTIFICATION-TYPE
OBJECTS { rptrGroupIndex }
STATUS deprecated
DESCRIPTION
"In a system containing a single managed repeater,
this notification is sent when a change occurs in the
group structure of the repeater. This occurs only
when a group is logically or physically removed
from or added to a repeater. The varBind list
contains the identifier of the group that was
removed or added.
The agent must throttle the generation of
consecutive rptrGroupChange traps for the same
group so that there is at least a five-second gap
between traps of this type. When traps are
throttled, they are dropped, not queued for
sending at a future time. (Note that 'generating'
a trap means sending to all configured
recipients.)"

rptrResetEvent NOTIFICATION-TYPE
Expires June 1996 [Page 62]
Internet Draft 802.3 Repeater MIB 27 November 1995
OBJECTS { rptrOperStatus }
STATUS deprecated
DESCRIPTION
"In a system containing a single managed repeater-unit,
the rptrResetEvent notification conveys information
related to the operational status of the repeater.
This trap is sent on completion of a repeater
reset action. A repeater reset action is defined
as an a transition to the START state of Fig 9-2
in section 9 [IEEE 802.3 Std], when triggered by a
management command (e.g., an SNMP Set on the
rptrReset object).
The agent must throttle the generation of
consecutive rptrResetEvent traps so that there is
at least a five-second gap between traps of this
type. When traps are throttled, they are dropped,
not queued for sending at a future time. (Note
that 'generating' a trap means sending to all
configured recipients.)
The rptrResetEvent trap is not sent when the agent
restarts and sends an SNMP coldStart or warmStart
trap. However, it is recommended that a repeater
agent send the rptrOperStatus object as an
optional object with its coldStart and warmStart
trap PDUs.
The rptrOperStatus object must be included in the
varbind list sent with this trap. The agent may
optionally include the rptrHealthText object as
well."
