1. 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 100Mb/second repeaters based on IEEE 802.12.
This memo does not specify a standard for the Internet community.
2. 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.
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 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. Overview
Instances of these object types represent attributes of an IEEE
802.12 (100VG-AnyLAN) repeater, as defined by Section 12, "RMAC
John Flick Expires December 30, 1995 [Page 2]
Internet Draft IEEE 802.12 Repeater MIB June 30 1995
Protocol" in the IEEE 802.12 Demand Priority Access Method Standard
[6].
The definitions presented here are based on Section 13, "Layer
Management Functions and Services", and Annex E, "GDMO Specifications
for Demand Priority Managed Objects" of IEEE Standard 802.12 [6].
Implementors of these MIB objects should note that [6] explicitly
describes (in the form of Pascal pseudocode) 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 the IEEE 802.12 Standard, with the intention that the
same instrumentation can be used to implement both the IEEE and IETF
management standards.

DESCRIPTION
"Setting this object to reset(2) causes the
repeater to transition to its initial state as
specified in clause 12 [IEEE Std 802.12].
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 vgRptrPortAdminStatus parameters.
Included in this action is the execution of a
disruptive Self-Test with the following
characteristics:
1) The nature of the tests is not specified.
2) The test resets the repeater but without
affecting configurable management
information about the repeater.
3) Packets received during the test may or
may not be transferred.
4) The test does not interfere with
management functions.
After performing this self-test, the agent will
update the repeater health information (including
vgRptrHealthState and vgRptrHealthText), and send
a vgRptrResetEvent."

DESCRIPTION
"Setting this object to selfTest(2) causes the
repeater to perform an agent-specific,
non-disruptive self-test that has the following
characteristics:
1) The nature of the tests is not specified.
2) The test does not change the state of the
repeater or management information about
the repeater.
3) The test does not inject packets onto any
segment.
4) The test does not prevent the transfer of
any packets.
5) The test does not interfere with
management functions.
After performing this test, the agent will update
the repeater health information (including
vgRptrHealthState and vgRptrHealthText) and send a
vgRptrHealth.
Note that this definition allows returning an
'okay' result after doing a trivial test.
Setting this object to noSelfTest(1) has no
effect. The agent will always return the value
noSelfTest(1) when this object is read."

Note that the value 'someCablesBundled(1)' will
work in the vast majority of all installations,
regardless of whether or not any cables are
physically in a bundle, since promiscuous and
cascaded ports automatically avoid the store and
forward. The main situation in which
'noCablesBundled(2)' is beneficial is when there
is a large amount of multicast traffic and the
cables are not in a bundle. The value of this

"This security object is set by the network
manager to configure what type of device is
permitted to connect to the port. One of the
following values:
allowEndNodesOnly - only non-
promiscuous end
nodes permitted.
allowPromiscuousEndNodes - promiscuous or
non-promiscuous
end nodes

allowEndNodesOrRepeaters - repeaters or non-
promiscuous end

allowAnything - repeaters,

promiscuous or
non-promiscuous
end nodes
permitted
For a port for which vgRptrPortType is equal to
'cascadeInternal' or 'cascadeExternal', the
corresponding instance of this object may not be
set to 'allowEndNodesOnly' or
'allowPromiscuousEndNodes'.
The agent must reject a SET of this object if the
value includes no capabilities that are
supported by this port's hardware, as defined by
the values of the corresponding instances of
vgRptrPortSupportedPromiscMode and
vgRptrPortSupportedCascadeMode.
Note that vgRptrPortSupportPromiscMode and
vgRptrPortSupportedCascadeMode represent what the
port hardware is capable of supporting.
vgRptrPortAllowedTrainType is used for setting an
administrative policy for a port. The actual set
of training configurations that will be allowed
to succeed on a port is the intersection of what
the hardware will support and what is
administratively allowed. The above requirement
on what values may be set to this object says that
the intersection of what is supported and what is
allowed must be non-empty. In other words, it
must not result in a situation in which nothing
would be allowed to train on that port. However,
a value can be set to this object as long as the
combination of this object and what is supported
by the hardware would still leave at least one
configuration that could successfully train on the
port."

"This object is a count of the number of octets
contained in normal priority frames that have
been received on this port. This counter is
incremented by OctetCount for each frame received
on this port which is counted by
vgRptrPortNormPriorityFrames.
This counter is a 64 bit version of
vgRptrPortNormPriorityOctets. It should be used
by Network Management protocols which support 64
bit counters (e.g. SNMPv2)."

DESCRIPTION
"This object is used to search for a specified
MAC address. When this object is set, an address
search begins. This starts by initializing
vgRptrSearchState to 'none'.
When a valid frame is received with a source MAC
address which matches the current value of
vgRptrSearchAddress, the agent will update
vgRptrSearchState, vgRptrSearchGroup, and
vgRptrSearchPort to reflect the current status of
the search, and the group and port from which the
frame was received.
This capability can be used by a management
application to draw a topologically correct map
of a network which includes cascaded repeaters."

vgRptrSearchPort to reflect the group and port on
which the address was heard. If the agent
detects the address on more than one port, it
will set this object to 'many'."

The purpose of this object is to provide a means
for network management software to inform an end
station that it is using a duplicate station
address. Setting this object does not affect the
current state of the link; the end station will
not be informed of the duplicate address until it
retrains for some reason. Note that regardless
of its station address, the end station will not
be able to train successfully until the network

sent as a result of powering up a repeater.
The vgRptrHealth trap must contain the
vgRptrHealthState object. The agent may
optionally include the vgRptrHealthText object in
the varBind list. See the vgRptrHealthState and
vgRptrHealthText objects for descriptions of the
information that is sent.
The agent must throttle the generation of
consecutive vgRptrHealth 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.)"

DESCRIPTION
"A vgRptrResetEvent trap conveys information

This trap is sent on completion of a repeater
reset action. A repeater reset action is defined
as a transition to its initial state as specified
in clause 12 [IEEE Std 802.12] when triggered by
a management command.
The vgRptrResetEvent trap is not sent when the
agent restarts and sends an SNMP coldStart or
warmStart trap. However, it is recommended that
an 802.12 repeater agent send the
vgRptrHealthState object as an optional object
with its coldStart and warmStart trap PDUs.
The vgRptrResetEvent trap must contain the
vgRptrHealthState object. The agent may
optionally include the vgRptrHealthText object in
the varBind list. See the vgRptrHealthState and
vgRptrHealthText objects for descriptions of the
information that is sent.
