Status of This Memo
This document specifies an Internet standards track protocol for the
Internet community, and requests discussion and suggestions for
improvements. Please refer to the current edition of the "Internet
Official Protocol Standards" (STD 1) for the standardization state
and status of this protocol. Distribution of this memo is unlimited.
Abstract
This document defines Management Information Base (MIB) modules for
use with network management protocols in TCP/IP-based internets.
This document describes extensions to the Ethernet-like Interfaces
MIB and Medium Attachment Unit (MAU) MIB modules with a set of
objects for managing Ethernet in the First Mile Copper (EFMCu)
interfaces 10PASS-TS and 2BASE-TL, defined in IEEE Std 802.3ah-2004
(note: IEEE Std 802.3ah-2004 has been integrated into IEEE Std 802.3-
2005). In addition, a set of objects is defined, describing cross-
connect capability of a managed device with multi-layer (stacked)
interfaces, extending the stack management objects in the Interfaces
Group MIB and the Inverted Stack Table MIB modules.

RFC 5066 EFMCu Interfaces MIB November 2007
1. Introduction
New Ethernet-like interfaces have been defined in the Institute of
Electrical and Electronics Engineers (IEEE) Standard 802.3ah-2004
[802.3ah], a.k.a. Ethernet in the First Mile (EFM), which is now a
part of the base IEEE Standard 802.3-2005 [802.3]. In particular,
2BASE-TL and 10PASS-TS physical interfaces (PHYs), defined over
voice-grade copper pairs, have been specified for the long and short
reach, respectively. These interfaces, collectively called EFM
Copper (EFMCu), are based on Single-pair High-speed Digital
Subscriber Line (SHDSL) [G.991.2] and Very High speed Digital
Subscriber Line (VDSL) [G.993.1] technology, supporting optional
Physical Medium Entity (PME) aggregation (a.k.a. multi-pair bonding)
with variable rates.
2BASE-TL PHY is capable of providing at least 2 Mbps over a 2700 m
long single copper pair with a mean Bit Error Rate (BER) of 10^-7
(using 5 dB target noise margin).
10PASS-TS PHY is capable of providing at least 10 Mbps over a 750 m
long single copper pair with a mean BER of 10^-7 (using 6 dB target
noise margin).
This memo defines a Management Information Base (MIB) module for use
with network management protocols in the Internet community to manage
EFMCu interfaces. In addition, a MIB module is defined describing
the cross-connect capability of a stacked interface.
Note that managed objects for Operation, Administration and
Maintenance (OAM) and Ethernet over Passive Optical Networks (EPON)
clauses of IEEE 802.3ah are defined in EFM-COMMON-MIB [RFC4878] and
EFM-EPON-MIB [RFC4837], respectively.
2. The Internet-Standard Management Framework
For a detailed overview of the documents that describe the current
Internet-Standard Management Framework, please refer to section 7 of
RFC 3410 [RFC3410].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. MIB objects are generally
accessed through the Simple Network Management Protocol (SNMP).
Objects in the MIB are defined using the mechanisms defined in the
Structure of Management Information (SMI). This memo specifies MIB
modules that are compliant to the SMIv2, which is described in STD
58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC
2580 [RFC2580].
Beili Standards Track [Page 3]
RFC 5066 EFMCu Interfaces MIB November 2007
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].
3. Relation to Other MIB Modules
This section outlines the relationship of the MIB modules defined in
this document with other MIB modules described in the relevant RFCs.
Specifically, the Interfaces Group MIB (IF-MIB), Ethernet-Like
(EtherLike-MIB), MAU (MAU-MIB), SHDSL (HDSL2-SHDSL-LINE-MIB), and
VDSL (VDSL-LINE-EXT-MCM-MIB) modules are discussed.
3.1. Relation to Interfaces Group MIB Module
2BASE-TL and 10PASS-TS PHYs specified in the EFM-CU-MIB module are
stacked (a.k.a. aggregated or bonded) Ethernet interfaces and as such
are managed using generic interface management objects defined in the
IF-MIB [RFC2863].
The stack management (i.e., actual connection of the sub-layers to
the top-layer interface) is done via the ifStackTable, as defined in
the IF-MIB [RFC2863], and its inverse ifInvStackTable, as defined in
the IF-INVERTED-STACK-MIB [RFC2864].
The new tables ifCapStackTable and its inverse ifInvCapStackTable
defined in the IF-CAP-STACK-MIB module below, extend the stack
management with an ability to describe possible connections or cross-
connect capability, when a flexible cross-connect matrix is present
between the interface layers.
3.1.1. Layering Model
An EFMCu interface can aggregate up to 32 Physical Medium Entity
(PME) sub-layer devices (modems), using the so-called PME Aggregation
Function (PAF).
A generic EFMCu device can have a number of Physical Coding Sublayer
(PCS) ports, each connected to a Media Access Controller (MAC) via a
Medium Independent Interface (MII) at the upper layer, and cross-
connected to a number of underlying PMEs, with a single PCS per PME
relationship. See clause 61.1 of [802.3ah] for more details.
Each PME in the aggregated EFMCu port is represented in the Interface
table (ifTable) as a separate interface with ifType of shdsl(169) for
2BASE-TL or vdsl(97) for 10PASS-TS. The ifType values are defined in
[IANAifType-MIB].
Beili Standards Track [Page 4]
RFC 5066 EFMCu Interfaces MIB November 2007
ifSpeed for each PME SHALL return the actual data bitrate of the
active PME (e.g., for 2BaseTL PMEs it is a multiple of 64 Kbps). A
zero value SHALL be returned when the PME is Initializing or Down.
The ifSpeed of the PCS is the sum of the current operating data rates
of all PMEs in the aggregation group, without the 64/65-octet
encapsulation overhead and PAF overhead, but accounting for the
Inter-Frame Gaps (IFGs).
When using the stated definition of ifSpeed for the PCS, there would
be no frame loss in the following configuration (the test-sets are
configured to generate 100% of back-to-back traffic, i.e., minimal
IFG, at 10 or 100 Mbps, with min and max frame sizes; the EFM
interfaces are aggregated, to achieve the shown speed):
.-------. .--. .---. .-------.

Figure 2: Use of ifTable and ifMauTable for EFMCu ports
The ifStackTable is indexed by the ifIndex values of the aggregated
EFMCu port (PCS) and the PMEs connected to it. ifStackTable allows a
Network Management application to determine which PMEs are connected
to a particular PCS and change connections (if supported by the
application). The ifInvStackTable, being an inverted version of the
ifStackTable, provides an efficient means for a Network Management
application to read a subset of the ifStackTable and thereby
determine which PCS runs on top of a particular PME.
A new table ifCapStackTable, defined in the IF-CAP-STACK-MIB module,
specifies for each higher-layer interface (e.g., PCS port) a list of
lower-layer interfaces (e.g., PMEs), which can possibly be cross-
connected to that higher-layer interface, determined by the cross-
connect capability of the device. This table, modeled after
ifStackTable, is read-only, reflecting current cross-connect
capability of stacked interface, which can be dynamic in some
implementations (e.g., if PMEs are located on a pluggable module and
the module is pulled out). Note that PME availability per PCS,
described by ifCapStackTable, can be constrained by other parameters,
for example, by aggregation capacity of a PCS or by the PME in
question being already connected to another PCS. So, in order to
Beili Standards Track [Page 6]
RFC 5066 EFMCu Interfaces MIB November 2007
ensure that a particular PME can be connected to the PCS, all
respective parameters (e.g., ifCapStackTable, ifStackTable, and
efmCuPAFCapacity) SHALL be inspected.
The ifInvCapStackTable, also defined in the IF-CAP-STACK-MIB module,
describes which higher-layer interfaces (e.g., PCS ports) can
possibly be connected to a particular lower-layer interface (e.g.,
PME), providing an inverted mapping of the ifCapStackTable. While it
contains no additional information beyond that already contained in
the ifCapStackTable, the ifInvCapStackTable has the ifIndex values in
its INDEX clause in the reverse order, i.e., the lower-layer
interface first, and the higher-layer interface second, providing an
efficient means for a Network Management application to read a subset
of the ifCapStackTable and thereby determine which interfaces can be
connected to run on top of a particular interface.
3.1.2. PME Aggregation Function (PAF)
The PME Aggregation Function (PAF) allows a number of PMEs to be
aggregated onto a PCS port, by fragmenting the Ethernet frames,
transmitting the fragments over multiple PMEs, and assembling the
original frames at the remote port. PAF is OPTIONAL, meaning that a
device with a single PME MAY perform fragmentation and re-assembly if
this function is supported by the device. Note however that the
agent is REQUIRED to report on the PAF capability for all EFMCu ports
(2BASE-TL and 10PASS-TS).
The EFM-CU-MIB module allows a Network Management application to
query the PAF capability and enable/disable it if supported. Note
that enabling PAF effectively turns on fragmentation and re-assembly,
even on a single-PME port.
3.1.3. Discovery Operation
The EFMCu ports may optionally support discovery operation, whereby
PMEs, during initialization, exchange information about their
respective aggregation groups (PCS). This information can then be
used to detect copper misconnections or for an automatic assignment
of the local PMEs into aggregation groups instead of a fixed pre-
configuration.
The MIB modules defined in this document allow a Network Management
application to control the EFM Discovery mechanism and query its
results. Note that the Discovery mechanism can work only if PAF is
supported and enabled.
Beili Standards Track [Page 7]
RFC 5066 EFMCu Interfaces MIB November 2007
Two tables are used by the EFM Discovery mechanism: ifStackTable and
ifCapStackTable. The following pseudo-code gives an example of the
Discovery and automatic PME assignment for a generic PAF-enabled
multi-PCS EFMCu device, located at Central Office (CO), using objects
defined in these MIB modules and in the IF-MIB (Note that automatic
PME assignment is only shown here for the purposes of the example.
Fixed PME pre-assignment, manual assignment, or auto-assignment using
an alternative internal algorithm may be chosen by a particular
implementation):
// Go over all PCS ports in the CO device
FOREACH pcs[i] IN CO_device
{ // Perform discovery and auto-assignment only on PAF enabled ports
// with room for more PMEs
IF ( pcs[i].PAFSupported AND pcs[i].NumPMEs < pcs[i].PAFCapacity )
{ // Assign a unique 6-octet local discovery code to the PCS
// e.g., MAC address
dc = pcs[i].DiscoveryCode = MAC[i];
// Go over all disconnected PMEs, which can
// potentially be connected to the PCS
FOREACH pme[j] IN ifCapStackTable[pcs[i]] AND
NOT IN ifStackTable[pcs[i]] // not connected
{ // Try to grab the remote RT_device, by writing the value
// of the local 6-octet discovery code to the remote
// discovery code register (via handshake mechanism).
// This operation is atomic Set-if-Clear action, i.e., it
// would succeed only if the remote discovery register was
// zero. Read the remote discovery code register via Get
// operation to see if the RT_device, attached via the PME
// is indeed marked as being the CO_device peer.
pme[j].RemoteDiscoveryCode = dc; // Set-if-Clear
r = pme[j].RemoteDiscoveryCode; // Get
IF ( r == dc AND pcs[i].NumPMEs < pcs[i].PAFCapacity)
{ // Remote RT_device connected via PME[j] is/was a peer
// for PCS[i] and there is room for another PME in the
// PCS[i] aggregation group (max. PAF capacity is not
// reached yet).
// Connect this PME to the PCS (via ifStackTable,
// ifInvStackTable being inverse of ifStackTable is
// updated automatically, i.e., pcs[i] is auto-added
// to ifInvStackTable[pme[j]])
ADD pme[j] TO ifStackTable[pcs[i]];
pcs[i].NumPMEs = pcs[i].NumPMEs + 1;
// Discover all other disconnected PMEs,
// attached to the same RT_device and connect them to
// the PCS provided there is enough room for more PMEs.
FOREACH pme[k] IN ifCapStackTable[pcs[i]] AND
NOT IN ifStackTable[pcs[i]]
Beili Standards Track [Page 8]
RFC 5066 EFMCu Interfaces MIB November 2007
{ // Get Remote Discovery Code from the PME to see if
// it belongs to a connected RT_device "grabbed" by
// the CO_device.
r = pme[k].RemoteDiscoveryCode;
IF ( r == dc AND pcs[i].NumPMEs < pcs[i].PAFCapacity)
{ // Physically connect the PME to the PCS
// (pcs[i] is auto-added TO ifInvStackTable[pme[k]])
ADD pme[k] TO ifStackTable[pcs[i]];
pcs[i].NumPMEs = pcs[i].NumPMEs + 1;
}
}
}
// At this point we have discovered all local PMEs which
// are physically connected to the same remote RT_device
// and connected them to PCS[i]. Go to the next PCS.
BREAK;
}
}
}
An SNMP Agent for an EFMCu device builds the ifCapStackTable and its
inverse ifInvCapStackTable according to the information contained in
the Clause 45 PME_Available_register (see [802.3ah] 61.1.5.3 and
45.2.3.20).
Adding a PME to the ifStackTable row for a specific PCS involves
actual connection of the PME to the PCS, which can be done by
modifying Clause 45 PME_Aggregate_register (see [802.3ah] 61.1.5.3
and 45.2.3.21).
Note that the PCS port does not have to be operationally 'down' for
the connection to succeed. In fact, a dynamic PME addition (and
removal) MAY be implemented with an available PME being initialized
first (by setting its ifAdminStatus to 'up') and then added to an
operationally 'up' PCS port, by modifying a respective ifStackTable
(and respective ifInvStackTable) entry.
It is RECOMMENDED that a removal of the last operationally 'up' PME
from an operationally 'up' PCS would be rejected by the
implementation, as this action would completely drop the link.
3.1.4. EFMCu Ports Initialization
EFMCu ports being built on top of xDSL technology require a lengthy
initialization or 'training' process, before any data can pass.
During this initialization, both ends of a link (peers) work
cooperatively to achieve the required data rate on a particular
Beili Standards Track [Page 9]
RFC 5066 EFMCu Interfaces MIB November 2007
copper pair. Sometimes, when the copper line is too long or the
noise on the line is too high, that 'training' process may fail to
achieve a specific target rate with required characteristics.
The ifAdminStatus object from the IF-MIB controls the desired state
of a PCS with all the PMEs connected to it or of an individual PME
port. Setting this object to 'up' instructs a particular PCS or PME
to start the initialization process, which may take tens of seconds
for EFMCu ports, especially if PAF is involved. The ifOperStatus
object shows the operational state of an interface (extended by the
ifMauMediaAvailable object from MAU-MIB for PCS and
efmCuPmeOperStatus defined in the EFM-CU-MIB module for PME
interfaces).
A disconnected PME may be initialized by changing the ifAdminState
from 'down' to 'up'. Changing the ifAdminState to 'up' on the PCS
initializes all PMEs connected to that particular PCS. Note that in
case of PAF some interfaces may fail to initialize while others
succeed. The PCS is considered operationally 'up' if at least one
PME aggregated by its PAF is operationally 'up'. When all PMEs
connected to the PCS are 'down', the PCS SHALL be considered
operationally 'lowerLayerDown'. The PCS SHALL be considered
operationally 'notPresent' if it is not connected to any PME. The
PCS/PME interface SHALL remain operationally 'down' during
initialization.
The efmCuPmeOperStatus defined in the EFM-CU-MIB module expands PME's
ifOperStatus value of 'down' to 'downReady', 'downNotReady', and
'init' values, indicating various EFMCu PME-specific states.
3.1.5. Usage of ifTable
Both PME and PCS interfaces of the EFMCu PHY are managed using
interface-specific management objects defined in the EFM-CU-MIB
module and generic interface objects from the ifTable of IF-MIB, with
all management table entries referenced by the interface index
ifIndex.
The following table summarizes EFMCu-specific interpretations for
some of the ifTable objects specified in the mandatory
ifGeneralInformationGroup:

3.2. Relation to SHDSL MIB Module
G.SHDSL.bis modems, similar to PMEs comprising a 2BASE-TL port, are
described in the HDSL2-SHDSL-LINE-MIB module [RFC4319]. Note that
not all attributes of G.SHDSL modems reflected in the HDSL2-SHDSL-
LINE-MIB module have adequate management objects (Clause 30
attributes and Clause 45 registers) in the EFM standard.
Because of these differences and for the purposes of simplicity,
unification of attributes common to both 2BASE-TL and 10PASS-TS PMEs,
and name consistency (e.g., prefixing the 2BASE-TL PME related
objects with 'efmCuPme2B' instead of 'hdsl2shdsl'), it was decided
not to reference HDSL2-SHDSL-LINE-MIB objects, but define all the
relevant objects in the EFM-CU-MIB module.
However, if some functionality not available in the EFM-CU-MIB module
is required and supported by the PME, e.g., performance monitoring,
relevant HDSL2-SHDSL-LINE-MIB groups MAY be included and applied for
PMEs of 2BASE-TL subtype.
Beili Standards Track [Page 11]
RFC 5066 EFMCu Interfaces MIB November 2007
3.3. Relation to VDSL MIB Module
VDSL modems, similar to the PME(s) comprising a 10PASS-TS port, are
described in the VDSL-LINE-EXT-MCM-MIB module [RFC4070]. Note that
not all attributes of VDSL modems reflected in the VDSL-LINE-EXT-MCM-
MIB module have adequate management objects (Clause 30 attributes and
Clause 45 registers) in the EFM standard.
Because of these differences and for the purposes of simplicity,
unification of attributes common to both 2BASE-TL and 10PASS-TS PMEs,
and name consistency, it was decided not to reference VDSL-LINE-EXT-
MCM-MIB objects, but define all the relevant objects in the EFM-CU-
MIB module.
However, if some functionality not available in the EFM-CU-MIB module
is required and supported by the PME, relevant VDSL-LINE-EXT-MCM-MIB
groups MAY be included and applied for PMEs of 10PASS-TS subtype.
3.4. Relation to Ethernet-Like and MAU MIB Modules
The implementation of the EtherLike-MIB [RFC3635] and MAU-MIB
[RFC4836] modules is REQUIRED for EFMCu interfaces.
Two new values of ifMauType (OBJECT-IDENTITIES of dot3MauType) and
corresponding bit definitions of ifMauTypeListBits
(IANAifMauTypeListBits) have been defined in the IANA-MAU-MIB module
[RFC4836] for EFMCu MAUs:
o dot3MauType2BaseTL and b2BaseTL - for 2BASE-TL MAU
o dot3MauType10PassTS and b10PassTS - for 10PASS-TS MAU
Additionally, the IANA-MAU-MIB module defines two new values of
ifMauMediaAvailable, specifically for EFMCu ports: availableReduced
and ready (in textual convention IANAifMauMediaAvailable). Due to
the PME aggregation, the EFMCu interpretation of some possible
ifMauMediaAvailable values differs from other MAUs as follows:
o unknown - the EFMCu interface (PCS with connected PMEs) is
Initializing
o ready - the interface is Down, at least one PME in the aggregation
group (all PMEs connected to the PCS) is ready for handshake
o available - the interface is Up, all PMEs in the aggregation group
are up
Beili Standards Track [Page 12]
RFC 5066 EFMCu Interfaces MIB November 2007
o notAvailable - the interface is Down, all PMEs in the aggregation
group are Down, no handshake tones are detected by any PME
o availableReduced - the interface is Up, a link fault is detected
at the receive direction by one or more PMEs in the aggregation
group, but at least one PME is Up
o pmdLinkFault - a link fault is detected at the receive direction
by all PMEs in the aggregation group
As an EtherLike interface, every EFMCu port (an ifEntry representing
a consolidation of LLC, MAC, and PCS (sub)layers) SHALL return an
ifType of ethernetCsmacd(6). While most of the MAU characteristics
are not applicable to the EFMCu ports (no auto-negotiation, false
carriers, or jabber), they SHALL return an appropriate ifMauType
(dot3MauType2BaseTL or dot3mauType10PassTS) in order to direct the
management software to look in the EFM-CU-MIB module for the desired
information. For example, the information on the particular EFMCu
flavor that an EFMCu port is running is available from
efmCuOperSubType, defined in the EFM-CU-MIB module.
Since EFMCu PMEs are not EtherLike interfaces, they cannot be
instantiated as MAU interface objects.
4. MIB Structure
4.1. EFM Copper MIB Overview
The main management objects defined in the EFM-CU-MIB module are
split into 2 groups:
o efmCuPort - containing objects for configuration, capabilities,
status, and notifications, common to all EFMCu PHYs.
o efmCuPme - containing objects for configuration, capabilities,
status, and notifications of EFMCu PMEs.
The efmCuPme group in turn contains efmCuPme2B and efmCuPme10P
groups, which define PME profiles specific to 2BASE-TL and 10PASS-TS
PMEs, respectively, as well as PME-specific status information.
4.2. Interface Stack Capability MIB Overview
The IF-CAP-STACK-MIB module contains 2 tables:
o ifCapStackTable - containing objects that define possible
relationships among the sub-layers of an interface with flexible
cross-connect (cross-connect capability).
Beili Standards Track [Page 13]
RFC 5066 EFMCu Interfaces MIB November 2007
o ifInvCapStackTable - an inverse of the ifCapstackTable.
4.3. PME Profiles
Since a managed node can have a large number of EFMCu PHYs,
provisioning every parameter on every EFMCu PHY may become
burdensome. Moreover, most PMEs are provisioned identically with the
same set of parameters. To simplify the provisioning process, the
EFM-CU-MIB module makes use of configuration profiles, similar to the
HDSL2-SHDSL-LINE-MIB and VDSL-LINE-EXT-MCM-MIB modules. A profile is
a set of parameters, used either for configuration or representation
of a PME. The same profile can be shared by multiple PME ports using
the same configuration.
The PME profiles are defined in the efmCuPme2BProfileTable and
efmCuPme10PProfileTable for 2BASE-TL and 10PASS-TS PMEs,
respectively. There are 12 predefined standard profiles for 2BASE-TL
and 22 standard profiles for 10PASS-TS, defined in 802.3ah and
dedicated for rapid provisioning of EFMCu PHYs in most scenarios. In
addition, the EFM-CU-MIB defines two additional predefined profiles
for "best-effort" provisioning of 2BASE-TL PMEs. An ability to
define new configuration profiles is also provided to allow for EFMCu
deployment tailored to specific copper environments and spectral
regulations.
A specific configuration or administrative profile is assigned to a
specific PME via the efmCuPmeAdminProfile object. If
efmCuPmeAdminProfile is zero, then the efmCuAdminProfile object of
the PCS port connected to the PME determines the configuration
profile (or a list of possible profiles) for that PME. This
mechanism allows specifying a common profile for all PMEs connected
to the PCS port, with an ability to change individual PME profiles by
setting efmCuPmeAdminProfile object, which overwrites the profile set
by efmCuAdminProfile.
A current operating PME profile is pointed to by the
efmCuPmeOperProfile object. Note that this profile entry can be
created automatically to reflect achieved parameters in adaptive (not
fixed) initialization.
4.4. Mapping of IEEE 802.3ah Managed Objects
This section contains the mapping between relevant managed objects
(attributes) defined in [802.3ah] Clause 30, and managed objects
defined in this document and in associated MIB modules, i.e., the IF-
MIB [RFC2863].
Beili Standards Track [Page 14]
RFC 5066 EFMCu Interfaces MIB November 2007
Note that the majority of the objects defined in the EFM-CU-MIB
module do not have direct counterparts in Clause 30 and instead refer
to Clause 45 registers.

DESCRIPTION
"This table, modeled after ifStackTable from IF-MIB,
contains information on the possible 'on-top-of'
relationships between the multiple sub-layers of network
interfaces (as opposed to actual relationships described in
ifStackTable). In particular, it contains information on
which sub-layers MAY possibly run 'on top of' which other
sub-layers, as determined by cross-connect capability of the
device, where each sub-layer corresponds to a conceptual row
in the ifTable. For example, when the sub-layer with ifIndex
value x can be connected to run on top of the sub-layer with
ifIndex value y, then this table contains:
ifCapStackStatus.x.y=true
The ifCapStackStatus.x.y row does not exist if it is
impossible to connect between the sub-layers x and y.
Note that for most stacked interfaces (e.g., 2BASE-TL)
there's always at least one higher-level interface (e.g., PCS
port) for each lower-level interface (e.g., PME) and at
least one lower-level interface for each higher-level
interface, that is, there is at least a single row with a
'true' status for any such existing value of x or y.
This table is read-only as it describes device capabilities."

false(2) - the sub-layer interfaces cannot be
connected temporarily due to
unavailability of the interface(s), e.g.,
one of the interfaces is located on an
absent pluggable module.
Note that lower-layer interface availability per higher-layer,
indicated by the value of 'true', can be constrained by
other parameters, for example, by the aggregation capacity of
a higher-layer interface or by the lower-layer interface in
question being already connected to another higher-layer
interface. In order to ensure that a particular sub-layer can
be connected to another sub-layer, all respective objects
(e.g., ifCapStackTable, ifStackTable, and efmCuPAFCapacity for

"This notification indicates that the EFMCu port's data rate

from low to normal. This notification is not applicable to
the -R subtypes.
It is RECOMMENDED that a small debouncing period of 2.5 sec,
between the detection of the condition and the notification,
is implemented to prevent simultaneous LinkUp/LinkDown and
efmCuLowRateCrossing notifications to be sent.
The adaptive nature of the EFMCu technology allows the port to
adapt itself to the changes in the copper environment, e.g.,
an impulse noise, alien crosstalk, or a micro-interruption may
temporarily drop one or more PMEs in the aggregation group,
causing a rate degradation of the aggregated EFMCu link.
The dropped PMEs would then try to re-initialize, possibly at
a lower rate than before, adjusting the rate to provide
required target SNR margin.

efmCuAdminProfile.
A list consisting of more than one index allows each PME

read this object and an attempt to change this object MUST be
rejected in this case.
Note that the current operational profile value is available
via the efmCuPmeOperProfile object.
Any modification of this object MUST be performed when the

efmCuPmeAdminProfile, with the desired SNR margin specified by
efmCuTargetSnrMgn.
In case of PAF, this object represents a sum of individual PME
data rates, modified to compensate for fragmentation and
64/65-octet encapsulation overhead (e.g., target data rate of
10 Mbps SHALL allow lossless transmission of a full-duplex
10 Mbps Ethernet frame stream with minimal inter-frame gap).
The value is limited above by 100 Mbps as this is the max
burst rate across MII for EFMCu ports.
The value between 1 and 100000 indicates that the total data
rate (ifSpeed) of the EFMCu port after initialization SHALL be
equal to the target data rate or less, if the target data rate
cannot be achieved under spectral restrictions specified by
efmCuAdminProfile/efmCuPmeAdminProfile and with the desired
SNR margin. In case the copper environment allows a higher
total data rate to be achieved than that specified by the
target, the excess capability SHALL be either converted to
additional SNR margin or reclaimed by minimizing transmit
power as controlled by efmCuAdaptiveSpectra.
The value of 999999 means that the target data rate is not
fixed and SHALL be set to the maximum attainable rate during
initialization (Best Effort), under specified spectral
restrictions and with the desired SNR margin.
This object is read-write for the -O subtype EFMCu ports
(2BaseTL-O/10PassTS-O) and not available for the -R subtypes.
Changing of the Target Data Rate MUST be performed when the
link is Down. Attempts to change this object MUST be rejected

link is Up or Initializing.
Note that the current Data Rate of the EFMCu port is

7. Security Considerations
There is a number of managed objects defined in the EFM-CU-MIB module
that have a MAX-ACCESS clause of read-write or read-create. Most
objects are writeable only when the link is Down. Writing to these
objects can have potentially disruptive effects on network operation,
for example:
o Changing of efmCuPmeAdminSubType may lead to a potential locking
of the link, as peer PMEs of the same subtype cannot exchange
handshake messages.
o Changing of efmCuPAFAdminState to enabled may lead to a potential
locking of the link, if the peer PHY does not support PAF.
o Changing of efmCuPAFDiscoveryCode, before the discovery operation,
may lead to a wrongful discovery, for example, when two -O ports
are connected to the same multi-PME -R port and both -O ports have
the same Discovery register value.
Beili Standards Track [Page 84]
RFC 5066 EFMCu Interfaces MIB November 2007
o Changing PCS or PME configuration parameters (e.g., profile of a
PCS or PME via efmCuAdminProfile or efmCuPmeAdminProfile) may lead
to anything from link quality and rate degradation to a complete
link initialization failure, as ability of an EFMCu port to
support a particular configuration depends on the copper
environment.
o Activation of a PME can cause a severe degradation of service for
another EFMCu PHY, whose PME(s) may be affected by the cross-talk
from the newly activated PME.
o Removal of a PME from an operationally 'up' EFMCu port,
aggregating several PMEs, may cause port's rate degradation.
The user of the EFM-CU-MIB module must therefore be aware that
support for SET operations in a non-secure environment without proper
protection can have a negative effect on network operations.
The readable objects in the EFM-CU-MIB module (i.e., those with MAX-
ACCESS other than not-accessible) may be considered sensitive in some
environments since, collectively, they provide information about the
performance of network interfaces and can reveal some aspects of
their configuration. In particular, since EFMCu can be carried over
Unshielded Twisted Pair (UTP) voice-grade copper in a bundle with
other pairs belonging to another operator/customer, it is
theoretically possible to eavesdrop to an EFMCu transmission simply
by "listening" to a cross-talk from the EFMCu pairs, especially if
the parameters of the EFMCu link in question are known.
In such environments, it is important to control also GET and NOTIFY
access to these objects and possibly even to encrypt their values
when sending them over the network via SNMP.
SNMP versions prior to SNMPv3 did not include adequate security.
Even if the network itself is secure (for example by using IPsec),
even then, there is no control as to who on the secure network is
allowed to access and GET/SET (read/change/create/delete) the objects
in these MIB modules.
It is RECOMMENDED that implementers consider the security features as
provided by the SNMPv3 framework (see [RFC3410], section 8),
including full support for the SNMPv3 cryptographic mechanisms (for
authentication and privacy).
Further, deployment of SNMP versions prior to SNMPv3 is NOT
RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to
enable cryptographic security. It is then a customer/operator
responsibility to ensure that the SNMP entity giving access to an
Beili Standards Track [Page 85]
RFC 5066 EFMCu Interfaces MIB November 2007
instance of these MIB modules is properly configured to give access
to the objects only to those principals (users) that have legitimate
rights to indeed GET or SET (change/create/delete) them.
8. IANA Considerations
Object identifiers for the efmCuMIB MODULE-IDENTITY and ifCapStackMIB
MODULE-IDENTITY have been allocated by IANA in the MIB-2 sub-tree.
