Internet-Draft G.Bond MIB May 2009
1. Introduction
The xDSL Multi-Pair Bonding, allows a service provider to provide
high bandwidth services to business and residential customers over
multiple xDSL lines, with greater speed and resiliency, than the
service over a single xDSL line, bridging the gap between xDSL and
fiber-based transport.
There are three xDSL Multi-Pair Bonding schemes, also known under
collective name G.Bond:
o The ATM-Based Multi-Pair Bonding, specified in ITU-T G.998.1
recommendation [G.998.1], which defines a method for bonding (or
aggregating) of multiple xDSL lines (or individual bearer channels
in multiple xDSL lines) into a single bi-directional logical link
carrying an ATM stream. This specification can be viewed as an
evolution of the legacy Inverse Multiplexing over ATM (IMA)
technology [af-phy-0086], applied to xDSL with variable rates on
each line/bearer channel.
o The Ethernet-Based Multi-Pair Bonding, specified in ITU-T G.998.2
recommendation [G.998.2], which defines a method for bonding (or
aggregating) of multiple xDSL lines (or individual bearer channels
in multiple xDSL lines) into a single bi-directional logical link
carrying an Ethernet stream. This specification can be viewed as
IEEE 802.3-2005 [802.3] Clause 61 Physical Medium Entity (PME)
Aggregation, generalized to work over any xDSL technology.
(2Base-TL and 10Pass-TS interfaces defined by IEEE use G.SHDSL and
VDSL technology respectively).
o The Multi-pair bonding using time-division inverse multiplexing
(TDIM), specified in ITU-T G.998.3 recommendation [G.998.3], which
defines a method for bonding (or aggregating) of multiple xDSL
lines into a single bi-directional logical link carrying a mix of
various traffic streams (e.g., Ethernet, ATM, TDM).
Architecturally all three bonding schemes define a new "bonded"
Transport Protocol Specific - Transmission Convergence (TPS-TC) sub-
layer, stacked above multiple ATM-TC, Ethernet/PTM-TC or STM-TC
(clear channel) sub-layers for the ATM, Ethernet or TDIM bonding
respectively. Each underlying TPS-TC sub-layer represents a protocol
specific gamma-interface to an xDSL line or an individual bearer
channel of an xDSL line. Bonding of multiple bearer channels in the
same xDSL line is not allowed.
All schemes allow bonding of up to 32 individual line/channel sub-
layers with variable rates, providing common functionality for the
configuration, initialization, operation and monitoring of the bonded

link.
This document defines a MIB module common to all 3 schemes.
Additional managed objects, specific to each bonding technology, are
defined in GBOND-ATM-MIB [I-D.ietf-adslmib-gbond-atm-mib], GBOND-ETH-
MIB [I-D.ietf-adslmib-gbond-eth-mib] and GBOND-TDIM-MIB
[I-D.ietf-adslmib-gbond-tdim-mib] modules.
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 document specifies a
MIB module that is compliant to the SMIv2, which is described in STD
58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC
2580 [RFC2580].
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. The DSL Forum Management Framework for xDSL Bonding
This document makes use of the DSL Forum technical report Management
Framework for xDSL Bonding [TR-159], defining a management model and
a hierarchy of management objects for the bonded xDSL interfaces.
4. Relationship 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 following MIB modules are discussed: Interfaces
Group MIB (IF-MIB), Inverse Stack Table MIB (IF-INVERTED-STACK-MIB)
Interface Stack Capability MIB (IF-CAP-STACK-MIB), G.Bond scheme
specific modules: G.Bond/ATM (GBOND-ATM-MIB), G.Bond/Ethernet (GBOND-
ETH-MIB) and G.Bond/TDIM (GBOND-TDIM-MIB), and DSL specific MIB
modules: ADSL (ADSL-LINE-EXT-MIB), ADSL2 (ADSL2-LINE-MIB), SHDSL
(HDSL2-SHDSL-LINE-MIB), VDSL (VDSL-LINE-MIB) and VDSL2 (VDSL2-LINE-
MIB).

Internet-Draft G.Bond MIB May 2009
4.1. Relationship to Interfaces Group MIB module
A bonded xDSL port is a stacked (a.k.a. aggregated or bonded)
interface and as such is 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 ifCapStackTable and its inverse ifInvCapStackTable defined in the
IF-CAP-STACK-MIB [RFC5066], 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.
4.1.1. Layering Model
A G.Bond interface can aggregate up to 32 channel sub-layers, with
each channel representing an xDSL line or an xDSL bearer channel.
For the purpose of brevity we will refer to the bonded interface as
Generic Bonded Sub-layer (GBS) and to the channel sub-layer as
Bonding Channel Entity (BCE).
A generic G.Bond device can have a number of GBS ports, each
connected to a particular upper layer (e.g., Media Access Control
(MAC) interface for G.998.2 scheme), while simultaneously cross-
connected to a number of underlying BCEs, with a single GBS per BCE
relationship.
A GBS port is represented in the Interface table (ifTable) as a
separate interface with an ifType of g9981, g9982 or g9983 for a
particular bonding scheme.
Each BCE in the aggregated GBS port is represented in the ifTable as
a separate interface with an ifType relevant to a particular xDSL
technology, e.g., shdsl(169) or vdsl(97). The ifType values are
defined in [IANAifType-MIB].
Beili & Morgenstern Expires November 21, 2009 [Page 5]
Internet-Draft G.Bond MIB May 2009
The following figure shows the layering diagram and corresponding use
of ifTable for the bonded xDSL interfaces:

BCE - Bonding Channel Entity
GBS - Generic Bonded Sub-layer
PMD - Physical Medium Dependent

PMS-TC - Physical Media Specific - Transmission Convergence
Figure 1: Use of ifTable for bonded xDSL interfaces
The ifStackTable is indexed by the ifIndex values of the aggregated
G.Bond port (GBS) and the BCEs connected to it. ifStackTable allows a
Network Management application to determine which BCEs are connected
to a particular GBS 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 GBS runs on top of a particular BCE.
The ifCapStackTable defined in the IF-CAP-STACK-MIB module, specifies
for each higher-layer interface (e.g., GBS port) a list of lower-
layer interfaces (e.g., BCEs), 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 a stacked
interface, which can be dynamic in some implementations (e.g., if
xDSL lines are located on a pluggable module and the module is pulled
out). Note that BCE availability per GBS, described by
ifCapStackTable, can be constrained by other parameters, for example
by aggregation capacity of a GBS or by the BCE in question being
already connected to another GBS. So, in order to ensure that a
particular BCE can be connected to the GBS, all respective parameters
(e.g., ifCapStackTable, ifStackTable and gBondCapacity) SHALL be
inspected.
The ifInvCapStackTable, also defined in the IF-CAP-STACK-MIB module,
Beili & Morgenstern Expires November 21, 2009 [Page 6]
Internet-Draft G.Bond MIB May 2009
describes which higher-layer interfaces (e.g., GBS ports) can
possibly be connected to a particular lower-layer interface (e.g.,
BCE), providing inverted mapping of 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.
4.1.2. xDSL Bonding
The G.998.x Bonding allows a number of BCEs to be aggregated onto a
single logical GBS port, by splitting the incoming traffic into
multiple streams, transmitting each stream over a specific BCE and
combining the streams at the remote GBS port, preserving the original
traffic order.
Big Ethernet frames MAY be fragmented before the transmission and
reassembled at the remote end to minimize transportation delay.
The Bonding is OPTIONAL, meaning that a device with a single BCE MAY
perform fragmentation and re-assembly if this function is supported
by the device. The agent is REQUIRED to report on the Bonding
capability for all types of G.Bond ports (ATM, Ethernet and TDIM).
The GBOND-MIB module allows a Network Management application to query
Bonding capability and enable/disable it if supported. Note that
enabling Bonding effectively turns on fragmentation and re-assembly,
even on a single-BCE port.
4.1.3. Discovery Operation
The G.Bond ports may optionally support discovery operation, whereby
BCEs, during initialization, exchange information about their
respective aggregation groups (GBS), via xDSL handshake protocol.
This information can then be used to detect copper misconnections or
for an automatic assignment of the local BCEs into aggregation groups
instead of a fixed pre-configuration.
The MIB module defined in this document allow a Network Management
application to control G.Bond Discovery mechanism and query its
results. Note that the Discovery mechanism can work only if Bonding
is supported and enabled.
Two tables are used by the G.Bond Discovery mechanism: ifStackTable
and ifCapStackTable. The following pseudo-code gives an example of
Beili & Morgenstern Expires November 21, 2009 [Page 7]
Internet-Draft G.Bond MIB May 2009
the Discovery and automatic BCE assignment for a generic multi-GBS
G.Bond device, located at Central Office (CO), using objects defined
in this MIB module, IF-CAP-STACK-MIB and IF-MIB modules [Note that
automatic BCE assignment is only shown here for the purposes of the
example. Fixed BCE pre-assignment, manual assignment or auto-
assignment using an alternative internal algorithm may be chosen by a
particular implementation]:
// Go over all GBS ports in the CO device
FOREACH gbs[i] IN CO_device
{ // Perform discovery and auto-assignment on GBS ports
// with room for more Channels
IF ( gbs[i].NumBCEs < gbs[i].BondCapacity )
{ // Assign a unique 6-octets local discovery code to the GBS
// e.g., MAC address
dc = gbs[i].DiscoveryCode = MAC[i];
// Go over all disconnected Channels, which can
// pottentially be connected to the GBS
FOREACH bce[j] IN ifCapStackTable[gbs[i]] AND
NOT IN ifStackTable[gbs[i]] // not connected
{ // Try to grab the remote RT_device, by writing the value
// of the local 6 Byte 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 BCE
// is indeed marked as being the CO_device peer.
bce[j].RemoteDiscoveryCode = dc; // Set-if-Clear
r = bce[j].RemoteDiscoveryCode; // Get
IF ( r == dc AND gbs[i].NumBCEs < gbs[i].BondCapacity)
{ // Remote RT_device connected via BCE[j] is/was a peer
// for GBS[i] and there room for another BCE in the
// GBS[i] aggregation group (max. Bonding capacity is
// not reached yet).
// Connect this BCE to the GBS (via ifStackTable,
// ifInvStackTable being inverse of ifStackTable is
// updated automatically, i.e., gbs[i] is auto-added
// to ifInvStackTable[bce[j]])
ADD bce[j] TO ifStackTable[gbs[i]];
gbs[i].NumBCEs = gbs[i].NumBCEs + 1;
// Discover all other disconnected BCEs,
// attached to the same RT_device and connect them to
// the GBS provided there is enough room for more BCEs.
FOREACH bce[k] IN ifCapStackTable[gbs[i]] and
NOT IN ifStackTable[gbs[i]]
{ // Get Remote Discovery Code from the BCE to see if
// it belongs to a connected RT_device "grabbed" by
Beili & Morgenstern Expires November 21, 2009 [Page 8]
Internet-Draft G.Bond MIB May 2009
// the CO_device.
r = bce[k].RemoteDiscoveryCode;
IF ( r == dc AND gbs[i].NumBCEs < gbs[i].BondCapacity)
{ // Physically connect the BCE to the GBS
// (gbs[i] is auto-added TO ifInvStackTable[bce[k]])
ADD bce[k] TO ifStackTable[gbs[i]];
gbs[i].NumBCEs = gbs[i].NumBCEs + 1;
}
}
}
// At this point we have discovered all local BCEs which
// are physically connected to the same remote RT_device
// and connected them to GBS[i]. Go to the next GBS.
BREAK;
}
}
}
An SNMP Agent for a G.Bond device builds ifCapStackTable and its
inverse ifInvCapStackTable on device initialiation, according to the
cross-connect capabilities of the device.
Adding a BCE to the ifStackTable row for a specific GBS, involves
actual connection of the BCE to the GBS.
Note that GBS port does not have to be operationally 'down' for the
connection to succeed. In fact, a dynamic BCE addition (and removal)
MAY be implemented with an available BCE being initialized first (by
setting its ifAdminStatus to 'up') and then added to an operationally
'up' GBS port, by modifying a respective ifStackTable (and respective
ifInvStackTable) entry.
It is RECOMMENDED that a removal of the last operationally 'up' BCE
from an operationally 'up' GBS would be rejected by the
implementation, as this action would completely drop the link.
In addition to the standard handshake-based discovery described
above, [G.998.2] defines an optional frame-based discovery and pair
management. These frame-based methods are discussed in
[I-D.ietf-adslmib-gbond-eth-mib].
4.1.4. G.Bond ports initialization
G.Bond 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 required data rate on a particular copper
pair. Sometimes, when the copper line is too long or the noise on
Beili & Morgenstern Expires November 21, 2009 [Page 9]
Internet-Draft G.Bond MIB May 2009
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 GBS with all the BCEs connected to it or of an individual BCE
port. Setting this object to 'up' instructs a particular GBS or a
BCE to start initialization process, which may take tens of seconds
for G.Bond ports. The ifOperStatus object shows the operational
state of an interface (extended by ifMauMediaAvailable object from
MAU-MIB [RFC4836] for GBS and *Status object from a relevant line MIB
for BCE interfaces).
A disconnected BCE may be initialized by changing the ifAdminState
from 'down' to 'up'. Changing the ifAdminState to 'up' on the GBS
initializes all BCEs connected to that particular GBS. Note that in
case of bonding some interfaces may fail to initialize while others
succeed. The GBS is considered operationally 'up' if at least one
bonded BCE is operationally 'up'. When all BCEs connected to the GBS
are 'down' the GBS SHALL be considered operationally
'lowerLayerDown'. The GBS SHALL be considered operationally
'notPresent' if it is not connected to any BCE. The GBS/BCE
interface SHALL remain operationally 'down' during initialization.
4.1.5. Usage of ifTable
Both BCE and GBS interfaces are managed using interface specific
management objects defined in the GBOND-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 G.Bond specific interpretations for
some of the ifTable objects specified by the mandatory
ifGeneralInformationGroup:
+---------------+---------------------------------------------------+
| IF-MIB object | G.Bond interpretation |
+---------------+---------------------------------------------------+
| ifIndex | Interface index. Note that each BCE and each GBS |
| | in the G.Bond PHY MUST have a unique index, as |

4.2. Relationship to xDSL MIB modules
Each xDSL technology is described in a relevant xDSL line MIB module:
e.g., HDSL2-SHDSL-LINE-MIB [RFC4319] for G.SHDSL, ADSL-LINE-EXT-MIB
[RFC3440] for ADSL, ADSL2-LINE-MIB [RFC4706] for ADSL2, VDSL-LINE-MIB
[RFC3728] for VDSL or VDSL2-LINE-MIB [I-D.ietf-adslmib-vdsl2-mib] for
VDSL2.
These MIBs are used to manage individual xDSL lines/channels (BCEs).
5. MIB Structure
5.1. Overview
The main management objects defined in the GBOND-MIB module are split
into 2 groups:
o gBondPort - containing objects for configuration, capabilities,
status and notifications, common to all G.Bond ports (GBS).
o gBondBce - containing a single common object for configuration of
the remote discovery code per BCE. Note that the rest of the
objects for BCE configuration, capabilities, status and
notifications, is located in relevant xDSL line MIB modules as
well as in the bonding scheme specific MIB modules.

Internet-Draft G.Bond MIB May 2009
5.2. Performance Monitoring
The OPTIONAL performance monitoring counters, thresholds and history
buckets (interval-counters) defined in [TR-159] are implemented using
the textual conventions defined in the HC-PerfHist-TC-MIB [RFC3705].
The HC-PerfHist-TC-MIB defines 64-bit versions of the textual
conventions found in PerfHist-TC-MIB [RFC3593].
The agent SHOULD align the beginning of each interval to a fifteen
minute boundary of a wall clock. Likewise, the beginning of each one
day intervals SHOULD be aligned with the start of a day.
Counters are not reset when a GBS is reinitialized, only when the
agent is reset or reinitialized (or under specific request outside
the scope of this MIB module).
5.3. Mapping of DSL Forum TR-159 Managed Objects
This section contains the mapping between relevant managed objects
(attributes) defined in [TR-159] and managed objects defined in this

DESCRIPTION
"This notification indicates that the G.Bond port' upstream
data rate has reached/dropped below or exceeded the low
upstream rate threshold, specified by gBondThreshLowUpRate.
This notification MAY be sent for the -O subtype ports
while the port is up, on the crossing event in both
directions: from normal (rate is above the threshold) to low
(rate equals the threshold or below it) and 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 notification,
is implemented to prevent simultaneous LinkUp/LinkDown and
gBondLowUpRateCrossing notifications to be sent.
The adaptive nature of the G.Bond 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 BCEs in
the aggregation group, causing a rate degradation of the
aggregated G.Bond link. The dropped BCEs would then try to
re-initialize, possibly at a lower rate than before, adjusting
the rate to provide required target SNR margin.
Generation of this notification is controlled by the
gBondLowRateCrossingEnable object.

DESCRIPTION
"A desired G.Bond port Data Rate in the upstream direction,
in Kbps, to be achieved during initialization, under
restrictions placed upon the member BCEs by their respective
configuration settings.
This object represents a sum of individual BCE upstream data
rates, modified to compensate for fragmentation and
encapsulation overhead (e.g., for an Ethernet service, the
target data rate of 10Mbps SHALL allow lossless transmission
of full-duplex 10Mbps Ethernet frame stream with minimal
inter-frame gap).
Note that the target upstream data rate may not be achieved
during initialization (e.g., due to unavailability of required
BCEs) or the initial bandwidth could deteriorate, so that the
actual upstream data rate (gBondUpDataRate) could be less
than gBondTargetUpDataRate.
The value is limited above by 10 Gbps, to accomodate very
high speed bonded xDSL interfaces (e.g. 32 x 100Mbps).
The value between 1 and 10000000 indicates that the total
upstream data rate of the G.Bond port after initialization
SHALL be equal to the target data rate or less, if the target
upstream data rate cannot be achieved under the restrictions
configured for BCEs. In case the copper environment allows to
achieve higher upstream data rate than that specified by this
object, the excess capability SHALL be either converted to
additional SNR margin or reclaimed by minimizing transmit
power.
The value of 0 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 desired SNR Margin per BCE.

7. Security Considerations
There is a number of managed objects defined in the GBOND-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 gBondAdminScheme MAY lead to a potential locking of
the link, if the peer device does not support desired bonding
scheme.
o Changing of gBondDiscoveryCode, before the discovery operation,
MAY lead to a wrongful discovery, for example when two CO ports
are connected to the same multi-channel RT port, while both CO
ports have the same Discovery register value.
o Changing GBS configuration parameters (e.g., profile of a GBS via
gBondAdminProfile) MAY lead to anything from link quality and rate
degradation to a complete link initialization failure, as ability
of an G.Bond port to support a particular configuration depends on
the copper environment.
o Activation of a specific line/channel MAY cause a severe
degradation of service for another G.Bond port, whose channel(s)
MAY be affected by the cross-talk from the newly activated
channel.
o Removal of a channel from an operationally 'up' G.Bond port,
aggregating several channels, MAY cause port's rate degradation
The user of the GBOND-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 GBOND-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 a bonded xDSL port can be
comprised of multiple Unshielded Twisted Pair (UTP) voice grade
copper, located in the same bundle with other pairs belonging to
another operator/customer, it is theoretically possible to evasdrop
to a G.Bond transmission, simply by "listening" to a cross-talk from
the bonded pairs, especially if the parameters of the G.Bond link in
question are known.
In such environments it is important to control also GET and NOTIFY
Beili & Morgenstern Expires November 21, 2009 [Page 60]
Internet-Draft G.Bond MIB May 2009
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 this MIB module.
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
instance of this MIB module 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
Three new values of IANAifType: g9981, g9982 and g9982 SHALL be
defined by the IANA [1] in the IANAifType-MIB module
[IANAifType-MIB], before this document is published as an RFC.
Additionally, an object identifier for gBondMIB MODULE-IDENTITY SHALL
be allocated by IANA in the MIB-2 transmission sub-tree, before this
document is published.
