1. Introduction
Ethernet-based xDSL Multi-Pair Bonding, a.k.a. G.Bond/Ethernet, is
specified in ITU-T Recommendation G.998.2 [G.998.2], which defines a
method for bonding (or aggregating) multiple xDSL lines (or
individual bearer channels in multiple xDSL lines) into a single
bidirectional logical link carrying Ethernet traffic.
The MIB module defined in this document provides G.Bond/
Ethernet-specific objects for the management of G.998.2 bonded
interfaces, extending the common bonding objects specified in the
GBOND-MIB module [RFC6765].
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 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", "NOT RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in
BCP 14, RFC 2119 [RFC2119].
3. The Broadband Forum Management Framework for xDSL Bonding
This document makes use of the Broadband 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: the Interfaces
Group MIB (IF-MIB), G.Bond MIB (GBOND-MIB), and Ethernet in the First
Mile (EFM) Copper MIB (EFM-CU-MIB).
4.1. Relationship to Interfaces Group MIB Module
A G.Bond/Ethernet port is a private case of a bonded multi-pair xDSL
interface and as such is managed using generic interface management
objects defined in the IF-MIB [RFC2863]. In particular, an interface
index (ifIndex) is used to index instances of G.Bond/Ethernet ports,
as well as xDSL lines/channels, in a managed system.
4.2. Relationship to G.Bond MIB Module
The GBOND-MIB module [RFC6765] defines management objects common for
all bonded multi-pair xDSL interfaces. In particular, it describes
the bonding management, bonded port and channel configuration,
handshake-based discovery, initialization sequence, etc.
Both the GBOND-MIB [RFC6765] and G9982-MIB (this document) modules
are REQUIRED to manage a G.Bond/Ethernet port.
4.2.1. BACP-Based Discovery
All G.998 protocols share a remote Bonding Channel Entity (BCE)
discovery, using the [G.994.1] handshake (G.hs). The GBOND-MIB
module provides an example of an automatic BCE connection to the
corresponding Generic Bonding Sub-layer (GBS) ports of a generic
G.998 multi-port Central Office (CO) device, using G.hs-based BCE
discovery. Amendment 2 to the ITU-T G.998.2 specification
[G.998.2-Amd2] provides an alternative optional Bonding Aggregation
Control Protocol (BACP) for in-service discovery, aggregation, and
pair management.
The following pseudocode gives the same example of the discovery and
automatic BCE assignment for a multi-GBS G.Bond/Eth CO device, using
BACP objects defined in this MIB module, as well as the
IF-CAP-STACK-MIB [RFC5066] 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 )
{ IF ( gbs[i].g9982OperCp == cpBACP )
{ // Using BACP
// Get Eligible Group ID and Remote Group ID
// from a connected BCE (during BACP
// initialization, each BCE is connected to its own GBS)
gid = ifStackTable[gbs[i]].bce[0].g9982BceEligibleGroupID;
rgid =
ifStackTable[gbs[i]].bce[0].g9982BcePeerEligibleGroupID;
// Go over all disconnected channels, which can
// potentially be connected to the GBS
FOREACH bce[j] IN ifCapStackTable[gbs[i]] AND
NOT IN ifStackTable[gbs[i]] // not connected
{ // Read the Remote Group ID for the selected BCE
// and compare it with the Remote Group ID of the connected
// BCE.
r = bce[j].g9982BcePeerEligibleGroupID;
IF ( r == rgid AND gbs[i].NumBCEs < gbs[i].BondCapacity )
{ // The Remote Terminal device (RT) connected via BCE[j] is
// a peer for GBS[i], and there is room for another BCE in
// the GBS[i] aggregation group (max. Bonding capacity is
// not reached yet).
// Connect this BCE to the GBS (via the ifStackTable; the
// ifInvStackTable, which is the inverse of the
// 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;
}
}
// At this point, we have discovered all local BCEs that
// are physically connected to the same RT
// and have connected them to GBS[i]. Go to the next GBS.
BREAK;
}
ELSE
{ // Use default G.hs discovery protocol.
...
}
}
}
An SNMP agent for a G.Bond device builds the ifCapStackTable and its
inverse -- the ifInvCapStackTable -- on device initialization,
according to the cross-connect capabilities of the device. When BACP
is used, the g9982BceConfEligibleGroupID object identifying bonding
eligibility MUST be automatically updated whenever the
ifCapStackTable/ifInvCapStackTable are changed.
4.3. Relationship to EFM Copper MIB Module
The EFM-CU-MIB module [RFC5066] defines objects for managing Ethernet
in the First Mile Copper (EFMCu) interfaces 10PASS-TS and 2BASE-TL,
as defined in IEEE Std 802.3-2005 [802.3]. These interfaces are
based on Single-pair High-speed DSL (SHDSL) [G.991.2] and Very high
speed DSL (VDSL) [G.993.1] technology, respectively, and can be
optionally aggregated (bonded).
The ITU-T G.998.2 specification extends the IEEE 802.3 Clause 61
bonding to work over any xDSL technology, providing the ability to
bond individual channels as well as physical lines. It also allows
the use of alternative High-level Data Link Control (HDLC)
encapsulation instead of the default 64/65-octet encapsulation and
adds a new optional Bonding Aggregation Control Protocol (BACP) for
in-service discovery, aggregation, and pair management instead of the
default G.hs-based bonding protocol, which cannot be used in-service,
while the link is 'up'.
EFM-CU-MIB can be used to manage all aspects of the EFMCu physical
interfaces (PHYs), including complete (within the scope of the 802.3
standard) management of the SHDSL/VDSL lines. The GBOND-MIB and
G9982-MIB modules, on the other hand, provide management objects only
for the bonding part, leaving the management of the individual xDSL
interfaces (lines/channels) to the respective xDSL-LINE-MIB modules.
Therefore, an IEEE 802.3 2BASE-TL/10PASS-TS interface can be managed
by either combination of the following MIB modules:
IF-MIB + IF-CAP-STACK-MIB + EtherLike-MIB + MAU-MIB + EFM-CU-MIB
IF-MIB + IF-CAP-STACK-MIB + GBOND-MIB + G9982-MIB +
HDSL2-SHDSL-LINE-MIB/VDSL-LINE-MIB
(The EtherLike-MIB, HDSL2-SHDSL-LINE-MIB, and VDSL-LINE-MIB modules
are found in [RFC3635], [RFC4319], and [RFC3728], respectively.)
Note also that while EFM-CU-MIB relies on the ifMauMediaAvailable
object from MAU-MIB [RFC4836] for the additional bonded xDSL-specific
operational states, GBOND-MIB provides these indications via the
gBondPortStatFltStatus object, complementing the ifOperStatus object
from the IF-MIB.
Finally, the EFM-CU-MIB does not include historical Performance
Monitoring (PM), while the GBOND-MIB/G9982-MIB/xDSL-LINE-MIB
combination provides full PM functionality for a bonded link and
individual xDSL lines.
4.4. Relationship to IEEE 802.3.1 MIB Modules
The IEEE 802.3 working group chartered a task force [IEEE802.3.1],
which continues the development of standard Ethernet-related MIB
modules based on the initial work done in the IETF. Future projects
resulting from the work of this task force may include and possibly
extend the work done in the IETF.
5. MIB Structure
5.1. Overview
The main management objects defined in the G9982-MIB module are split
into 2 groups, structured as recommended by RFC 4181 [RFC4181]:
o g9982Port - containing objects for configuration, capabilities,
status, and PM of G.Bond/Eth ports. Note that the rest of the
objects for the Generic Bonding Sub-layer (GBS) port
configuration, capabilities, status, notifications, and PM are
located in the GBOND-MIB module.
o g9982Bce - containing objects representing OPTIONAL status
information and BACP configuration for each Bonding Channel Entity
(BCE). Note that the rest of the objects for the BCE
configuration, capabilities, status, and notifications are located
in relevant xDSL line MIB modules as well as in the GBOND-MIB
module.
5.2. Performance Monitoring
The OPTIONAL Performance Monitoring counters, thresholds, and history
buckets (interval-counters), similar to those 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 interval SHOULD be aligned with the start of a day.
Counters are not reset when a GBS is re-initialized, but rather only
when the agent is reset or re-initialized.
5.3. Mapping of Broadband Forum TR-159 Managed Objects
This section contains the mapping between relevant managed objects
(attributes) defined in [TR-159] and the managed objects defined in
this document.

Table 1: Mapping of TR-159 Managed Objects
Note that some of the mapping between the objects defined in TR-159
and the ones defined in this MIB module is not one-to-one; for
example, while TR-159 PM attributes aGroupPerf* map to the
corresponding gBondPortPm* objects of the GBOND-MIB module, there are
no dedicated PM attributes for the g9982PortPm* objects introduced in
this MIB module. However, since their definition is identical to the
definition of gBondPortPm* objects of the GBOND-MIB module, we can
map g9982PortPm* to the relevant aGroupPerf* attributes of TR-159 and
use the term 'partial mapping' to denote the fact that this mapping
is not one-to-one.
6. G.Bond/Ethernet MIB Definitions
The G9982-MIB module IMPORTS objects from SNMPv2-SMI [RFC2578],
SNMPv2-TC [RFC2579], SNMPv2-CONF [RFC2580], IF-MIB [RFC2863], and
HC-PerfHist-TC-MIB [RFC3705]. The module has been structured as
recommended by [RFC4181].

7. Security Considerations
There are a number of managed objects defined in this MIB module with
a MAX-ACCESS clause of read-write and/or read-create. Such objects
may be considered sensitive or vulnerable in some network
environments. The support for SET operations in a non-secure
environment without proper protection can have a negative effect on
network operations. These are the tables and objects and their
sensitivity/vulnerability:
o Changing of g9982PortConfTable configuration parameters (e.g.,
g9982PortConfTcAdminType) may lead to a complete service
interruption in cases where the specified PTM-TC encapsulation
type is not supported by the remote end.
o Changing of g9982BceConfTable configuration parameters (e.g.,
g9982BceConfEligibleGroupID) may lead to preventing a non-bonded
BCE from being bonded in any bonding group, or false advertisement
of bonding eligibility (e.g., between BCEs residing on different
line cards in an application that does not support cross-card
bonding).
Some of the readable objects in this MIB module (i.e., objects with a
MAX-ACCESS other than not-accessible) may be considered sensitive or
vulnerable in some network environments since, collectively, they
provide information about the performance of network interfaces and
can reveal some aspects of their configuration.
It is thus important to control even GET and/or NOTIFY access to
these objects and possibly to even encrypt the values of these
objects when sending them over the network via SNMP. These are the
tables and objects and their sensitivity/vulnerability:
o g9982PortStatTable - objects in this table (e.g.,
g9982PortStatTcOperType) provide status information for the G.Bond
port, which may aid in deciphering of the G.Bond/ETH
transmissions.
SNMP versions prior to SNMPv3 did not include adequate security.
Even if the network itself is secure (for example by using IPSec),
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.
Implementations SHOULD provide the security features described by the
SNMPv3 framework (see [RFC3410]), and implementations claiming
compliance to the SNMPv3 standard MUST include full support for
authentication and privacy via the User-based Security Model (USM)
[RFC3414] with the AES cipher algorithm [RFC3826]. Implementations
MAY also provide support for the Transport Security Model (TSM)
[RFC5591] in combination with a secure transport such as SSH
[RFC5592] or TLS/DTLS [RFC6353].
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
IANA has assigned 264 as the object identifier for the g9982MIB
MODULE-IDENTITY in the MIB-2 transmission sub-tree
