Internet-Draft G.Bond ATM MIB May 2011
1. Introduction
The ATM-Based Multi-Pair Bonding, a.k.a. G.Bond/ATM, is 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. As with the
other bonding schemes, ATM bonding also allows bonding of up to 32
individual sub-layers with variable rates, providing common
functionality for the configuration, initialization, operation and
monitoring of the bonded link.
The MIB module, defined in this document, defines a set of managed
objects for the management of G.998.1 bonded interfaces, extending
the common objects specified in the GBOND-MIB
[I-D.ietf-adslmib-gbond-mib] module.
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 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.
Beili Expires November 27, 2011 [Page 3]
Internet-Draft G.Bond ATM MIB May 2011
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) and G.Bond MIB (GBOND-MIB).
4.1. Relationship to Interfaces Group MIB module
A G.Bond/ATM 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/ATM ports, as
well as xDSL lines/channels, in a managed system.
4.2. Relationship to G.Bond MIB module
GBOND-MIB [I-D.ietf-adslmib-gbond-mib] module defines management
objects common for all Bonded multi-pair xDSL interfaces. In
particular it describes the bonding management, bonded port and
channel configuration, initialization sequence etc.
Both GBOND-MIB and GBOND-ATM-MIB modules are REQUIRED to manage a
G.Bond/ATM port.
4.3. Relationship to ATM MIB module
ATM-MIB [RFC2515] module defines management objects for an ATM
interface.
ATM-MIB module can be used to manage the ATM aspects of a G.Bond/ATM
port.
5. MIB Structure
5.1. Overview
All management objects defined in the GBOND-ATM-MIB module are
contained in a single group gBondAtmPort. This group is further
split into 4 sub-groups, structured as recommended by RFC 4181
[RFC4181]:
o gBondTdimPortNotifications - containing notifications (Up/
Downstream Diff. Delay Tolerance Exceeded).
o gBondAtmPortConfTable - containing objects for configuration of a
G.Bond/ATM port.
Beili Expires November 27, 2011 [Page 4]
Internet-Draft G.Bond ATM MIB May 2011
o gBondAtmPortStatusTable - containing objects providing overall
status information of a G.Bond/ATM port, complementing the generic
status information from the ifTable of IF-MIB and gBondFltStatus
of GBOND-MIB.
o gBondAtmPM - containing objects providing historical performance
monitoring (PM) information of a G.Bond/ATM port, complementing
the PM information from the gBondPortPM of GBOND-MIB.
Note that the rest of the objects for the Generic Bonded Sub-layer
(GBS) port configuration, capabilities, status, notifications and
performance monitoring is located in the GBOND-MIB module.
5.2. Performance Monitoring
The OPTIONAL performance monitoring counters, thresholds and history
buckets (interval-counters) 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, but rather only
when the agent is reset or reinitialized (or under specific request
outside the scope of this MIB module).
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.

7. Security Considerations
There is a number of managed objects defined in the GBOND-ATM-MIB
module that have a MAX-ACCESS clause of read-write. Writing to these
objects can have potentially disruptive effects on network operation,
for example:
o Changing of gBondAtmPortConfTable configuration parameters MAY
lead to a potential Service Level Agreement (SLA) breach, for
example if a traffic delay is increased as a result of the higher
delay tolerance (increased gBondAtmUpDiffDelayTolerance and/or
gBondAtmDnDiffDelayTolerance), or the differential delay tolerance
notifications are disabled by manipulating the
gBondAtmDiffDelayToleranceExceededEnable parameter.
The user of the GBOND-ATM-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-ATM-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 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 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).
Beili Expires November 27, 2011 [Page 29]
Internet-Draft G.Bond ATM MIB May 2011
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
An object identifier for gBondAtmMIB MODULE-IDENTITY SHALL be
allocated by IANA [1] in the MIB-2 transmission sub-tree, before this
document is published as an RFC.
