Internet-Draft G.Bond ATM MIB March 2012
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 September 13, 2012 [Page 3]
Internet-Draft G.Bond ATM MIB March 2012
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 G9981-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 G9981-MIB module are contained
in a single group g9981Port. This group is further split into 4 sub-
groups, structured as recommended by RFC 4181 [RFC4181]:
o g9981PortNotifications - containing notifications (Up/Downstream
Differential Delay Tolerance Exceeded).
o g9981PortConfTable - containing objects for configuration of a
G.Bond/ATM port.
Beili Expires September 13, 2012 [Page 4]
Internet-Draft G.Bond ATM MIB March 2012
o g9981PortStatusTable - 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 g9981PM - 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.
Note that the accumulation of certain performance events for a
monitored entity is inhibited (counting stops) during periods of
service unavailability on that entity. The DESCRIPTION clause of
performance monitoring counters in this MIB module specifies which of
the counters are inhibited during periods of service unavailability.
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 this MIB module with
a MAX-ACCESS clause of read-write. 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 g9981PortConfTable 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 g9981PortConfUpDiffDelayTolerance and/or
g9981PortConfDnDiffDelayTolerance), or the differential delay
tolerance notifications are disabled by manipulating the
g9981PortConfDiffDelayToleranceExceededEnable parameter.
Some of the readable objects in this MIB module (i.e., those with
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 even encrypt the values of these objects
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),
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 MUST provide the security features described by the
SNMPv3 framework (see [RFC3410]), including 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.
