Abstract
This document defines a portion of the Management Information Base
(MIB) module for use with network management protocols in the
Internet community. In particular, it describes objects used for
managing the Line Code Specific parameters of Very High Speed Digital
Subscriber Line (VDSL) interfaces using Multiple Carrier Modulation
(MCM) Line Coding. It is an optional extension to the VDSL-LINE-MIB,
<a href="./rfc3728">RFC 3728</a>, which handles line code independent objects.

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,
<a href="./rfc2578">RFC 2578</a> [<a href="./rfc2578" title=""Structure of Management Information Version 2 (SMIv2)"">RFC2578</a>], STD 58, <a href="./rfc2579">RFC 2579</a> [<a href="./rfc2579" title=""Textual Conventions for SMIv2"">RFC2579</a>] and STD 58, <a href="./rfc2580">RFC 2580</a>

<span class="h2"><a class="selflink" id="section-2" href="#section-2">2</a>. Overview</span>
This document describes an SNMP MIB module for managing the Line Code
Dependent, Physical Medium Dependent (PMD), Layer of MCM VDSL Lines.
These definitions are based upon the specifications for VDSL as
defined in T1E1, European Telecommunications Standards Institute
(ETSI), and International Telecommunication Union (ITU) documentation
[<a href="#ref-T1E1311" title=""Very-high-bit-rate Digital Subscriber Line (VDSL) Metallic Interface, Part 1: Functional Requirements and Common Specification"">T1E1311</a>, <a href="#ref-T1E1011" title=""VDSL Metallic Interface, Part 2: Technical Specification for a Single-Carrier Modulation (SCM) Transceiver"">T1E1011</a>, <a href="#ref-T1E1013" title=""VDSL Metallic Interface, Part 3: Technical Specification for a Multi-Carrier Modulation (MCM) Transceiver"">T1E1013</a>, <a href="#ref-ETSI2701" title=""Transmission and Multiplexing (TM); Access transmission systems on metallic access cables; Very high speed Digital Subscriber Line (VDSL); Part 1: Functional requirements"">ETSI2701</a>, <a href="#ref-ETSI2702" title=""Transmission and Multiplexing (TM); Access transmission systems on metallic access cables; Very high speed Digital Subscriber Line (VDSL); Part 1: Transceiver specification"">ETSI2702</a>, <a href="#ref-ITU9931" title=""Very-high-speed digital subscriber line foundation"">ITU9931</a>, <a href="#ref-ITU9971" title=""Physical layer management for Digital Subscriber Line (DSL) Transceivers"">ITU9971</a>].
Additionally the protocol-dependent (and line-code dependent)
management framework for VDSL lines specified by the Digital
Subscriber Line Forum (DSLF) has been taken into consideration
[<a href="#ref-DSLFTR57" title=""VDSL Network Element Management"">DSLFTR57</a>].

The MCM VDSL Line Extension MIB contains the following MIB group:
o vdslMCMGroup :
This group supports MIB objects for defining configuration profiles
and for monitoring individual bands of Multiple Carrier Modulation
(MCM) VDSL modems. It contains the following tables:
- vdslLineMCMConfProfileTable
- vdslLineMCMConfProfileTxBandTable
- vdslLineMCMConfProfileRxBandTable
- vdslLineMCMConfProfileTxPSDTable
- vdslLineMCMConfProfileMaxTxPSDTable
- vdslLineMCMConfProfileMaxRxPSDTable
If the MCM VDSL Line Extension MIB is implemented then all of the
objects in this group MUST be implemented.

<span class="grey"><a href="./rfc4070">RFC 4070</a> VDSL-LINE-EXT-MCM-MIB May 2005</span>
Figure 1, below, displays the relationship of the tables in the
vdslMCMGroup to the vdslGroup and to the ifEntry:
ifEntry(ifType=97) ----> vdslLineTableEntry 1:(0..1)
vdslLineTableEntry (vdslLineCoding=MCM)
vdslLineConfProfileEntry(vdslLineConfProfileName)
----> vdslLineMCMConfProfileTable 1:(0..1)

----> vdslLineMCMConfProfileMaxTxPSDTable 1:(0..n)
----> vdslLineMCMConfProfileMaxRxPSDTable 1:(0..n)
Figure 1: Table Relationships
When the object vdslLineCoding is set to MCM, vdslLineConfProfileName
is used as the index to each of the six vdslLineMCMConfProfile
Tables. The existence of an entry in any of the tables of the
vdslMCMGroup is optional.
<span class="h3"><a class="selflink" id="section-2.4" href="#section-2.4">2.4</a>. Persistence</span>

DESCRIPTION
"The VDSL-LINE-MIB found in <a href="./rfc3728">RFC 3728</a> defines objects for
the management of a pair of VDSL transceivers at each end of
the VDSL line. The VDSL-LINE-MIB configures and monitors the
line code independent parameters (TC layer) of the VDSL line.
This MIB module is an optional extension of the VDSL-LINE-MIB
and defines objects for configuration and monitoring of the
line code specific (LCS) elements (PMD layer) for VDSL lines
using MCM coding. The objects in this extension MIB MUST NOT
be used for VDSL lines using Single Carrier Modulation (SCM)
line coding. If an object in this extension MIB is referenced
by a line which does not use MCM, it has no effect on the
operation of that line.
Naming Conventions:
Vtuc -- (VTUC) transceiver at near (Central) end of line
Vtur -- (VTUR) transceiver at Remote end of line
Vtu -- One of either Vtuc or Vtur
Curr -- Current
LCS -- Line Code Specific
Max -- Maximum
PSD -- Power Spectral Density
Rx -- Receive
Tx -- Transmit

of this MIB module is part of <a href="./rfc4070">RFC 4070</a>: see the RFC

This document contains many definitions taken from an early version
of the VDSL MIB [<a href="./rfc3728" title=""Definitions of Managed Objects for Very High Speed Digital Subscriber Lines (VDSL)"">RFC3728</a>]. As such any credit for the text found

<span class="h2"><a class="selflink" id="section-6" href="#section-6">6</a>. Security Considerations</span>
There are a number of management objects defined in this MIB module
with a MAX-ACCESS clause of 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:

vdslLineMCMConfProfileTxWindowLength,
vdslLineMCMConfProfileRowStatus,
vdslLineMCMConfProfileTxBandTable,
vdslLineMCMConfProfileTxBandStart,

VDSL layer connectivity from the Vtur will permit the subscriber to
manipulate both the VDSL link directly and the VDSL embedded
operations channel (EOC) for their own loop. For example, unchecked
or unfiltered fluctuations initiated by the subscriber could generate
sufficient notifications to potentially overwhelm either the
management interface to the network or the element manager.
Additionally, allowing write access to configuration data may allow
an end-user to increase their service levels or affect other end-
users in either a positive or negative manner. For this reason, the
tables and objects listed above should be considered to contain
sensitive information.
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. 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:
vdslLineMCMConfProfileTable,
vdslLineMCMConfProfileTxWindowLength,
vdslLineMCMConfProfileRowStatus,
vdslLineMCMConfProfileTxBandTable,
vdslLineMCMConfProfileTxBandStart,

Read access of the physical band parameters may provide knowledge to
an end-user that would allow malicious behavior, for example the
application of an intentional interference on one or all of the
physical bands in use.
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 <a href="./rfc3410#section-8">[RFC3410], section 8</a>),
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 a MIB module which utilizes the textual conventions
defined in 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.
