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, RFC 3728 [RFC3728], which handles line code 
   independent objects.

1.  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 "MAY", "MUST", "MUST NOT", "RECOMMENDED", 
   "NOT RECOMMENDED", and "SHOULD" in this document are to be 
   interpreted as described in [RFC2119].

2.  Overview

   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
   [T1E1311, T1E1011, T1E1013, ETSI2701, ETSI2702, ITU9931, ITU9971].  
   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 
   [DSLFTR057].

   The MIB module is located in the MIB tree under the vdslMIB, which 
   in turn is found under MIB 2 transmission.  The reader is referred to

   RFC 3728 [RFC3728] for further discussion of this subject.

2.1  Relationship of this MIB Module to other MIB Modules

   The relationship of the VDSL Line MIB module to other MIB modules 
   and in particular to the IF-MIB, as presented in RFC 2863 [RFC2863],
   is discussed in the VDSL-LINE-MIB, RFC 3728 [RFC3728].  This section 
   outlines the relationship of this VDSL Line Extension MIB to the
   VDSL-LINE-MIB, RFC 3728 [RFC3728].

2.2 Conventions used in the MIB Module

2.2.1 Naming Conventions

   A.  Vtuc -- (VTUC) transceiver at near (Central) end of line
   B.  Vtur -- (VTUR) transceiver at Remote end of line
   C.  Vtu  -- One of either Vtuc or Vtur
   D.  Curr -- Current
   E.  LCS  -- Line Code Specific
   F.  Max  -- Maximum
   G.  PSD  -- Power Spectral Density
   H.  Rx   -- Receive
   I.  Tx   -- Transmit

2.3  Structure

   The MCM VDSL Line Extension MIB contains the following MIB group:

   o   vdslMCMGroup :

   This group supports MIB objects for defining configuration profiles
   and for montioring 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. 

   Figure 1, below, displays the relationship of the tables in the
   vdslMCMGroup to the vdslGroup and to the ifEntry:

                 ----> 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 
   vdslLineMCMConfProfileTxBandTable.  The existence of an entry in 
   any of the tables of the vdslMCMGroup is optional.  
 
2.4  Persistence

   All read-create objects defined in this MIB module SHOULD be stored 
   persistently.  Following is an exhaustive list of these persistent 
   objects:

        vdslMCMConfProfileTxWindowLength
        vdslMCMConfProfileRowStatus
        vdslMCMConfProfileTxBandNumber
        vdslMCMConfProfileTxBandStart
        vdslMCMConfProfileTxBandStop
        vdslMCMConfProfileTxBandRowStatus
        vdslMCMConfProfileRxBandStart
        vdslMCMConfProfileRxBandStop
        vdslMCMConfProfileRxBandRowStatus
        vdslMCMConfProfileTxPSDTone
        vdslMCMConfProfileTxPSDPSD
        vdslMCMConfProfileTxPSDRowStatus
        vdslMCMConfProfileMaxTxPSDTone
        vdslMCMConfProfileMaxTxPSDPSD
        vdslMCMConfProfileMaxTxPSDRowStatus
        vdslMCMConfProfileMaxRxPSDTone
        vdslMCMConfProfileMaxRxPSDPSD
        vdslMCMConfProfileMaxRxPSDRowStatus
 
   Note also that the interface indices in this MIB are maintained 
   persistently.  View-based Access Control Model (VACM) data 
   relating to these SHOULD be stored persistently as well [RFC3415].

3. Conformance and Compliance

   An MCM based VDSL agent does not have to implement this MIB to be 
   compliant with RFC 3728 [RFC3728].  If the MCM VDSL Line Extension 
   MIB is implemented then the following group is mandatory:

   -  vdslMCMGroup

INTERNET-DRAFT           VDSL-LINE-EXT-MCM-MIB               March  2004

    DESCRIPTION 
        "The VDSL-LINE-MIB found in RFC 3728 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.

INTERNET-DRAFT           VDSL-LINE-EXT-MCM-MIB               March  2004

5. Acknowledgments

   This document contains many definitions taken from
   draft-ietf-adslmib-vdsl-07.txt.  As such, any credit for the text 
   found within should be fully attributed to the authors of that
   document.
 
6. Security Considerations

   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.  

   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.  

   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
   following tables should be considered to contain sensitive
   information:

       - vdslLineMCMConfProfileTable 
       - vdslLineMCMConfProfileTxBandTable
       - vdslLineMCMConfProfileRxBandTable
       - vdslLineMCMConfProfileTxPSDTable 
       - vdslLineMCMConfProfileMaxTxPSDTable 
       - vdslLineMCMConfProfileMaxRxPSDTable 

   It is thus important to control even GET access to the objects within
   these tables and possibly to even encrypt the values of these objects
   when sending them over the network via SNMP.  Not all versions of
   SNMP provide features for such a secure environment.

   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),

INTERNET-DRAFT           VDSL-LINE-EXT-MCM-MIB               March  2004

   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.

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 Single Carrier 
   Modulation (SCM) Line Coding.  It is an optional extension to the 
   VDSL-LINE-MIB, RFC 3728 [RFC3728], which handles line code 
   independent objects.

1.  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].

2.  Overview

   This document describes an SNMP MIB module for managing the line  
   code dependent (Physical Medium Dependent) Layer of SCM VDSL Lines.
   These definitions are based upon the specifications for VDSL as 
   defined in T1E1, ETSI, and ITU documentation [T1E1311, T1E1011, 
   T1E1013, ETSI2701, ETSI2702, ITU9931, ITU9971].  Additionally the 
   protocol-dependent (and line-code dependent) management framework 
   for VDSL lines specified by DSLF has been taken into consideration

2.3  Structure

   The SCM VDSL Line Extension MIB contains the following MIB group:

   o   vdslSCMGroup :

   This group supports MIB objects for defining configuration profiles
   and for montioring individual bands of Single Carrier Modulation
   (SCM) VDSL modems.  It contains the following tables:
   
       - vdslLineSCMConfProfileTxBandTable 
       - vdslSCMPhysBandTable

   None, one or both objects in this group MAY be implemented for
   SCM VDSL lines.

   Figure 1, below, displays the relationship of the tables in the
   vdslSCMGroup to the vdslGroup and to the ifEntry:

     ifEntry(ifType=97)  ----> vdslLineTableEntry 1:(0..1)

      vdslLineTableEntry (vdslLineCoding=SCM)
            ----> vdslPhysTableEntry 1:(0..2)
                ----> vdslSCMPhysBandTable 1:(0..6)
 
      
      vdslLineConfProfileEntry(vdslLineConfProfileName)
                    ----> vdslLineSCMConfProfileBandTable 1:(0..6)

INTERNET-DRAFT            VDSL-LINE-EXT-SCM-MIB               March 2004
     When the object vdslLineCoding is set to SCM, 
     vdslLineConfProfileName is used as the index to 
     vdslLineSCMConfProfileBandTable.  The existence of an entry in 
     any of the tables of the vdslSCMGroup is optional. None, some or 
     all of the vdslSCMGroup tables MAY be implemented for a particular 
     VDSL line entity using SCM line coding. 
     
2.4  Persistence

   All read-create objects defined in this MIB module SHOULD be stored 
   persistently.  Following is an exhaustive list of these persistent 
   objects:
                      
    vdslSCMConfProfileBandId  
    vdslSCMConfProfileBandUsage          
    vdslSCMConfProfileBandCenterFrequency   
    vdslSCMConfProfileBandSymbolRate        
    vdslSCMConfProfileBandConstellationSize 
    vdslSCMConfProfileBandTransmitPSDLevel  
    vdslSCMConfProfileBandRowStatus                       
    vdslSCMPhysBandId  
    vdslSCMPhysBandUsage                         
    vdslSCMPhysBandCurrPSDLevel         
    vdslSCMPhysBandCurrSymbolRate       
    vdslSCMPhysBandCurrConstellationSize 
    vdslSCMPhysBandCurrCenterFrequency  
    vdslSCMPhysBandPerformanceBandId  
    vdslSCMPhysBandPerformanceBandUsage  
    vdslSCMPhysBandPerformanceBandSnrMgn           
    vdslSCMPhysBandPerformanceBandAtn     

 
   It SHOULD also be noted that interface indices in this MIB are 
   maintained persistently.  VACM data relating to these SHOULD be 
   stored persistently as well [RFC2575].

    DESCRIPTION 
        "The VDSL-LINE-MIB found in RFC 3728 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 
        SCM coding. The objects in this extension MIB MUST NOT be used
        for VDSL lines using MCM line coding.
        
        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

5. Security Considerations

   There are a number of management objects defined in this MIB that
   have 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.

   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.  

   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
   following tables should be considered to contain sensitive
   information:

       - vdslLineSCMConfProfileTxBandTable 
       - vdslSCMPhysBandTable

   It is thus important to control even GET access to these objects and
   possibly to even encrypt the values of these objects when sending 
   them over the network via SNMP.  Not all versions of SNMP provide 
   features for such a secure environment.
   
   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 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
