1.  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 Very high speed Digital Subscriber Line (VDSL) interfaces
   [18, 19, 20].

   This document specifies a MIB module in a manner that is compliant
   to the SMIv2 (STD 58 [5, 6, 7]).

2.  The SNMP Management Framework

   The SNMP Management Framework presently consists of five major
   components:

   o   An overall architecture, described in RFC 2571 [1]. [RFC2571].

   o   Mechanisms for describing and naming objects and events for the
       purpose of management.  The first version of this Structure of
       Management Information (SMI) is called SMIv1 and described in
       STD 16, RFC 1155 [2], STD 16, RFC 1212 [3] 16 [RFC1155, RFC1212] and RFC 1215 [4]. [RFC1215].  The second
       version, called SMIv2, is described in STD 58, RFC
       2578 [5], STD 58, RFC 2579 [6] and STD 58, RFC 2580 [7]. 58 [RFC2578, RFC2579,
       RFC2580].

   o   Message protocols for transferring management information.  The
       first version of the SNMP message protocol is called SNMPv1 and
       described in STD 15, RFC 1157 [8]. 15 [RFC1157].  A second version of the SNMP
       message protocol, which is not an Internet standards track
       protocol, is called SNMPv2c and described in RFC 1901 [9] [RFC1901]
       and RFC 1906 [10]. [RFC1906].  The third version of the message
       protocol is called SNMPv3 and described in RFC 1906 [10], [RFC1906],
       RFC 2572 [11] [RFC2572] and RFC 2574 [12]. [RFC2574].

   o   Protocol operations for accessing management information.  The
       first set of protocol operations and associated PDU formats is
       described in STD 15, RFC 1157 [8]. 15 [RFC1157].  A second set of protocol
       operations and associated PDU formats is described in RFC 1905
       [13].
       [RFC1905].

   o   A set of fundamental applications described in RFC 2573 [14] [RFC2573]
       and the view-based access control mechanism described in RFC
       2575 [15]. [RFC2575].

   A more detailed introduction to the current SNMP Management Framework
   can be found in RFC 2570 [16]. [RFC2570].

   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB.  Objects in the MIB are
   defined using the mechanisms defined in the SMI.

   This memo specifies a MIB module that is compliant to the SMIv2.  A
   MIB conforming to the SMIv1 can be produced through the appropriate
   translations.  The resulting translated MIB must be semantically
   equivalent, except where objects or events are omitted because no
   translation is possible (use of Counter64).  Some machine readable
   information in SMIv2 will be converted into textual descriptions in
   SMIv1 during the translation process.  However, this loss of machine
   readable information is not considered to change the semantics of the
   MIB.

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED",  "MAY", and "OPTIONAL" in
   this document are to be interpreted as described in RFC 2119 [17].

3.  Introduction
   [RFC2119].

2.  Overview

   This document describes an SNMP MIB for managing VDSL Lines.  These
   definitions are based upon the specifications for VDSL as defined
   in [18, 19, 20]. T1E1, ETSI, and ITU documentation [T1E1311, T1E1011, T1E1013,
   ETSI2701, ETSI2702, ITU9931].

   The MIB is located in the MIB tree under MIB 2 transmission, as
   discussed in the MIB-2 Integration (RFC 2863 [23]) [RFC2863]) section of
   this document.

3.1 IANA Considerations

   The SNMPv2-TM MIB module requires the allocation of a single object
   identifier for its MODULE-IDENTITY.  IANA should allocate this object
   identifier in the snmpModules subtree, defined in the SNMPv2-SMI MIB
   module.

3.2.

2.1  Relationship of the VDSL Line MIB to other MIBs

   This section outlines the relationship of this MIB with other MIBs
   described in RFCs.  Specifically, IF-MIB as presented RFC 2863 [23]
   [RFC2863] is discussed.

3.2.1

2.1.1  General IF-MIB Integration (RFC 2863)

   The VDSL Line MIB specifies the detailed attributes of a data
   interface.  As such, it needs to integrate with RFC 2863 [23]. [RFC2863].
   The IANA has assigned the following ifType to VDSL:

   IANAifType ::= TEXTUAL-CONVENTION
       ...
   SYNTAX INTEGER {
       ...
       vdsl(97), -- Very H-speed Digital Subscrib. Loop
       ...

       }

3.2.2  Usage of ifTable

   The MIB branch identified by this ifType contains tables appropriate
   for this interface type.  Most such tables extend the ifEntry table,

   Additionally, a VDSL line may contain an optional fast channel
   and are an optional interleaved channel which also integrate into RFC
   2863 [RFC2863].  The IANA has assigned the following ifTypes to these
   channels:

   IANAifType ::= TEXTUAL-CONVENTION
       ...
   SYNTAX INTEGER {
       ...
       interleave (124), -- Interleave channel
       fast (125),       -- Fast channel
       ...
       }

2.1.2  Usage of ifTable

   The MIB branch identified by this ifType contains tables appropriate
   for this interface type.  Most such tables extend the ifEntry table,
   and are indexed by ifIndex.  For interfaces in systems implementing
   this MIB, those table entries indexed by ifIndex MUST be persistent.

   The following attributes are part of the mandatory ifGeneral group in
   RFC 2863 [23], [RFC2863], and are not duplicated in the VDSL Line MIB.

   ===================================================================
       ifIndex                  Interface index.

       ifDescr                  See interfaces MIB [21]. [RFC2863].

       ifType                   vdsl(97)                   vdsl(97),
                                interleaved(124), or
                                fast(125)

       ifSpeed                  Set as appropriate.

       ifPhysAddress            This object MUST have an octet string
                                with zero length.

       ifAdminStatus            See interfaces MIB [21]. [RFC2863].

       ifOperStatus             See interfaces MIB [21]. [RFC2863].

       ifLastChange             See interfaces MIB [21]. [RFC2863].

       ifName                   See interfaces MIB [21]. [RFC2863].

       ifLinkUpDownTrapEnable   Default to enabled(1).

       ifHighSpeed              Set as appropriate.

       ifConnectorPresent       Set as appropriate.

2.2.2 Textual Conventions

   The following textual conventions are defined to reflect the line
   topology in the MIB (further discussed in the following section)
   and to define the behavior of the statistics to be maintained
   by an agent.

   o    VdslLineCodingType :

   Attributes with this syntax identify the line coding used.
   Specified as an INTEGER, the three values are:

   other(1)  -- none of the following
   mcm(2)    -- Multiple Carrier Modulation
   scm(3)    -- Single Carrier Modulation

   o    VdslLineEntity :

   Attributes with this syntax reference the two sides of a line.
   Specified as an INTEGER, the two values are:

   vtuc(1)  -- central site modem
   vtur(2)  -- remote site modem

4.3.

2.3  Structure

   The MIB is structured into following MIB groups:

   o   vdslGroup :

   This group supports all line code independent MIB objects found
   in this MIB.  It contains the  The following tables: tables contain objects permitted for
   ifType vdsl(97):

       - vdslLineTable
       - vdslPhysTable
       - vdslChanTable
       - vdslPerfDataTable
       - vdslPerfIntervalTable
       - vdslChanPerfDataTable
       - vdslChanPerfIntervalTable vdslPerf1DayIntervalTable
       - vdslLineConfProfileTable
       - vdslLineAlarmConfProfileTable

   The following tables contain objects permitted for ifTypes
   interleaved(124) and (fast):

       - vdslChanTable
       - vdslChanPerfDataTable
       - vdslChanPerfIntervalTable
       - vdslChanPerf1DayIntervalTable

   o   vdslMCMGroup :

   This group supports MIB objects for defining configuration profiles
   for Multiple Carrier Modulation (MCM) VDSL modems.  It contains the
   following tables:

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

   Objects in this group MUST be implemented for MCM VDSL lines.

   o   vdslSCMGroup :

   This group supports MIB objects for defining configuration profiles
   for Single Carrier Modulation (SCM) VDSL modems.  It contains the
   following tables:

       - vdslLineSCMConfProfileTable
       - vdslLineSCMConfProfileTxBandTable

   This group also supports the following line code dependent tables:

       - vdslSCMPhysBandTable

   Objects in this group MUST be implemented for SCM VDSL lines.

4.3.1

   Figure 2, below, displays the relationship of the tables in the
   vdslGroup to ifEntry (and each other):

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

      vdslLineTableEntry  ----> vdslPhysTableEntry 1:(0..2)
                          ----> vdslPerfDataEntry 1:(0..2)
                          ----> vdslLineConfProfileEntry 1:(0..1)
                          ----> vdslLineAlarmConfProfileEntry 1:(0..1)

      vdslPhysTableEntry  ----> vdslPerfIntervalEntry 1:(0..96)
                          ----> vdslPerf1DayIntervalEntry 1:(0..30)

      ifEntry(ifType=124) ----> vdslChanEntry 1:(0..2)
                          ----> vdslChanPerfDataEntry 1:(0..2)
      ifEntry(ifType=125) ----> vdslChanEntry 1:(0..2)
                          ----> vdslChanPerfDataEntry 1:(0..2)

      vdslChanEntry       ----> vdslchanPerfIntervalEntry 1:(0..96)
                          ----> vdslchan1DayPerfIntervalEntry 1:(0..30)

                   Figure 2: Table Relationships

2.3.1  Line Topology

   A VDSL Line consists of a two units - Vtuc (the central termination
   unit) and a Vtur (the remote termination unit).

4.4.

2.4  Counters, Interval Buckets and Thresholds

   For Loss of Frame (lof), Loss of Link (lol), Loss of Signal (los),
   and Loss of Power (lpr), Errored Seconds (ES), Severely Errored
   Seconds (SES), and Unavailable Seconds (UAS) there are event counters,
   current 15-minute
   and 15-minute, 0 to 96 15-minute history bucket(s), and 0 to 30
   1-day history bucket(s) of "interval-counters".  Each current
   15-minute event bucket has an associated threshold notification.

   Each of these counters uses the textual conventions defined in the
   HC-PerfHist-TC-MIB.  The HC-PerfHist-TC-MIB is a work-in-progress,
   but simply defines 64-bit versions of the textual conventions
   found in RFC 2493 [21].

   Unlike RFC 2493 [21] and RFC 2662 [22], there [RFC2493].

   There is no representation
   in the MIB for invalid buckets.  In those cases where the data requirement for an interval is suspect or known to be invalid, the agent MUST NOT
   report the interval.  If the current 15-minute event bucket is
   determined to be invalid, notifications based upon ensure a fixed relationship
   between the value start of the
   event bucket MUST NOT be generated.

   Not reporting an interval will result in holes in the associated
   table.  For example, the table, vdslPerfIntervalTable, is indexed
   by { ifIndex, vdslPhysSide, vdslIntervalNumber }.  If interval 12
   is determined to be invalid but intervals 11 and 13 are valid, a
   Get Next operation on the indices .1.1.11 would return indices
   .1.1.13.

   There is no requirement for an agent to ensure a fixed relationship
   between the start of a fifteen minute and any wall clock; however
   some implementations may align a fifteen minute and any wall clock; however
   some implementations may align the fifteen minute intervals with
   quarter hours. Likewise, an implementation may choose to align one
   day intervals with the start of a day.

   Counters are not reset when an Vtu is reinitialized, only when the
   agent is reset or reinitialized (or under specific request outside
   the scope of this MIB).

4.5.

2.5  Profiles

   As a managed node can handle a large number of Vtus, (e.g., hundreds
   or perhaps thousands of lines), provisioning every parameter on every
   Vtu may become burdensome.  Moreover, most lines are provisioned
   identically with the same set of parameters.  To simplify the
   provisioning process, this MIB makes use of profiles.  A profile is a
   set of parameters that can be shared by multiple lines using the same
   configuration.

   The following profiles are used in this MIB:

   o   Line Configuration Profiles - Line configuration profiles contain
       parameters for configuring VDSL lines.  They are defined in eight nine
       tables:

       - vdslLineConfProfileTable
       - vdslLineMCMConfProfileTable
       - vdslLineMCMConfProfileTxBandTable
       - vdslLineMCMConfProfileRxBandTable
       - vdslLineMCMConfProfileTxPSDTable
       - vdslLineMCMConfProfileMaxTxPSDTable
       - vdslLineMCMConfProfileMaxRxPSDTable
       - vdslLineSCMConfProfileTable
       - vdslLineSCMConfProfileTxBandTable

       As noted above, the latter seven eight tables in the above list are
       line code specific.

       The object, vdslLineConfProfileIndex, is used as a common
       index for all of the above tables.  A profile, then, consists
       of the combination of a line code independent configuration
       (i.e. an entry in vdslLineConfProfileTable) and a set of line
       code dependent configurations (i.e. entries in either
       vdslLineMCMConfProfilexxx or vdslLineSCMConfProfilexxx).

   o   Alarm Configuration Profiles - These profiles contain parameters
       for configuring alarm thresholds for VDSL modems.  These profiles
       are defined in the vdslLineAlarmConfProfileTable.

   One or more lines may be configured to share parameters of a single
   profile by setting its vdslLineConfProfile objects to the value of
   this profile. If a change is made to the profile, all lines that
   refer to it will be reconfigured to the changed parameters.  Before
   a profile can be deleted or taken out of service it must be first
   unreferenced from all associated lines.

   Implementations MUST provide a default profile with an index value
   of 1 for each profile type.  The values of the associated parameters
   will be vendor specific unless otherwise indicated in this document.
   Before a line's profiles have been set, these profiles will be
   automatically used by setting vdslLineConfProfile and
   vdslLineAlarmConfProfile to 1 where appropriate.  This default
   profile entry is considered reserved in the context of profiles
   defined in this MIB.

   Profiles are created, assigned, and deleted dynamically using the
   profile name and profile row status in each of the four profile
   tables.

   Profile changes MUST take effect immediately.  These changes MAY
   result in a restart (hard reset or soft restart) of the units on the
   line.

4.6.

2.6  Notifications

   The ability to generate the SNMP notifications coldStart/WarmStart
   (per [21]) [RFC2863]) which are per agent (e.g., per Digital Subscriber Line
   Access Multiplexer, or DSLAM, in such a device), and linkUp/linkDown
   (per [21]) [RFC2863]) which are per interface (i.e., VDSL line) is required.

   For Loss of Frame (lof), Loss of Link (lol), Loss of Signal (los),
   and Loss of Power (lpr),

   A linkDown notification MAY be generated whenever any of lof, lol,
   los, or lpr event occurs.  The corresponding linkUp notification MAY
   be sent when all link failure conditions are cleared.

   The notifications defined in this MIB are for initialization failure
   and for the threshold crossings associated with the following events:
   lof, lol, los, lpr, ES, SES, and lpr. UAS.  Each threshold has its own
   enable/threshold value. When that value is 0, the notification is
   disabled.

   A linkDown notification MAY be generated whenever any of lof, lol,
   los, lpr, ES, SES, or UAS threshold crossing event (as defined
   in this MIB) occurs.  The corresponding linkUp notification MAY be
   sent when all link failure conditions are cleared.

   The vdslCurrStatus is a bitmask representing all outstanding error
   conditions associated with a particular VDSL modem.  Note that since
   status of remote modems is obtained via the EOC, this information
   may be unavailable for units that are unreachable via EOC during a
   line error condition.  Therefore, not all conditions may always be
   included in its current status.  Notifications corresponding to the
   bit fields in this object are defined.

   A threshold notification occurs whenever the corresponding current
   15-minute interval error counter becomes equal to, or exceeds the
   threshold value. One notification may be sent per interval per
   interface. Since the current 15-minute counter are reset to 0 every
   15 minutes, if the condition persists, the notification may recur as
   often as every 15 minutes.  For example, to get a notification
   whenever a "loss of" event occurs (but at most once every 15
   minutes), set the corresponding threshold to 1. The agent will
   generate a notification when the event originally occurs.

   Note that the Network Management System, or NMS, may receive a
   linkDown notification, as well, if enabled (via
   ifLinkUpDownTrapEnable [23]). [RFC2863]). At the beginning of the next 15 minute
   interval, the counter is reset.  When the first second goes by and
   the event occurs, the current interval bucket will be 1, which
   equals the threshold and the notification will be sent again.

    DESCRIPTION
        "The MIB module defining objects for the management of a pair of
        VDSL modems at each end of the VDSL line.  Each such line has
        an entry in an ifTable which may include multiple modem lines.
        An agent may reside at either end of the VDSL line however the
        MIB is designed to require no management communication between
        them beyond that inherent in the low-level VDSL line protocol.
        The agent may monitor and control this protocol for its needs.

        VDSL lines may support optional Fast or Interleaved channels.
        If these are supported, additional entries corresponding to the
        supported channels must be created in the ifTable. Thus a VDSL
        line that supports both channels will have three entries in the
        ifTable, one for each physical, fast, and interleaved, whose
        ifType values are equal to vdsl(97), fast(125), and
        interleaved(124), respectively. The ifStackTable is used to
        represent the relationship between the entries.

        Naming Conventions:
            Vtuc -- (VTUC) modem at near (Central) end of line
            Vtur -- (VTUR) modem at Remote end of line
            Vtu  -- One of either Vtuc or Vtur
            Curr -- Current

Security Considerations

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

   VDSL layer connectivity from the Vtur will permit the subscriber

   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.

   For this reason, there are a number of managed objects in this MIB
   that may contain sensitive information. These are:

        vdslThresh15MinLofs
        vdslThresh15MinLoss
        vdslThresh15MinLprs
        vdslThresh15MinESs

        vdslThresh15MinSESs
        vdslThresh15MinUASs

   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.

   Further, notifications generated by agents implementing this MIB
   will contain the above threshold information.

   SNMPv1 by itself is not a secure environment.  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.

   It is recommended that the implementers consider the security
   features as provided by the SNMPv3 framework.  Specifically, the use
   of the Simple Network Management Protocol
   (SNMPv2)", RFC 1905, January 1996.
