The Internet-Standard Management Framework   For a detailed overview of the documents that describe the current   Internet-Standard Management Framework, please refer toSection 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", "MAY", and "OPTIONAL" in this   document are to be interpreted as described inRFC 2119 [RFC2119].2.  Overview   This document defines a Management Information Base (MIB) module for   use with network management protocols in the Internet community for   the purpose of managing VDSL2, ADSL, ADSL2, and ADSL2+ lines.Morgenstern, et al.         Standards Track                     [Page 2]

RFC 5650                     VDSL2-LINE MIB               September 2009   The MIB module described inRFC 2662 [RFC2662] describes objects used   for managing Asymmetric Bit-Rate DSL (ADSL) interfaces per   [T1E1.413], [G.992.1], and [G.992.2].  These object descriptions are   based upon the specifications for the ADSL Embedded Operations   Channel (EOC) as defined in American National Standards Institute   (ANSI) T1E1.413/1995 [T1E1.413] and International Telecommunication   Union (ITU-T) G.992.1 [G.992.1] and G.992.2 [G.992.2].   The MIB module described inRFC 4706 [RFC4706] is a wider management   model that includes, in addition to ADSL technology, the ADSL2 and   ADSL2+ technologies per G.992.3, G.992.4, and G.992.5 ([G.992.3],   [G.992.4], and [G.992.5], respectively).   This document does not obsoleteRFC 2662 [RFC2662] orRFC 4706   [RFC4706], but rather provides a more comprehensive management model   that addresses the VDSL2 technology per G.993.2 ([G.993.2]) as well   as ADSL, ADSL2, and ADSL2+ technologies.   This document does not obsoleteRFC 2662 [RFC2662] orRFC 4706   [RFC4706].RFC 2662 is relevant only for managing modems that do not   support any DSL technology other than ADSL (e.g., G.992.1 [G.992.1]   and G.992.2 [G.992.2]) especially if the modems were produced prior   to approval of ITU-T G.997.1 standard revision 3 [G.997.1].RFC 4706   is more appropriate for managing modems that support ADSL2 technology   variants (with or without being able to support the legacy ADSL).   This document supports all ADSL, ADSL2, and VDSL2 standards, but it   assumes a more sophisticated management model, which older modems   (even ADSL2 ones) may not be able to support.  The selection of the   appropriate MIB module for any DSL modem is based on the ifType value   it reports, as explained in the next section.   The management framework for VDSL2 lines [TR-129] specified by the   Digital Subscriber Line Forum (DSLF) has been taken into   consideration.  That framework is based on the ITU-T G.997.1 standard   [G.997.1] and its amendment 1 [G.997.1-Am1].   Note that the management model, according to this document, does not   allow managing VDSL technology per G.993.1 [G.993.1].  VDSL lines   MUST be managed byRFC 3728 [RFC3728].   The MIB module is located in the MIB tree under MIB 2 transmission,   as discussed in the MIB-2 Integration (RFC 2863 [RFC2863]) section of   this document.Morgenstern, et al.

RFC 5650                     VDSL2-LINE MIB               September 20092.1.  Relationship to Other MIBs   This section outlines the relationship of this MIB module with other   MIB modules described in RFCs.  Specifically, IF-MIB as defined inRFC 2863 [RFC2863] and ENTITY-MIB as defined inRFC 4133 [RFC4133]   are discussed.2.1.1.  Relationship with IF-MIB (RFC 2863)2.1.1.1.  General IF-MIB Integration   The VDSL2 Line MIB specifies the detailed objects of a data   interface.  As such, it needs to integrate withRFC 2863 [RFC2863].   The IANA has assigned the following ifTypes, which may be applicable   for VDSL2 lines as well as for ADSL, ADSL2, and ADSL2+ lines:   IANAifType ::= TEXTUAL-CONVENTION       ...   SYNTAX INTEGER {       ...       channel(70),     -- Channel       adsl(94),        -- Asymmetric Digital Subscriber Loop       ...       interleave(124), -- Interleaved Channel       fast(125),       -- Fast Channel       ...       adsl2plus(238),  -- Asymmetric Digital Subscriber Loop Version 2,                           Version 2 Plus, and all variants       vdsl2(251),      -- Very High Speed Digital Subscriber Loop 2       ...       }   ADSL lines that are identified with ifType=adsl(94) MUST be managed   with the MIB specified byRFC 2662.  ADSL, ADSL2, and ADSL2+ lines   identified with ifType=adsl2plus(238) MUST be managed with the MIB   specified byRFC 4706 [RFC4706].  VDSL2, ADSL, ADSL2, and ADSL2+   lines identified with ifType=vdsl2(251) MUST be managed with the MIB   specified by this document.   In any case, the SNMP agent may use either ifType=interleave(124) or   fast(125) for each channel, e.g., depending on whether or not it is   capable of using an interleaver on that channel.  It may use the   ifType=channel (70) when all channels are capable of using an   interleaver (e.g., for ADSL2 xTUs).   Note that the ifFixedLengthGroup fromRFC 2863 [RFC2863] MUST be   supported and that the ifRcvAddressGroup does not apply to this MIB   module.Morgenstern, et al.

RFC 5650                     VDSL2-LINE MIB               September 20092.1.1.2.  Usage of ifTable   The MIB branch identified by ifType contains tables appropriate for   the interface types described above.  Most such tables extend the   ifEntry table, and are indexed by ifIndex.  For interfaces in systems   implementing this MIB module, those table entries indexed by ifIndex   MUST be persistent.   The following objects are part of the mandatory   ifGeneralInformationGroup in the Interfaces MIB [RFC2863], and are   not duplicated in the VDSL2 Line MIB.      ifIndex                  Interface index.      ifDescr                  See interfaces MIB.      ifType                   vdsl2(251), channel(70),                               interleave(124), or fast(125)      ifSpeed                  Set as appropriate.      ifPhysAddress            This object MUST have an octet                               string with zero length.      ifAdminStatus            See interfaces MIB.      ifOperStatus             See interfaces MIB.      ifLastChange             See interfaces MIB.      ifName                   See interfaces MIB.      ifAlias                  See interfaces MIB.      ifLinkUpDownTrapEnable   Default to enabled(1).      ifHighSpeed              Set as appropriate.      ifConnectorPresent       Set as appropriate.   -------------------------------------------------------------------                     Figure 1: Use of ifTable Objects2.1.1.3.  Usage of ifStackTable   Use of the ifStackTable to associate the entries for physical, fast,   interleaved channels, and higher layers (e.g., ATM) is shown below.   Use of the ifStackTable is necessary because configuration   information is stored in profile tables associated with the physical-Morgenstern, et al.

The channels' ifEntrys need the ifStackTable to   find their associated physical-layer entry and thus their   configuration parameters.  The following example shows the   ifStackTable entries for an xDSL line with a single channel that uses   an ATM data path.

Relationship with the ENTITY-MIB (RFC 4133)   Implementation of the Entity MIB [RFC4133] is optional.  It in no way   alters the information required in the VDSL2 Line MIB, nor does it   alter the relationship with IF-MIB.   The Entity MIB introduces a standardized way of presenting the   components of complex systems, such as a Digital Subscriber Line   Access Multiplexer (DSLAM), that may contain multiple racks, shelves,   line cards, and/or ports.  The Entity MIB's main goal is to present   these system components, their containment relationship, and mapping   information with other MIBs such as the Interface MIB and the VDSL2   Line MIB.   The Entity MIB is capable of supporting the local DSL termination   unit.  Thus, assuming the SNMP agent is in the DSLAM, the Entity MIB   should include entities for the xTU-C in the entPhysicalTable.  The   MIB's entAliasMappingTable would contain mapping information   identifying the 'ifIndex' object associated with each xTU-C.  In case   the SNMP agent is actually in the Customer Premise Equipment (CPE),   the Entity MIB should include entities for the xTU-R in the   entPhysicalTable.  In this case, the MIB's entAliasMappingTable would   contain mapping information identifying the 'ifIndex' object   associated with each xTU-R.   Also associating the relationship between the ifTable and Entity MIB,   the entPhysicalTable contains an 'entPhysicalName' object, which   approximates the semantics of the 'ifName' object from the Interface   MIB.Morgenstern, et al.

RFC 5650                     VDSL2-LINE MIB               September 20092.2.  IANA Considerations   A new ifType value (251) for Very High Speed Digital Subscriber Loop   Version 2 has been allocated for the VDSL2-LINE-MIB module, to   distinguish between ADSL lines that are managed with theRFC 2662   management model, ADSL/ADSL2 and ADSL2+ lines that are managed with   theRFC 4706 [RFC4706] management model, and VDSL2/ADSL/ADSL2 and   ADSL2+ lines that are managed with the model defined in this   document.   Also, the VDSL2-LINE-MIB module has been assigned a single object   identifier (251) for its MODULE-IDENTITY.  The IANA has allocated   this object identifier in the transmission subtree.   As performed in the past for the ADSL2-LINE-MIB module, the IANA has   ensured that the allocated ifType value is the same as the allocated   branch number in the transmission subtree.2.3.

Line Topology   A VDSL2/ADSL/ADSL2 and ADSL2+ line consists of two units: atuc or   vtuc (a central office termination unit) and atur or vtur (a remote   termination unit).  There are up to 4 channels (maximum number of   channels depends on the specific DSL technology), each carrying an   independent information flow, as shown in the figure below.Morgenstern, et al.

Counters, Interval Buckets, and Thresholds2.7.1.  Counters Managed   There are various types of counters specified in this MIB.  Each   counter refers either to the whole VDSL2/ADSL/ADSL2/ADSL2+ line, to   one of the xTU entities, or to one of the bearer channels.   o  On the whole line level      For full initializations, failed full initializations, short      initializations, and for failed short initializations, there are      event counters, current 15-minute and 0 to 96 15-minute history      bucket(s) of "interval-counters", as well as current and 0 to 30      previous 1-day interval-counter(s).  Each current 15-minute      "failed" event bucket has an associated threshold notification.   o  On the xTU level      For the LOS seconds, ES, SES, FEC seconds, and UAS, there are      event counters, current 15-minute and 0 to 96 15-minute history      bucket(s) of "interval-counters", as well as current and 0 to 30      previous 1-day interval-counter(s).  Each current 15-minute event      bucket has an associated threshold notification.Morgenstern, et al.         Standards Track                    [Page 17]

RFC 5650                     VDSL2-LINE MIB               September 2009   o  On the bearer channel level      For the coding violations (CRC anomalies) and corrected blocks      (i.e., FEC events), there are event counters, current 15-minute      and 0 to 96 15-minute history bucket(s) of "interval-counters", as      well as current and 0 to 30 previous 1-day interval-counter(s).      Each current 15-minute event bucket has an associated threshold      notification.2.7.2.  Minimum Number of Buckets   Although it is possible to support up to 96 15-minute history buckets   of "interval-counters", systems implementing this MIB module SHOULD   practically support at least 16 buckets, as specified in ITU-T   G.997.1, paragraph #7.2.7.9.   Similarly, it is possible to support up to 30 previous 1-day   "interval-counters", but systems implementing this MIB module SHOULD   support at least 1 previous day bucket.2.7.3.  Interval Buckets Initialization   There is no requirement for an agent to ensure a fixed relationship   between the start of a 15-minute interval and any wall clock;   however, some implementations may align the 15-minute intervals with   quarter hours.  Likewise, an implementation may choose to align 1-day   intervals with the start of a day.   Counters are not reset when an xTU is reinitialized, only when the   agent is reset or reinitialized (or under specific request outside   the scope of this MIB module).2.7.4.  Interval Buckets Validity   As inRFC 3593 [RFC3593] andRFC 2662 [RFC2662], in case the data for   an interval is suspect or known to be invalid, the agent MUST report   the interval as invalid.  If the current 15-minute event bucket is   determined to be invalid, the element management system SHOULD ignore   its content and the agent MUST NOT generate notifications based upon   the value of the event bucket.   A valid 15-minute event bucket SHOULD usually count the events for   exactly 15 minutes.  Similarly, a valid 1-day event bucket SHOULD   usually count the events for exactly 24 hours.  However, the   following scenarios are exceptional:Morgenstern, et al.         Standards Track                    [Page 18]

RFC 5650                     VDSL2-LINE MIB               September 2009   1) For implementations that align the 15-minute intervals with      quarter hours and the 1-day intervals with start of a day, the      management system may still start the PM process not aligned with      the wall clock.  Such a management system may wish to retrieve      even partial information for the first event buckets, rather than      declaring them all as invalid.   2) For an event bucket that suffered relatively short outages, the      management system may wish to retrieve the available PM outcomes,      rather than declaring the whole event bucket as invalid.  This is      more important for 1-day event buckets.   3) An event bucket may be shorter or longer than the formal duration      if a clock adjustment was performed during the interval.   This MIB module allows supporting the exceptional scenarios described   above by reporting the actual Monitoring Time of a monitoring   interval.  This parameter is relevant only for Valid intervals, but   is useful for these exceptional scenarios:   a) The management system MAY still declare a partial PM interval as      Valid and report the actual number of seconds the interval lasted.   b) If the interval was shortened or extended due to clock      corrections, the management system SHOULD report the actual number      of seconds the interval lasted, in addition to reporting that the      interval is Valid.2.8.  Profiles   As a managed node can handle a large number of xTUs, (e.g., hundreds   or perhaps thousands of lines), provisioning every parameter on every   xTU may become burdensome.  Moreover, most lines are provisioned   identically with the same set of parameters.  To simplify the   provisioning process, this MIB module makes use of profiles and   templates.   A configuration profile is a set of parameters that can be shared by   multiple entities.  There is a configuration profile to address line-   level provisioning and another type of profile that addresses   channel-level provisioning parameters.   A configuration template is actually a profile-of-profiles.  That is,   a template is comprised of one-line configuration profile and one or   more channel configuration profiles.  A template provides the   complete configuration of a line.  The same configuration can be   shared by multiple lines.Morgenstern, et al.         Standards Track                    [Page 19]

RFC 5650                     VDSL2-LINE MIB               September 2009   In a similar manner to the configuration profiles and templates, this   MIB module makes use of templates and profiles for specifying the   alarm thresholds associated with performance parameters.  This allows   provisioning multiple lines with the same criteria for generating   threshold crossing notifications.   The following paragraphs describe templates and profiles used in this   MIB module.2.8.1.  Configuration Profiles and Templates   o  Line Configuration Profiles - Line configuration profiles contain      line-level parameters for configuring VDSL2/ADSL/ADSL2 and ADSL2+      lines.  They are defined in the xdsl2LineConfProfTable.      The line configuration includes settings such as the specific      VDSL2/ADSL/ADSL2 or ADSL2+ modes to enable on the respective line,      power spectrum parameters, rate adaptation criteria, and SNR      margin-related parameters.  A subset of the line configuration      parameters depends upon the specific xDSL Mode allowed (i.e., does      the profile allow VDSL2, ADSL, ADSL2 and/or ADSL2+?) as well as      what annex/annexes of the standard are allowed.  This is the      reason a line profile MUST include one or more mode-specific      extensions.   o  Channel Configuration Profiles - Channel configuration profiles      contain parameters for configuring bearer channels over the VDSL2/      ADSL/ADSL2 and ADSL2+ lines.  They are sometimes considered as the      service layer configuration of the VDSL2/ADSL/ADSL2 and ADSL2+      lines.  They are defined in the xdsl2ChConfProfTable.      The channel configuration includes issues such as the desired      minimum and maximum rate on each traffic flow direction and      impulse noise protection parameters.   o  Line Configuration Templates - Line configuration templates allow      combining line configuration profiles and channel configuration      profiles into a comprehensive configuration of the VDSL2/ADSL/      ADSL2 and ADSL2+ line.  They are defined in the      xdsl2LineConfTemplateTable.      The line configuration template includes one index of a line      configuration profile and one to four indices of channel      configuration profiles.  The template also addresses the issue of      distributing the excess available data rate on each traffic flowMorgenstern, et al.         Standards Track                    [Page 20]

RFC 5650                     VDSL2-LINE MIB               September 2009      direction (i.e., the data rate left after each channel is      allocated a data rate to satisfy its minimum requested data rate)      among the various channels.2.8.2.  Alarm Configuration Profiles and Templates   o  Line Alarm Configuration Profiles - Line-level Alarm configuration      profiles contain the threshold values for Performance Monitoring      (PM) parameters, counted either on the whole line level or on an      xTU level.  Thresholds are required only for failures and      anomalies.  For example, there are thresholds for failed      initializations and LOS seconds, but not for the aggregate number      of full initializations.  These profiles are defined in the      xdsl2LineAlarmConfProfileTable.   o  Channel Alarm Configuration Profiles - Channel-level Alarm      configuration profiles contain the threshold values for PM      parameters counted on a bearer channel level.  Thresholds are      defined for two types of anomalies: corrected blocks and coding      violations.  These profiles are defined in the      xdsl2ChAlarmConfProfileTable.   o  Line Alarm Configuration Templates - Line Alarm configuration      templates allow combining line-level alarm configuration profiles      and channel-level alarm configuration profiles into a      comprehensive configuration of the PM thresholds for the VDSL2/      ADSL/ADSL2 and ADSL2+ line.  They are defined in the      xdsl2LineAlarmConfTemplateTable.      The line alarm configuration template includes one index of a      line-level alarm configuration profile and one to four indices of      channel-level alarm configuration profiles.2.8.3.  Managing Profiles and Templates   The index value for each profile and template is a locally unique,   administratively assigned name having the textual convention   'SnmpAdminString' (RFC 3411 [RFC3411]).   One or more lines may be configured to share parameters of a single   configuration template (e.g., xdsl2LConfTempTemplateName = 'silver')   by setting its xdsl2LineConfTemplate object to the value of this   template.   One or more lines may be configured to share parameters of a single   Alarm configuration template (e.g., xdsl2LAlarmConfTempTemplateName =   'silver') by setting its xdsl2LineAlarmConfTemplate object to the   value of this template.Morgenstern, et al.         Standards Track                    [Page 21]

RFC 5650                     VDSL2-LINE MIB               September 2009   Before a template can be deleted or taken out of service, it MUST be   first unreferenced from all associated lines.  Implementations MAY   also reject template modification while it is associated with any   line.   Before a profile can be deleted or taken out of service, it MUST be   first unreferenced from all associated templates.  Implementations   MAY also reject profile modification while it is referenced by any   template.   Implementations MUST provide a default profile whose name is 'DEFVAL'   for each profile and template type.  The values of the associated   parameters will be vendor-specific unless otherwise indicated in this   document.  Before a line's templates have been set, these templates   will be automatically used by setting xdsl2LineConfTemplate and   xdsl2LineAlarmConfTemplate to 'DEFVAL' where appropriate.  This   default profile name, 'DEFVAL', is considered reserved in the context   of profiles and templates defined in this MIB module.   Profiles and templates are created, assigned, and deleted dynamically   using the profile name and profile row status in each of the profile   tables.   If the implementation allows modifying a profile or template while it   is associated with a line, then such changes MUST take effect   immediately.  These changes MAY result in a restart (hard reset or   soft restart) of the units on the line.   Network Elements MAY optionally implement a fallback line   configuration template (see xdsl2LineConfFallbackTemplate).  The   fallback template will be tried if the xDSL2 line fails to operate   using the primary template.  If the xDSL2 line fails to operate using   the fallback template, then the primary template should be retried.   The xTU-C SHOULD continue to alternate between the primary and   fallback templates until one of them succeeds.2.8.4.  Managing Multiple Bearer Channels   The number of bearer channels is configured by setting the template   objects xdsl2LConfTempChan1ConfProfile,   xdsl2LConfTempChan2ConfProfile, xdsl2LConfTempChan3ConfProfile, and   xdsl2LConfTempChan4ConfProfile and then assigning that template to a   DSL line using the xdsl2LineConfTemplate object.  When the number of   bearer channels for a DSL line changes, the SNMP agent will   automatically create or destroy rows in channel-related tables   associated with that line.  For example, when a DSL line is operatingMorgenstern, et al.         Standards Track                    [Page 22]

RFC 5650                     VDSL2-LINE MIB               September 2009   with one bearer channel, there will be zero rows in channel-related   tables for channels two, three, and four.  The SNMP agent MUST create   and destroy channel-related rows as follows:   o  When the number of bearer channels for a DSL line changes to a      higher number, the SNMP agent will automatically create rows in      the xdsl2ChannelStatusTable and xdsl2PMChCurrTable tables for that      line.   o  When the number of bearer channels for a DSL line changes to a      lower number, the SNMP agent will automatically destroy rows in      the xdsl2ChannelStatusTable,      xdsl2PMChCurrTable,xdsl2PMChHist15MinTable, and      xdsl2PMChHist1DTable tables for that line.2.9.  Notifications   The ability to generate the SNMP notifications coldStart/WarmStart   (per [RFC3418]), which are per agent (e.g., per Digital Subscriber   Line Access Multiplexer, or DSLAM, in such a device), and linkUp/   linkDown (per [RFC2863]), which are per interface (i.e., VDSL2/ADSL/   ADSL2 or ADSL2+ line) is required.   A linkDown notification MAY be generated whenever any of ES, SES, CRC   anomaly, LOS, LOF, or UAS events occur.  The corresponding linkUp   notification MAY be sent when all link failure conditions are   cleared.   The notifications defined in this MIB module are for status change   (e.g., initialization failure) and for the threshold crossings   associated with the following events: full initialization failures,   short initialization failures, ES, SES, LOS seconds, UAS, FEC   seconds, FEC events, and CRC anomalies.  Each threshold has its own   enable/threshold value.  When that value is 0, the notification is   disabled.   The xdsl2LineStatusXtur and xdsl2LineStatusXtuc are bitmasks   representing all outstanding error conditions associated with the   xTU-R and xTU-C (respectively).  Note that since the xTU-R status is   obtained via the EOC, this information may be unavailable in case the   xTU-R is 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 those two   status objects are defined.Morgenstern, et al.

RFC 5650                     VDSL2-LINE MIB               September 2009   Note that there are other status parameters that refer to the xTU-R   (e.g., downstream line attenuation).  Those parameters also depend on   the availability of EOC between the central office xTU and the remote   xTU.   A threshold notification occurs whenever the corresponding current   15-minute interval error counter becomes equal to, or exceeds the   threshold value.  Only one notification SHOULD be sent per interval   per interface.  Since the current 15-minute counter is reset to 0   every 15 minutes, and 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 [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.3.

These object descriptions are based upon the specifications         for the ADSL Embedded Operations Channel (EOC) as defined         in American National Standards Institute (ANSI) T1E1.413         [T1E1.413] and International Telecommunication Union (ITU-T)         G.992.1 [G.992.1] and G.992.2 [G.992.2].         The MIB module described inRFC 4706 [RFC4706] defines         objects used for managing ADSL2 interfaces per [G.992.3]         and [G.992.4], and ADSL2+ interfaces per [G.992.5].  That MIB         is also capable of managing ADSL interfaces per [T1E1.413],         [G.992.1], and [G.992.2].         This document does not obsoleteRFC 2662 [RFC2662] orRFC 4706 [RFC4706], but rather provides a more comprehensive         management model that manages VDSL2 interfaces per G.993.2         [G.993.2] as well as ADSL, ADSL2, and ADSL2+ technologies         per T1E1.413, G.992.1, G.992.2, G.992.3, G.992.4, and         G.992.5         ([T1E1.413], [G.992.1], [G.992.2], [G.992.3], [G.992.4], and         [G.992.5], respectively).         Additionally, the management framework for VDSL2 lines         specified by the Digital Subscriber Line Forum         (DSLF) has been taken into consideration [TR-129].  That         framework is based on the ITU-T G.997.1 standard [G.997.1] and         its amendment 1 [G.997.1-Am1].         The MIB module is located in the MIB tree under MIB 2         transmission, as discussed in the MIB-2 Integration (RFC 2863         [RFC2863]) section of this document.

RFC 5650                     VDSL2-LINE MIB               September 2009       is made by modifying the xdsl2LineCmndConfBpsc object from       idle(1) to the value measure(2).       The measurement results may be very large and will not fit       into a single PDU; hence, multiple SNMP GET requests may be       required to fetch the measurement results.       Because the measurement results cannot be fetched atomically,       it is possible for a second manager to start a new measurement       before a first manager has fetched all of its results.       An SNMP manager can use this object to ensure that the       measurement results retrieved using one or more GET requests       all belong to the measurement initiated by that manager.       The following steps are suggested in order for the SNMP       manager to initiate the bits-per-subcarrier measurement:       1. Wait for xdsl2LineCmndConfBpsc value to be idle(1).       2. Perform an SNMP GET for xdsl2LineCmndConfBpscRequests.       3. Wait a short delay (4 -> 8 seconds).       4. Perform an SNMP SET on xdsl2LineCmndConfBpsc with          the value measure(2).       5. If step 4 returns an error, then go to step 1.       6. Wait for xdsl2LineCmndConfBpsc value to be idle(1).       7. Fetch measurement results using one or more GET PDUs.       8. Perform an SNMP GET for xdsl2LineCmndConfBpscRequests.       9. Compute the difference between the two values of          xdsl2LineCmndConfBpscRequests.

RFC 5650                     VDSL2-LINE MIB               September 2009   certain differences betweenRFC 2662 [RFC2662] and this MIB module,   including the following aspects:   o  Though the configuration templates/profiles allow referring to 1-4      bearer channels, ADSL links are limited to two channels at most.   o  Though the channel configuration profile allows higher data rates,      ADSL links are limited to downstream/upstream data rate as assumed      inRFC 2662 [RFC2662].   o  The Impulse Noise Protection (INP) configuration parameters are      given by minimum protection and maximum delay parameters.   o  The line configuration profile includes a sub-table that addresses      mode-specific parameters.  For ADSL links, the management      application SHOULD create a row in that table for the ADSL modes      only.   o  The line configuration profile includes parameters that are      irrelevant for ADSL links.  Similarly, many status parameters in      the MIB are irrelevant for certain ADSL modes.  Therefore, it is      advised to consult with ITU G.997.1 standard [G.997.1] regarding      the scope and relevance of each parameter in this MIB.5.  Security Considerations   There are a number of management objects defined in this MIB module   with a MAX-ACCESS clause of read-write and/or read-create.

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:   o  xdsl2LineInventoryTable      Access to these objects would allow an intruder to obtain      information about which vendor's equipment is in use on the      network.

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).   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 only to those objects whose   principals (users) have legitimate rights to indeed GET or SET   (change/create/delete) them.6.
