The ADSL standard describes   ATU-C and ATU-R as two sides of the ADSL line.  This MIB covers both   ATU-C and ATU-R agent's perspectives.  Each instance defined in the   MIB represents a single ADSL line.Bathrick & Ly               Standards Track                     [Page 1]

RFC 2662                     ADSL Line MIB                   August 1999   It should be noted that the ADSL Forum Network Management Working   Group provided input towards the content of this document.  See the   Acknowledgement Section for a list of individuals who made this   document possible.2.  The SNMP Network Management Framework   The SNMP Management Framework presently consists of five major   components:   o  An overall architecture, described inRFC 2571 [13].   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 [14], STD 16,RFC 1212 [15] andRFC 1215 [16].  The      second version, called SMIv2, is described in STD 58,RFC 2578      [1], STD 58,RFC 2579 [2] and STD 58,RFC 2580 [17].   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 [7].  A second version of the SNMP      message protocol, which is not an Internet standards track      protocol, is called SNMPv2c and described inRFC 1901 [18] andRFC1906 [19].  The third version of the message protocol is called      SNMPv3 and described inRFC 1906 [19],RFC 2572 [20] andRFC 2574      [21].   o  Protocol operations for accessing management information.  The      first set of protocol operations and associated PDU formats is      described in STD 15,RFC 1157 [7].  A second set of protocol      operations and associated PDU formats is described inRFC 1905      [8].   o  A set of fundamental applications described inRFC 2573 [22] and      the view-based access control mechanism described inRFC 2575      [23].   This document 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 (e.g., 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.Bathrick & Ly               Standards Track                     [Page 2]

RFC 2662                     ADSL Line MIB                   August 19993.  Object Definitions   Managed objects are accessed via a virtual information store, termed   the Management Information Base or MIB.  Objects in the MIB are   defined using the extended subset of Abstract Syntax Notation One   (ASN.1) defined in the SMI.  In particular, each object type is named   by an OBJECT IDENTIFIER, an administratively assigned name.  The   object type together with an object instance serves to uniquely   identify a specific instantiation of the object.  For human   convenience, we often use a textual string, termed the descriptor, to   also refer to the object type.4.  Relationship of the ADSL LINE MIB with standard MIBs   This section outlines the relationship of ADSL Line MIB with other   MIBs described in RFCs and in their various degrees of   "standardization".4.1  Use of the IfTable   The ADSL LINE MIB specifies the detailed attributes of a data   interface.  As such, it needs to integrate with IF-MIB [5].  The IANA   has assigned the following ifType(s) relative to ADSL:       IANAifType ::= TEXTUAL-CONVENTION           . . .       SYNTAX INTEGER {                . . .           adsl(94),    -- Asymmetric Digital Subscriber Loop                . . .           adslInterleave(124),    -- ADSL Interleaved Channel           adslFast(125),          -- ADSL Fast Channel                . . .          }   Interfaces of each of these types are modeled by this document.  Most   MIB tables in this document represent information of one of these   interface types and are indexed by ifIndex.  Remaining are `profile'   tables which may be accessed by the profileIndex.  This is explained   in more detail insection 5.4 Profiles.Bathrick & Ly               Standards Track                     [Page 3]

RFC 2662                     ADSL Line MIB                   August 19994.1.1  ADSL Interface Types   As shown below, three ADSL interface types are defined in this   document, namely physical, interleaved channel, and fast channel.   The physical interface represents characteristics of the physical   media associated with both the ATUC and ATUR.  The interleaved and   fast channel interface represent the characteristics of the two types   of ADSL channels.   For each ADSL Line, a physical interface always exists.   Depending   on which ADSL operational configuration is present (as listed in   Figure 5), the channel interfaces (fast or interleaved) may or may   not exist.               ______                      ______              |      |____________________|      |              | ATUC |                    | ATUR |              |      |____________________|      |              |______|                    |______|                 | <----- physical --------> |                 | <--- fast channel ------> |                 | <- interleaved channel -> |                      Figure 1: ADSL Model4.1.2  Use of IF-MIB(Interface MIBRFC 2233) [5]   The following attributes are part of the required   ifGeneralInformationGroup object group specified inRFC 2233 [5], and   are not duplicated in the ADSL MIB.

RFC 2662                     ADSL Line MIB                   August 19994.2  Relationship withRFC 2037 [25]   Implementation of the Entity MIB [25] is optional.  It in no way   alters the information required in the adslLineMib, 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   adslLineMib.   If ATU-C agent is implemented, the Entity MIB should include entities   for the ATU-C in the entPhysicalTable.  The MIB's   entAliasMappingTable would contain mapping information identifying   the 'ifIndex' object associated with each ATU-C.  However, if ATU-R   agent is implemented, the Entity MIB should include entities for the   ATU-R in the entPhysicalTable.  In this case, the MIB's   entAliasMappingTable would  contain mapping information identifying   the 'ifIndex' object associated with each ATU-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.5.  Conventions used in the MIB5.1  Naming Conventions   A. Atuc/Atur are used for the ATU-C and ATU-R.  In other RFCs, these      are sometimes referred to as the Near End (Ne) and Far End (Fe)      respectively, but not in this document.   B. The terms, "transmit" and "receive", are from the perspective of      the corresponding table's end of the line.  For example, in the      case of Fast channels, adslAtucChanConfFastMaxTxRate defines the      "downstream" rate, while adslAturChanConfFastMaxTxRate defines the      "upstream" rate for a particular channel.   C. There are two possible channels: fast, and interleaved.  None, one      or both may be implemented on a particular ADSL Line.  Figure 5      illustrates all possible operational configurations.Bathrick & Ly               Standards Track                     [Page 7]

RFC 2662                     ADSL Line MIB                   August 1999   D. Lof, Lol, Los, Lpr mean Loss of Framing, Link, Signal, and Power,      respectively.  Lpr is used by T1E1, so it is used for consistency      (rather than Lop).      A Loss of Link condition is declared at the ATU-C if a Loss of      Signal is not preceded by a `dying-gasp' message from the ATU-R.      Note that Loss of Link is only supported by the ATU-C.   E. ES means errored second. An Errored Second is any second      containing one or more CRC anomaly, or one or more Los(s) or      Severely Errored Frame (Sef) defect(s).   F. A "block" is a physical-layer `data buffer' over which CRCs are      calculated.  For example, in DMT, the block is defined as the ADSL      superframe.  The block duration is 250 micro-seconds so the block      length in bytes, as defined in adslAtu*ChanCrcBlockLength, varies      with data rate.  See Line Code Specific MIBs [11] [12] for more      line code specific information.   G. Atn means Attenuation, Psd is Power Spectral Density and Snr is      Signal to Noise Ratio.   H. LCS means line code specific, e.g.,      o DMT = Discrete MultiTone      o CAP = Carrierless Amplitude and Phase modulation and      o QAM = Quadrature Amplitude Modulation   I. Vendor (in the Inventory objects) refers to the manufacturer of      the ATU-C or ATU-R assembly, not the modem chip vendor. When in      doubt, use the manufacturer of the smallest field replaceable unit      (e.g., stand-alone modem box, plug-in board).   J. RADSL - Rate Adaptive Asymmetric Digital Subscriber Loop5.2  Structure   The MIB has multiple parallel tables.  There are tables for:      o line -  common attributes      o atuc and atur statusBathrick & Ly               Standards Track                     [Page 8]

RFC 2662                     ADSL Line MIB                   August 1999      o atuc and atur performance         - Current and up to 96 buckets of 15 min performance history         - Current and Previous 1-day bucket performance history      o profiles - configuration parameters and alarm parameters   There are separate tables for Physical and Channel layers.  Since   their attributes are similar, only one set of "channel" tables are   defined to be used for both fast and interleaved channels. The   corresponding ifType gives the proper interpretation for that   ifEntry.   It is intented that Line Code Specific MIBs be located under   adslLCSMib.  These MIBs will be defined in separate modules.   There could have been fewer tables by combining the ATU-C and ATU-R   information into shared tables. However, the tables are more easily   read when there are two identical sets of data.   The figure below lists the five possible ADSL operational   configurations. (indicated by the value of the adslLineType).  In all   configurations, the physical line interface entry will exist.   However, the existence of the ADSL channel varies in each case, as   shown below.

See Profile Section of this   document for implementation details such as profile creation,   assignment, and indexing.5.2.1 Structure of Conformance Groups   The MIB is organized to cover both ends of the ADSL line, ATU-C and   ATU-R.  Objects defined can be categorized into two groups:  the   ATU-C group which provides objects that are supported by ATU-C agents   and the ATU-R group which provides objects that are supported by   ATU-R agents.  These two groups are defined by the conformance   section of the MIB.

Each physical-layer   current 15-minute event bucket has threshold trap.   At the channel level, there are counters for total received blocks,   received-and-corrected blocks, received-but-uncorrectable blocks, and   transmitted blocks. There are the same set of 15-minute and 1-day   buckets as at the physical-layer.   There is no requirement for an agent to ensure fixed relationship   between the start of 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 start of a day.   Separate tables are provided for the 96 interval-counters. They are   indexed by {ifIndex, AdslAtu*IntervalNumber}.   Counters are not reset when an ATU-C or ATU-R is reinitialized, only   when the agent is reset or reinitialized (or under specific request   outside the scope of this MIB).   The 15-minute event counters are of type PerfCurrentCount and   PerfIntervalCount.  The 1-day event counters are of type   AdslPerfCurrDayCount and AdslPerfPrevDayCount. Both 15-minute and 1-   day time elapsed counters are of type AdslPerfTimeElapsed.Bathrick & Ly               Standards Track                    [Page 12]

RFC 2662                     ADSL Line MIB                   August 19995.4  Profiles   As a managed node can handle a large number of ATU-Cs (e.g., hundreds   or perhaps thousands of ADSL lines), provisioning every parameter on   every ATU-C may become burdensome.  In response, two MIB tables have   been created to define ADSL equipment configuration data profiles, as   well as a mechanism to associate the equipment to these profiles.   Profile tables may be implemented in one of two ways, but not   simultaneously:      o  MODE-I: Dynamic Profiles - one profile shared by one or         multiple ADSL lines.      o  MODE-II: Static Profiles - one profile per ADSL physical line         always.5.4.1  MODE-I : Dynamic Profiles   Implementations using this mode will enable the manager to   dynamically create and delete profiles as needed.  The index of the   profile is an locally-unique administratively assigned name for the   profile having the textual convention `SnmpAdminString' (RFC2571   [13]).   One or more ADSL lines may be configured to share parameters of a   single profile (e.g., adslLineConfProfileName = `silver') by setting   its adslLineConfProfile objects to the index value of this profile.   If a change is made to the profile, all lines that refer to it will   be re-configured to the changed parameters.  Before a profile can be   deleted or taken out of service it must be first unreferenced from   all associated lines.   This figure below shows an example of how this mode can be   implemented.  In the example, ADSL lines `1' and `x' share the   configuration of the `silver' profile, while line `2' uses the   `platinum' profile.  The `gold' profile has no lines associated with   it.Bathrick & Ly               Standards Track                    [Page 13]

Only the physical-layer entry `i'   contains an adslLineTable entry, therefore only those entries contain   pointers to the adslLineConfProfileTable.  The ifStackTable (seerfc2233 [5]) can be used to link the channel entries to the   corresponding physical-layer entry to get the channel's configuration   parameters.  See figure 4 for use of the ifStackTable.   The same characteristics and mechanisms are present for the alarm   profile type. There is no requirement that its index be the same as   the configuration profile.   Implementations of this mode, must provide a default profile whose   name is `DEFVAL' for each profile type: Configuration and Alarm.  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   adslLineConfProfile and adslLineAlarmConfProfile to `DEFVAL'.Bathrick & Ly               Standards Track                    [Page 14]

RFC 2662                     ADSL Line MIB                   August 1999   In this mode, profiles are created, assigned, and deleted dynamically   using these four objects: adslLineConfProfile,   adslLineConfProfileRowStatus, adslLineAlarmConfProfile,  and   adslLineAlarmConfProfileRowStatus.5.4.2  MODE-II : Static Profiles   Implementations with this mode will automatically create a profile   one-for-one with each ADSL line physical entry.  The name of this   profile is a system generated read-only object whose value is   equivalent to the index of the physical line.  The Agent will not   allow a Manager to create/delete profiles in this mode.  Therefore,   adslLineConfProfile, adslLineConfProfileRowStatus,   adslLineAlarmConfProfile, and adslLineAlarmConfProfileRowStatus   objects have minimal value in this mode and are read-only.   The figure below shows an example of this mode. In the example, ADSL   lines `1', `2', and `x' each have their own profiles.

Note:RFC 2233 [5] recommends that linkUp / linkDown only be used at   a physical-layer ifEntry, as discussed above.Bathrick & Ly               Standards Track                    [Page 15]

RFC 2662                     ADSL Line MIB                   August 1999   A linkDown trap is generated whenever any of Lof, Los, Lol, Loss of   Signal Quality, or Lpr events occurs.  At this operational point, a   manager can use adslAtu*CurrStatus for additional detailed   information. The corresponding linkUp trap is sent when all link   failure conditions are cleared.   The traps defined in this MIB are for initialization failure, rate   change, and for the threshold crossings associated with the following   events: Lofs, Lols, Loss, Lprs, and ESs.  Each threshold has its own   enable/threshold value. When that value is 0, the trap is disabled.   The current status objects (adslAtu*CurrStatus) indicate, through a   bitmask, all outstanding error conditions or that the line is   operational.  Note that each object claims to represent the status of   the modem at that end of the line.  However, since the SNMP agent   likely co-resides with only one end of the line, the corresponding   far-end current status object may be incomplete. For example, when   there are errors on the line, the far-end ATU may not be able to   correctly report this condition. Therefore, not all conditions are   included in its current status.   A threshold trap occurs whenever the corresponding current 15-minute   interval error counter becomes equal and/or exceeds to the threshold   value.  One trap will be sent per interval per interface. Since the   current 15-minute counter are reset to 0 every 15 minutes, if the   condition persists, the trap may recur as often as every 15 minutes.   For example, to get a trap whenever a "loss of" event occurs (but at   most once every 15 minutes), set the corresponding "Thresh15Min" to   1.  The agent will generate a trap when the event originally occurs.   Note that the NMS will get a linkDown trap, as well, if enabled.  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 trap   will be sent again.   The rate change trap is invoked when the transmit rate on a channel   either increases by adsl(x)Thresh(y)RateUp or decreases by   adsl(x)Thresh(y)RateDown. The trap is per direction:(x) == Atuc or   Atur, and per channel: (y) == Fast or Interleave. In other words, the   trap is sent whenever the rate changes in either direction on either   channel and:                CurrTxRate >= PrevTxRate plus ThreshRateUp                                    or               CurrTxRate <= PrevTxRate minus ThreshRateDownBathrick & Ly               Standards Track                    [Page 16]

RFC 2662                     ADSL Line MIB                   August 1999   No trap is sent on initialization.   It can be disabled by setting the Up (and/or) Down threshold rates to   0.   The PrevTxRate object is set to the current value at initialization   and when a trap is sent.  Thus rate changes are cumulative until the   total change reaches the threshold.6.

RFC 2662                     ADSL Line MIB                   August 1999       an entry in an ifTable which may include multiple modem lines.       An agent may reside at either end of the ADSL line however the       MIB is designed to require no management communication between       them beyond that inherent in the low-level ADSL line protocol.       The agent may monitor and control this protocol for its needs.       ADSL 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 an ADSL       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 adsl(94), fast(125), and       interleaved(124), respectively. The ifStackTable is used to       represent the relationship between the entries.

RFC 2662                     ADSL Line MIB                   August 199910.  Security Considerations   1) Blocking unauthorized access to the ADSL MIB via the element   management system is outside the scope of this document. It should be   noted that access to the MIB permits the unauthorized entity to   modify the profiles (sect 6.4) such that both subscriber service and   network operations can be interfered with. Subscriber service can be   altered by modifying any of a number of service characteristics such   as rate partitioning and maximum transmission rates. Network   operations can be impacted by modification of trap thresholds such as   SNR margins.   2) There are a number of managed objects in this MIB that may be   considered to contain sensitive information.  In particular, the   certain objects may be considered sensitive in many environments,   since it would allow an intruder to obtain information about which   vendor's equipment is in use on the network.  Therefore, it may be   important in some environments to control read access to these   objects and possibly to even encrypt the values of these object when   sending them over the network via SNMP.  Not all versions of SNMP   provide features for such a secure environment.   SNMPv1 by itself is such an insecure 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 (read) the objects in this MIB.  It is recommended   that the implementors consider the security features as provided by   the SNMPv3 framework.  Specifically, the use of the User-based   Security ModelRFC 2574 [21] and the View-based Access Control ModelRFC 2575 [23] is recommended.   It is then a customer/user responsibility to ensure that the SNMP   entity giving access to an instance of this MIB, is properly   configured to give access to those objects only to those principals   (users) that have legitimate rights to access them.   3) ADSL layer connectivity from the ATU-R will permit the subscriber   to manipulate both the ADSL link directly and the AOC/EOC channels   for their own loop.  For example,  unchecked or unfiltered   fluctuations initiated by the subscriber could generate sufficient   traps to potentially overwhelm either the management interface to the   network or the element manager.  Other attacks affecting the ATU-R   portions of the MIB may also be possible.Bathrick & Ly               Standards Track                   [Page 113]
