Abstract This document defines a standard SNMP MIB for ADSL lines based on the ADSL Forum standard data model [9]. The model assumed by this MIB is that the SNMP agent's perspective is from the ATU-C side which acts as a proxy for the ATU-R. Each MIB instance includes information for both ends of a single line, i.e., both the ATU-C and ATU-R. It should be noted that much of the content for the first version of this document came from work completed by the ADSL Forum's Network Expires June 1999 [Page 1] INTERNET-DRAFT ADSL Line MIB October 30, 1998 Management working group and documented in ADSL Forum TR-006 "SNMP- based ADSL Line MIB"[9]. See Acknowledgement Section for a list of individuals involved with this effort. 3. The SNMP Network Management Framework The SNMP Management Framework presently consists of five major components: o An overall architecture, described in RFC 2271 [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 RFC 1155 [14], RFC 1212 [15] and RFC 1215 [16]. The second version, called SMIv2, is described in RFC 1902 [1], RFC 1903 [2] and RFC 1904 [17]. o Message protocols for transferring management information. The first version of the SNMP message protocol is called SNMPv1 and described in RFC 1157 [7]. A second version of the SNMP message protocol, which is not an Internet standards track protocol, is called SNMPv2c and described in RFC 1901 [18] and RFC 1906 [19]. The third version of the message protocol is called SNMPv3 and described in RFC 1906 [19], RFC 2272 [20] and RFC 2274 [21]. o Protocol operations for accessing management information. The first set of protocol operations and associated PDU formats is described in RFC 1157 [7]. A second set of protocol operations and associated PDU formats is described in RFC 1905 [8]. o A set of fundamental applications described in RFC 2273 [22] and the view-based access control mechanism described in RFC 2275 [23]. 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 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 Expires June 1999 [Page 2] INTERNET-DRAFT ADSL Line MIB October 30, 1998 descriptions in SMIv1 during the translation process. However, this loss of machine readable information is not considered to change the semantics of the MIB. 4. 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 extented 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. 5. Introduction This document describes an ADSL Line MIB which is intended to work within the SNMP Network Management Framework (section 3). All MIB definitions are backward compatible for SNMPv1 implementation. The MIB definitions are attached. The MIB will eventually be located in the MIB tree under mib-2 transmission, further discussed in section 6 of this document. 6. 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". 6.1 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 Expires June 1999 [Page 3] INTERNET-DRAFT ADSL Line MIB October 30, 1998 . . . adslInterleave(124), -- ADSL Interleaved Channel adslFast(125), -- ADSL Fast Channel . . . } Interfaces of each of these types are modeled by this document. Pending approval of the IANA, under the advisement from IESG, adslMIB will be used as the root of this MIB and will be assigned to the value { transmission 94 }. 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 in section 7.4 Profiles. 6.1.1 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 Model Expires June 1999 [Page 4] INTERNET-DRAFT ADSL Line MIB October 30, 1998 6.1.2 Use of IF-MIB (Interface MIB RFC 2233) [5] The following attributes are part of the neccesary ifGeneralInformationGroup object group specified in RFC 2233 [5], and are not duplicated in the ADSL MIB. Keep in mind that these objects apply to the agent's view of the line. ifTable Object Use for ADSL ================================================================== ifIndex Interface index. ifDescr See interfaces MIB [5] ifType physical - adsl(94) fast - adslFast(125) interleaved - adslInterleave(124) ifSpeed Transmit rate from the perpective of the agent. physical - line rate fast - channel rate interleaved - channel rate ifPhysAddress This object should have an octet string with zero length. ifAdminStatus See interfaces MIB [5] ifOperStatus See interfaces MIB [5] Supplemented by adslAturCurrStatus and adslAturCurrStatus ifLastChange See interfaces MIB [5] ifName See interfaces MIB [5] ifLinkUpDownTrapEnable See interfaces MIB [5] Default set as follows: physical - enabled(1) fast - disabled(2) interleaved - disabled(2) ifHighSpeed Speed of line in Mega-bits per second (ifSpeed/1,000,000) Expires June 1999 [Page 5] INTERNET-DRAFT ADSL Line MIB October 30, 1998 ifConnectorPresent See interfaces MIB [5] Default set as follows: physical - true(1) fast - false(2) interleaved - false(2) ifAlias See interfaces MIB [5] ifTableLastChange See interfaces MIB [5] ================================================================== Figure 2: Use of ifTable Objects: ifGeneralInformationGroup Use of the ifStackTable to associate the entries for physical, fast, interleaved channels, and higher layers (e.g., ATM) is shown below in figure 3. Use of ifStackTable is necessary, because configuration information is stored in profile tables associated with the physical-layer ifEntry only. The channels' ifEntrys need the ifStackTable to find their associated physical-layer entry and thus their configuration parameters. (See Profile section, 7.4). ______ (ifEntry=j) ______ | | fast channel | | | |________________________| | | | and/or | | | | | | | | (ifEntry=k) | | | | interleaved channel | | | |________________________| | | ATUC | | ATUR | | | | | | | (ifEntry=i) | | | | physical | | | |________________________| | |______| |______| Figure 3: Use of ifStackTable (part 1) The ifStackTable is then used to show the relationships between the various ADSL interfaces, as illustrated below in figure 4.

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 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. 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. 7. Conventions used in the MIB 7.1 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, adslAtucChanConfMaxTxRate defines the "downstream" rate, while adslAturChanConfMaxTxRate defines the "upstream" rate for a Expires June 1999 [Page 7] INTERNET-DRAFT ADSL Line MIB October 30, 1998 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. 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). 7.2 Structure The MIB has multiple parallel tables. There are tables for: o line - common attributes Expires June 1999 [Page 8] INTERNET-DRAFT ADSL Line MIB October 30, 1998 o atuc and atur status 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. Finally, there are separate LCS tables, also for each end. These are currently stubs. These will each be separate MIB 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.

The Manager may select the type of channel to be used. Depending on which operation configuration exists, some or all ADSL MIB tables could be supported, as shown in below. See Conformance Statements for more information on which objects are mandatory.

See Profile Section of this document for implementation details such as profile creation, assignment, and indexing. 7.3 Counters, Interval Buckets and Thresholds For physical-level ES, Los, Lof, Lol, Lpr and line initialization attempts, there are event counters, current 15-minute and one (up to 96) 15-minute history bucket(s) of "interval-counters", as well as current and previous 1-day interval-counters. 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. In all cases, the sum of the corresponding 15-minute interval timers for the current day should equal the current 1-day timers. However, in most cases, this will not be the sum of all 96 intervals, as they represent a rolling set of data. 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. Separate tables are provided for the 96 interval-counters. They are Expires June 1999 [Page 10] INTERNET-DRAFT ADSL Line MIB October 30, 1998 indexed by {ifIndex, AdslAtu*IntervalNumber}. Every physical layer object with a 15 minute current bucket also has a 15-min threshold trap. Counters are not reset when an ATU-C is reinitialized, only when the agent is reset or reinitialized (or under specific request outside the scope of this MIB). 7.4 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. This concept is similar to the one used in ATM MIB (RFC 1695[24]) to define ATM traffic descriptor sets. 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. 7.4.1 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 arbitrary integer in the range 1..N, where N is the maximum number of profiles supported by the equipment and is implementation specific. One or more ADSL lines may be configured to share parameters of a single profile (say adslLineConfProfileIndex = `n') by setting their adslLineConfProfile objects to the value of profile's index (n). If a change is made to Profile-n, all lines that refer to it will be re-configured to the changed parameters. The next figure shows an example of how this mode can be implemented. In the example, ADSL lines `1' and `x' share the configuration in Profile-n, while line `2' uses Profile-1. Please note that all three entries for each ADSL line, the physical layer, fast channel, and Expires June 1999 [Page 11] INTERNET-DRAFT ADSL Line MIB October 30, 1998 interleaved channel are represented by "i", "j", and "k". However, only the physical-layer entry "i" contains an adslLineTable entry, so only those entries contain pointers to the adslConfProfileEntry. The ifStackTable (see rfc2233 [5]) must be used to link the channel entries to the corresponding physical layer entry to get the channel's configuration parameters. ADSL ifIndex ifTable Configuration Line Profile Table __________________________________________________________________ 1 i1 ADSL Line -- ---> Profile 1 j1 Fast Chan | | k1 Int Chan | | | ^ v | Profile 2 2 i2 ADSL Line ------->---- j2 Fast Chan | k2 Int Chan | | | | v x ix ADSL Line ------>-------> Profile X jx Fast Chan ----------------> kx Int Chan __________________________________________________________________ Figure 7: Use of Profiles in MODE-I The same is true for the alarm profile (not shown), although there is no requirement that its index (call it "m") be the same as the configuration profile. In this mode, profiles are allocated and deleted dynamically, and six objects: adslLineConfProfile, adslLineConfProfileIndexNext, adslLineConfProfileRowStatus, adslLineAlarmProfile, adslLineAlarmConfProfileIndexNext, and adslLineAlarmConfProfileRowStatus are all used in conjunction with profiles. Expires June 1999 [Page 12] INTERNET-DRAFT ADSL Line MIB October 30, 1998 7.4.2 MODE-II : Static Profiles Implementations with this mode will automatically create a profile one-for-one with each ADSL line physical entry with the profileIndex being the same as the ifIndex of the corresponding ADSL line entry ("ix"). In this mode, the Agent will not allow a Manager to create/delete profiles in this mode. Therefore, the adslLineConfProfile, adslLineConfProfileIndexNext, adslLineConfProfileRowStatus, adslLineAlarmProfile, adslLineAlarmConfProfileIndexNext, and adslLineAlarmConfProfileRowStatus objects have minimal value in this mode as each line has a unique, fixed profile that is not shared with other lines. These six variables are read-only in this mode. The figure below shows an example of this mode. In the example, ADSL lines `1', `2', and `x' each have their own profiles. ADSL ifIndex ifTable Configuration Line Profile Table __________________________________________________________________ 1 i1 ADSL Line ------------> Profile 1 j1 Fast Chan k1 Int Chan 2 i2 ADSL Line ------------> Profile 2 j2 Fast Chan k2 Int Chan x ix ADSL Line ------------> Profile X jx Fast Chan kx Int Chan __________________________________________________________________ Figure 8: User Profiles in MODE II 7.5 Traps These SNMP traps are required: coldStart / warmStart (per [6]) -- which are per agent (e.g., per DSLAM in such a device), and linkUp / linkDown (per [5]) -- which are per interface (i.e., ADSL line). Note: RFC 2233 [5] recommends that linkUp / linkDown only be used at a physical layer ifEntry, as discussed above. Expires June 1999 [Page 13] INTERNET-DRAFT ADSL Line MIB October 30, 1998 A linkDown trap is generated whenever any of Lof, Los, Lol, or Lpr 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 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 co-resides with the ATU-C, adslAturCurrStatus may be incomplete. For example, when there are errors on the line, the ATU-R may not be able to correctly report this condition. Therefore, not all conditions are included in adslAturCurrStatus. A threshold trap occurs whenever the corresponding current 15-minute interval error counter becomes equal to the threshold value. 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, 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 ThreshRateDown No trap is sent on initialization. Expires June 1999 [Page 14] INTERNET-DRAFT ADSL Line MIB October 30, 1998 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 exceeds the threshold. 8.

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 7.4) 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, Expires June 1999 [Page 95] INTERNET-DRAFT ADSL Line MIB October 30, 1998 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 Model RFC 2274 [21] and the View-based Access Control Model RFC 2275 [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. 13. Authors' Addresses Gregory Bathrick AG Communication Systems 2500 W Utopia Rd.
