The Internet-Standard Management Framework For a detailed overview of the documents that describe the current Internet-Standard Management Framework, please refer to Section 7 of RFC 3410 [RFC3410]. Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. MIB objects are generally accessed through the Simple Network Management Protocol (SNMP). Objects in the MIB are defined using the mechanisms defined in the Structure of Management Information (SMI). This memo specifies a MIB module that is compliant to the SMIv2, which is described in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580 [RFC2580]. The key words "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 [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 HDSL2/SHDSL lines. Sikes, et al. Standards Track [Page 2]
RFC 4319 HDSL2-SHDSL-LINE-MIB December 2005 The MIB module described in RFC 3276 [RFC3276] describes objects used for managing High Bit-Rate DSL - 2nd generation (HDSL2) [T1E1.4] and Single-Pair High-Speed Digital Subscriber Line (SHDSL) interfaces [G.991.2]. These object descriptions are based upon the specifications for the HDSL2 and SHDSL Embedded Operations Channel (EOC), as defined in the American National Standards Institute (ANSI) T1E1.4/2000-006 [T1E1.4] and International Telecommunication Union (ITU) G.991.2 [G.991.2]. This document obsoletes RFC 3276 [RFC3276], which supports G.shdsl in that the MIB module described herein supports G.shdsl.bis as described in the G.991.2 [G.991.2]. In addition, objects have been added to improve the management of SHDSL lines. 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. 2.1. Relationship to Other MIBs This section outlines the relationship of this MIB module with other MIB modules described in RFCs. Specifically, the IF-MIB, as presented in RFC 2863 [RFC2863], is discussed. 2.1.1. General IF-MIB Integration (RFC 2863) The HDSL2/SHDSL line MIB specifies the detailed attributes of a data interface. As such, it needs to integrate with RFC 2863 [RFC2863]. The IANA has assigned the following ifTypes to HDSL2 and SHDSL: IANAifType ::= TEXTUAL-CONVENTION ... SYNTAX INTEGER { ... hdsl2 (168), -- High Bit-Rate DSL, 2nd generation shdsl (169), -- Multirate HDSL2 ... } Note that the ifFixedLengthGroup from RFC 2863 [RFC2863] MUST be supported and that the ifRcvAddressGroup does not apply to this MIB module. 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 Sikes, et al. Standards Track [Page 3]
RFC 4319 HDSL2-SHDSL-LINE-MIB December 2005 this MIB module, those table entries indexed by ifIndex MUST be persistent. The following attributes are part of the mandatory ifGeneralInformationGroup in RFC 2863 [RFC2863] and are not duplicated in the HDSL2/SHDSL line MIB. =================================================================== ifIndex Interface index. ifDescr See interfaces MIB [RFC2863]. ifType hdsl2(168) or shdsl(169). ifSpeed Set as appropriate. (This is fixed at 1552000 for HDSL2 lines) ifPhysAddress This object MUST have an octet string with zero length. ifAdminStatus See interfaces MIB [RFC2863]. ifOperStatus See interfaces MIB [RFC2863]. ifLastChange See interfaces MIB [RFC2863]. ifName See interfaces MIB [RFC2863]. ifAlias See interfaces MIB [RFC2863]. ifLinkUpDownTrapEnable Default to enabled(1). ifHighSpeed Set as appropriate. (For HDSL2 lines, this is fixed at 2) ifConnectorPresent Set as appropriate. =================================================================== Figure 1: Use of ifTable Objects 2.2. IANA Considerations The HDSL2-SHDSL-LINE-MIB module requires the allocation of a single object identifier for its MODULE-IDENTITY. The IANA has allocated this object identifier in the transmission subtree (48), defined in the SNMPv2-SMI MIB module. Sikes, et al. Standards Track [Page 4]
RFC 4319 HDSL2-SHDSL-LINE-MIB December 2005 The assignment was in fact done when RFC 3276 was published, and this revision of the RFC does not require any new action from IANA. 2.3. Conventions Used in the MIB Module 2.3.1. Naming Conventions A. xtuC refers to a central site terminal unit; H2TU-C for HDSL2, or STU-C for SHDSL.

Line Topology An HDSL2/SHDSL line consists of a minimum of two units: xtuC (the central termination unit) and an xtuR (the remote termination unit). The line may optionally support up to 8 repeater/regenerator units (xru) as shown in the figure below. Sikes, et al. Standards Track [Page 9]

Counters, Interval Buckets, and Thresholds For SNR Margin, Loop Attenuation, ES, SES, CRC anomalies, LOSW, 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. Unlike RFC 3593 [RFC3593] and RFC 2662 [RFC2662], there is no representation in the MIB module for invalid buckets. In those cases where the data 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 the value of the event bucket MUST NOT be generated. Not reporting an interval will result in holes in the associated table. For example, the table hdsl2Shdsl15MinIntervalTable is indexed by { ifIndex, hdsl2ShdslInvIndex, hdsl2ShdslEndpointSide, hdsl2ShdslEndpointWirePair, hdsl2Shdsl15MinIntervalNumber}. If interval 12 is determined to be invalid but intervals 11 and 13 are valid, a Get Next operation on the indices .1.1.1.1.11 would return indices .1.1.1.1.13. 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 Sikes, et al. Standards Track [Page 10]
RFC 4319 HDSL2-SHDSL-LINE-MIB December 2005 quarter hours. Likewise, an implementation may choose to align 1-day intervals with the start of a day. Counters are not reset when an xU is reinitialized, only when the agent is reset or reinitialized (or under specific request outside the scope of this MIB module). 2.7. Profiles As a managed node can handle a large number of xUs (e.g., hundreds or perhaps thousands of lines), provisioning every parameter on every xU 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. 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 module: o Span Configuration Profiles - Span configuration profiles contain parameters for configuring HDSL2/SHDSL spans. They are defined in the hdsl2ShdslSpanConfProfileTable. Since span configuration parameters are only applicable for SHDSL, the support for span configuration profiles is optional for HDSL2 interfaces. Note that the configuration of the span dictates the behavior for each individual segment endpoint in the span. If a different configuration is provisioned for any given segment endpoint within the span, the new configuration for this segment endpoint will override the span configuration for this segment endpoint only. o Segment Endpoint Alarm Configuration Profiles - These profiles contain parameters for configuring alarm thresholds for HDSL2/ SHDSL segment endpoints. These profiles are defined in the hdsl2ShdslEndpointAlarmConfProfileTable. The index value for this profile is a locally-unique administratively-assigned name for the profile having the textual convention 'SnmpAdminString' (RFC 3411 [RFC3411]). One or more lines may be configured to share parameters of a single profile (e.g., hdsl2ShdslEndpointAlarmConfProfile = 'silver') by setting its hdsl2ShdslEndpointAlarmConfProfile 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. Sikes, et al. Standards Track [Page 11]
RFC 4319 HDSL2-SHDSL-LINE-MIB December 2005 Implementations MUST provide a default profile whose name is 'DEFVAL' 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 hdsl2ShdslEndpointAlarmConfProfile and hdsl2ShdslSpanConfProfile to 'DEFVAL' where appropriate. This default profile name, 'DEFVAL', is considered reserved in the context of profiles defined in this MIB module. 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. 2.8. 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., HDSL2/SHDSL line) is required. A linkDown notification MAY be generated whenever any ES, SES, CRC anomaly, LOSW, or UAS event occurs. The corresponding linkUp notification MAY be sent when all link failure conditions are cleared. The notifications defined in this MIB module are for initialization failure and for the threshold crossings associated with the following events: ES, SES, CRC anomaly, LOSW, and UAS. Each threshold has its own enable/threshold value. When that value is 0, the notification is disabled. The hdsl2ShdslEndpointCurrStatus is a bitmask representing all outstanding error conditions associated with a particular segment endpoint. Note that since the status of remote endpoints 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. Two alarm conditions, SNR Margin Alarm and Loop Attenuation Alarm, are organized in a manner slightly different from that implied in the EOC specifications. In the MIB module, these alarm conditions are Sikes, et al. Standards Track [Page 12]
RFC 4319 HDSL2-SHDSL-LINE-MIB December 2005 tied to the two thresholds, hdsl2ShdslEndpointThreshSNRMargin and hdsl2ShdslEndpointThreshLoopAttenuation, found in the hdsl2ShdslEndpointAlarmConfProfileTable. In the EOC, the alarm conditions associated with these thresholds are per unit. In the MIB module, these alarm conditions are per endpoint. For terminal units, this has no impact. For repeaters, this implies an implementation variance where the agent in the terminal unit is responsible for detecting a threshold crossing. As the reporting of a repeater detected alarm condition to the polling terminal unit occurs in the same EOC message as the reporting of the current SNR Margin and Loop Attenuation values, it is anticipated that this will have very little impact on agent implementation. 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. Notifications, other than the threshold notifications listed above, SHOULD be rate limited (throttled) such that there is at least a 1-minute gap between the generation of consecutive notifications of the same event. When notifications are rate limited, they are dropped and not queued for sending at a future time. This is intended to be a general rate-limiting statement for notifications that have no explicit rate-limiting assertions in this document otherwise. 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. An hdsl2ShdslSpanInvalidNumRepeaters notification may be generated following completion of the discovery phase if the number of repeaters discovered on the line differs from the number of repeaters specified in hdsl2ShdslSpanConfNumRepeaters. For those conditions where the number of provisioned repeaters is greater than those encountered during span discovery, all table entries associated with the nonexistent repeaters are to be discarded. For those conditions where the number of provisioned repeaters is less than those Sikes, et al. Standards Track [Page 13]
RFC 4319 HDSL2-SHDSL-LINE-MIB December 2005 encountered during span discovery, additional table entries are to be created using the default span configuration profile. 3.

RFC 4319 HDSL2-SHDSL-LINE-MIB December 2005 END 4. Implementation Analysis A management application that supports RFC 3276 could mistakenly flag a unit that responds with a rate or wire pair that exceeds the ranges and/or enumerations specified in RFC 3276. For example, a G.shdsl.bis line with four wire pairs would report statistics for wire pairs that do not exist in RFC 3276. That is, a GET-NEXT request issues with the object identifier: hdsl2ShdslEndpointCurrAtn.1.1.1.2 might return hdsl2ShdslEndpointCurrAtn.1.1.1.3 = 0 with a G.shdsl.bis unit and hdsl2ShdslEndpointCurrSnrMgn.1.1.1.1 = 0 with an HDSL2 unit as these objects are indexed by INDEX { ifIndex, hdsl2ShdslInvIndex, hdsl2ShdslendpointSide, hdsl2ShdslEndpointWirePair } A management application intended to manage G.shdsl.bis agents SHOULD be modified to accept this sequence. One should note that this same unmodified management application is still capable of managing G.shdsl.bis agents albeit to the degree of G.SHDSL (non-bis) limitations. That is, it can create and monitor configurations limited to two wire pairs with an upper-rate limit of 4112000 bits/second. 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. 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. These are the tables and objects and their sensitivity/vulnerability: Sikes, et al. Standards Track [Page 66]
RFC 4319 HDSL2-SHDSL-LINE-MIB December 2005 o hdsl2ShdslSpanConfTable The table consists of the following objects that support SET operations: * hdsl2ShdslSpanConfNumRepeaters * hdsl2ShdslSpanConfProfile * hdsl2ShdslSpanConfAlarmProfile Unauthorized changes to hdsl2ShdslSpanConfNumRepeaters could result in an hdsl2ShdslSpanInvalidNumRepeaters notification. Note the discussion on hdsl2ShdslSpanInvalidNumRepeaters in the Notifications section above. Unauthorized changes to hdsl2ShdslSpanConfProfile could have an adverse operational effect on a span. Reference the hdsl2ShdslSpanConfProfileTable discussion below. Unauthorized changes to hdsl2ShdslSpanConfAlarmProfile could have a contrary effect on notifications. Reference the hdsl2ShdslEndpointAlarmConfProfileTable discussion below. o hdsl2ShdslEndpointConfTable This table contains one object, hdsl2ShdslEndpointAlarmConfProfile, that supports SET operations. Unauthorized changes could have an undesirable notifications. Reference the hdsl2ShdslEndpointAlarmConfProfileTable discussion below. o hdsl2ShdslEndpointMaintTable The table consists of the following objects that support SET operations: * hdsl2ShdslMaintLoopbackConfig * hdsl2ShdslMaintPowerBackoff * hdsl2ShdslMaintSoftRestart Unauthorized changes to hdsl2ShdslMaintLoopbackConfig could prevent end-to-end data transfer due to an activation of a loopback. Unauthorized changes to hdsl2ShdslMaintPowerBackoff could result in an increased in bundle interference. Sikes, et al. Standards Track [Page 67]
RFC 4319 HDSL2-SHDSL-LINE-MIB December 2005 Unauthorized changes to hdsl2ShdslMaintSoftRestart could result in a temporary interruption of end-to-end data transfer as the result of the triggering of a soft restart. o hdsl2ShdslUnitMaintTable This table contains one object, hdsl2ShdslMaintLoopbackTimeout, that supports SET operations. An unauthorized change to this object could result in the timeout value for loopbacks being increased, decreased, or disabled. o hdsl2ShdslSpanConfProfileTable The table consists of the following objects that support SET operations: * hdsl2ShdslSpanConfWireInterface * hdsl2ShdslSpanConfMinLineRate * hdsl2ShdslSpanConfMaxLineRate * hdsl2ShdslSpanConfPSD * hdsl2ShdslSpanConfTransmissionMode * hdsl2ShdslSpanConfRemoteEnabled * hdsl2ShdslSpanConfPowerFeeding * hdsl2ShdslSpanConfCurrCondTargetMarginDown * hdsl2ShdslSpanConfWorstCaseTargetMarginDown * hdsl2ShdslSpanConfCurrCondTargetMarginUp * hdsl2ShdslSpanConfWorstCaseTargetMarginUp * hdsl2ShdslSpanConfUsedTargetMargins * hdsl2ShdslSpanConfReferenceClock * hdsl2ShdslSpanConfLineProbeEnable * hdsl2ShdslSpanConfProfileRowStatus Setting any of the objects to an incorrect value could have an adverse operational effect on a span. Unauthorized changes to the hdsl2ShdslSpanConfWireInterface could result in the failure of a span to achieve activation to a state that would permit data flow. For example, setting this object to six-wire or eight-wire operation when one of the units in the span only supports two-wire or four-wire operation would likely prevent an expected end-to-end data transfer capability. Unauthorized changes to hdsl2ShdslSpanConfMinLineRate or hdsl2ShdslSpanConfMaxLineRate could have an adverse effect on performance. The range of allowable line rates could be altered such that the span may not be able to train to a line rate that Sikes, et al. Standards Track [Page 68]
RFC 4319 HDSL2-SHDSL-LINE-MIB December 2005 would permit any end-user data to traverse the span or the span could train to a line rate that is either greater than or less than the line rate that the provider has pledged. Unauthorized changes to hdsl2ShdslSpanConfPSD or hdsl2ShdslSpanConfTransmissionMode could have a detrimental effect on loop reach, performance, or spectral compatibility. Unauthorized changes to hdsl2ShdslSpanConfRemoteEnable could alter the remote management ability of units. Unauthorized changes to hdsl2ShdslSpanConfPowerFeeding could shutdown units that are expected to be fed power remotely. Changing the configuration such that wetting current is not supplied may result in corrosion of electrical contacts. Unauthorized changes to hdsl2ShdslSpanConfCurrCondTargetMarginDown, hdsl2ShdslSpanConfWorstCaseTargetMarginDown, hdsl2ShdslSpanConfCurrCondTargetMarginUp, hdsl2ShdslSpanConfWorstCaseTargetMarginUp, or hdsl2ShdslSpanConfUsedTargetMargins could result in invalid parameters used to determine if a data rate can be supported under current and worst-case noise. Unauthorized changes to hdsl2ShdslSpanConfReferenceClock could result in the selection of a clock source that might either prevent any data from being transferred or impair data transfer. In addition, an increase in CRC anomalies may be experienced. Unauthorized changes to hdsl2ShdslSpanConfLineProbeEnable could have a negative effect on selecting the optimum rate or power level based on current line conditions. Unauthorized changes to row status could result in unwanted profiles being created or brought into service. Also, changes to the row status could result in profiles being inadvertently deleted or taken out of service. o hdsl2ShdslEndpointAlarmConfProfileTable The table consists of the following objects that support SET operations: * hdsl2ShdslEndpointThreshLoopAttenuation * hdsl2ShdslEndpointThreshSNRMargin * hdsl2ShdslEndpointThreshES * hdsl2ShdslEndpointThreshSES Sikes, et al. Standards Track [Page 69]
RFC 4319 HDSL2-SHDSL-LINE-MIB December 2005 * hdsl2ShdslEndpointThreshCRCanomalies * hdsl2ShdslEndpointThreshLOSWS * hdsl2ShdslEndpointThreshUAS * hdsl2ShdslEndpointAlarmConfProfileRowStatus Increasing any of the threshold values could result in a notification being suppressed or deferred. Setting a threshold to 0 could result in a notification being suppressed. Suppressing or deferring a notification could prevent the timely delivery of important diagnostic information. Decreasing any of the threshold values could result in a notification being sent from the network falsely reporting a threshold crossing. Changing a threshold value could also have an impact on the amount of notifications the agent sends. This document adds a paragraph, which was not in RFC 3276 [RFC3276], to the Notifications section that provides general guidance to the rate limiting of notifications. Agent implementations not adhering to the rate- limiting desires could result in notifications being generated at an uncontrolled rate. Unauthorized changes to a threshold value could result in an undesired notification rate. Unauthorized changes to row status could result in unwanted profiles being created or brought into service. Also, changes to the row status could result in profiles being inadvertently deleted or taken out of service. 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 hdsl2ShdslInventoryTable Access to these objects would allow an intruder to obtain information about which vendor's equipment is in use on the network. Further, such information is considered sensitive in many environments for competitive reasons. * hdsl2ShdslInvVendorID * hdsl2ShdslInvVendorModelNumber * hdsl2ShdslInvVendorSerialNumber * hdsl2ShdslInvVendorEOCSoftwareVersion * hdsl2ShdslInvStandardVersion * hdsl2ShdslInvVendorListNumber Sikes, et al. Standards Track [Page 70]
RFC 4319 HDSL2-SHDSL-LINE-MIB December 2005 * hdsl2ShdslInvVendorIssueNumber * hdsl2ShdslInvVendorSoftwareVersion * hdsl2ShdslInvEquipmentCode * hdsl2ShdslInvVendorOther * hdsl2ShdslInvTransmissionModeCapability SNMP versions prior to SNMPv3 did not include adequate security. Even if the network itself is secure (for example by using IPsec), even then, there is no control as to who on the secure network is allowed to access and GET/SET (read/change/create/delete) the objects in this MIB module. It is RECOMMENDED that implementers consider the security features as provided by the SNMPv3 framework (see [RFC3410], Section 8), including full support for the SNMPv3 cryptographic mechanisms (for authentication and privacy). Further, deployment of SNMP versions prior to SNMPv3 is NOT RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to enable cryptographic security. It is then a customer/operator responsibility to ensure that the SNMP entity giving access to an instance of this MIB module is properly configured to give access to the objects only to those principals (users) that have legitimate rights to indeed GET or SET (change/create/delete) them. 6.
