In particular, it describes additional managed objects used for managing Asymmetric Digital Subscriber Line (ADSL) interfaces not covered by the ADSL Line MIB [RFC2662]. 3. The SNMP Network Management Framework Expires August 2002 [Page 1] INTERNET-DRAFT ADSL Line Extension MIB April 23, 2002 The SNMP Management Framework presently consists of five major components: o An overall architecture, described in RFC 2571 [RFC2571]. o Mechanisms for describing and naming objects and events for the purpose of management. The first version of this Structure of Management Information (SMI) is called SMIv1 and described in STD 16, RFC 1155 [RFC1155], STD 16, RFC 1212 [RFC1212] and RFC 1215 [RFC1215]. The second version, called SMIv2, is described in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580 [RFC2580]. o Message protocols for transferring management information. The first version of the SNMP message protocol is called SNMPv1 and described in STD 15, RFC 1157[RFC1157]. A second version of the SNMP message protocol, which is not an Internet standards track protocol, is called SNMPv2c and described in RFC 1901 [RFC1901] and RFC 1906 [RFC1906]. The third version of the message protocol is called SNMPv3 and described in RFC 1906 [RFC1906], RFC2572 [RFC2572] and RFC 2574 [RFC2574]. o Protocol operations for accessing management information. The first set of protocol operations and associated PDU formats is described in STD 15, RFC 1157 [RFC1157]. A second set of protocol operations and associated PDU formats is described in RFC 1905 [RFC1905]. o A set of fundamental applications described in RFC 2573 [RFC2573] and the view-based access control mechanism described in RFC 2575 [RFC2575]. A more detailed introduction to the current SNMP Management Framework can be found in RFC 2570 [RFC2570]. Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. Objects in the MIB are defined using the mechanisms defined in the SMI. This memo specifies a MIB module that is compliant to the SMIv2. A MIB conforming to the SMIv1 can be produced through the appropriate translations. The resulting translated MIB must be semantically equivalent, except where objects or events are omitted because no translation is possible (use of Counter64). Some machine-readable information in SMIv2 will be converted into textual descriptions in SMIv1 during the translation process. However, this loss of machine readable information is not considered to change the semantics of the MIB. Expires August 2002 [Page 2] INTERNET-DRAFT ADSL Line Extension MIB April 23, 2002 4. Introduction The purpose of this memo is to define a supplemental set of managed objects that is not covered by ADSL Line MIB as defined in [RFC2662]. This memo addresses the additional objects defined in ITU G.997.1 [ITU G.997.1]. 5. Relationship of ADSL Line Extension MIB with standard MIBs This section outlines the relationship of ADSL Line Extension MIB with other MIBs described in RFCs and in their various degrees of standardization. In regards to these relationship, the ADSL Line Extension MIB follows conventions as used by the ADSL Line MIB with one exception. The value of the RFC2863 object, ifOperstatus, SHALL be down(2) when the ADSL line interface is in power state L3 as defined in ITU G.992.1 [ITU G.992.1], which means no power. Its value shall be up(1) if the ADSL line interface is in power state L0 (power on) [ITU G.992.1] or L1 (reduced power). Power Status L2 [ITU G.992.1] is not applicable. 6. Conventions used in the MIB 6.1 Structure The MIB is organized to follow the same structure of the ADSL Line MIB [RFC2662]. 6.2 Additional Managed Objects Objects specific to the management of ADSL G.Lite as defined in ITU G.992.2 [ITU G.992.2] are: - ADSL Transceiver Unit - Central Office End (ATU-C) Transmission System and Line Mode - Power Management - Counters for Fast Retrains and Failed Fast Retrains - Counters for Severe Error Second-line and Unavailable Second - Alternative profile configuration for the Dual line mode interface Besides the management of G.Lite, another object has been added in order to manage the ADSL line profile. The object is the line mode configuration. 6.2.1 ATU-C ADSL Transmission System Parameters and Line Mode The adslLineConfigTable needs to be extended to cover control of the ATU-C ADSL Transmission system. Three objects are defined to monitor Expires August 2002 [Page 3] INTERNET-DRAFT ADSL Line Extension MIB April 23, 2002 and configure the transmission mode as well as the actual line mode: - Capability - Configuration - Actual Status Transmission modes can further determine the line mode of the ADSL interface. For example, if g9921PotsNonOverlapped(2) is the actual value of the ADSL interface, the interface is operating in Full rate ADSL. If the interface is set to g9922PotsOverlapped(9), the interface is operating in G.Lite mode. The transmission mode and the corresponding line mode are defined as: Transmission mode Line Mode ---------------------------------------------------------- Regional Std. (ANSI T1.413) Full [ANSI T1.413] Regional Std. (ETSI DTS/TM06006) Full [ETSI DTS/TM06006] G.992.1 [ITU G992.1] POTS non-overlapped Full G.992.1 POTS overlapped Full G.992.1 Integrated Services Digital Network (ISDN) non-overlapped Full G.992.1 ISDN overlapped Full G.992.1 TCM-ISDN non-overlapped Full G.992.1 TCM-ISDN overlapped Full G.992.2 POTS non-overlapped G.Lite G.992.2 POTS overlapped G.Lite G.992.2 with TCM-ISDN G.Lite non-overlapped G.992.2 with TCM-ISDN overlapped G.Lite G.992.1 TCM-ISDN symmetric Full Table 1: Transmission Mode and Line Mode In case more than one bit is configured for an ADSL interface and both Full and G.Lite modes are selected, the interface is said to be configured in the dual mode. Only one bit can be set in the Actual object that reflects the actual mode of transmission as well as the line mode. 6.2.2 Power Management There are three possible power states for each managed ADSL interface operating in the G.Lite mode. L0 is power on, L1 is power on but reduced and L3 is power off. Power state cannot be configured by an operator but it can be viewed via the ifOperStatus object for the Expires August 2002 [Page 4] INTERNET-DRAFT ADSL Line Extension MIB April 23, 2002 managed ADSL interface. The value of the object ifOperStatus is set to down(2) if the ADSL interface is in power state L3 and is set to up(1) if the ADSL line interface is in power state L0 or L1. An ADSL line power state, if the interface is operating in the G.Lite mode, can also be monitored by the adslLineGlitePowerState object defined in the ADSL Line Extension table. The value of the object enumerates the three power states attainable by the managed interface. 6.2.3 Fast Retrain Parameters Section 7.4.15 [ITU G.997.1] specifies fast retrain parameters. Fast retrain parameters include two counters: fast retrain count and failed fast retrain count. These two counters have been added to all performance tables. 6.2.4 Counters for Severely Errored Second-line and Unavailable Seconds-line ITU G.997.1 sections 6.2.1.1.7 and 6.2.1.1.9 specify two counters that are not covered by the ADSL Line MIB [RFC2662]. These two counters (severely errored seconds-line and unavailable seconds-line) are added to all the performance tables. Unavailable seconds counts cumulative number of seconds in which the interface was unavailable during the measured period. This counter does not include the seconds in which unavailability was caused solely by fast retrains and failed fast retrains. Fast retrains and failed fast retrains are considered to be part of the normal network operation and thus are not counted as unavailable errors. 6.2.5 Counters, Interval Buckets and Thresholds For physical-level events, there are 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. Threshold notification can be configured for each physical-layer current 15-minute bucket. 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}. Expires August 2002 [Page 5] INTERNET-DRAFT ADSL Line Extension MIB April 23, 2002 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. 6.2.6 Alternative profile configuration for the dual line mode interface The object, adslLineConfProfileDualLite, is used only when the interface (the ADSL line and, if applicable, channel) is configured as dual mode, that is, the object adslLineTransAtucConfig is configured with one or more full-rate modes and one or more G.Lite modes. The object adslLineConfProfile defined in ADSL-MIB [RFC2662] is used as the primary full-rate profile. The newly added object in this MIB module, adslLineConfProfileDualLite, is used to describe and configure the G.Lite profile. Note that if one or more full-rate modes are configured, or only G.Lite modes are configured, only the original full-rate profile is needed. The dual-mode profile object is only needed when both full-rate and G.Lite profiles are needed. In this case, it will be set to the value of adslLineConfProfile when 'dynamic' profiles are implemented. When 'static' profiles are implemented, however, similar to the case of the object, adslLineConfProfileName [RFC2662], this object's value will need to algorithmically represent the line. In this case, the value of the line's ifIndex plus a value indicating the line mode type (e.g., G.Lite, Full-rate) will be used. Therefore, the profile's name is a string of the concatenation of ifIndex and one of the follow values: Full or Lite. This string will be fixed-length (i.e., 14) with leading zero(s). For example, the profile name for ifIndex that equals '15' and is a full rate line, it will be '0000000015Full'. 7.

Security Considerations The following security matters should be considered when implementing this MIB. 1) Blocking unauthorized access to the ADSL MIB via the element management system is outside the scope of this document. It should be Expires August 2002 [Page 32] INTERNET-DRAFT ADSL Line Extension MIB April 23, 2002 noted that access to the MIB permits the unauthorized entity to modify the profiles (section 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 notification thresholds such as Signal-to-Noise Ratio (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 Model RFC 2574 [21] and the View-based Access Control Model RFC 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) The profile mechanism presented in this document requires specific attention. The implementor of this MIB has a choice of implementing either 'static' or 'dynamic' profiles. This decision must be consistent with the implementation of RFC2662. In the case of 'static' profiles, the elements of the profile are read-write as opposed to read-create when 'dynamic' profiles are implemented: - adslConfProfileLineType, - adslAtucThreshold15MinFailedFastR, - adslAtucThreshold15MinSesL, - adslAtucThreshold15MinUasL, - adslAturThreshold15MinSesL, and - adslAturThreshold15MinUasL. Expires August 2002 [Page 33] INTERNET-DRAFT ADSL Line Extension MIB April 23, 2002 This decision also impacts the mechanics of the index, adslLineConfProfileDualLite. When 'static' profiles are implemented, its value is algorithmically set by the system and its value is based on the ifIndex, hence not guaranteed across system reboots. Similar to the handling of adslLineConfProfile [RFC2662], the implementor of this MIB must ensure that the profile object values associated with these indices are maintained across system reboots. In the case of dynamic profiles, this object is set by the SNMP manager. The implementor of this MIB may want to provide view of the profile on a customer-by-customer standpoint, but should be cautious of the dynamic nature of these objects. 4) ADSL layer connectivity from the ATU-R will permit the subscriber to manipulate both the ADSL link directly and the ADSL overhead control channel(AOC)/embedded operations channel (EOC) for their own loop. For example, unchecked or unfiltered fluctuations initiated by the subscriber could generate sufficient notifications to potentially overwhelm either the management interface to the network or the element manager. Other attacks affecting the ATU-R portions of the MIB may also be possible. 12.
