Definitions of Extension Managed Objects for Asymmetric Digital Subscriber Lines
RFC 3440: Definitions of Extension Managed Objects for Asymmetric Digital Subscriber Lines ๐ฆ
Okay bestie, this one is from the Network Working Group ๐ and it's written by F. Ly (Pedestal Networks) and G. Bathrick (Nokia). It's a Standards Track doc, dated December 2002. Its header doesn't list anything it obsoletes or updates, so it's standing on its own โจ
Status of this Memo ๐
This document specifies an Internet standards track protocol for the Internet community, and it's asking for discussion and suggestions for improvements ๐ซถ For the standardization state and status of this protocol, check the current edition of the "Internet Official Protocol Standards" (STD 1). Distribution of this memo is unlimited ๐

Abstract ๐ง
This memo defines a piece of the Management Information Base (MIB) for network management protocols in the Internet community ๐ธ Specifically, it describes extra managed objects for Asymmetric Digital Subscriber Line (ADSL) interfaces that the ADSL Line MIB (RFC 2662) doesn't cover. So it's the sequel nobody asked for but everybody needed ๐

1. The Internet-Standard Management Framework ๐
Okay so if you want the full tea on the current Internet-Standard Management Framework, go read section 7 of RFC 3410 [RFC3410] ๐ It's the main character of the framework docs โจ
Managed objects get accessed through a virtual information store called the Management Information Base, or MIB ๐ซง Most of the time you reach MIB objects through the Simple Network Management Protocol (SNMP). The objects inside the MIB are defined using the Structure of Management Information (SMI) mechanisms. This memo specifies a MIB module that is compliant with SMIv2, which is described in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580 [RFC2580] ๐
2. Introduction ๐
The whole point of this memo is to define a supplemental set of managed objects that the ADSL Line MIB doesn't cover (see [RFC2662]) โจ It's giving "the extra stuff you actually need." These additional objects come from ITU G.997.1 [ITU G.997.1] ๐
3. Relationship of ADSL Line Extension MIB with standard MIBs ๐ฆ
This section explains how the ADSL Line Extension MIB gets along with the other MIBs described in RFCs, which all have different levels of standardization ๐ The ADSL Line Extension MIB basically follows the same conventions as the ADSL Line MIB, with one exception ๐
That exception is about the RFC 2863 object ifOperstatus. It SHALL be down(2) when the ADSL line interface is in power state L3, which is defined in ITU G.992.1 [ITU G.992.1] and means no power at all ๐ฅถ When the interface is in power state L0 (power on) [ITU G.992.1] or L1 (reduced power), its value shall be up(1). Power Status L2 [ITU G.992.1] doesn't apply here, so it's a no-show ๐
4. Conventions used in the MIB ๐
4.1. Structure ๐งฉ
The MIB follows the same structure as the ADSL Line MIB [RFC2662]. Same vibes, same layout, zero surprises ๐
4.2. Additional Managed Objects โจ
Here are the objects for managing ADSL G.Lite, as defined in ITU G.992.2 [ITU G.992.2] ๐ธ
- 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
On top of managing G.Lite, another object got added so you can manage the ADSL line profile. That object is the line mode configuration ๐ซถ
4.2.1. ATU-C ADSL Transmission System Parameters and Line Mode ๐ฅ
The adslLineConfigTable needs an upgrade so it can control the ATU-C ADSL Transmission System ๐ Three objects get defined to monitor and configure the transmission mode, plus the actual line mode:
- Capability
- Configuration
- Actual Status
The transmission mode can also determine the line mode of the ADSL interface. For example, if g9921PotsNonOverlapped(2) is the actual value, the interface is running Full rate ADSL. If it's set to g9922PotsOverlapped(9), the interface is in G.Lite mode ๐ฆ
Here's how the transmission modes line up with the line modes:
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
If 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 dual mode ๐ Only one bit can be set in the Actual object, and it reflects the actual transmission mode as well as the line mode ๐ซง
4.2.2. Power Management ๐
Each managed ADSL interface running in G.Lite mode has three possible power states. L0 is power on, L1 is power on but reduced, and L3 is power off ๐ An operator can't configure the power state, but they can view it through the ifOperStatus object for the managed ADSL interface. ifOperStatus is set to down(2) if the interface is in power state L3, and to up(1) if the ADSL line interface is in power state L0 or L1 โจ
If the interface is running in G.Lite mode, the power state can also be monitored with the adslLineGlitePowerState object, which is defined in the ADSL Line Extension table. Its value enumerates the three power states the managed interface can reach ๐
4.2.3. Fast Retrain Parameters โก
Section 7.4.15 [ITU G.997.1] specifies the fast retrain parameters. They include two counters: the fast retrain count and the failed fast retrain count. Both counters have been added to all performance tables ๐
4.2.4. Counters for Severely Errored Second-line and Unavailable Seconds-line ๐
ITU G.997.1 sections 6.2.1.1.7 and 6.2.1.1.9 specify two counters that the ADSL Line MIB [RFC2662] doesn't cover ๐ซถ These two counters, severely errored seconds-line and unavailable seconds-line, get added to all the performance tables ๐
Unavailable seconds counts the cumulative seconds in which the interface was unavailable during the measured period. The count does not include seconds where the unavailability was caused solely by fast retrains and failed fast retrains. Fast retrains and failed fast retrains are considered part of normal network operation, so they don't count as unavailable errors ๐ธ
4.2.5. Counters, Interval Buckets and Thresholds ๐ชฃ
For physical-level events, there are counters: a current 15-minute bucket, one (up to 96) 15-minute history bucket(s) of "interval-counters", and current and previous 1-day interval-counters ๐งฎ Threshold notification can be configured for each physical-layer current 15-minute bucket โฐ
There is no requirement for an agent to keep a fixed relationship between the start of a fifteen-minute interval and any wall clock ๐ฐ๏ธ Some implementations may still align the fifteen-minute intervals with quarter hours, and an implementation may also choose to align one-day intervals with the start of a day ๐
The 96 interval-counters get their own separate tables, indexed by {ifIndex, AdslAtu*IntervalNumber} ๐
Counters are not reset when an ATU-C or ATU-R is reinitialized. They only reset when the agent is reset or reinitialized, or under a specific request that falls outside the scope of this MIB ๐
The 15-minute event counters are of the types PerfCurrentCount and PerfIntervalCount. The 1-day event counters are of the types AdslPerfCurrDayCount and AdslPerfPrevDayCount. Both the 15-minute and 1-day time elapsed counters are of the type AdslPerfTimeElapsed โณ
4.2.6. Alternative profile configuration for the dual line mode interface ๐ง
The object adslLineConfProfileDualLite is only used when the interface (the ADSL line and, if applicable, the channel) is configured as dual mode. In other words, adslLineTransAtucConfig is configured with one or more full-rate modes and one or more G.Lite modes ๐ฆ
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 ๐
If only full-rate modes are configured, or only G.Lite modes are configured, you only need the original full-rate profile. The dual-mode profile object is only needed when both full-rate and G.Lite profiles are needed. In that case, it gets set to the value of adslLineConfProfile when 'dynamic' profiles are implemented ๐
When 'static' profiles are implemented, though, the object works like adslLineConfProfileName [RFC2662] and has to algorithmically represent the line ๐ง Its value is the line's ifIndex plus a value that indicates the line mode type (for example, G.Lite or Full-rate). So the profile's name is a string made by concatenating the ifIndex with either Full or Lite. This string is fixed-length (that means 14 characters) with leading zero(s). For example, the profile name for an ifIndex equal to '15' on a full rate line is '0000000015Full' ๐ซถ
5. Conformance and Compliance ๐

okay the power state one is giving main character energy ๐ adslLineGlitePowerState has four values: none, L0, L1 and L3, and it's tied to ifOperStatus, so it's the link's mood ring ๐ง the mode-to-value mapping is spelled out right there in the DESCRIPTION, so read it closely, it's lowkey important ๐

::= { adslLineExtEntry 4 }
and then there's adslLineConfProfileDualLite ๐ฆ this one is for dual mode, which just means you've got full-rate and G.Lite modes enabled at the same time, and it's basically the profile name tea โ the value depends on whether profiles are dynamic or static, and for static ones the name gets built from the ifIndex plus Full or Lite, always 14 characters, zero-padded ๐ธ
adslLineConfProfileDualLite OBJECT-TYPE
SYNTAX SnmpAdminString
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"This object extends the definition an ADSL line and
associated channels (when applicable) for cases
when it is configured in dual mode, and operating
in a G.Lite-type mode as denoted by
adslLineTransAtucActual. Dual mode exists when the
object, adslLineTransAtucConfig, is configured with
one or more full-rate modes and one or more G.Lite
modes simultaneously.
When 'dynamic' profiles are implemented, the value
of object is equal to the index of the applicable
row in the ADSL Line Configuration Profile Table,
AdslLineConfProfileTable defined in ADSL-MIB
[RFC2662].
In the case when dual-mode has not been enabled,
the value of the object will be equal to the value
of the object adslLineConfProfile [RFC2662].
When `static' profiles are implemented, in much
like the case of the object,
adslLineConfProfileName [RFC2662], this object's
value will need to algorithmically represent the
characteristics of 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
concatenating the 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'."

9. Security Considerations ๐จ
Okay bestie, this part is SERIOUS. Like, read it carefully before you touch this MIB ๐ญ๐ฅ
The following security matters should be considered when implementing this MIB.
- 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 (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 modifying notification thresholds such as Signal-to-Noise Ratio (SNR) margins.
- SNMPv1 by itself is such an insecure environment. Even if the network itself is secure (for example by using IPSec), there is no control over 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 STD 62, RFC 3414 [RFC3414] and the View-based Access Control Model STD 62, RFC 3415 [RFC3415] 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 only those objects, and to those principals (users) that have legitimate rights to access them.
- 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 needs to stay consistent with the implementation of RFC 2662.
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, andadslAturThreshold15MinUasL.
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 it is 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 a view of the profile on a customer-by-customer standpoint, but should be cautious of the dynamic nature of these objects.
- 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.
