This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
In particular, it describes additional managed objects used for
managing Asymmetric Digital Subscriber Line (ADSL) interfaces not
covered by the ADSL Line MIB [RFC2662].
1. The SNMP Network Management Framework
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. (RFC 2662).
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.
2. 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].
3. 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.
4. Conventions used in the MIB
4.1 Structure
The MIB is organized to follow the same structure of the ADSL Line
MIB [RFC2662].
4.2 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.
4.2.1 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
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.
4.2.2 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
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.
4.2.3 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.
4.2.4 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.
4.2.5 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}.
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.
4.2.6 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 document is a string of the concatenation of ifIndex and one product 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'.

DESCRIPTION
"This object extends the definition an ADSL line and
associated channels (when applicable) Internet standards track protocol 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' Internet community, and is a full rate line, it
will be '0000000015Full'."

The following security matters should RFC-DIST list.
Requests to be considered when implementing
this MIB.
1) Blocking unauthorized access added to or deleted from the ADSL MIB via the element
management system is outside the scope of this document. It IETF distribution list
should be
noted that access sent to the MIB permits the unauthorized entity IETF-REQUEST@IETF.ORG. Requests 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
added to contain sensitive information. In particular, or deleted from the
certain objects may RFC-DIST distribution list should
be considered sensitive in many environments,
since it would allow an intruder sent to obtain information about which
vendor's equipment is in use RFC-DIST-REQUEST@RFC-EDITOR.ORG.
Details 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 obtaining RFCs 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' FTP or 'dynamic' profiles. This decision must EMAIL may 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.
This decision also impacts the mechanics of the index,
adslLineConfProfileDualLite. When 'static' profiles are implemented,
its value is algorithmically set obtained by the system and its value is
based on the ifIndex, hence not guaranteed across system reboots.
Similar sending
an EMAIL message to the handling of adslLineConfProfile [RFC2662], the
implementor of this MIB must ensure that the profile object values
associated rfc-info@RFC-EDITOR.ORG 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 message body
help: ways_to_get_rfcs. For example:
To: rfc-info@RFC-EDITOR.ORG
Subject: getting rfcs
help: ways_to_get_rfcs
Requests for special distribution 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 addressed 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.
