2. Abstract
This document defines a standard SNMP MIB for additional functions
not covered by the ADSL Line MIB [1].
3. The SNMP Network Management Framework
Expires August 2000 [Page 1]
INTERNET-DRAFT ADSL Line Extension MIB January 14, 2001
The SNMP Management Framework presently consists of five major
components:
o An overall architecture, described in RFC 2571 [11].
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 [14], STD 16, RFC 1212 [15] and RFC 1215 [16]. The
second version, called SMIv2, is described in STD 58, RFC 2578
[1], STD 58, RFC 2579 [2] and STD 58, RFC 2580 [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
descriptions in SMIv1 during the translation process. However, this
loss of machine readable information is not considered to change the
semantics of the MIB.

5. 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
[10]. This memo addresses the additional objects defined in ITU
G.997.1 [8]. These additional objects specifically address the
management capabilities of ADSL "Lite" as defined by ITU-T G.992.2
[9].
6. Relationship of the 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". ADSL Line Extension MIB obeys the same
relationship between ADSL Line MIB to other standard MIBs with one
exception for the ifOperStatus as defined in RFC 1213 [3].
6.1 ifOperStatus
Expires August 2000 [Page 3]
INTERNET-DRAFT ADSL Line Extension MIB January 14, 2001
ifOperStatus is set to down(2) when the ADSL line interface is in
power state L2, which means no power. ifOperStatus is set to up(1)
if the ADSL line interface is in power state L0 (power on) or L1
(reduced power).
7. Conventions used in the MIB
7.1 Structure
The MIB is organized to follow the same structure of the ADSL Line
MIB [1].
7.2 Additional Managed Objects
A few objects are added to cover the ADSL "Lite" management and they
are:
- 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 ADSL "Lite", another object has been
added to the ADSL Line MIB [10] in order to manage the ADSL line
profile. The object is the line mode configuration.
The MIB definitions are attached. The MIB will be branched from
the ADSL Line MIB [10].
7.2.1 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.
Expires August 2000 [Page 4]
INTERNET-DRAFT ADSL Line Extension MIB January 14, 2001
The transmssion mode and the corresponding line mode are defined
as:
Transmission mode Line Mode
----------------------------------------------------------
Regional Std. (ANSI T1.413) Full
Regional Std. (ETSI DTS/TM06006) Full
G.992.1 POTS non-overlapped Full
G.992.1 POTS overlapped Full
G.992.1 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 Lite
G.992.2 POTS overlapped Lite
G.992.2 with TCM-ISDN non-overlapped Lite
G.992.2 with TCM-ISDN overlapped 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 Lite modes are selected, the interface is said to
configure 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.
7.2.2 Power Management
There are three power states for each managed ADSL interface
operating in the G.lite mode. L0 is power on, L1 is power on but
reduced and L2 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 L2 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.
7.2.3 Fast Retrain Parameters
Section 7.4.15 of 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
Expires August 2000 [Page 5]
INTERNET-DRAFT ADSL Line Extension MIB January 14, 2001
performance tables.
7.2.4 Counters for Severe Error Second-line and Unavailable Second
Section 7.2.1.1.7 and section 7.2.1.1.9 specify two counters
that are not covered by the ADSL Line MIB [10]. These two counters
(severe error seconds-line and unavailable seconds) 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 retrins. Fast
retrains and failed fast retrains are considered to be part of the
normal network operation and thus are not counted as unavailable
errors.
7.2.5 Alternative profile configuration for the Dual line mode
interface
This object is used only when the interface (for the ADSL line
or channel) is configured as dual mode, that is, the object
adslLineTransAtucConfig is configued with one or more full-rate modes
and one or more Lite modes.
The object adslLineConfProfile defined in ADSL-MIB [10] is used
as the primary full-rate profile. The newly added object in this MIB
module, adslLineConfProfileDualLite is used to describe or configure
the Lite profile. Note that if one or more full-rate modes are
configured, or only 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 lite profiles are needed.
If the static profile is used, the profile name is the ifIndex
ASCII string plus the differentiator string appended to the end of
the static profile name. For example, for interface 100, the object
adslLineConfProfile is set by the agent to be "100Full" and the
object adslLineConfProfileDualLite is set to be "100Lite".

10. 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 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 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
Expires August 2000 [Page 29]
INTERNET-DRAFT ADSL Line Extension MIB January 14, 2001
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) 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.
