4. Implementation Analysis
A management application intended to manage ADSL links (e.g.,
G.992.1) with this MIB module MUST be modified to adapt itself to
certain differences between RFC 2662 [RFC2662] and this MIB module, including the following aspects: o Though the configuration templates/profiles allow referring to 1-4 bearer channels, ADSL links are limited to two channels at most. o Though the channel configuration profile allows higher data rates, ADSL links are limited to downstream/upstream data rate as assumed in RFC 2662 [RFC2662]. o The Impulse Noise Protection (INP) configuration parameters are given by minimum protection and maximum delay parameters. o The line configuration profile includes a sub-table that addresses mode-specific parameters. For ADSL links, the management application SHOULD create a row in that table for the ADSL modes only. o The line configuration profile includes parameters that are irrelevant for ADSL links. Similarly, many status parameters in the MIB are irrelevant for certain ADSL modes. Therefore, it is advised to consult with ITU G.997.1 standard [G.997.1] regarding the scope and relevance of each parameter in this MIB.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:
o xdsl2LineTable
The table consists of the following objects that support SET
operations:
* xdsl2LineConfTemplate
* xdsl2LineConfFallbackTemplate
* xdsl2LineAlarmConfTemplate
* xdsl2LineCmndConfPmsf
* xdsl2LineCmndConfLdsf
* xdsl2LineCmndConfBpsc
* xdsl2LineCmndAutomodeColdStart
* xdsl2LineCmndConfReset
Unauthorized changes to xdsl2LineConfTemplate could have a major
adverse operational effect on many lines simultaneously.
Unauthorized changes to xdsl2LineConfFallbackTemplate could have a
major adverse operational effect on many lines simultaneously.
Unauthorized changes to xdsl2LineAlarmConfTemplate could have a
contrary effect on notifications.
Unauthorized changes to xdsl2LineCmndConfPmsf could have an
adverse affect on the power consumption of a line and may disrupt
an operational service.
Unauthorized changes to xdsl2LineCmndConfLdsf could cause an
unscheduled line test to be carried out on the line.
Unauthorized changes to xdsl2LineCmndConfBpsc could cause an
unscheduled bits-per-subcarrier measurement to be carried out on
the line.
Unauthorized changes to xdsl2LineCmndAutomodeColdStart could cause
an unscheduled cold reset to the line.
Unauthorized changes to xdsl2LineCmndConfReset could cause a
unscheduled retrain of a line.
o xdsl2LineSegmentTable
This table contains one object, xdsl2LineSegmentRowStatus, that
supports SET operations. Unauthorized changes could result in
measurement results being deleted prematurely.
o xdsl2SCStatusTable
This table contains one object, xdsl2SCStatusRowStatus, that
supports SET operations. Unauthorized changes could result in
line test results being deleted prematurely.
o xdsl2LineConfTemplateTable
The table consists of the following objects that support SET
operations:
* xdsl2LConfTempLineProfile
* xdsl2LConfTempChan1ConfProfile
* xdsl2LConfTempChan1RaRatioDs
* xdsl2LConfTempChan1RaRatioUs
* xdsl2LConfTempChan2ConfProfile
* xdsl2LConfTempChan2RaRatioDs
* xdsl2LConfTempChan2RaRatioUs
* xdsl2LConfTempChan3ConfProfile
* xdsl2LConfTempChan3RaRatioDs
* xdsl2LConfTempChan3RaRatioUs
* xdsl2LConfTempChan4ConfProfile
* xdsl2LConfTempChan4RaRatioDs
* xdsl2LConfTempChan4RaRatioUs
* xdsl2LConfTempRowStatus
Unauthorized changes to xdsl2LConfTempLineProfile,
xdsl2LConfTempChan1ConfProfile, xdsl2LConfTempChan2ConfProfile,
xdsl2LConfTempChan3ConfProfile, or xdsl2LConfTempChan4ConfProfile
could have an adverse operational effect on several lines; could
change several lines over to running in unwanted levels of
operation; or could result in several services undergoing changes
in the number of channels that carry the service.
Unauthorized changes to xdsl2LConfTempChan1RaRatioDs,
xdsl2LConfTempChan2RaRatioDs, xdsl2LConfTempChan3RaRatioDs, or
xdsl2LConfTempChan4RaRatioDs would alter the relative rate
allocations among all channels belonging to a line. This could
have an adverse operational effect on several lines.
Unauthorized changes to xdsl2LConfTempRowStatus could result in
templates being created or brought into service prematurely, or
they could result in templates being inadvertently deleted or
taken out of service.
o xdsl2LineConfProfTable
The table consists of the following objects that support SET
operations:
* xdsl2LConfProfScMaskDs
* xdsl2LConfProfScMaskUs

* xdsl2LConfProfRaUsTimeUs
* xdsl2LConfProfRaDsNrmDs
* xdsl2LConfProfRaDsNrmUs
* xdsl2LConfProfRaDsTimeDs
* xdsl2LConfProfRaDsTimeUs

* xdsl2LConfProfMaxSnrmUs
* xdsl2LConfProfMinSnrmDs
* xdsl2LConfProfMinSnrmUs
* xdsl2LConfProfMsgMinUs
* xdsl2LConfProfMsgMinDs
* xdsl2LConfProfCeFlag

* xdsl2LConfProfUs0Mask
* xdsl2LConfProfForceInp
* xdsl2LConfProfRowStatus
Unauthorized changes resulting in the setting of any of the above
objects to an incorrect value could have an adverse operational
effect on several lines.
Also, unauthorized changes to xdsl2LConfProfRowStatus could result
in unwanted line profiles being created or brought into service
prematurely, or they could result in line profiles being
inadvertently deleted or taken out of service.
o xdsl2LineConfProfModeSpecTable
The table consists of the following objects that support SET
operations:
* xdsl2LConfProfMaxNomPsdDs
* xdsl2LConfProfMaxNomPsdUs
* xdsl2LConfProfMaxNomAtpDs
* xdsl2LConfProfMaxNomAtpUs
* xdsl2LConfProfMaxAggRxPwrUs
* xdsl2LConfProfPsdMaskDs

* xdsl2LConfProfLimitMask
* xdsl2LConfProfUs0Disable
* xdsl2LConfProfModeSpecRowStatus
Unauthorized changes resulting in the setting of any of the above
objects to an incorrect value could have an adverse operational
effect on several lines.
Also, unauthorized changes to xdsl2LConfProfModeSpecRowStatus
could result in unwanted PSD configurations being created or
brought into service prematurely, or they could result in PSD
configurations being inadvertently deleted or taken out of
service.
o xdsl2LineConfProfModeSpecBandUsTable
The table consists of the following objects that support SET
operations:
* xdsl2LConfProfUpboPsdA
* xdsl2LConfProfUpboPsdB
* xdsl2LConfProfModeSpecRowStatus
Unauthorized changes resulting in the setting of any of the above
objects to an incorrect value could have an adverse operational
effect on several lines.
Also, unauthorized changes to
xdsl2LConfProfModeSpecBandUsRowStatus could result in unwanted PSD
configurations being created or brought into service prematurely,
or they could result in PSD configurations being inadvertently
deleted or taken out of service.
o xdsl2ChConfProfileTable
The table consists of the following objects that support SET
operations:
* xdsl2ChConfProfMinDataRateDs
* xdsl2ChConfProfMinDataRateUs
* xdsl2ChConfProfMinResDataRateDs

* xdsl2ChConfProfInitPolicy
* xdsl2ChConfProfRowStatus
Unauthorized changes resulting in the setting of any of the above
objects to an incorrect value could have an adverse operational
effect on several lines.
Also, unauthorized changes to xdsl2ChConfProfRowStatus could
result in unwanted channel profiles being created or brought into
service prematurely, or they could result in channel profiles
being inadvertently deleted or taken out of service.
o xdsl2LineAlarmConfTemplateTable
The table consists of the following objects that support SET
operations:
* xdsl2LAlarmConfTempLineProfile

* xdsl2LalarmConfTempChan4ConfProfile
* xdsl2LAlarmConfTempRowStatus
Unauthorized changes to xdsl2LAlarmConfTempLineProfile,
xdsl2LAlarmConfTempChan1ConfProfile,
xdsl2LAlarmConfTempChan2ConfProfile,
xdsl2LAlarmConfTempChan3ConfProfile, or
xdsl2LAlarmConfTempChan4ConfProfile could have an adverse effect
on the management of notifications generated at the scope of
several to many lines, or they could change several to many lines
over to running with unwanted management rates for generated
notifications.
Unauthorized changes to xdsl2LAlarmConfTempRowStatus could result
in alarm templates being created or brought into service
prematurely, or they could result in alarm templates being
inadvertently deleted or taken out of service.
o xdsl2LineAlarmConfProfileTable
The table consists of the following objects that support SET
operations:
* xdsl2LineAlarmConfProfileXtucThresh15MinFecs
* xdsl2LineAlarmConfProfileXtucThresh15MinEs
* xdsl2LineAlarmConfProfileXtucThresh15MinSes
* xdsl2LineAlarmConfProfileXtucThresh15MinLoss

* xdsl2LineAlarmConfProfileThresh15MinFailedFullInt
* xdsl2LineAlarmConfProfileThresh15MinFailedShrtInt
* xdsl2LineAlarmConfProfileRowStatus
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.
Unauthorized changes to row status could result in unwanted line
alarm profiles being created or brought into service. Also,
changes to the row status could result in line alarm profiles
being inadvertently deleted or taken out of service.

* xdsl2LineAlarmConfProfileXturThresh15MinUas
* xdsl2LineAlarmConfProfileThresh15MinFailedFullInt
* xdsl2LineAlarmConfProfileThresh15MinFailedShrtInt
* xdsl2LineAlarmConfProfileRowStatus
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.
Unauthorized changes to row status could result in unwanted
channel alarm profiles being created or brought into service.
Also, changes to the row status could result in channel alarm
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 xdsl2LineInventoryTable
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.
* xdsl2LInvG994VendorId
* xdsl2LInvSystemVendorId
* xdsl2LInvVersionNumber
* xdsl2LInvSerialNumber
* xdsl2LInvSelfTestResult
* xdsl2LInvTransmissionCapabilities
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).
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 only to those objects whose
principals (users) have legitimate rights to indeed GET or SET
(change/create/delete) them.
