1. The Internet-Standard Management Framework 1. Introduction
For a detailed overview of the documents that describe the current This document defines a portion of the Management Information Base
Internet-Standard Management Framework, please refer to section 7 of (MIB) module for use with network management protocols in the
RFC 3410 [RFC3410]. Internet community. The MIB described in RFC 3276 [RFC3276]
describes objects used for managing High Bit-Rate DSL - 2nd
generation (HDSL2) [T1E1.4] and Single-Pair High-Speed Digital
Subscriber Line (SHDSL) interfaces [G.991.2]. This document
obsoletes RFC 3276 [RFC3276] which supports G.SHDSL in that the MIB
described herein supports G.SDHSL.bis as described in the G.991.2
[G.991.2]. In addition, objects have been added to improve the
management of SHDSL lines.
Managed objects are accessed via a virtual information store, termed 2. The SNMP Management Framework
the Management Information Base or MIB. MIB objects are generally
accessed through the Simple Network Management Protocol (SNMP). The SNMP Management Framework presently consists of five major
Objects in the MIB are defined using the mechanisms defined in the components:
Structure of Management Information (SMI). This memo specifies a MIB
module that is compliant to the SMIv2, which is described in STD 58, o An overall architecture, described in RFC 3411 [RFC3411].
RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
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 is 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], RFC 2579 [RFC2579], and RFC 2580
[RFC2580]. [RFC2580].
o Message protocols for transferring management information. The
first version of the SNMP message protocol is called SNMPv1 and is
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 is in RFC 1901 [RFC1901]
and RFC 3417 [RFC3417]. The third version of the message protocol
is called SNMPv3 and is described in RFC 3417 [RFC3417], RFC 3412
[RFC3412], and RFC 3414 [RFC3414].
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 3416
[RFC3416].
o A set of fundamental applications described in RFC 3413 [RFC3413]
and the view-based access control mechanism described in RFC 3415
[RFC3415].
A more detailed introduction to the current SNMP Management Framework
can be found in RFC 3410 [RFC3410].
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.

conventions defined in the HDSL2-SHDSL Line MIB (RFC 3276) [RFC3276] These definitions are based upon the specifications for the HDSL2 and
to support equivalent management of a G.SHDSL.bis interface. These SHDSL Embedded Operations Channel (EOC) as defined in ANSI T1E1.4/
extensions are based upon the specifications for G.SHDSL.bis 2000-006 [T1E1.4] and ITU G.991.2 [G.991.2].
as defined in the ITU documentation [ITUXXXX].
2.1. Relationship of G.SHDSL.bis to G.SHDSL The MIB is located in the MIB tree under MIB 2 transmission, as
discussed in the MIB-2 Integration (RFC 3418 [RFC3418] and RFC 2863
[RFC2863]) section of this document.
As discussed in RFC3276, G.SHDSL supports up to two wire pairs in 3.1 Relationship of the HDSL2/SHDSL Line MIB to other MIBs
a G.SHDSL line. With G.SHDSL.bis, the ITU has extended the
specification of G.SHDSL to support an additional two pairs of wires.
Thus, to support G.SHDSL.bis, several textual conventions and objects This section outlines the relationship of this MIB with other MIBs
must have their ranges and enumerations changed. described in RFCs. Specifically, IF-MIB as presented in RFC 2863
[RFC2863] is discussed.
A modified version of Figure 2 from RFC3276, section 4.3.1, is below: 3.1.1 General IF-MIB Integration (RFC 2863)
The HDSL2/SHDSL Line MIB specifies the detailed attributes of a data
interface. As such, it needs to integrate with RFC 2863 [RFC2863].
The IANA has assigned the following ifTypes to HDSL2 and SHDSL:
IANAifType ::= TEXTUAL-CONVENTION
...
SYNTAX INTEGER {
...
hdsl2 (168), -- High Bit-Rate DSL, 2nd generation
shdsl (169), -- Multirate HDSL2
...
}
Note that the ifFixedLengthGroup from RFC 2863 [RFC2863] MUST be
supported and that the ifRcvAddressGroup does not apply to this MIB.
3.1.2 Usage of ifTable
The MIB branch identified by this ifType contains tables appropriate
for this interface type. Most such tables extend the ifEntry table,
and are indexed by ifIndex. For interfaces in systems implementing
this MIB, those table entries indexed by ifIndex MUST be persistent.
The following attributes are part of the mandatory ifGeneral group in
RFC 2863 [RFC2863], and are not duplicated in the HDSL2/SHDSL Line
MIB.
===================================================================
ifIndex Interface index.
ifDescr See interfaces MIB [RFC2863].
ifType hdsl2(168) or shdsl(169).
ifSpeed Set as appropriate.
(This is fixed at 1552000 for HDSL2
lines)
ifPhysAddress This object MUST have an octet string
with zero length.
ifAdminStatus See interfaces MIB [RFC2863].
ifOperStatus See interfaces MIB [RFC2863].
ifLastChange See interfaces MIB [RFC2863].
ifName See interfaces MIB [RFC2863].
ifLinkUpDownTrapEnable Default to enabled(1).
ifHighSpeed Set as appropriate.
(For HDSL2 lines, this is fixed at 2)
ifConnectorPresent Set as appropriate.
===================================================================
Figure 1: Use of ifTable Objects
3.2 IANA Considerations
The HDSL2-SHDSL-LINE-MIB module requires the allocation of a single
object identifier for its MODULE-IDENTITY. The IANA has allocated
this object identifier in the transmission subtree (48), defined in
the SNMPv2-SMI MIB module.
4. Conventions used in the MIB
4.1 Naming Conventions
A. xtuC refers to a central site terminal unit;
H2TU-C for HDSL2, or STU-C for SHDSL.
B. xtuR refers to a remote site terminal unit;
H2TU-R for HDSL2, or STU-R for SHDSL.
C. xtu refers to a terminal unit; either an xtuC or xtuR.
D. xru refer to a regenerator unit;
H2RU for HDSL2, or SRU for SHDSL.
E. xU refers to any HDSL2/SHDSL unit; either an xtu or xru.
F. CRC is cyclic redundancy check [G.991.2].

topology in the MIB (further discussed in the following section) and
to define the behavior of the statistics to be maintained by an
agent.
o Hdsl2ShdslUnitId:
Attributes with this syntax uniquely identify each unit in a
HDSL2/SHDSL span. It mirrors the EOC addressing mechanism:
xtuC(1) - CO terminal unit
xtuR(2) - CPE terminal unit
xru1(3) .. xru8(10) - regenerators, numbered from
central office side
o Hdsl2ShdslUnitSide:

o Hdsl2ShdslPerfCurrDayCount:
Attributes with this syntax define the behavior of the 1-day (24
hour) gauges found in the MIB.

hour) interval counters found in the MIB.
o Hdsl2ShdslPerfTimeElapsed: Attributes with this syntax define the
behavior of the elapsed time counters found in the MIB.
o Hdsl2ShdslPerfIntervalThreshold:
Attributes with this syntax define the behavior of the alarm
thresholds found in the MIB.

2.2. Changes to RFC 3276 Textual Conventions 4.4 Counters, Interval Buckets and Thresholds
The textual convention, Hdsl2ShdslWirePair, is found in RFC3276: For SNR Margin, Loop Attenuation, ES, SES, CRC anomalies, LOSW, and
UAS, there are event counters, current 15-minute and 0 to 96
15-minute history bucket(s) of "interval-counters", as well as
current and 0 to 30 previous 1-day interval-counter(s). Each current
15-minute event bucket has an associated threshold notification.
Hdsl2ShdslWirePair ::= TEXTUAL-CONVENTION Unlike RFC 3593 [RFC3593] and RFC 2662 [RFC2662], there is no
representation in the MIB for invalid buckets. In those cases where
the data for an interval is suspect or known to be invalid, the agent
MUST NOT report the interval. If the current 15-minute event bucket
is determined to be invalid, notifications based upon the value of
the event bucket MUST NOT be generated.
Not reporting an interval will result in holes in the associated
table. For example, the table, hdsl2Shdsl15MinIntervalTable, is
indexed by { ifIndex, hdsl2ShdslInvIndex, hdsl2ShdslEndpointSide,
hdsl2ShdslEndpointWirePair, hdsl2Shdsl15MinIntervalNumber}. If
interval 12 is determined to be invalid but intervals 11 and 13 are
valid, a Get Next operation on the indices .1.1.1.1.11 would return
indices .1.1.1.1.13.
There is no requirement for an agent to ensure a fixed relationship
between the start of a fifteen minute interval 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 the start of a day.
Counters are not reset when an xU is reinitialized, only when the
agent is reset or reinitialized (or under specific request outside
the scope of this MIB).
4.5 Profiles
As a managed node can handle a large number of xUs, (e.g., hundreds
or perhaps thousands of lines), provisioning every parameter on every
xU may become burdensome. Moreover, most lines are provisioned
identically with the same set of parameters. To simplify the
provisioning process, this MIB makes use of profiles. A profile is a
set of parameters that can be shared by multiple lines using the same
configuration.
The following profiles are used in this MIB:
o Span Configuration Profiles - Span configuration profiles contain
parameters for configuring HDSL2/SHDSL spans. They are defined in
the hdsl2ShdslSpanConfProfileTable. Since span configuration
parameters are only applicable for SHDSL, the support for span
configuration profiles are optional for HDSL2 interfaces.
Note that the configuration of the span dictates the behavior for
each individual segment end point in the span. If a different
configuration is provisioned for any given segment end point
within the span, the new configuration for this segment end point
will override the span configuration for this segment end point
only.
o Segment Endpoint Alarm Configuration Profiles - These profiles
contain parameters for configuring alarm thresholds for HDSL2/
SHDSL segment endpoints. These profiles are defined in the
hdsl2ShdslEndpointAlarmConfProfileTable.
The index value for this profile is a locally-unique
administratively assigned name for the profile having the textual
convention 'SnmpAdminString' (RFC 3411 [RFC3411]).
One or more lines may be configured to share parameters of a single
profile (e.g., hdsl2ShdslEndpointAlarmConfProfile = 'silver') by
setting its hdsl2ShdslEndpointAlarmConfProfile objects to the value
of this profile. If a change is made to the profile, all lines that
refer to it will be reconfigured to the changed parameters. Before a
profile can be deleted or taken out of service it must be first
unreferenced from all associated lines.
Implementations MUST provide a default profile whose name is 'DEFVAL'
for each profile type. The values of the associated parameters will
be vendor specific unless otherwise indicated in this document.
Before a line's profiles have been set, these profiles will be
automatically used by setting hdsl2ShdslEndpointAlarmConfProfile and
hdsl2ShdslSpanConfProfile to 'DEFVAL' where appropriate. This
default profile name, 'DEFVAL', is considered reserved in the context
of profiles defined in this MIB.
Profiles are created, assigned, and deleted dynamically using the
profile name and profile row status in each of the four profile
tables.
Profile changes MUST take effect immediately. These changes MAY
result in a restart (hard reset or soft restart) of the units on the
line.
4.6 Notifications
The ability to generate the SNMP notifications coldStart/WarmStart
(per [RFC2863]) which are per agent (e.g., per Digital Subscriber
Line Access Multiplexer, or DSLAM, in such a device), and linkUp/
linkDown (per [RFC2863]) which are per interface (i.e., HDSL2/SHDSL
line) is required.
A linkDown notification MAY be generated whenever any of ES, SES, CRC
Anomaly, LOSW, or UAS event occurs. The corresponding linkUp
notification MAY be sent when all link failure conditions are
cleared.
The notifications defined in this MIB are for initialization failure
and for the threshold crossings associated with the following events:
ES, SES, CRC Anomaly, LOSW, and UAS. Each threshold has its own
enable/threshold value. When that value is 0, the notification is
disabled.
The hdsl2ShdslEndpointCurrStatus is a bitmask representing all
outstanding error conditions associated with a particular Segment
Endpoint. Note that since status of remote endpoints is obtained via
the EOC, this information may be unavailable for units that are
unreachable via EOC during a line error condition. Therefore, not
all conditions may always be included in its current status.
Notifications corresponding to the bit fields in this object are
defined.
Two alarm conditions, SNR Margin Alarm and Loop Attenuation Alarm,
are organized in a manner slightly different from that implied in the
EOC specifications. In the MIB, these alarm conditions are tied to
the two thresholds hdsl2ShdslEndpointThreshSNRMargin and
hdsl2ShdslEndpointThreshLoopAttenuation found in the
hdsl2ShdslEndpointAlarmConfProfileTable. In the EOC, the alarm
conditions associated with these thresholds are per-unit. In the
MIB, these alarm conditions are per-endpoint. For terminal units,
this has no impact. For repeaters, this implies an implementation
variance where the agent in the terminal unit is responsible for
detecting a threshold crossing. As the reporting of a repeater
detected alarm condition to the polling terminal unit occurs in the
same EOC message as the reporting of the current SNR Margin and Loop
Attenuation values, it is anticipated that this will have very little
impact on agent implementation.
A threshold notification occurs whenever the corresponding current
15-minute interval error counter becomes equal to, or exceeds the
threshold value. One notification may be sent per interval per
interface. Since the current 15-minute counter is reset to 0 every
15 minutes, and if the condition persists, the notification may recur
as often as every 15 minutes. For example, to get a notification
whenever a "loss of" event occurs (but at most once every 15
minutes), set the corresponding threshold to 1. The agent will
generate a notification when the event originally occurs.
Note that the Network Management System, or NMS, may receive a
linkDown notification, as well, if enabled (via
ifLinkUpDownTrapEnable [RFC2863]). At the beginning of the next 15
minute interval, the counter is reset. When the first second goes by
and the event occurs, the current interval bucket will be 1, which
equals the threshold, and the notification will be sent again.
A hdsl2ShdslSpanInvalidNumRepeaters notification may be generated
following completion of the discovery phase if the number of
repeaters discovered on the line differs from the number of repeaters
specified in hdsl2ShdslSpanConfNumRepeaters. For those conditions
where the number of provisioned repeaters is greater than those
encountered during span discovery, all table entries associated with
the nonexistent repeaters are to be discarded. For those conditions
where the number of provisioned repeaters is less than those
encountered during span discovery, additional table entries are to be
created using the default span configuration profile.

DESCRIPTION
"This MIB module defines a collection of objects for managing
HDSL2/SHDSL lines. An agent may reside at either end of the
line, however the MIB is designed to require no management
communication between the modems beyond that inherent in the
low-level EOC line protocol as defined in ANSI T1E1.4/2000-006
(for HDSL2 lines), or in ITU G.991.2 (for SHDSL lines)."

DESCRIPTION DESCRIPTION
"This is the referenced pair of wires in a HDSL2/SHDSL Segment. "A gauge associated with interface performance measurements in
HDSL2 only supports a single pair (wirePair1), while SHDSL a current 1-day (24 hour) measurement interval.
supports an optional second pair (wirePair2)."
The value of this gauge starts at zero at the beginning of an
interval and is increased when associated events occur, until
the end of the 1-day interval. At that time the value of the
gauge is stored in the previous 1-day history interval, as
defined in a companion object of type
Hdsl2Shdsl1DayIntevalCount, and the current interval gauge
is restarted at zero.
In the case where the agent has no valid data available for
this interval the corresponding object instance is not
available and upon a retrieval request a corresponding error
message shall be returned to indicate that this instance does
not exist. Please note that zero is a valid value."

4. Security Considerations 8. Security Considerations
In addition to the security considerations presented in RFC3276, Blocking unauthorized access to the HDSL2-SHDSL MIB via the element
it is conceivable that a management application could be broken management system is outside the scope of this document. It should
by a G.SHDSL.bis agent which reports objects for additional be noted that access to the MIB permits the unauthorized entity to
wire pairs (as noted in section 3). modify the profiles 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 SES
thresholds.
There are a number of managed objects in this MIB that may be
considered to contain sensitive information. 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.
These identifying objects in the inventory group are:
- hdsl2ShdslInvVendorID
- hdsl2ShdslInvVendorModelNumber
- hdsl2ShdslInvVendorSerialNumber
- hdsl2ShdslInvVendorEOCSoftwareVersion
- hdsl2ShdslInvStandardVersion
- hdsl2ShdslInvVendorListNumber
- hdsl2ShdslInvVendorIssueNumber
- hdsl2ShdslInvVendorSoftwareVersion
- hdsl2ShdslInvEquipmentCode
- hdsl2ShdslInvVendorOther
- hdsl2ShdslInvTransmissionModeCapability
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.
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 3414 [RFC3414] and the
View-based Access Control Model RFC 3415 [RFC3415] are recommended.
It is then the customer/user's 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.
HDSL2-SHDSL layer connectivity from the xtuR will permit the
subscriber to manipulate both the HDSL2-SHDSL link directly and the
HDSL2-SHDSL 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.
It should be noted that interface indices in this MIB are maintained
persistently. VACM data relating to these should be stored
persistently.
There are a number of management objects defined in this MIB that
have 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.
It is conceivable that a management application that was designed to
support G.SHDSL as defined in RFC 3276 [RFC3276] could be broken by a
G.SHDSL.bis agent which reports objects for additional wire pairs (as
noted in Section 7).
For example, if a management application blindly loaded object For example, if a management application blindly loaded object
instances into an array until the an object changes (during instances into an array until the object changes (during repeated
repeated GET-NEXT requests). It is anticipated that the GET-NEXT requests). It is anticipated that the modifications to the
modifications to the management application code would be management application code would be straightforward. Perhaps of the
straightforward. Perhaps, of the form: form:
if (name[12] > 2) reject(); if ( name[12] .gt; 2 ) reject();
or or
if ( *val .gt; 4112000) reject();
if (*val > 4112000) reject(); 9. Acknowledgments
