1. The Internet-Standard Management Framework

For a detailed overview of the documents that describe the current
Internet-Standard Management Framework, please refer to section 7 of
RFC 3410 [RFC3410].

Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. MIB objects are generally
accessed through the Simple Network Management Protocol (SNMP).
Objects in the MIB are defined using the mechanisms defined in the
Structure of Management Information (SMI). This memo specifies a MIB
module that is compliant to the SMIv2, which is described in STD 58,
RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
[RFC2580].

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].

2. Overview

This document describes an SNMP MIB module for managing VDSL Lines.
These definitions are based upon the specifications for VDSL as
defined in T1E1, ETSI, and ITU documentation [T1E1311, T1E1011,
T1E1013, ETSI2701, ETSI2702, ITU9931, ITU9971].

The MIB module is located in the MIB tree under MIB 2 transmission,
as discussed in the MIB-2 Integration (RFC 2863 [RFC2863]) section of
this document.

2.1. Relationship of the VDSL Line MIB Module to other MIB Modules

This section outlines the relationship of this MIB with other MIBs
described in RFCs. Specifically, IF-MIB as presented in RFC 2863
[RFC2863] is discussed.

2.1.1. General IF-MIB Integration (RFC 2863)

The VDSL 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 ifType to VDSL:

Ray & Abbi Standards Track [Page 2]

RFC 3728 VDSL-LINE MIB February 2004

IANAifType ::= TEXTUAL-CONVENTION
...

SYNTAX INTEGER {
...
vdsl(97), -- Very H-speed Digital Subscrib. Loop
...
}

Additionally, a VDSL line may contain an optional fast channel and an
optional interleaved channel which also integrate into RFC 2863
[RFC2863]. The IANA has assigned the following ifTypes to these
channels:

IANAifType ::= TEXTUAL-CONVENTION
...
SYNTAX INTEGER {
...
interleave (124), -- Interleave channel
fast (125), -- Fast channel
...
}

2.1.2. Usage of ifTable

The MIB branch identified by this ifType contains tables appropriate
for this interface type. Most 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 VDSL Line MIB.

===================================================================
ifIndex Interface index.

ifDescr See interfaces MIB [RFC2863].

ifType vdsl(97),
interleave(124), or
fast(125)

ifSpeed Set as appropriate.

ifPhysAddress This object MUST have an octet string
with zero length.

ifAdminStatus See interfaces MIB [RFC2863].

Ray & Abbi Standards Track [Page 3]

RFC 3728 VDSL-LINE MIB February 2004

ifOperStatus See interfaces MIB [RFC2863].

ifLastChange See interfaces MIB [RFC2863].

ifName See interfaces MIB [RFC2863].

ifHighSpeed Set as appropriate.

ifConnectorPresent Set as appropriate.

ifLinkUpDownTrapEnable Default to enabled(1).

2.2.2. Textual Conventions

The following textual conventions are defined to reflect the line
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 VdslLineCodingType :

Attributes with this syntax identify the line coding used. Specified
as an INTEGER, the three values are:

other(1) -- none of the following
mcm(2) -- Multiple Carrier Modulation
scm(3) -- Single Carrier Modulation

o VdslLineEntity :

Attributes with this syntax reference the two sides of a line.
Specified as an INTEGER, the two values are:

vtuc(1) -- central site transceiver
vtur(2) -- remote site transceiver

2.3 Structure

The MIB is structured into the following MIB groups:

o vdslGroup :

This group supports all line code independent MIB objects found in
this MIB. The following tables contain objects permitted for ifType
vdsl(97):

- vdslLineTable
- vdslPhysTable
- vdslPerfDataTable
- vdslPerfIntervalTable
- vdslPerf1DayIntervalTable
- vdslLineConfProfileTable
- vdslLineAlarmConfProfileTable

Ray & Abbi Standards Track [Page 5]

RFC 3728 VDSL-LINE MIB February 2004

The following tables contain objects permitted for ifTypes
interleave(124) and (fast):

- vdslChanTable
- vdslChanPerfDataTable
- vdslChanPerfIntervalTable
- vdslChanPerf1DayIntervalTable

Figure 2, below, displays the relationship of the tables in the
vdslGroup to ifEntry (and each other):

ifEntry(ifType=97) ---> vdslLineTableEntry 1:(0 to 1)

vdslLineTableEntry ---> vdslPhysTableEntry 1:(0 to 2)
---> vdslPerfDataEntry 1:(0 to 2)
---> vdslLineConfProfileEntry 1:(0 to 1)
---> vdslLineAlarmConfProfileEntry 1:(0 to 1)

vdslPhysTableEntry ---> vdslPerfIntervalEntry 1:(0 to 96)
---> vdslPerf1DayIntervalEntry 1:(0 to 30)

ifEntry(ifType=124) ---> vdslChanEntry 1:(0 to 2)
---> vdslChanPerfDataEntry 1:(0 to 2)

ifEntry(ifType=125) ---> vdslChanEntry 1:(0 to 2)
---> vdslChanPerfDataEntry 1:(0 to 2)

vdslChanEntry ---> vdslchanPerfIntervalEntry 1:(0 to 96)
---> vdslchan1DayPerfIntervalEntry 1:(0 to 30)

Figure 2: Table Relationships

o vdslNotificationGroup :

This group contains definitions of VDSL line notifications. Section
2.6, below, presents greater detail on the notifications defined
within the MIB module.

Ray & Abbi Standards Track [Page 6]

RFC 3728 VDSL-LINE MIB February 2004

2.3.1. Line Topology

A VDSL Line consists of two units - a Vtuc (the central transceiver
unit) and a Vtur (the remote transceiver unit).

2.4. Counters, Interval Buckets and Thresholds

For Loss of Frame (lof), Loss of Link (lol), Loss of Signal (los),
and Loss of Power (lpr), Errored Seconds (ES), Severely Errored
Seconds (SES), and Unavailable Seconds (UAS) there are event
counters, current 15-minute, 0 to 96 15-minute history bucket(s), and
0 to 30 1-day history bucket(s) of "interval-counters". Each current
15-minute event bucket has an associated threshold notification.

Each of these counters uses the textual conventions defined in the
HC-PerfHist-TC-MIB [RFC3705]. The HC-PerfHist-TC-MIB defines 64-bit
versions of the textual conventions found in RFC 3593 [RFC3593].

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 a Vtu is reinitialized, only when the
agent is reset or reinitialized (or under specific request outside
the scope of this MIB module).

Ray & Abbi Standards Track [Page 7]

RFC 3728 VDSL-LINE MIB February 2004

2.5. Profiles

As a managed node can handle a large number of Vtus, (e.g., hundreds
or perhaps thousands of lines), provisioning every parameter on every
Vtu 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 module:

o Line Configuration Profiles - Line configuration profiles contain
parameters for configuring VDSL lines. They are defined in the
vdslLineConfProfileTable.

o Alarm Configuration Profiles - These profiles contain parameters
for configuring alarm thresholds for VDSL transceivers. These
profiles are defined in the vdslLineAlarmConfProfileTable.

One or more lines may be configured to share parameters of a single
profile by setting their vdslLineConfProfile 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 with an index value of
'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 vdslLineConfProfile and
vdslLineAlarmConfProfile to 'DEFVAL' where appropriate. This default
profile name, 'DEFVAL', is considered reserved in the context of
profiles defined in this MIB module.

Profiles are created, assigned, and deleted dynamically using the
profile name and profile row status in each of the ten profile tables
(nine line configuration tables and one alarm configuration table).

Profile changes MUST take effect immediately. These changes MAY
result in a restart (hard reset or soft restart) of the units on the
line.

Ray & Abbi Standards Track [Page 8]

RFC 3728 VDSL-LINE MIB February 2004

2.6. Notifications

The ability to generate the SNMP notifications coldStart/WarmStart
(per [RFC3418]) 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., VDSL
line) is required.

The notifications defined in this MIB are for initialization failure
and for the threshold crossings associated with the following events:
lof, lol, los, lpr, ES, SES, and UAS. Each threshold has its own
enable/threshold value. When that value is 0, the notification is
disabled.

A linkDown notification MAY be generated whenever any of lof, lol,
los, lpr, ES, SES, or UAS threshold crossing event (as defined in
this MIB module) occurs. The corresponding linkUp notification MAY
be sent when all link failure conditions are cleared.

The vdslPhysCurrStatus is a bitmask representing all outstanding
error conditions associated with a particular VDSL transceiver. Note
that since status of remote transceivers is obtained via the EOC,
this information may be unavailable for units that are unreachable
via the 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.

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 counters are reset to 0 every
15 minutes, 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.

DESCRIPTION
"The MIB module defining objects for the management of a pair
of VDSL transceivers at each end of the VDSL line. Each such
line has an entry in an ifTable which may include multiple
transceiver lines. An agent may reside at either end of the
VDSL line. However, the MIB is designed to require no
management communication between them beyond that inherent in
the low-level VDSL line protocol. The agent may monitor and
control this protocol for its needs.

Ray & Abbi Standards Track [Page 12]

RFC 3728 VDSL-LINE MIB February 2004

VDSL lines may support optional Fast or Interleaved channels.
If these are supported, additional entries corresponding to the
supported channels must be created in the ifTable. Thus a VDSL
line that supports both channels will have three entries in the
ifTable, one for each physical, fast, and interleaved, whose
ifType values are equal to vdsl(97), fast(125), and
interleaved(124), respectively. The ifStackTable is used to
represent the relationship between the entries.

RFC 3728 VDSL-LINE MIB February 2004

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.

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.

VDSL layer connectivity from the Vtur will permit the subscriber to
manipulate both the VDSL link directly and the VDSL 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.

Additionally, allowing write access to configuration data may allow
an end-user to increase their service levels or affect other end-
users in either a positive or negative manner. For this reason, the
following tables should be considered to contain sensitive
information:

- vdslLineTable
- vdslLineConfProfileTable
- vdslLineAlarmConfProfileTable

Individual line utilization information, available via the
performance tables, may be considered sensitive. For example, if an
end-user has a far lower line utilization during certain periods of
the day, it may indicate an empty office or residence. For these
reasons, the following tables should be considered to contain
sensitive information:

- vdslPerfDataTable
- vdslPerfIntervalTable
- vdslPerf1DayIntervalTable

Further, notifications generated by agents implementing this MIB will
contain threshold and performance information.

Ray & Abbi Standards Track [Page 71]

RFC 3728 VDSL-LINE MIB February 2004

It is thus important to control even GET access to the objects within
these tables and possibly to even encrypt the values of these objects
when sending them over the network via SNMP. Not all versions of
SNMP provide features for such a secure environment.

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).

Further, deployment of SNMP versions prior to SNMPv3 is NOT
RECOMMENDED. Instead, 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 to
the objects only to those principals (users) that have legitimate
rights to indeed GET or SET (change/create/delete) them.
