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].
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
Expires December 12, 2003 [Page 2]
INTERNET-DRAFT VDSL-LINE MIB June 2003
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:
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 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 VDSL Line MIB.
===================================================================
ifIndex Interface index.
ifDescr See interfaces MIB [RFC2863].
ifType vdsl(97),
interleaved(124), or
fast(125)
ifSpeed Set as appropriate.

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].
ifHighSpeed Set as appropriate.

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
The following tables contain objects permitted for ifTypes
interleaved(124) and (fast):
- vdslChanTable
- vdslChanPerfDataTable
- vdslChanPerfIntervalTable
- vdslChanPerf1DayIntervalTable
Figure 2, below, displays the relationship of the tables in the
vdslGroup to ifEntry (and each other):

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.
2.3.1 Line Topology
A VDSL Line consists of two units - a Vtuc (the central tranceiver
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),
Expires December 12, 2003 [Page 6]
INTERNET-DRAFT VDSL-LINE MIB June 2003
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 [RFCXXXX]. The HC-PerfHist-TC-MIB defines 64-
--- RFC Ed: please replace XXXX with the RFC number assigned to the
--- accompanying HC-TC MIB
bit versions of the textual conventions found in RFC 2493 [RFC2493].
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).
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 its 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
Expires December 12, 2003 [Page 7]
INTERNET-DRAFT VDSL-LINE MIB June 2003
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.
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 vdslCurrStatus 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
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 counter 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
Expires December 12, 2003 [Page 8]
INTERNET-DRAFT VDSL-LINE MIB June 2003
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.
2.7 Persistence
All read-write and read-create objects defined in this MIB module
SHOULD be stored persistently. Following is an exhaustive list of
these persistent objects:

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.
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
Expires December 12, 2003 [Page 11]

interleaved(124), respectively. The ifStackTable is used to
represent the relationship between the entries.

8. Security Considerations
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.
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.
For this reason, there are a number of managed objects in this MIB
that may contain sensitive information. These are:
vdslThresh15MinLofs
vdslThresh15MinLoss
vdslThresh15MinLprs
vdslThresh15MinLols
vdslThresh15MinESs
vdslThresh15MinSESs
vdslThresh15MinUASs
It is thus important to control even GET access to these objects 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.
Further, notifications generated by agents implementing this MIB
will contain the above threshold information.
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) objects
which utilize the textual conventions defined 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 a MIB module which utilizes the textual conventions
defined in 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.
