Abstract
This memo defines a module of the Management Information Base (MIB)
used by Simple Network Management Protocol (SNMP) in TCP/IP- based
internet. In particular, it defines objects for managing Optical
parameters associated with Dense Wavelength Division Multiplexing
(DWDM) interfaces. This is an extension of the RFC3591 to support
the optical parameters described in ITU-T G.698.2. [ITU.G698.2]
The MIB module defined in this memo can be used for Optical
Parameters monitoring and/or configuration of the endpoints of Black
Links.

Internet-Draft draft-galikunze-ccamp-g-698-2-snmp-mib-03 July 2013
This memo defines a portion of the Management Information Base (MIB)
used by Simple Network Management Protocol (SNMP) in TCP/IP- based
internets. In particular, it defines objects for managing Optical
parameters associated with Wavelength Division Multiplexing (WDM)
systems in accordance with the optical interface defined in G.698.2
[ITU.G698.2]
Black Link approach allows supporting an optical transmitter/receiver
pair of one vendor to inject a DWDM channel and run it over an
optical network composed of amplifiers, filters, add-drop
multiplexers from a different vendor. From architectural point of
view, the "Black Link" is a set of pre-configured/qualified network
connections between the G.698.2 reference points S and R. The black
links will be managed at the edges (i.e. the transmitters and
receivers attached to the S and R reference points respectively) for
the relevant parameters specified in G.698.2 [ITU.G698.2], G.798
[ITU.G798], G.874 [ITU.G874], and the performance parameters
specified G.7710/Y.1701 [ITU-T G.7710] and and G.874.1 [ITU.G874.1].
The G.698.2 [ITU.G698.2] provides optical parameter values for
physical layer interfaces of Dense Wavelength Division Multiplexing
(DWDM) systems primarily intended for metro applications which
include optical amplifiers. Applications are defined in G.698.2
[ITU.G698.2] using optical interface parameters at the single-channel
connection points between optical transmitters and the optical
multiplexer, as well as between optical receivers and the optical
demultiplexer in the DWDM system. This Recommendation uses a
methodology which does not specify the details of the optical link,
e.g. the maximum fibre length, explicitly. The Recommendation
currently includes unidirectional DWDM applications at 2.5 and 10
Gbit/s (with 100 GHz and 50 GHz channel frequency spacing). Work is
still underway for 40 and 100 Gbit/s interfaces. There is
possibility for extensions to a lower channel frequency spacing.
This document specifically refers to the "application code" defined
in the G.698.2 [ITU.G698.2] plus few optical paramenter not included
in the application code definition.
This draft refers and supports also the draft-kunze-g-698-2
-management-control-framework
The building of an SNMP MIB describing the optical parameters defined
in G.698.2 [ITU.G698.2] G.798 [ITU.G798], G.874 [ITU.G874],
parameters specified G.7710/Y.1701 [ITU-T G.7710] allows the
different vendors and operator to retrieve, provision and exchange
information related to Optical blak links in a standardized way.
This facilitates interworking in case of using optical interfaces
from different vendors at the end of the link.
G.Galimberti, et al. Expires January 16, 2014 [Page 3]
Internet-Draft draft-galikunze-ccamp-g-698-2-snmp-mib-03 July 2013
The MIB, reporting the Optical parameters and their values,
characterizes the features and the performances of the optical
components and allow a reliable black link design in case of
multivendor optical networks.
Although RFC 3591 [RFC3591] describes and defines the SNMP MIB of a
number of key optical parameters, alarms and Performance Monitoring,
a more complete description of optical parameters and processes can
be found in the ITU-T Recommendations. Appendix A of this document
provides an overview about the extensive ITU-T documentation in this
area. The same considerations can be applied to the RFC 4054
[RFC4054]
2. 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].
3. Conventions
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 RFC 2119 [RFC2119] In
the description of OIDs the convention: Set (S) Get (G) and Trap (T)
conventions will describe the action allowed by the parameter.
4. Overview
Figure 1 shows a set of reference points, for the linear "black link"
approach, for single-channel connection (Ss and Rs) between
transmitters (Tx) and receivers (Rx). Here the DWDM network elements
include an OM and an OD (which are used as a pair with the opposing
element), one or more optical amplifiers and may also include one or
more OADMs.

[Fig. 5.2/G.698.2] and Bidirectional Black Link configurations [Fig.
5.3/G.698.2]
4.1. Optical Parameters Description
The black links are managed at the edges, i.e. at the transmitters
(Tx) and receivers (Rx) attached to the S and R reference points
respectively. The parameters that could be managed at the black link
edges are specified in G.698.2 [ITU.G698.2] section 5.3 referring the
"application code" notation
The definitions of the optical parameters are provided below to
increase the readability of the document, where the definition is
ended by (G) the parameter can be retrieve with a GET, when (S) it
can be provisioned by a SET, (G,S) can be either GET and SET.

Internet-Draft draft-galikunze-ccamp-g-698-2-snmp-mib-03 July 2013
To support the management of these parameters, the SNMP MIB in RFC
3591 [RFC3591] is extended with a new MIB module defined in section 6
of this document. This new MIB module includes the definition of new
configuration table of the OCh Layer for the parameters at Tx (S) and
Rx (R).
4.1.1. Rs-Ss Configuration
The Rs-Ss configuration table allows configuration of Wavelength,
Power and Application codes as described in [ITU.G698.2] and G.694.1
[ITU.G694.1]
This parameter report the current Transceiver Output power, it can be
either a setting and measured value (G, S) NEED TO DISCUSS ON THIS.
Wavelength Value (see G.694.1 Table 1):
This parameter indicates the wavelength value that Ss and Rs will
be set to work (in THz) se in particular Section 6/G.694.1 (G, S).
Vendor Transceiver Class:
Other than specifying all the Transceiver parameter, it might be
convenient for the vendors to summarize a set of parameters in a
single proprietary parameter: the Class of transceiver. The
Transceiver classification will be based on the Vendor Name and
the main TX and RX parameters (i.e. Trunk Mode, Framing, Bit rate,
Trunk Type, Channel Band, Channel Grid, Modulation Format, Channel
Modulation Format, FEC Coding, Electrical Signal Framing at Tx,
Minimum maximum Chromatic Disperion (CD) at Rx, Maximum
Polarization Mode Dispersion (PMD) at Rx, Maximum differential
group delay at Rx, Loopbacks, TDC, Pre-FEC BER, Q-factor,
Q-margin,etc.). If this parameter is used, the MIB parameters
specifying the Transceiver characteristics may not be significant
and the vendor will be responsible to specify the Class contents
and values. The Vendor can publish the parameters of its Classes
or declare to be compatible with published Classes.(G) Optional
for compliance. (not mentioned in G.698)
Number of Vendor Transceiver Class Supported
This parameter indicates the number of Vendor Transceiver codes
supported by this interface (G).
Single-channel application codes (see G.698.2):
This parameter indicates the transceiver application code at Ss
and Rs as defined in [ITU.G698.2] Chapter 5.4 - this parameter can
be called Optical Interface Identifier OII as per [draft-
martinelli-wson-interface-class] (G).
Number of Single-channel application codes Supported

4.2. Use of ifTable
This section specifies how the MIB II interfaces group, as defined in
RFC 2863 [RFC2863], is used for the link ends of a black link. Only
the ifGeneralInformationGroup will be supported for the ifTable and
the ifStackTable to maintain the relationship between the OCh and OPS
layers. The OCh and OPS layers are managed in the ifTable using
IfEntries that correlate to the layers depicted in Figure 1.
For example, a device with TX and/or RX will have an Optical Physical
Section (OPS) layer, and an Optical Channel (OCh) layer. There is a
one to n relationship between the OPS and OCh layers.
EDITOR NOTE: Reason for changing from OChr to OCh: Work on revised
G.872 in the SG15 December 2011 meeting agreed to remove OChr from
the architecture and to update G.709 to account for this
architectural change. The meeting also agreed to consent the revised
text of G.872 and G.709 at the September 2012 SG15 meeting.
Figure 2 In the following figures, opticalChannel and
opticalPhysicalSection are abbreviated as och and ops respectively.

Each opticalChannel IfEntry is mapped to one of the m
opticalPhysicalSection IfEntries, where m is greater than or equal to
1. Conversely, each opticalTransPhysicalSection port entry is mapped
to one of the n opticalChannel IfEntries, where n is greater than or
equal to 1.
The design of the Optical Interface MIB provides the option to model
an interface either as a single bidirectional object containing both
sink and source functions or as a pair of unidirectional objects, one
containing sink functions and the other containing source functions.
If the sink and source for a given protocol layer are to be modelled
as separate objects, then there need to be two ifTable entries, one
that corresponds to the sink and one that corresponds to the source,
where the directionality information is provided in the configuration
tables for that layer via the associated Directionality objects. The
agent is expected to maintain consistent directionality values
between ifStackTable layers (e.g., a sink must not be stacked in a
1:1 manner on top of a source, or vice-versa), and all protocol
layers that are represented by a given ifTable entry are expected to
have the same directionality.
When separate ifTable entries are used for the source and sink
functions of a given physical interface, association between the two
uni-directional ifTable entries (one for the source function and the
other for the sink functions) should be provided. It is recommended
G.Galimberti, et al. Expires January 16, 2014 [Page 9]
Internet-Draft draft-galikunze-ccamp-g-698-2-snmp-mib-03 July 2013
that identical ifName values are used for the two ifTable entries to
indicate such association. An implementation shall explicitly state
what mechanism is used to indicate the association, if ifName is not
used.
4.2.1. Use of ifTable for OPS Layer
Only the ifGeneralInformationGroup needs to be supported.
ifTable Object Use for OTN OPS Layer
=====================================================================
ifIndex The interface index.
ifDescr Optical Transport Network (OTN) Optical
Physical Section (OPS)
ifType opticalPhysicalSection (xxx)
<<<Editor Note: Need new IANA registration value for xxx. >>>
ifSpeed Actual bandwidth of the interface in bits per
second. If the bandwidth of the interface is
greater than the maximum value of 4,294,967,295,
then the maximum value is reported and
ifHighSpeed must be used to report the
interface's speed.
ifPhysAddress An octet string with zero length. (There is
no specific address associated with the
interface.)
ifAdminStatus The desired administrative state of the
interface. Supports read-only access.
ifOperStatus The operational state of the interface. The
value lowerLayerDown(7) is not used, since
there is no lower layer interface. This object
is set to notPresent(6) if a component is
missing, otherwise it is set to down(2) if
either of the objects optIfOPSnCurrentStatus
indicates that any defect is present.
ifLastChange The value of sysUpTime at the last change in
ifOperStatus.
ifName Enterprise-specific convention (e.g., TL-1 AID)
G.Galimberti, et al. Expires January 16, 2014 [Page 10]
Internet-Draft draft-galikunze-ccamp-g-698-2-snmp-mib-03 July 2013
to identify the physical or data entity
associated with this interface or an
OCTET STRING of zero length. The
enterprise-specific convention is intended to
provide the means to reference one or more
enterprise-specific tables.
ifLinkUpDownTrapEnable Default value is enabled(1). Supports
read-only access.
ifHighSpeed Actual bandwidth of the interface in Mega-bits
per second. A value of n represents a range of
'n-0.5' to 'n+0.499999'.
ifConnectorPresent Set to true(1).
ifAlias The (non-volatile) alias name for this interface
as assigned by the network manager.
4.2.2. Use of ifTable for OCh Layer
Use of ifTable for OCh Layer See RFC 3591 [RFC3591] section 2.4
4.2.3. Use of ifStackTable
Use of the ifStackTable and ifInvStackTable to associate the
opticalPhysicalSection and opticalChannel interface entries is best
illustrated by the example shown in Figure 3. The example assumes an
ops interface with ifIndex i that carries two multiplexed OCh
interfaces with ifIndex values of j and k, respectively. The example
shows that j and k are stacked above (i.e., multiplexed into) i.
Furthermore, it shows that there is no layer lower than i and no
layer higher than j and/or k.

7. Relationship to Other MIB Modules
7.1. Relationship to the [TEMPLATE TODO] MIB
7.2. MIB modules required for IMPORTS
8. Definitions
[TEMPLATE TODO]: put your valid MIB module here.
A list of tools that can help automate the process of
checking MIB definitions can be found at
http://www.ops.ietf.org/mib-review-tools.html
9. 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:
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.
SNMP versions prior to SNMPv3 did not include adequate security.
Even if the network itself is secure (for example by using IPsec),
G.Galimberti, et al. Expires January 16, 2014 [Page 19]
Internet-Draft draft-galikunze-ccamp-g-698-2-snmp-mib-03 July 2013
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.
10. IANA Considerations
Option #1:
The MIB module in this document uses the following IANA-assigned
OBJECT IDENTIFIER values recorded in the SMI Numbers registry:
Descriptor OBJECT IDENTIFIER value
---------- -----------------------
sampleMIB { mib-2 XXX }
Option #2:
Editor's Note (to be removed prior to publication): the IANA is
requested to assign a value for "XXX" under the 'mib-2' subtree and
to record the assignment in the SMI Numbers registry. When the
assignment has been made, the RFC Editor is asked to replace "XXX"
(here and in the MIB module) with the assigned value and to remove
this note.
Note well: prior to official assignment by the IANA, an internet
draft MUST use placeholders (such as "XXX" above) rather than actual
numbers. See RFC4181 Section 4.5 for an example of how this is done
in an internet draft MIB module.
Option #3:
This memo includes no request to IANA.
