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
In this document, the term OTN (Optical Transport Network) system is
used to describe devices that are compliant with the requirements
specified in the ITU-T Recommendations G.872 [ITU-T G.872], G.709
[ITU-T G.709], G.798 [ITU-T G.798], G.874 [ITU-T G.874], and G.874.1
[ITU-T G.874.1].
The optical objects will be managed using the MIB II ifTable and
ifStackTable. Additional tables will also be supported to monitor
layer specific status and provide performance monitoring data. In
the tables, some entries are required for OTN systems only. A
Configuration (Config) table, Current Performance Monitoring (PM)
table, and Interval PM table will be maintained for the OTSn, OMSn,
OChGroup, and OCh layers on a source and sink trail termination
basis. These tables will be linked to the ifTable by using the
ifIndex that is associated with that layer.
These objects are used when the particular media being used to
realize an interface is an Optical Transport interface. At present,
this applies to these values of the ifType variable in the Internet-
standard MIB:
opticalChannel (195), opticalChannelGroup (219), opticalTransport
(196)
The definitions contained herein are based on the OTN specifications
in ITU-T G.872[ITU-T G.872], G.709 [ITU-T G.709], G.798[ITU-T G.798],
G.874[ITU-T G.874], and G.874.1 [ITU-T G.874.1].
2.1. Use of the ifTable
This section specifies how the MIB II interfaces group, as defined in
RFC 2863 [RFC2863], is used for optical interfaces. Only the
ifGeneralInformationGroup will be supported for the ifTable and the
ifStackTable to maintain the relationship between the various layers.
The OTN layers are managed in the ifTable using IfEntries that
correlate to the layers depicted in Figure 1.
For example, a DWDM device with an Optical Network Node Interface
(ONNI) will have an Optical Transmission Section (OTS) physical
layer, an Optical Multiplex Section (OMS) layer (transports multiple
optical channels), and an Optical Channel (OCh) layer. There is a
one to one relationship between the OMS and OTS layers. The OMS
layer has fixed connectivity via the OTS and thus no connectivity
flexibility at the OMS layer is supported.
A device with an ONNI that does not multiplex would consist of the
OTS and OCh layers supporting a single channel.
MIB-II (RFC 1213) [RFC1213], as amended and extended by RFC 3418
[RFC3418], RFC 2863 [RFC2863], and RFC 2864 [RFC2864], accommodates
these cases through appropriate use of the system and interfaces
groups. The system group names and describes the type of managed
resource. The interfaces group defines which OTN layers exist and
how these layers are configured and multiplexed. This is achieved by
proper representation of OTN Layers as IfEntries as defined in RFC
2863 [RFC2863], as follows.
In the following figures, opticalChannel and opticalTransport are
abbreviated as och and otn respectively.

Figure 1: OTN Layers
Since the OMSn and OTSn layers have a one to one relationship, only
one otn IfEntry is required to support these two layers. Therefore,
each opticalChannel IfEntry may be mapped to m opticalTransport
IfEntries, where m is greater than or equal to 1. Conversely, each
opticalTransport entry may be mapped to n opticalChannel IfEntries,
where n is greater than or equal to 1.
There are implementations that have banded amplifers that operate on
a group of optical channels separately (e.g., C and L band channels)
before finally muxing them together and transporting them over a
physical layer. For such DWDM system implementations, it is
important to have the ability to model each of the groups (or bands)
with an ifIndex and measure the pre-OTN PM parameters for each band
separately.
The OTN layering, as described in Figure 1, can be extended to
accomodate such implementations by introducing another layer called
the OChGroup Layer.
As an example, Figure 2 depicts the OTN layering of a DWDM system
with 80 C-band and 80 L-band channels combined into their respective
channel band groups before being muxed into the OMS and transported
over the OTS.

Figure 2: OTN Layers for a Banded Configuration
If an implementation does not wish to model the banded configuration,
the OChGroup layer is absent and the OTN layering model degenerates
to the description in Figure 1. In other words, when there is an
amplifier that covers the whole band, the optIfOMSn objects should be
used, rather than using the optIfOChGroup objects with a degenerate
group that covers all channels.
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 xxxDirectionality 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 (i.e., instances of optIfOTSnDirectionality and
optIfOMSnDirectionality that correspond to a given ifIndex value must
have the same value, and instances of optIfOChDirectionality,
optIfOTUkDirectionality, and optIfODUkDirectionality that correspond
to a given ifIndex value must have the same value).
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
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.
Example 1: Management of unterminated opticalChannel (och) using
passive optics
An OTN device connected with two adjacent nodes in a single fiber
ring that supports 10 wavelengths per fiber would have 2
opticalTransport IfEntries and 20 opticalChannel IfEntries, as
depicted in Figure 3. Thus 10 opticalChannel IfEntries are
stacked above the first opticalTransport IfEntry, and the other 10
opticalChannel IfEntries are stacked above the second
opticalTransport IfEntry. Note that the optical channels in this
example are un-terminated, and thus no OTUk objects will be
instantiated for these optical channels. The opticalChannel
IfEntries of one otn may be dropped/added from/to the OTN device
or cross-connected with the opticalChannel IfEntries of the other
otn. Cross-connection from a member of the first 10
opticalChannel IfEntries to a member of the second 10
opticalChannel IfEntries could be modelled by using a cross-
connect object, which is not yet defined in this version of the
MIB.

Example 2: Management of terminated opticalChannel (och) interfaces
An OTN device connected with two adjacent nodes in a single fiber
ring that supports 10 wavelengths per fiber would have 2
opticalTransport IfEntries and 20 opticalChannel IfEntries, as
depicted in Figure 4. Thus 10 opticalChannel IfEntries are
stacked above the first opticalTransport IfEntry, and the other 10
opticalChannel IfEntries are stacked above the second
opticalTransport IfEntry. As the optical channels in this example
are terminated, OTUk objects and possibly ODUk objects will be
instantiated for the terminated opticalChannel IfEntries.

Figure 4: Interface stacks when channels are terminated
Note that the two examples described above depict the interface
stacks when the banded configuration is not modeled.
The exact configuration and multiplexing of the layers is maintained
in the ifStackTable (RFC 2863) [RFC2863] and in the ifInvStackTable
(RFC 2864) [RFC2864]; see section 2.5 for details.

illustrated by the example shown in Figure 5. The example assumes an
otn 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.

Figure 6 illustrates an example for a banded configuration. The
example assumes an otn interface with ifIndex i that carries two
multiplexed och groups with ifIndex values u and v. An och group
with ifIndex value u combines two och interfaces with ifIndex values
of a and b. An och group with ifIndex value v combines two och
interfaces with ifIndex values of c and d. The example show that a
and b are stacked above (i.e., multiplexed into) u. Likewise, c and
d are stacked above v. u and v are multiplexed into i. Furthermore,
it shows that there is no layer lower than i and no layer higher than
a, b, c, and/or d. It also shows that u has a and b as its higher
layers, and v has c and d as its higher layers.

interfaces reversed.
2.6. Optical Network Terminology
The terminology used in this document to describe the layers of an
optical network and the error conditions and performance monitoring
parameters on an optical circuit as monitored by an optical system is
listed below. These terms are defined in ITU-T Recommendations G.872
[ITU-T G.872], G.709 [ITU-T G.709], G.798 [ITU-T G.798], G.874 [ITU-T
G.874], G.874.1 [ITU-T G.874.1], and G.806 [ITU-T G.806]. Brief
definitions of some terms are also included here to facilitate the
readability of this document.
Degraded Threshold (DEGTHR) - G.806
A threshold level for declaring a performance monitoring (PM)
Second (a time period of one second) to be bad. A PM Second is
declared bad if the percentage of detected errored blocks in
that second or the number of errored blocks in that Second is
greater than or equal to DEGTHR.
DEGM - G.806
A threshold level for declaring a Degraded Signal defect
(dDEG). A dDEG shall be declared if DEGM consecutive bad PM
Seconds are detected.
Expected Destination Access Point Identifier (ExDAPI) - G.798
The Expected Destination Access Point Identifier (ExDAPI),
provisioned by the managing system, to be compared with the TTI
accepted at the overhead position of the sink for the purpose
of checking the integrity of connectivity.
Expected Source Access Point Identifier (ExSAPI) - G.798
The Expected Source Access Point Identifier (ExSAPI),
provisioned by the managing system, to be compared with the TTI
accepted at the overhead position of the sink for the purpose
of checking the integrity of connectivity.
Inter-Domain Interface (IrDI) - G.872
A physical interface that represents the boundary between two
administrative domains.
G.709 defines the requirements for the IrDI at the Network Node
Interface (NNI).
Intra-Domain Interface (IaDI) - G.872
A physical interface within an administrative domain.
Optical Channel Layer Network (OCh) - G.872
This layer network provides end-to-end networking of optical
channels for transparently conveying client information of
varying format (e.g., SDH STM-N, PDH 565 Mbit/s, cell based
ATM, etc.).
Optical Channel Data Unit Path Layer Network (ODUk) - G.709/Y.1331
This layer network provides functionality for the transport of
information structure consisting of the information payload
(OPUk) and the related overhead for management of an optical
channel.
Optical Channel Data Unit Tandem Connection Sub-Layer Network (ODUkT)
- G.709/Y.1331
This layer network is a sub-layer of the optical data unit
layer, which provides the capability for tandem connection
monitoring. One to six nested levels of monitoring are defined
for OTN.
Optical Channel Payload Unit (OPUk) - G.709/Y.1331
The OPUk is the information structure used to adapt client
information for transport over an optical channel. OPUk
capacities for k=1, k=2, k=3 are defined in ITU-T. The index
"k" is used to represent different versions of OPUk, ODUk and
OTUk. k=1 represents an approximate bit rate of 2.5 Gbit/s,
k=2 represents an approximate bit rate of 10 Gbit/s, and k=3
represents an approximate bit rate of 40 Gbit/s.
Optical Multiplex Section Layer Network (OMS) - G.872
This layer network provides functionality for networking of a
multi-wavelength optical signal. Note that a "multi-
wavelength" signal includes the case of just one optical
channel.
Optical Transport Module (OTM-n[r].m) - G.872
The OTM is the information structure that is transported across
an ONNI. The index n and m define the number of supported
wavelengths and bit rates at the interface.
Two OTM structures are defined: OTM with full functionality
(OTM-n.m) and OTM with reduced functionality (OTM-0.m & OTM-
nr.m).
The OTM-n.m consists of up to n multiplexed optical channels
and an OTM overhead signal to support the non-associated
overhead. The OTM-0 consists of a single optical channel
without a specific color assigned. The OTM-nr.m consists of up
to n multiplexed optical channels. Non associated overhead is
not supported.
Optical Transport Network (OTN) - G.872
A transport network bounded by optical channel access points.
The optical transport network layered structure is comprised of
the optical channel, optical multiplex section and optical
transmission section layer networks.
According to G.872, an OTN-compliant interface is an interface
of the optical transport network based on the architecture
defined in G.872, while an OTN-non-compliant interface is an
interface that does not comply with the interface
recommendations that will be defined for the optical transport
network based on the architecture defined in G.872.
Optical Transmission Section Layer Network (OTS) - G.872
This layer network provides functionality for transmission of
optical signals on optical media of various types.
Optical Channel Transport Unit Section Layer Network (OTUk) - G.709
The OTUk is the layer network that provides for the transport
of an ODUk over one or more optical channel link connections.
It consists of the optical channel data unit and OTUk related
overhead (FEC and overhead for management of an optical channel
link connection). It is characterized by its frame structure,
bit rate, and bandwidth.
Payload Type Mismatch (PLM)
The detection of a mismatch of payload type is based on a
comparison between the expected Payload Type signal,
provisioned via the management interface, and the received
Payload Type signal.
Trail Trace Identifier Transmitted (TxTI) - G.798
The Trail Trace Identifier (TTI) information, provisioned by
the managing system, to be placed in the TTI overhead position
of the source of a trail for transmission.
Trail Trace Identifier Accepted (AcTI) - G.798
The Trail Trace Identifier (TTI) information accepted from the
TTI overhead position at the sink of a trail.
Trail Trace Identifier Accepted Status (AcTIStatus) - G.798
The Status of the Trail Trace Identifier (TTI) accepted from
the TTI overhead position at the sink of a trail.
Trace Identifier Mismatch (TIM) - G.798
The detection of TIM is based on a comparison between the
expected Trial Trace Identifier (TTI), configured via the
management interface, and the received TTI.
Trace Identifier Mismatch Consequent Action Enabled (TimActEnabled) -
G.798
The Consequent Action function of TIM is disabled.
Trace Identifier Mismatch Detection Mode (TimDetMode) - G.798
The mode of detecting Trace Identifier Mismatch (TIM).
Possible modes are:
(1) off - no checking,
(2) SAPI - checking the SAPI only,
(3) DAPI - checking the DAPI only, and
(4) Both - checking both the SAPI and DAPI.
2.6.1. Defect Conditions
The following Defect conditions are defined in G.798 (as fault cause)
for OTN monitoring.
ais Alarm Indication Signal (AIS)
bdi Backward Defect Indication (BDI)
bdiO Backward Defect Indication - Overhead (BDI-O)
bdiP Backward Defect Indication - Payload (BDI-P)
deg Degraded (DEG)
lck Locked (LCK)

losP Loss of Signal - Payload (LOS-P)
oci Open Connection Indication (OCI)
plm Payload Mismatch (PLM)
ssf Server Signal Failure (SSF)
ssfO Server Signal Failure - Overhead (SSF-O)
ssfP Server Signal Failure - Payload (SSF-P)
tim Trace Identifier Mismatch (TIM)
The relationship of these conditions within a network layer and
between layers are described in G.798 [ITU-T G.798].
2.6.2. Performance Parameters
To facilitate identification of equipment and facilities that may
require maintenance, it is necessary to monitor parameters such as
optical power at each layer. The measurements are taken
periodically, and a snapshot of the current value is also made
available. More specifically, performance parameters at each layer
are maintained for the current 15-minute interval, the current 24-
hour interval, N previous 15-minute intervals where 4 <= N <= 96, and
one previous 24-hour interval.
Note that some of the previous interval data will be unavailable if
the agent has restarted within the last 24 hours.
There is no requirement for an agent to ensure a fixed relationship
between the start of a 15-minute or 24-hour interval and any wall
clock; however, some agents may align the 15-minute intervals with
quarter hours and may align the 24-hour intervals with a particular
hour of the day (e.g., 00:00 UTC).
Note that some DWDM systems may also monitor the laser temperature of
the equipment in addition to monitoring the optical power. However,
industry opinions vary widely with respect to laser temperature
monitoring, in particular regarding the benefit of the monitoring and
which temperatures are to be monitored (i.e., all or only some of the
pump lasers). Similarly, there are varying opinions regarding mid-
stage power monitoring. Since no consensus was reached, it was
decided that the laser temperature monitoring and mid-stage
monitoring would not be standardized in the MIB. If an
implementation would like to monitor these parameters, one could use
a proprietary MIB or the ENTITY-SENSOR-MIB [RFC3433] to capture this
information.
The sink-side monitoring points for the various layers are shown in
Figure 7 below.

Note that optical performance parameters are of type Integer32,
rather than Counter32 or Gauge32, because it is possible for these
objects to increase or decrease and to assume negative or positive
values.
2.7. Tandem Connection Monitoring (TCM)
An ODUk termination can be provisioned to support (0..6) TCM levels.
Each TCM field contains the following subfields:
- Trail Trace Identifier (TTI)
- Bit Interleaved Parity 8 (BIP8)
- Backward Defect Indication (BDI)
- Backward Error Indication (BEI)
- Status bits indicating the presence of TCM overhead, Incoming
AlignmentError, or a maintenance signal (STAT).
The insertion of these subfields is controlled by:
- optIfODUkTSourceMode or otnODUkTsinkMode
The detection and corresponding action of these subfields are
controlled by:
- optIfODUkTTimDetMode
- optIfODUkTTimActEnabled
The TCM connection is used for monitoring the quality of an end to
end connection or any segment, as illustrated in the example:
TCM1 used for the end-to-end connection from A1 to A2.
TCM2 used for segment B1-B2, then used again for segment B3-B4.
TCM3-TCM6 these bytes are not in used in this example.
The TCM connection can be nested (B1-B2 is nested in A1-A2) or
cascaded (B1-B2 and B3-B4).
