2. The SNMP Network Management Framework
The SNMP Management Framework presently consists of five major
components:
0 An overall architecture, described in RFC 2571 [RFC2571].
0 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 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], STD 58, RFC 2579 [RFC2579] and
STD 58, RFC 2580 [RFC2580].
0 Message protocols for transferring management information. The
first version of the SNMP message protocol is called SNMPv1 and
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 in RFC 1901
[RFC1901] and RFC 1906 [RFC1906]. The third version of the
message protocol is called SNMPv3 and described in RFC 1906
[RFC1906], RFC 2572 [RFC2572] and RFC 2574 [RFC2574].
0 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 1905 [RFC1905].
o A set of fundamental applications described in RFC 2573
[RFC2573] and the view-based access control mechanism described
in RFC 2575 [RFC2575].
A more detailed introduction to the current SNMP Management Framework
can be found in RFC 2570 [RFC2570].
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 (e.g., 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.
3. 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, G.709, G.798, and
G.874 [ITU G.872][ITU G.709][ITU G.798][ITU G.874], available as of the date
this Internet-Draft.
As some of the ITU-T Recommendations have not yet been approved,
implementers of DWDM systems are advised to refer to
most recent versions of these ITU-T Recommendations.
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, 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), opticalTransport (196)
The definitions contained herein are based on the OTN
specifications in ITU-T G.872[ITU G.798], G.709 [ITU G.709],
G.798[ITU G.798], and G.874[ITU G.874].
3.1. Use of the ifTable
This section specifies how the MIB II interfaces group, as defined in
[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 [RFC1213], as extended by [RFC2863], accommodates these cases
through appropriate use of the MIB II system and interfaces groups.
The system group names and describes the type of managed resource.
The interfaces group defines which OTN layers apply and how these
layers are configured and multiplexed. This is achieved by proper
representation of OTN Layers as IfEntries as defined in [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.
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 opticalChannel IfEntries and 10 opticalChannel IfEntries, as depicted
in Figure 2. Thus,
the same 10 opticalChannel IfEntries are stacked above each of the
opticalTransport IfEntries.

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 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.

Section (OMS)
ifType opticalTransport (196)
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

no specific address associated with the
interface.)
ifAdminStatus The desired administrative status of the
interface. Supports read-only access.

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'.

ifPhysAddress The wavelength of the optical channel, expressed
in nanometers (e.g., 1550).
ifAdminStatus The desired administrative status of the
interface. Supports read-only access.
ifOperStatus The operational status of the interface. This
object is set to lowerLayerDown(7) if the
ifOperStatus of its otn interface is down(2).

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 disabled(2). Supports
read-only access.

ifAlias The (non-volatile) alias name for this interface
as assigned by the network manager.
3.4. Use of ifStackTable
Use of the ifStackTable to associate the opticalTransport and opticalChannel
interface
entries is best illustrated by the example shown in Figure 4. 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.

3.5. 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 are listed below. These terms are defined in ITU-T
Recommendations G.872, G.709, G.798, and G.874 [ITU G.798][ITU G.709]
[ITU G.798][ITU G.874].
Brief definition of some terms are also included here to
facilitate the readability of this document.
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 (ODUkP) - G.709
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
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
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 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 to 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 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 Transmitted (TxPL)
The Payload Type signal of size of one byte in the OPUk overhead
position of the source of a trail for transmission. TxPL is derived
by the equipment from the active adaptation function. If the
equipment supports multiple adaptation functions, then the
adaptation function type can be provisioned by the managing system.
Payload Type Received (AcPL)
The Payload Type signal of size of one byte recovered (received)
from the OPUk overhead position at the sink of a trail.
Payload Type Expected (ExPL)
The Payload Type signal of size of one byte to be compared with
the payload type signal received at the OPUk overhead position of
the sink for the purpose of checking the integrity of adaptation.
ExPL is derived by the equipment from the active adaptation function.
If the equipment supports multiple adaptation functions, then the
adaptation function type can be provisioned by the managing system.
Payload Type Mismatch (PLM)
The detection of 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)
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 Received (AcTI)
The Trail Trace Identifier (TTI) information recovered
(received) from the TTI overhead position at the sink of a
trail.
Trail Trace Identifier Expected (ExTI)
The Trail Trace Identifier (TTI) information, provisioned by
the managing system, to be compared with the TTI Received at
the overhead position of the sink for the purpose of checking
the integrity of connectivity.
Trace Identifier Mismatch (TIM)
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 Disabled (TimActDisabled)
The Consequent Action function of TIM is disabled.
Trace Identifier Mismatch Detection Disabled (TimDetDisabled)
The function of detecting Trace Identifier Mismatch (TIM) is
disabled.
3.5.1 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)
lof Loss of Frame (LOF)
lom Loss of Multi Frame
loop Loss of Optical Power (LOOP)
los Loss of Signal (LOS)
losO Loss of Signal - Overhead (LOS-O)
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)
3.5.2 Performance Parameters
All performance parameters are accumulated in fifteen minute
intervals and up to 96 intervals (24 hours worth) are kept by an
agent. Fewer than 96 intervals of data will be available if the
agent has been restarted within the last 24 hours. In addition,
there is a rolling 24-hour total of each performance parameter.
Performance parameters continue to be collected when the interface
is down.
There is no requirement for an agent to ensure fixed relationship
between the start of a fifteen minute interval and any wall clock;
however some agents may align the fifteen minute intervals with
quarter hours.
Performance parameters are of types PerfCurrentCount,
PerfIntervalCount and PerfTotalCount. These textual conventions are
all Gauge32, and they are used because it is possible for these
objects to decrease. Objects may decrease when Unavailable Seconds
occurs across a fifteen minutes interval boundary. See Unavailable
Seconds discussion later in this section.
3.6 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 control by:
- otnODUkTSourceMode or otnODUkTsinkMode
The Detection and corresponding action of these subfields are controlled by:
- otnODUkTTimDetDisabled
- otnODUkTTimActDisabled
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 the segment B1-B2, then used again for the 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).

6. 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.
The managed objects in this MIB contain sensitive information since,
collectively, they allow influencing of interfaces in OTN equipment
or networks and provide information of their configuration.
It is thus important to control even GET 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.
SNMPv1 by itself is not a secure environment. Even if the network
itself is secure (for example by using IPSec), 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.
It is recommended that the implementers consider the security
features as provided by the SNMPv3 framework. Specifically, the use
of the User-based Security Model RFC 2574 [RFC2574] and the View-based
Access Control Model RFC 2575 [RFC2575] is recommended.
It is then a customer/user responsibility to ensure that the SNMP
entity giving access to an instance of this MIB, 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.
