This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited.
This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in TCP/IP-based internets. In particular, it defines objects for managing Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH) objects. This document is a companion document with Definitions of Managed Objects for the DS1/E1 and DS3/E3 Interface Types, RFC1406 [14] and RFC1407 [13].
This memo specifies a MIB module in a manner that is both compliant to the SNMPv2 SMI, and semantically identical to the peer SNMPv1 definitions.

The SNMPv2 Network Management Framework consists of four major components. They are:
RFC 1442 [1] which defines the SMI, the mechanisms used for describing and naming objects for the purpose of management.
STD 17, RFC 1213 [6] defines MIB-II, the core set of managed objects for the Internet suite of protocols. Reference [12] defines the evolution of the Interfaces Group of MIB II in terms of extensions and precise applications of the objects.
RFC 1445 [4] which defines the administrative and other architectural aspects of the framework.
RFC 1448 [5] which defines the protocol used for network access to managed objects.
The Framework permits new objects to be defined for the purpose of experimentation and evaluation.
This specification makes also use of:
RFC 1443 [2] which defines textual conventions for the specification of managed objects.
RFC 1444 [3] which defines conformance statements for the specification of managed objects.
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined using the subset of Abstract Syntax Notation One (ASN.1) [7]
defined in the SMI. In particular, each object has a name, a syntax,
and an encoding. The name is an object identifier, an
administratively assigned name, which specifies an object type. The
object type together with an object instance serves to uniquely
identify a specific instantiation of the object. For human
convenience, we often use a textual string, termed the OBJECT
DESCRIPTOR, to also refer to the object type.
The syntax of an object type defines the abstract data structure corresponding to that object type. The ASN.1 language is used for this purpose. However, the SMI RFC 1442 purposely restricts the ASN.1 constructs which may be used. These restrictions are explicitly made for simplicity.
The encoding of an object type is simply how that object type is represented using the object type's syntax. Implicitly tied to the notion of an object type's syntax and encoding is how the object type is represented when being transmitted on the network. The SMI specifies the use of the basic encoding rules of ASN.1 [8], subject to the additional requirements imposed by the SNMP.
Section 4 contains contains the specification of all object types contained in this MIB module. The object types are defined using the conventions defined in the SMI, as amended by the extensions specified in the SNMPv2 SMI.
These objects are used when the particular media being used to realize an interface is a SONET/SDH interface. At present, this applies to these values of the ifType variable in the Internet- standard MIB:
sonet (39), sonetPath (50), sonetVT (51)
The definitions contained herein are based on the SONET/SDH specifications in ANSI T1.105 and T1.106-1988 [9, 9a, 10] and CCITT G.707, 708, 709, and G.783 [15-18].
This section specifies how the MIB II interfaces group, as defined in [12], is used for SONET/SDH interfaces. The SONET/SDH layers support several multiplexing possibilities.
For example in SONET, an Synchronous Transport Signal 3 (STS-3) has 3 SONET Paths, and a STS-3c has 1 SONET Path. Another example could be a STS-12 having 4 SONET STS-3c Paths. Similarly, a SONET Synchronous Payload Envelope (SPE) can carry many Virtual Tributaries (VTs), for example, one SONET SPE can carry 28 VT1.5s. It is important to note that an SPE and a VT in SONET is collectively referred to as a Virtual Container (VC) in SDH. Also, an STS is called Synchronous Transport Module (STM) in SDH.
Not all SONET/SDH equipment terminate all SONET/SDH layers. For example, an SONET/SDH STE regenerator terminates SONET/SDH Sections only, and is transparent for all layers above that. SONET/SDH Add- Drop multiplexers and Digital Cross Connect Systems terminate SONET/SDH Lines. SONET/SDH Terminal Multiplexers may also terminate SONET/SDH Paths and VTs/VCs.
MIB II [6], as extended by [12], accommodates these cases by appropriate use of the MIB II system group, and the interfaces group. The system group can name and describe the type of managed resource. The interfaces group defines which SONET/SDH layers apply, how these layers are configured and multiplexed. This is achieved by proper representation of SONET/SDH Layers by ifEntries as defined in [12], as follows:
_____________________________
| | | | >
| | | | |
| VT 1 |..........|VT K| > K ifEntries

The terminology used in this document to describe error conditions on a SONET circuit as monitored by a SONET system are from the ANSI T1M1.3/93-005R2 [11]. The terminology used in this document to describe error conditions on a SDH circuit as monitored by a SDH system are from the CCITT G.783 [18]. Only the SONET Performance Monitoring terminology is defined in this document. The definitions for SDH Performance Monitoring terms are similar but not identical, and they can be found in [18]. If the definition in this document does not match the definition in the ANSI T1M1.3/93-005R2 draft document, the implementer should follow the definition described in this document.
Section Loss Of Frame Failure (Out of Frame Event, Severely
Errored Frame Defect)
An Out of Frame (OOF) event (or Severely Errored Frame
defect) is the occurrence of four contiguous errored
frame alignment words. A frame alignment work occupies
the A1 and A2 bytes of an STS frame, and is defined in
T1.105. The SEF defect is terminated when two contiguous
error-free frame words are detected. Any implementation
of the frame recovery circuitry which achieves
realignment following an OOF within the 250 microsecond
(two frames) interval implied by this definition is
acceptable.
An Loss of Frame (LOF) defect is declared when an OOF/SEF defect persists for a period of 3 milliseconds. The LOF defect is terminated when the incoming signal remains continuously in-frame for a period of 1 ms to 3 ms.
An LOF failure is declared when the LOF defect persists for a period of 2.5 +/- 0.5 seconds, except when an LOS defect or failure is present. The LOF failure is cleared when the LOS failure is declared, or when the LOF defect is absent for 10 +/- 0.5 seconds.
Loss of Signal
The Loss of Signal (LOS) defect is declared when no
transitions are detected on the incoming signal (before
descrambling). The LOS defect is detected upon
observing 2.3 to 100 microseconds of no transitions. The
LOS defect is cleared after a 125 microsecond interval
(one frame) during which no LOS defect is detected.
The LOS failure is declared when the LOS defect persists for a period of 2.5 +/- 0.5 seconds, or if LOS defect is
present when the criteria for LOF failure declaration have been met. The LOS failure is cleared when the LOS defect is absent for a period of 10 +/- 0.5 seconds. Declaration of LOS failure clears any existing LOF failure. Clearing the LOS failure allows immediate declaration of the LOF failure if conditions warrant.
STS-Path Loss of Pointer
An Loss of Pointer (LOP) defect is declared when either a
valid pointer is not detected in eight consecutive
frames, or when eight consecutive frames are detected
with the New Data Flag (NDF) set to "1001" without a
valid concatenation indicator (see ANSI T1.105). A LOP
defect is terminated when either a valid pointer with a
normal NDF set to "0110", or a valid concatenation
indicator is detected for three contiguous frames.
Incoming STS-Path AIS shall not result in the declaration
of a LOP defect.
A STS-Path LOP failure is declared when the STS-Path LOP defect persists for a period of 2.5 +/- 0.5 seconds. A STS-Path LOP failure is cleared when the STS-Path LOP defect is absent for 10 +/- 0.5 seconds.
VT Loss of Pointer
A VT LOP defect is declared when either a valid pointer
is not detected in eight consecutive VT superframes, or
when eight consecutive VT superframes are detected with
the NDF set to "1001" without a valid concatenation
indicator. A VT LOP defect is terminated when either a
valid pointer with a normal NDF set to "0110", or a valid
concatenation indicator is detected for three contiguous
VT superframes. Incoming VT-Path AIS shall not result in
declaring a VT LOP defect.
A VT LOP failure is declared when the VT LOP defect persists for 2.5 +/- 0.5 seconds. A VT LOP failure is cleared when the VT LOP defect is absent for 10 +/- 0.5 seconds.
Line Alarm Indication Signal
A Line Alarm Indication Signal (L-AIS) is defined in ANSI
T1.105. The following criteria are specific to the L-AIS
defect:
-- Line AIS defect is detected as a "111" pattern in
bits 6, 7, and 8 of the K2 byte in five consecutive
frames.
-- Line AIS defect is terminated when bits 6, 7, and 8
of the K2 byte do not contain the code "111" for five
consecutive frames.
A Line AIS failure is declared when the Line AIS defect persists for a period of 20.5 +/- 0.5 seconds. A Line AIS failure is cleared when the Line AIS defect is absent for 10 +/- 0.5 seconds.
STS-Path Alarm Indication Signal
The STS-Path Alarm Indication Signal (AIS) is defined in
ANSI T1.105 as all ones in bytes H1, H2, and H3 as well
as all ones in the entire STS SPE. The following
criteria are specific to the STS-Path AIS defect:
-- STS-Path AIS defect is detected as all ones in bytes
H1 and H2 in three contiguous frames.
-- The STS-Path AIS defect is terminated when a valid STS
Pointer is detected with the NDF set to "1001" (inverted)
for one frame, or "0110" (normal) for three contiguous
frames.
A STS-Path AIS failure is declared when the STS-Path AIS defect persists for 2.5 +/- 0.5 seconds. A STS-Path AIS failure is cleared when the STS-Path AIS defect is absent for 10 +/- 0.5 seconds.
VT-Path Alarm Indication Signal
The VT-Path Alarm Indication Signal (AIS) is only
applicable for VTs in the floating mode of operation.
VT-Path AIS is used to alert the downstream VT Path
Terminating Entity (PTE) of an upstream failure. Upon
detection of a failure, Line AIS, or STS-Path AIS, an STS
PTE will generate downstream VT-Path AIS if the STS
Synchronous Payload Envelope (SPE) is carrying floating
VTs. VT-Path AIS is specified in ANSI T1.105 as all ones
in bytes V1, V2, V3, and V4, as well as all ones in the
entire VT SPE. The following criteria are specific to
VT-Path AIS defect:
-- VT-Path AIS defect is detected by a VT PTE as all
ones in bytes V1 and V2 in three contiguous VT
superframes.
-- VT-Path AIS defect is terminated when valid VT
pointer with a valid VT size is detected with the NDF set
to "1001" (inverted) for one VT superframe, or "0110"
(normal) for three contiguous VT superframes are detected.
A VT-Path AIS failure is declared when the VT-Path AIS defect persists for 2.5 +/- 0.5 seconds. A VT-Path AIS failure is cleared when the VT-Path AIS defect is absent for 10 +/- 0.5 seconds.
Line Remote Defect Indication
Line Remote Defect Indication (RDI) (aka Line FERF)
signal is the occurrence of a "110" pattern in bit
positions 6, 7, and 8 of the K2 byte in STS-1 #1 of the
STS-N signal. Line RDI is defined in ANSI T1.105. The
following criteria are specific to Line RDI defect:
-- Line RDI defect is a "110" code in bits 6, 7, and 8
of the K2 byte of in STS-1 #1 in five consecutive frames.
-- Line RDI defect is terminated when any code other
than "110" is detected in bits 6, 7, and 8 of the K2 byte
in five consecutive frames.
A Line Remote Failure Indication (RFI) failure is declared when the incoming Line RDI defects lasts for 2.5
+/- 0.5 seconds. The Line RFI failure is cleared when no
Line RDI defects are detected for 10 +/- 0.5 seconds.
STS-Path Remote Defect Indication
STS-Path RDI (aka STS-Path FERF) signal shall be
generated within 100 milliseconds by the STS PTE upon
detection of an AIS or LOP defect. Transmission of the
STS-Path RDI signal shall cease within 100 milliseconds
when the STS PTE no longer detects STS-Path AIS or STS-
Path LOP defect. The STS-Path RDI shall accurately
report the presence or absence of STS-Path AIS or STS-
Path LOP defects. STS-Path RDI defect is defined in ANSI
T1.105. The following requirements are specific to the
STS-Path RDI defect:
-- STS-Path RDI is detected by all STS PTEs. STS-Path
RDI is detected by the upstream STS PTE as a "1" in bit
five of the Path Status byte (G1) for five contiguous
frames.
-- Removal of STS-Path Remote Defect Indication is
detected by a "0" in bit 5 of the G1 byte in five
contiguous frames.
A STS-Path Remote Failure Indication (RFI) failure is declared when the incoming STS-Path RDI defects lasts for 2.5 +/- 0.5 seconds. The STS-Path RFI failure is cleared when no STS-Path RDI defects are detected for 10 +/- 0.5 seconds.
VT-Path Remote Defect Indication
VT Path RDI (aka VT Path FERF) signal shall be generated
within 100 milliseconds by the VT PTE upon detection of a
VT-Path AIS or LOP defect. Transmission of the VT-Path
RDI signal shall cease within 100 milliseconds when the
VT PTE no longer detects VT-Path AIS or VT-Path LOP
defect. The VT-Path RDI shall accurately report the
presence or absence of VT-Path AIS or VT-Path LOP
defects. VT-Path RDI defect is defined in ANSI T1.105.
The following requirements are specific to VT-Path RDI
defect:
-- VT-Path RDI defect is the occurrence of a "1" in bit
4 of the VT-Path Overhead byte (V5) in five contiguous
frames.
-- VT-Path RDI defect is terminated when a "0" is
detected in bit 4 of the VT-Path Overhead byte (V5) for
five contiguous frames.
A VT-Path Remote Failure Indication (RFI) (derived) failure is declared when the incoming VT-Path RDI defects lasts for 2.5 +/- 0.5 seconds. The VT-Path RFI failure is cleared when no VT-Path RDI defects are detected for 10 +/- 0.5 seconds.
VT-Path Remote Failure Indication
The VT-Path RFI signal is only required for the case of
byte synch mapped DS1s where the DS1 frame bit is not
mapped. The VT-Path RFI is specified in ANSI T1.105,
where it is currently called VT path yellow. When
provided, the VT-Path RFI signal is used to indicate the
occurrence of far-end failures. When the VT-Path RFI is
not provided, far-end failures are derived from local
timing of the VT-Path RDI defect. The VT-Path RFI
failure is declared within 5 ms of detecting the incoming
VT-Path RFI Signal. The VT-Path Remote Failure
Indication (RFI) failure is cleared within 50 ms of
detecting the removal of the incoming VT-Path RFI signal.
Coding Violation
Coding Violations (CV) are Bit Interleaved Parity (BIP)
errors that are detected in the incoming signal. CV
counters are incremented for each BIP error detected.
That is, each BIP-8 can detect up to eight errors per
STS-N frame, with each error incrementing the CV counter.
Section CVs shall be collected using the BIP-8 in the B1
byte located in the Section Overhead of STS-1 #1. Line
CVs shall be collected using the BIP-8s in B2 bytes
located in the Line Overhead of each STS-1 (since all CVs
on an STS-N line are counted together, this is equivalent
to counting each error in the BIP-8*N contained in the B2
bytes of the STS-N Line Overhead). Thus, on an STS-N
signal, up to 8 x N CVs may occur in each frame. Path
CVs shall be collected using the BIP-8 in the B3 byte of
the STS-Path Overhead of the STS SPE. VT CVs shall be
collected using the BIP-2 in the V5 overhead byte of the
floating VT.
Errored Seconds
At each layer, an Errored Second (ES) is a second with
one or more Coding Violations at that layer OR one or
more incoming defects (e.g., SEF, LOS, AIS, LOP) at that
layer has occurred.
Severely Errored Seconds
At each layer, an Severely Errored Second (SES) is a
second with x or more CVs at that layer, or a second
during which at least one or more incoming defects at
that layer has occurred. Values of x vary depending on
the line rate and the Bit Error Rate. See Section 3.4
for values for x.
Severely Errored Framing Seconds
A Severely Errored Framing Second (SEFS) is a seconds
with containing one or more SEF events. This counter is
only counted at the Section Layer.
Unavailable Seconds
At the Line, Path, and VT layers, an unavailable second
is calculated by counting the number of seconds that the
interface is unavailable. At each layer, the SONET/SDH
interface is said to be unavailable at the onset of 10
contiguous SESs. The 10 SESs are included in unavailable
time. Once unavailable, the SONET/SDH interface becomes
available at the onset of 10 contiguous seconds with no
SESs. The 10 seconds with no SESs are excluded from
unavailable time. With respect to the SONET/SDH error
counts at each layer, all counters at that layer are incremented while the SONET/SDH interface is deemed available at that layer. While the interface is deemed unavailable at that layer, the only count that is incremented is UASs at that layer.
A special case exists when the 10 or more second period crosses the 900 second statistics window boundary, as the foregoing description implies that the SES and UAS counters must be adjusted when the Unavailable Signal State is entered. Clearly, successive GETs of the affected sonetPathIntervalSES and sonetPathIntervalUAS (for the Line and VT also) objects will return differing values if the first GET occurs during the first few seconds of the window. This is viewed as an unavoidable side-effect of selecting the presently defined managed objects as a basis for this memo.
Unequipped
If a Path or VT connection is not provisioned (idle) the
SONET equipment will signal this state by transmitting
the Path or VT Signal Label as follows:
- byte C2 of the STS Path Overhead equal to 0 for an
unequipped Path,
- byte V5 of the VT Path Overhead equal to 0 for an
unequipped VT.
Signal Label Mismatch
A Path or VT connection is not correctly provisioned if a
received Path or VT Signal Label mismatch occurs. A
received Signal Label is considered mismatched if it does
not equal either the locally provisioned value or the
value 'equipped non-specific' (1 hex). Note that any
received non-zero Signal Label is considered a locally
provisioned value of 'equipped non-specific'. Only in-
service, provisioned Path Terminating equipment can
detect mismatched Signal labels. It is considered
provisioned if it has been configured for a mapping and
has been assigned signals to and from which the mapping
takes place.
Circuit Identifier
This is a character string specified by the circuit
vendor, and is useful when communicating with the vendor
during the troubleshooting process.
