2. Abstract
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) interfaces. This document is a
companion to the documents that define Managed Objects for the
DS1/E1/DS2/E2 and DS3/E3 Interface Types [RFC2496][RFC2495].
Textual Conventions used in this MIB are defined in [RFC2579]
and [RFC2493].
This memo replaces RFC2558 [RFC2558]. Changes relative to
RFC2558 are summarized in the MIB module's REVISION clause.
3. The SNMP Management Framework
The SNMP Management Framework presently consists of five major
components:
o An overall architecture, described in RFC 2571 [RFC2571].
o 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].
o 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].
o 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 (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.
4. Overview
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
[T1.105a][T1.105b][T1.106] and CCITT G.707, 708, 709, and
G.783 [G.707][G.708][G.709][G.783].
4.1. Use of the ifTable
This section specifies how the MIB II interfaces group, as
defined in [RFC2863], 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 terminates all SONET/SDH layers.
For example, a 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 [RFC1213], as extended by [RFC2863], 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 [RFC2863], as
follows:
_____________________________
| | | | >
| | | | |
| VT 1 |..........|VT K| > K ifEntries
| | | | |
|_____________|__________|____| >
| | | | >
| | | | |

Use of ifTable for a SONET/SDH port
The exact configuration and multiplexing of the layers is
maintained in the ifStackTable [RFC2863] and in the
ifInvStackTable [RFC2864].

4.5. SONET/SDH Terminology
The terminology used in this document to describe error
conditions on a SONET circuit as monitored by a SONET system
are from the T1.231 [T1M1.3][T1.231a][T1.231b]. 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 [G.783]. 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 [G.783]. If the
definition in this document does not match the definition in
the T1.231 document, the implementer should follow the
definition described in this document. In some cases other or
additional references are used as compared with the ones cited
above. This will be indicated in the text.
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 word 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.
A 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.
A 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
A 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.
An 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 2.5 +/- 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.
An STS-Path AIS failure is declared when the STS-Path AIS
defect persists for 2.5 +/- 0.5 seconds. An 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 x consecutive frames,
where x = 5 [T1.231a][T1.231b] or 10 [T1.231b].
-- Line RDI defect is terminated when any code other
than "110" is detected in bits 6, 7, and 8 of the K2 byte
in x consecutive frames, where x = 5 [T1.231a][T1.231b]
or 10 [T1.231b].
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 x consecutive
frames, where x = 5 [T1.231a] or 10 [T1.231b].
-- Removal of STS-Path Remote Defect Indication is
detected by a "0" in bit 5 of the G1 byte in x
consecutive frames, where x = 5 [T1.231a] or 10
[T1.231b].
An 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 x consecutive
frames, where x = 5 [T1.231a] or 10 [T1.231b].
-- VT-Path RDI defect is terminated when a "0" is
detected in bit 4 of the VT-Path Overhead byte (V5) for x
consecutive frames, where x = 5 [T1.231a] or 10
[T1.231b].
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
According to [T1M1.3][T1.231a][TR253][GR253][T1.231b] 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. The values of x in RFC1595[RFC1595] were
based on [T1M1.3] and [TR253] (see Appendix B). These
values have subsequently been relaxed in
[T1.231a][GR253][T1.231b]. In addition, according to
G.826 [G.826] SESs are measured as a percentage of
errored blocks.
To deal with these sets of definitions this memo defines
an object sonetSESthresholdSet that determines the
correct interpretation of SES. For backward
compatibility, if this object is not implemented the
interpretation of Appendix B shall apply. Otherwise, a
more recent interpretation is suggested. An agent is not
required to support all sets of definitions.
Note that CV counts should be frozen during SESs.
Note that if a manager changes the value of this object
all SES statistics collected prior to this change shall
be invalidated.
Severely Errored Framing Seconds
A Severely Errored Framing Second (SEFS) is a second
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.
Note that this definition implies that the agent cannot
determine until after a ten second interval has passed
whether a given one-second interval belongs to available
or unavailable time. If the agent chooses to update the
various performance statistics in real time then it must
be prepared to retroactively reduce the ES, SES, and SEFS
counts by 10 and increase the UAS count by 10 when it
determines that available time has been entered. It must
also be prepared to reduce the CV count by the number of
violations counted since the onset of unavailable time.
The agent must be similarly prepared to retroactively
decrease the UAS count by 10 and increase the ES and CV
counts as necessary upon entering available time. A
special case exists when the 10 second period leading to
available or unavailable time crosses a 900 second
statistics window boundary, as the foregoing description
implies that the CV, ES, SES, SEFS, and UAS counts the
PREVIOUS interval must be adjusted. In this case
successive GETs of the affected sonetPathIntervalSES and
sonetPathIntervalUAS objects (and the analogous Line and
VT objects also) objects will return differing values if
the first GET occurs during the first few seconds of the
window.
According to ANSI T1.231 unavailable time begins at the
_onset_ of 10 contiguous severely errored seconds -- that
is, unavailable time starts with the _first_ of the 10
contiguous SESs. Also, while an interface is deemed
unavailable all counters for that interface are frozen
except for the UAS count. It follows that an
implementation which strictly complies with this standard
must _not_ increment any counters other than the UAS
count -- even temporarily -- as a result of anything that
happens during those 10 seconds. Since changes in the
signal state lag the data to which they apply by 10
seconds, an ANSI-compliant implementation must pass the
one-second statistics through a 10-second delay line
prior to updating any counters. That can be done by
performing the following steps at the end of each one
second interval.
i) Read near/far end CV counter and alarm status flags from
the hardware.
ii) Accumulate the CV counts for the preceding second and
compare them to the ES and SES threshold for the layer in
question. Update the signal state and shift the one-
second CV counts and ES/SES flags into the 10-element
delay line. Note that far-end one-second statistics are
to be flagged as "absent" during any second in which
there is an incoming defect at the layer in question or
at any lower layer.
iii) Update the current interval statistics using the signal
state from the _previous_ update cycle and the one-second
CV counts and ES/SES flags shifted out of the 10-element
delay line.
This approach is further described in Appendix A. An
agent may choose to use this approach in lieu of
retroactive adjustments to the counters.
In any case, a linkDown trap shall be sent only after the
agent has determined for certain that the unavailable
state has been entered, but the time on the trap will be
that of the first UAS (i.e., 10 seconds earlier). A
linkUp trap shall be handled similarly.
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. While a Path is unequipped or has
mismatched signal labels ES/SES counts continue, but
these conditions do not themselves contribute to ES/SES.
Circuit Identifier
This is a character string specified by the circuit
vendor, and is useful when communicating with the vendor
during the troubleshooting process.

"
REVISION "9810190000Z"
DESCRIPTION
"The RFC2558 version of this memo.
The key changes made to this MIB module
since its initial publication in RFC 1595
are as follows.
(1) The MODULE-IDENTITY has been updated to reflect the
changes to the MIB.
(2) Where applicable, the textual conventions
PerfCurrentCount and PerfIntervalCount from
PerfHist-TC-MIB have been used in place of Gauge32.
(3) An agent now has the option to delay updates to
the various performance counts in lieu of performing
retroactive adjustments upon entering into or exiting
from unavailable time. This implementation option is
described in Appendix A of this memo.
(4) In order to make the SONET-MIB more useful for
circuit provisioning, the formerly read-only objects
sonetMediumType, sonetMediumLineCoding,
sonetMediumLineType, and sonetMediumCircuitIdentifier
have been given a MAX-ACCESS of read-write. The
MIN-ACCESS remains read-only.
(5) The DESCRIPTION clause for sonetMediumTimeElapsed has
been updated to describe its behaviour if the duration
of the current interval exceeds the maximum value.
(6) The DESCRIPTION clause for sonetMediumValidIntervals
has been updated to describe its behaviour when some
intervals may be unavailable, and the object
sonetMediumInvalidIntervals has been added to keep
count of the number of missing intervals (if any).
(7) The object sonetMediumLoopbackConfig has been added
to enable or disable loopback configurations.
(8) Because the error count thresholds for declaring
severely errored seconds that are specified in ANSI
T1.231-1993, ITU-T G.826-1995, and ANSI T1.231-1997
are all different from each other and from the thresholds
specified in RFC 1595, an enumerated INTEGER object
sonetSESthresholdSet has been added to allow an agent
to specify which threshold set is in use. Text has
been added to Section 4 stating that if this object is
not implemented the thresholds specified in RFC 1595
should be assumed, and the table containing those
thresholds has been moved to Appendix B of this memo.
(9) A column with SYNTAX TruthValue has been added to each
interval table. The purpose of the additional column
is to indicate, for each interval, whether the data
is valid in the sense intended by ANSI T1.231 clause
9.1.2.2 [T1.231a][T1.231b]. The objects in question are:
sonetSectionIntervalValidData
sonetLineIntervalValidData
sonetFarEndLineIntervalValidData
sonetPathIntervalValidData
sonetFarEndPathIntervalValidData
sonetVTIntervalValidData
sonetFarEndVTIntervalValidData
(10) The ranges for sonetPathCurrentStatus and
sonetVTCurrentStatus have been made consistent
with the DESCRIPTION clauses.
(11) The conformance information has been updated. Previous
conformance information from RFC 1595 has been
deprecated. Some typographical errors in the deprecated
section have been corrected in order to prevent
MIB compilation errors."

valuable contributions to this memo.
7. 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.
SNMPv1 by itself is not a secure environment. 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) 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.

Appendix A: The delay-line approach to statistics collection.
According to ANSI T1.231 unavailable time begins at the onset
of 10 contiguous severely errored seconds -- that is,
unavailable time starts with the first of the 10 contiguous
SESs -- and while an interface is deemed unavailable all
counters for that interface are frozen except for the UAS
count. Since changes in the signal state lag the data to
which they apply by 10 seconds, an implementation which wishes
to avoid making retroactive adjustments to the counts must
pass the the one-second statistics through a 10-second delay
line prior to updating any counters. That can be done by
performing the following steps at the end of each one second
interval.
i) Read near/far end line and path CV counts and alarm
status flags from the hardware.
ii) Accumulate the CV counts for the preceding second and
compare them to the ES and SES threshold for the layer in
question. Update the signal state and shift the one-
second CV counts and ES/SES flags into the 10-element
delay line. Note that far-end one-second statistics are
to be flagged as "absent" during any second in which
there is an incoming defect at the layer in question or
at any lower layer.
iii) Update the current interval statistics using the signal
state from the previous update cycle and the one-second
CV counts and ES/SES flags shifted out of the 10-element
delay line.
This procedure guarantees that the statistical counters will
be correctly updated at all times, although they lag real time
by 10 seconds. It is illustrated in the figure below. At the
end of each 15 minutes interval the current interval counts
are transferred to the most recent interval entry and each
interval is shifted up by one position, with the oldest being
discarded if necessary in order to make room. The current
interval counts then start over from zero. Note, however,
that the signal state calculation does not start anew at each
interval boundary; rather, signal state information is
retained across interval boundaries.

Note that if such a procedure is adopted there is no current
interval data for the first ten seconds after a system comes
up. noSuchInstance must be returned if a management station
attempts to access the current interval counters during this
time.
It is an implementation-specific matter whether an agent I-D Tag: draft-ietf-atommib-rfc2558bis-01.txt
assumes that the initial state of the interface is available
or unavailable.
