Internet-Draft PW CEP MIB November 2007
1. Introduction
This document describes a model for managing encapsulated SONET/SDH
Time Division Multiplexed (TDM) digital signals for transmission over
a Packet Switched Network (PSN).
This document is closely related to [RFC4842], which describes the
technology to encapsulate TDM signals and provide the Circuit
Emulation Service over a Packet Switched Network (PSN).
The model for CEP management is a MIB module. The PW-CEP-STD-MIB
module described in this document works closely with the MIB modules
described in [PWMIB] and the textual conventions defined in [PWTC].
In the spirit of the [RFC2863], a CEP connection will be a pseudowire
(PW), and will therefore not be represented in the ifTable.
CEP is currently specified to carry "structured" SONET/SDH paths,
meaning that each SONET/SDH PATH/VT within the section/line/path can
be processed separately. The SONET/SDH section/line/path interface
stack is modeled within [RFC3592].
This document adopts the definitions, acronyms and mechanisms
described in [RFC3985]. Unless otherwise stated, the mechanisms of
[RFC3985] apply and will not be re-described here.
Comments should be made directly to the PWE3 mailing list at
pwe3@ietf.org.
Conventions used in this document
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 [BCP14].
2. Terminology
CEP terminology comes from [RFC4842] that describes a mechanism for
transporting SONET/SDH Time Division Multiplexed (TDM) digital
signals over a packet-oriented network. The mechanism for structured
emulation (as outlined in the CEP draft) terminates the SONET/SDH
section and line overhead and then breaks the SONET/SDH path's
Synchronous Payload Envelope (SPE) into fragments for transmission
over a PSN. Mechanism for terminating of the SONET/SDH path overhead
and extracting SONET VTs are also described in [RFC4842]. Mechanisms
for Fractional SONET/SDH SPE emulation are described in [RFC4842]. A
CEP header is appended at the beginning of each fragment to provide
information regarding where the SPE begins within the packet stream,
Zelig, et al. Expires May 21, 2008 [Page 3]
Internet-Draft PW CEP MIB November 2007
a sequence number and pointer adjustment information (see [RFC4842]).
"Outbound" references the traffic direction where a SONET/SDH path's
payload (SPE) is received, adapted to packet, assigned a PW label and
sent into the PSN.
Conversely, "inbound" is the direction where packets are received
from the PSN, packet payloads are reassembled back into an SPE and
inserted as a SONET/SDH path into the SONET/SDH section and line.
Since A SONET/SDH path is bi-directional and symmetrical, CEP uses
the same SONET/SDH time-slot, SONET/SDH width and packet size.
Inbound and outbound PW labels may differ.

4. 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].
5. Feature Checklist
The PW-CEP-STD-MIB module is designed to satisfy the following
requirements and constraints:
Zelig, et al. Expires May 21, 2008 [Page 4]
Internet-Draft PW CEP MIB November 2007
- The MIB module is designed to be work with the PW-STD-MIB [PWMIB]
module.
- The MIB module is independent of the PSN type.
- The MIB module supports all the signal types as defined in
[RFC4842]: SPE, fractional SPE, VT, both SONET and SDH mapping and
all the optional features as defined in [RFC4842].
- The MIB module reports all the statistics as defined by [RFC4842].
6. MIB Module Description and Usage
For clarity of the description below, in most cases we refer to the
SONET PATH signal configuration only, but the same examples are
applicable for SDH signals and VT level processing as well, as
described in [RFC3985].
6.1. PW-CEP-STD-MIB Summary
- The CEP PW Table (pwCepTable) contains the SONET/SDH Path/VT
ifIndex, SONET/SDH Path Time slot, the pwCepCfgTable index, config
error indications and various status indications.
- The CEP PW Configuration Parameter Table (pwCepCfgTable) has
objects for CEP PW configuration. In situations where sets of
config objects are common amongst more than one CEP PW, a single
entry here may be referenced by many pwCepTable entries.
- The CEP Performance Current Table (pwCemPerfCurrentTable) contains
CEP stats for the current 15-minute period.
- The CEP Performance 15 Minute Interval Table
(pwCemPerfIntervalTable) is similar to the pwCemPerfCurrentTable.
It contains historical intervals (usually 96 15-minute entries to
cover a 24 hour period).
Note: the performance interval statistics are supported by CEP due
to the very function of CEP - that is, processing SONET/SDH. See
[RFC3592].
- The CEP Performance 1 day Table (pwCepPerf1DayTable) contains
statistics accumulated during the current day and contains
previous days historical statistics.
Zelig, et al. Expires May 21, 2008 [Page 5]
Internet-Draft PW CEP MIB November 2007
- The CEP Fractional Table (pwCepFracTable) adds configuration and
monitoring parameters for fractional SPE PWs.
- The Conformance Config Table (pwCepConformanceCfgTable) allows the
vendor to specify the extent to which certain objects are
supported (or not).
6.2. MIB modules required for IMPORTS
The PW-CEP-STD-MIB IMPORTS objects from SNMPv2-SMI [RFC2578],
SNMPv2-TC [RFC2579], SNMPv2-CONF [RFC2580], SNMP-FRAMEWORK-MIB
[RFC3411], PerfHist-TC-MIB [RFC3593], HC-PerfHist-TC-MIB [RFC3705],
IF-MIB [RFC2863], PW-STD-MIB [PWMIB] and PW-TC-STD-MIB [PWTC].
6.3. PW-STD-MIB Modules Usage
The MIB module structure for defining a PW service is composed of
three layers of MIB modules functioning together. This general model
is defined in the PWE3 architecture [RFC3985]. The layering model is
intended to sufficiently isolate PW services from the underlying PSN
layer that carries the emulated service. This is done at the same
time as providing a standard means for connecting any supported
services to any supported PSNs.
The first layer, known as the service layer, contains service-
specific modules such as the one defined in this document. These
modules define service-specific management objects that interface or
collaborate with existing MIB modules for the native version of the
service. The service-specific module "glues" the standard modules to
the PWE3 MIB modules. The PW-CEP-STD-MIB module defined in this memo
serves as one of the PW type-specific MIB module.
The next layer of the PWE3 MIB framework is the PW-STD-MIB module
[PWMIB]. This module is used to configure general parameters of PWs
that are common to all types of emulated services and PSNs. This
layer is connected to the service-specific layer above and the PSN
layer below.
The PSN layer provides PSN-specific modules for each type of PSN.
These modules associate the PW with one or more "tunnels" that carry
the service over the PSN. These modules are defined in other
documents. This module is used to "glue" the PW service to the
underlying PSN-specific MIB modules.
Zelig, et al. Expires May 21, 2008 [Page 6]
Internet-Draft PW CEP MIB November 2007
6.4. PW-CEP-STD-MIB Module Usage
Configuring a CEP PW involves the following steps.
First create an entry in the pwTable:
- Follow steps as defined in [PWMIB].
Configure the PSN tunnel in the respective PSN specific PWE3 PSN glue
MIB module and the respective PSN specific MIB modules. Configure
the SONET Path parameters:
- Set the SONET path width in the sonetPathCurrentTable [RFC3592].
- Set the SONET path index and the SONET path starting time slot in
the pwCepTable.
NOTE: The agent had created an entry in the pwCepTable based on the
entry created in the pwTable.
Configure the CEP PW:
- If necessary, create an entry in the pwCepCfgTable (a suitable
entry may already exist). Set packet length, etc.
- Set the index of this pwCepCfgTable entry in the pwCepTable.
Observe the CEP PW:
- Once a CEP PW is operational, the pwCepPerfCurrentTable,
pwCepPerfIntervalTable and pwCepPerf1DayTable can be used to
monitor the various counts, indicators and conditions of the PW.
Conforming to the PW-CEP-STD-MIB objects:
- The pwCepConformanceCfgTable is used to state True/False whether
certain objects are supported. An ASCII string object is
available with every True/False object as a means to explain the
extent of 'true' support, or perhaps explain why the 'false' was
set.
6.5. Example of PW-CEP-STD-MIB Usage
In this section we provide an example of using the MIB objects
described in Section 7 to set up a CEP PW. While this example is not
meant to illustrate every permutation of the MIB, it is intended as
an aid to understanding some of the key concepts. It is meant to be
read after going through the MIB itself. See [PWMIB] for an example
Zelig, et al. Expires May 21, 2008 [Page 7]
Internet-Draft PW CEP MIB November 2007
of setting up PSN Tunnels.
First configure the SONET path width, starting time-slot and
associated CEP PW. In this case, an STS-3c starts at SONET time slot
1 (and is distributed normally within the SONET frame). In the
following example, the ifIndex for the sonetPathCurrentEntry is 23,
while the pwCepCfgTable index is 9.
In [RFC3592] sonetPathCurrentEntry (ifIndex = 23) :
{
sonetPathCurrentWidth = 3,
sonetPathCurrentStatus
...
...
}
Create an entry in the pwCepCfgTable (index = 9) :
{
pwCepCfgSonetPaylaodLength = 783 -- payload bytes
pwCepCfgMinPktLength = 0 -- no minimum
pwCepCfgPktReorder = true
pwCepCfgEnableDBA = unequipped
pwCepCfgRtpHdrSuppress = false
pwCepCfgJtrBfrDepth = 500 -- micro-seconds
pwCepCfgConsecPktsInsync = 2 -- Exit LOPS state
pwCepCfgConsecMissingOutSync = 10 -- Enter LOPS state
pwCepCfgPktErrorPlayOutValue = 0xFF -- All ones
pwCepCfgMissingPktsToSes = 3 -- packets,
pwCepCfgSesToUas = 2 -- seconds,
pwCepCfgSecsToExitUas = 10 -- seconds,
pwCepCfgRowStatus = createAndGo
}
Verify that there is no error bit set in pwCepConfigError.
In the PW-STD-MIB module: Get a new index and create a new pwTable
entry using pwIndexNext (here, the PW index = 83) and pwRowStatus.
In this new entry, set pwType to 'cep'. The agent will create a new
entry in the pwCepTable. Set the SONET path ifIndex, SONET path time
slot and Cfg Table indexes within this new pwCep table entry:

DESCRIPTION
"The number of SONET bytes of the Path or VT carried as
payload within one packet. For example, for STS-1/VC-3 SPE
circuits, value of 783 bytes indicates that each packet
carries payload equivalent to one frame. For VT1.5/VC11
circuits, a payload length of 104 bytes indicates that each
packet carries payload equivalent to one VT1.5 super-frame.
The actual payload size may be different, due to bandwidth
reduction modes, e.g. DBA mode or dynamically assigned
fractional SPE. This length applies to
inbound and outbound packets carrying user payload.
Although there is no control over inbound packets, those
of illegal length are discarded and accounted for (see
pwCepPerf...Malformed.)
The default values are determined by the pwCepType:
783 for pwCepType equal spe(2) or fracSpe(3).
For vt(3) modes, the applicable super-frame payload size
is the default value.

8. Security Considerations
It is clear that this MIB module is potentially useful for monitoring
CEP PWs. This MIB can also be used for configuration of certain
objects and anything that can be configured can be incorrectly
configured, with potentially disastrous results.
There are 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:
o the pwCepTable, pwCepCfgTable and pwCepFracTable contains objects
to CEP PW parameters on a Provider Edge (PE) device. Unauthorized
access to objects in these tables could result in disruption of
traffic on the network. The use of stronger mechanisms such as
SNMPv3 security should be considered where possible.
Specifically, SNMPv3 VACM and USM MUST be used with any v3 agent
which implements this MIB module. Administrators should consider
whether read access to these objects should be allowed, since read
access may be undesirable under certain circumstances.
Zelig, et al. Expires May 21, 2008 [Page 67]
Internet-Draft PW CEP MIB November 2007
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. These are the tables and objects and their
sensitivity/vulnerability:
o the pwCepTable, pwCepPerfCurrentTable, pwCepPerfIntervalTable and
pwCepPerf1DayTable collectively show the CEP pseudowire
connectivity topology and its performance characteristics. If an
Administrator does not want to reveal this information, then these
tables should be considered sensitive/vulnerable.
SNMP versions prior to SNMPv3 did not include adequate security.
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 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.
9. IANA Considerations
The MIB module in this document uses the following IANA-assigned
OBJECT IDENTIFIER values recorded in the SMI Numbers registry:
Descriptor OBJECT IDENTIFIER value
---------- -----------------------
pwCepStdMIB { transmission XXXX }
Editor's Note (to be removed prior to publication): The IANA is
requested to assign a value for "XXXX" under the 'transmission'
subtree and to record the assignment in the SMI Numbers registry.
When the assignment has been made, the RFC Editor is asked to replace
Zelig, et al. Expires May 21, 2008 [Page 68]
Internet-Draft PW CEP MIB November 2007
"XXXX" (here and in the MIB module) with the assigned value and to
remove this note.
