2 Introduction
This document describes a model for managing encapsulated SONET Time
Division Multiplexed (TDM) digital signals for transmission over a
Packet Switched Network (PSN).
This document is closely related to [CEP], 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 CEP 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 [IFMIB], a CEP connection will be a pseudo-wire
(PW), and will therefore not be represented in the ifTable.
CEP is currently specified to carry "structured" SONET paths. Meaning
that each SONET PATH/VT within the section/line/path can be processed
separately. The SONET section/line/path interface stack is modeled
within [SONETMIB]. The CEP MIB will reference SONET paths as modeled
within [SONETMIB].
Comments should be made directly to PWE3 group at pwe3@ietf.org.
This memo does not, in its draft form, specify a standard for the
Internet community.

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].
3 Terminology
CEP terminology comes from the CEP draft that describes a mechanism
for transporting SONET Time Division Multiplexed (TDM) digital
signals over a packet-oriented network. The mechanism for structured
(as outlined in the CEP draft) terminates the SONET section and line
overhead and then breaks the SONET path's Synchronous Payload
Envelope (SPE) into fragments for transmission over a PSN. Mechanism
for terminating of the SONET path overhead and extracting SONET VTs
are also described in [CEP]. Mechanisms for Fractional SONET SPE
emulation are described in [CEP]. A CEP header is appended at the
beginning of each fragment to provide information regarding where
the SPE begins within the packet stream, a sequence number, and
pointer adjustment information (see [CEP]).
"Outbound" references the traffic direction where a SONET 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 path into the SONET section and line.
Since A SONET path is bi-directional and symmetrical, it uses the
same SONET time-slot, SONET width and packet size. Inbound and
outbound PW labels may differ.
CEP will normally transmit into an originating "head" end of a PSN's
tunnel, and receive from a terminating "tail" end a PSN's tunnel. In
the case of an MPLS PSN, a CEP connection typically uses a PW Label
within a Tunnel Label [PW-SIG]. Multiple CEP PWs each with a unique
PW Label and similar traffic engineering requirements can share the
same PSN tunnel. For MPLS PSNs, the Tunnel Label is known as the
"outer" Label, while the PW Label is known as the "inner" Label. An
exception to this is with adjacent MPLS LSRs. In this case, there is
an option for CEP PWs to connect directly without an outer Label.
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
Danenberg et al Expires December 2004 3
Internet Draft PW CEP MIB June 2004
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
This MIB module is designed to satisfy the following requirements and
constraints:
- Fits within the architecture defined [PWMIB].
- The MIB module supports point-to-point CEP connections.
- The MIB module configures the connection: timeslots, packet length,
error actions, and many other CEP objects.
- The MIB module reports: packet counts, error counts, and many other
status objects.
6 CEP MIB module usage
Note: For clarity of the example below, in most cases we refer to the
PATH SONET signal configuration only. When configuring VT mode as
described in [CEP], the same apply for the VT level.
6.1 Summary of CEP MIB
- The CEP PW Table (pwVcCepTable) contains the SONET Path ifIndex,
SONET Path Time slot, the pwVcCepCfgTable index, config error
indications, and various status indications.
- The CEP PW Configuration Parameter Table (pwVcCepCfgTable) has
objects for CEP PW configuration. In situations where sets of config
objects are common amongst more than 1 CEP PW, 1 entry here may be
referenced by many pwVcCepTable entries.
- The CEP Performance Current Table (pwVcCemPerfCurrentTable)
contains CEP stats for the current 15-minute period.
- The CEP Performance Interval Table (pwVcCemPerfIntervalTable) is
similar to the pwVcCemPerfCurrentTable. 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. See [SONETMIB].
- The CEP Performance Total Table (pwVcCepPerfTotalTable) is similar
to the pwVcCemPerfCurrentTable. It contains statistics accumulated
since the CEP PW was first established.
Danenberg et al Expires December 2004 4
Internet Draft PW CEP MIB June 2004
- The CEP Fractional Table (pwVcCepFracTable) adds configuration and
monitoring parameters for fractional SPE PWs.
- The Conformance Config Table (pwVcCepConformanceCfgTable) allows
the vendor to specify the extent to which certain objects are
supported (or not).
6.2 CEP configuration Step by Step
Configuring a CEP PW involves the following steps.
First create an entry in the pwVcTable and configure the PSN tunnels:
- Follow steps as defined in [PWMIB].
Configure the SONET Path parameters:
- Set the SONET path width in the sonetPathCurrentTable [SONETMIB].
- Set the SONET path index and the SONET path starting time slot in
the pwVcCepTable.
NOTE: The agent will have created an entry in the pwVcCepTable based
on the entry created in the pwVcTable.
Configure the CEP PW:
- If necessary, create an entry in the pwVcCepCfgTable (a suitable
entry may already exist). Set packet length, etc.
- Set the index of this pwVcCepCfgTable entry in the pwVcCepTable.
Observe the CEP PW:
- Once a CEP PW is operational, the pwVcCepPerfCurrentTable,
pwVcCepPerfIntervalTable, and pwVcCepPerfTotalTable are used to
monitor the various counts, indicators, and conditions of the PW.
Conforming to the CEP MIB objects:
- The pwVcCepConformanceCfgTable 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.

Internet Draft PW CEP MIB June 2004
7 Example of CEP PW Setup
In this section we provide an example of using the MIB objects
described in section 8 to set up a CEP PW (width of 3 STSs, starting
at time slot 1). 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 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 pwVcCepCfgTable index is 9.
In [SONETMIB] sonetPathCurrentEntry (ifIndex = 23) :
{
sonetPathCurrentWidth = 3,
sonetPathCurrentStatus
...
...
}
Create an entry in the pwVcCepCfgTable (index = 9) :
{
pwVcCepCfgSonetPaylaodLength = 783 -- payload bytes
pwVcCepCfgMinPktLength = 0 -- no minimum
pwVcCepCfgPktReorder = FALSE
pwVcCepCfgEnableDBA = ais
pwVcCepCfgRtpHdrSuppress = FALSE
pwVcCepCfgJtrBfrDepth = 500 -- micro-seconds
pwVcCepCfgConsecPktsInsync = 2 -- Exit LOPS state
pwVcCepCfgConsecMissingOutSync = 10 -- Enter LOPS state
pwVcCepCfgPktErrorPlayOutValue = playAllOnes
pwVcCepCfgMissingPktsToSes = 3 -- packets,
pwVcCepCfgSesToUas = 2 -- seconds,
pwVcCepCfgSecsToExitUas = 10 -- seconds,
pwVcCepCfgRowStatus = createAndGo
}
Check that there are no error bits set in pwVcCepConfigError.
Danenberg et al Expires December 2004 6
Internet Draft PW CEP MIB June 2004
In PW MIB: Get a new index and create a new pwVcTable entry using
pwVcIndexNext (here, the PW index = 83) and pwVcRowStatus. In this
new entry, set pwVcType to 'cep'. This should create a new entry in
the pwVcCepTable. Set up and the SONET path ifIndex, SONET path time
slot, and Cfg Table indexes within this new pwVcCep table entry:
{
pwVcCepSonetIfIndex = 23 -- Index of associated entry
-- in sonetPathCurrent table.
pwVcCepSonetTimeSlot = 1 -- Starting time slot.
pwVcCepCfgIndex = 9 -- Index of associated entry
-- in pwVcCepCfg table (above).
}
Check that there are no error bits set in pwVcCepSonetConfigError.

DESCRIPTION
"The number of previous 15-minute intervals for which data

An agent with CEP capability must be capable of supporting
at least n intervals. The minimum value of n is 4, The
default of n is 32 and the maximum value of n is 96.
The value will be <n> unless the measurement was (re-)
started within the last (<n>*15) minutes, in which case the
value will be the number of complete 15 minute intervals for
which the agent has at least some data. In certain cases
(e.g., in the case where the agent is a proxy) it is
possible that some intervals are unavailable. In this case,
this interval is the maximum interval number for which data
is available. "

DESCRIPTION
"Definitions:
missingPkt - While playing out a sequence of packets, a
packet(s) was determined to be missing based on a gap in the
CEP sequence number. Note: If the implementation supports
packet re-ordering, detecting gaps should not take place as
packets arrive, only as they are played out - this gives
time for mis-ordered packets to arrive late.
ooRngDropped - Packet(s) arrives that is outside the
range of the jitter buffer. This may be because the
jitter buffer is full, or the sequence number addresses
a buffer outside the current jitter buffer range, or
addresses an already occupied buffer within range.
Whether or not packet re-ordering is supported by the
implementation, this indication MUST be supported.
jtrBfrUnder - The jitter buffer underflowed due to
not enough packets arriving as packets were being

played out.
pktBadLength - Non-bandwidth-saving packet arrives
larger or smaller than pwVcCepCfgSonetPayloadLength, or when
a fractional SPE packet length does not match the extension
header or manual configuration indicating the number of
equipped VTs.
lops - Loss Of Packet Sync. See draft-ietf-pwe3-sonet.
cepRdi - Circuit Emulation over Packet Remote Defect
Indication. Generated by the remote CEP de-packetizer when
detecting LOPS. Note: not generated by the remote SONET
function. See draft-ietf-pwe3-sonet.
cepAis - Remote CEP packetizer has detected AIS
on its incoming SONET stream. See draft-ietf-pwe3-
sonet. Note: cepAis MUST NOT (in itself) cause a CEP
down notification. This would be a layer violation.
badHdrStack - This indication is set when the number of
CEP header extensions detected in incoming packets does
not match the expected number.
Note: currently there is no hierarchy of CEP defects.
Note: the algorithm used to capture these indications
is implementation specific."

DESCRIPTION
"The number of SONET bytes of the Path or VT carried as

circuits, value of 783 bytes indicates that each packet
carries payload equivalent to one frame. For VT1.5 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
pwVcCepPerf...PktsBadLength.) "

Similarly, 'unequipped' MUST cause payload suppression
when an un-equipped condition is detected on the SONET

to be sent, but with indicators set in the CEP header
instructing the remote to play all ones (for AIS) or all
zeros (for un-equipped) onto its SONET path.
NOTE: Some implementations may not support this feature.
In these cases, if the 'ais' or 'unequipped' bits are set,
then 'dba' error code MUST be set in pwVcCepConfigError."

9 Security considerations
It is clear that this MIB module is potentially useful for
monitoring of 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 a 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 pwVcCepTable, pwVcCepCfgTable and pwVcCepFracTable 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.
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 pwVcCepTable, pwVcCepPerfCurrentTable,
pwVcCepPerfIntervalTable and pwVcCepPerfTotalTable collectively
show the CEP pseudo wire connectivity topology and its
performance characteristics.
If an Administrator does not want to reveal this information,
then these tables should be considered sensitive/vulnerable.
Danenberg et al Expires December 2004 53
Internet Draft PW CEP MIB June 2004
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.
10 IANA considerations
As requested in the PW TC MIB [PWTCMIB], PWE3 related standards
track MIB modules should be rooted under the pwStdMIB subtree. The
IANA is requested to assign { pwStdMIB 4 } to the PW CEP MIB module
specified in this document.
