Expires July 12, 2008 [Page 2] Internet-Draft PW CEP MIB January 2008 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 July 12, 2008 [Page 3] Internet-Draft PW CEP MIB January 2008 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. 3.

Malis - Tellabs Dave Danenberg - Litchfield Communications Scott C. Park - Litchfield Communications 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 July 12, 2008 [Page 4] Internet-Draft PW CEP MIB January 2008 - 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 July 12, 2008 [Page 5] Internet-Draft PW CEP MIB January 2008 - 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 July 12, 2008 [Page 6] Internet-Draft PW CEP MIB January 2008 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 July 12, 2008 [Page 7] Internet-Draft PW CEP MIB January 2008 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: Zelig, et al.

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.

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 July 12, 2008 [Page 67] Internet-Draft PW CEP MIB January 2008 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 { mib-2 XXXX } Editor's Note (to be removed prior to publication): The IANA is requested to assign a value for "XXXX" under the 'mib-2' subtree and to record the assignment in the SMI Numbers registry. When the assignment has been made, the RFC Editor is asked to replace "XXXX" Zelig, et al. Expires July 12, 2008 [Page 68] Internet-Draft PW CEP MIB January 2008 (here and in the MIB module) with the assigned value and to remove this note. 10. References 10.1.
