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). This document is also related to [TRANS and ENCAP], describing the transport and encapsulation of Layer 2 circuits over MPLS, respectively. NOTE: the CEP encapsulation can be used over non-MPLS PSNs as well as MPLS PSNs. The model for CEP management is a MIB. The CEP MIB described in this document works closely with the MIBs described in [PWMIB] and the textual conventions defined in [PWTC]. In the spirit of the [IFMIB], a CEP connection will be a virtual connection (VC), and will therefore not be represented in the ifTable. CEP is currently specified to carry SONET paths as a "structured" adaptation meaning that each SONET path within the section/line is processed separately. The SONET section/line interface stack is modeled within [SONETMIB]. The CEP MIB will reference SONET paths as modeled within [SONETMIB]. Comments should be made directly to PWE3 at pwe3@ietf.org. This memo does not, in its draft form, specify a standard for the Internet community. Conventions used in this document Danenberg et al Expires January 2002 2 Internet Draft PW CEM MIB November 2001 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. 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]). "Adaptation" refers to the method of adapting a "foreign" communications protocol such that it can be carried by a "native" protocol. In this case, the foreign protocol is SONET/SDH and the native protocol is packet (e.g., MPLS). "Outbound" references the traffic direction where a SONET path's payload (SPE) is received, adapted to packet, assigned a VC 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, packet size. Inbound and outbound VC 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 VC (virtual connection) Label within a Tunnel Label [TRANS]. Multiple CEP VCs each with a unique VC 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 VC 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 VCs to connect directly without an outer Label. 4 The SNMP Management Framework The SNMP Management Framework presently consists of five major components: o An overall architecture, described in RFC 2571 [RFC2571]. Danenberg et al Expires January 2002 3 Internet Draft PW CEM MIB November 2001 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. 4.1 Object Definitions 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) defined in the SMI. In particular, each object type is named by an OBJECT IDENTIFIER, an administratively assigned name. 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 descriptor, to also refer to the object type. Danenberg et al Expires January 2002 4 Internet Draft PW CEM MIB November 2001 5 Feature Checklist This MIB is designed to satisfy the following requirements and constraints: - Fit within the architecture defined [PWMIB]. - The MIB supports point-to-point CEP connections. Point-to- multipoint connections are for future study. - The MIB configures the connection: timeslots, packet length, error actions, and many other CEP objects. - The MIB reports: packet counts, error counts, and many other status objects. 6 CEP MIB usage 6.1 Summary of CEP MIB - The CEP SONET extension table (pwVcCepSonetExtTable) is used to indicate the time slot of the SONET path to be adapted . This table also contains the index to the pwVc and pwVcCep tables (for reverse mapping). - The CEP VC Configuration Parameter Table (pwVcCepCfgTable) has entries of CEP VC configuration objects. In situations where config params are common amongst CEP VCs, 1 entry here may be referenced by many mplsCepVcTable entries. - The CEP VC Table (pwVcCepTable) contains the SONET Path ifIndex and the pwVcCepCfgTable index. - 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]. 6.2 CEP configuration Step by Step Configuring a CEP VC involves the following steps. First create an entry in the pwVcTable and configure the PSN tunnels: - Follow steps as defined in [PWMIB]. Danenberg et al Expires January 2002 5 Internet Draft PW CEM MIB November 2001 Configure the SONET Path parameters : - Set the SONET path width in the sonetPathCurrentTable [SONETMIB]. - Set the SONET path starting time slot in the pwVcCemSonetExtTable. Configure the CEP VC: - The agent will have created an entry in the pwVcCepTable based on the entry created in the pwVcTable. - Create an entry in the pwVcCepCfgTable set packet length, etc. - Set the index of this pwVcCepCfgTable entry in the pwVcCepTable. Observe the CEP VC: - Once a CEP VC is operational, the pwVcCepPerfCurrentTable, and pwVcCepPerfIntervalTable are used to monitor the various counts, indicators, and conditions of the VC. 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. 7 Example of CEP Setup In this section we provide an example of using the MIB objects described in section 8 to set up a CEP VC (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 VC. In this case, an STS-3c starts at SONET time slot 1 (and is evenly distributed within the SONET frame). In the following example, the ifIndex for both the sonetPathCurrentEntry and mplsCemSonetExtTable is 23, while the pwVcConfTable index is 9. Danenberg et al Expires January 2002 6 Internet Draft PW CEM MIB November 2001 In sonetPathCurrentEntry (ifIndex = 23) : { sonetPathCurrentWidth = 3, sonetPathCurrentStatus ... ... } Create an entry in the pwVcCepCfgTable (index = 9) : { pwVcCepCfgNormalPktLength = 500 -- payload bytes pwVcCepCfgMinPktLength = 0 -- no minimum pwVcCepCfgEnableDBA = allOnesOnAis pwVcCepCfgJtrBfrDepth = 50 -- packets pwVcCepCfgConsecPktsInsync = 2 -- Exit LOPS state pwVcCepCfgConsecMissingOutSync = 10 -- Enter LOPS state pwVcCepCfgPktErrorPlayOutValue = playAllOnes pwVcCepCfgMissingPktsToSes = 3 -- packets, pwVcCepCfgSesToUas = 2 -- seconds, pwVcCepCfgSesToUas = 10 -- seconds, pwVcCepCfgSecsToExitUas = 10 -- seconds, pwVcCepCfgRowStatus = createAndGo } Check that there are no error bits set in pwVcCepConfigError. In PW-MIB: Get a new index and create a new pwVcTable entry using pwVcIndexNext (here, the VC 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 and CfgTable indexes within this new pwVcCep table entry: { pwVcCepSonetIfIndex = 23 -- Index of associated entry -- in sonetPathCurrent table. pwVcCepCfgIndex = 9 -- Index of associated entry -- in pwVcCemConf table (above). } Set the VC index and the starting time-slot of the SONET path in the SONET extension table (pwVcCemSonetExtTable): { pwVcCemSonetExtVcIndex = 83 pwVcCemSonetExtPathTimeSlot = 1 } Check that there are no error bits set in pwVcCepSonetExtConfigError.
