Introduction This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it defines a MIB module that can be used to manage pseudowire (PW) services for transmission over a packet Switched Network (PSN) [RFC3931] [RFC4447]. This MIB module provides generic management of PWs which is common to all types of PSN and PW services defined by the IETF PWE3 Working Group. Comments should be made directly to the PWE3 mailing list at pwe3@ietf.org. 2. 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]. 3. Conventions 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]. This document adopts the definitions, acronyms and mechanisms described in [RFC3985] and [RFC3916]. Unless otherwise stated, the mechanisms of [RFC3985] apply and will not be re-described here. 4. Co-Authors The individuals listed below are co-authors of this document. Dave Danenberg - Litchfield Communications Nadeau & Zelig Expires July 12, 2008 [Page 3] Internet-Draft PW MIB January 2008 Sharon Mantin - Corrigent Systems 5. Overview The PWE3 MIB Modules architecture provides a layered modular model into which any supported emulated service can be connected to any supported PSN type. This specific MIB module provides the glue for mapping between the emulated service onto the native PSN service. As such the defining of a PW emulated service requires the use of at least three types of MIB modules. Starting from the emulated service, the first type is service- specific module, which is emulated signal type dependent. These modules are defined in other documents. The second type is this module, the PW-STD-MIB module, which configures general parameters of the PW that are common to all types of emulated services and PSN types. The third type of modules is PSN-specific module. There is a different module 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. 6. Structure of the MIB Module The MIB Module consists of five tables; - The generic configuration and status monitoring objects which are common to all service types and PSN types (pwTable). - The PW Performance Current Table (pwPerfCurrentTable) contains PW statistics for the current 15-minute period. - The PW Performance Interval Table (pwPerfIntervalTable) contains PW statistics for historical intervals (usually 96 15-minute entries to cover a 24 hour period). - The PW Performance one day Interval Table (pwPerf1DayIntervalTable) contains PW statistics for historical intervals accumulated per day. Usually 30 1-Day entries to cover a monthly period. - The mapping table (pwIndexMappingTable) enables the reverse mapping of unique PWid parameters [peer IP, PW type and PW ID] and the pwIndex. Nadeau & Zelig Expires July 12, 2008 [Page 4] Internet-Draft PW MIB January 2008 - The mapping table (pwGenFecIndexMappingTable) enables the reverse mapping of unique PWid parameters used in genFecSignaling [pwGroupAttachmentID, pwLocalAttachmentID and pwPeerAttachmentID] and the pwIndex. This MIB module uses TCs from [RFC2578], [RFC2579], [RFC2580], [RFC2863], [RFC3411], [RFC3593], [RFC3705], [RFC4001] and [PWTC], and references [RFC3413], [RFC4623] and [RFC4720]. 7. PW-STD-MIB Module Usage An entry in the PW table (pwTable) MUST exist for all PW types (ATM, FR, Ethernet, SONET, etc.). This table holds generic parameters related to the PW creation and monitoring. A conceptual row can be created in the pwTable in one of the following ways: 1) The operator creates a row in the PwTable when configuring the node for a new service. This mode MUST be supported by the agent, and MUST be used when creating a non-signaled (manually assigned) PW. 2) The agent MAY create a row in the PwTable if a signaling message has been received from a peer node for a combination of signaling identifications parameters already unknown to the local node. This mode is OPTIONAL. 3) The agent MAY create a row in the PwTable automatically due to some auto discovery application, or based on configuration that is done through non-SNMP applications. This mode is OPTIONAL. - The agent than creates the rows in the (locally supported) performance tables and reverse mapping tables in PW-STD-MIB module. 8. Relations to Other PWE3 MIB Modules - Based on the PSN type defined for the PW, a row is created in PSN specific module (for example [PWMPLSMIB]) and associated to the PW table by the common pwIndex. - Based on the PW type defined for the PW, a row is created in service-specific module (for example [CEPMIB]) and associated to the PW table by the common pwIndex. - Unless all the necessary entries in the applicable tables have been created and all the parameters have been consistently configured in Nadeau & Zelig Expires July 12, 2008 [Page 5] Internet-Draft PW MIB January 2008 those tables, signaling cannot be performed from the local node, and the pwVcOperStatus should report 'notPresent'. 9. Relations to the IF-MIB The PW in general is not an ifIndex [RFC2863] on its own, for agent scalability reasons. The PW is typically associated via the PWE3 MIB modules to an ifIndex the PW is emulating. This ifIndex may represent a physical entity - for example a PW emulating a SONET path as in CEP: The PW itself is not an ifIndex, however the PW-STD-CEP- MIB module associates the PW to the ifIndex of the path to be emulated. In some cases, the PW will be associated to an ifIndex representing a virtual interface. An example is VPLS service where the PW emulates a logical interface of a (logical) bridge. The physical ports association to the VPLS service instance is defined in non-PW MIB modules in this case. Exception to the above MAY exist in some implementations, where it is convenient to manage the PW as an ifIndex in the ifTable. A special ifType to represent a PW virtual interface (exact number to be assigned by IANA) will be used in the ifTable in this case. When the PW is managed as an ifIndex, by default it SHOULD NOT be stacked, i.e. this ifIndex SHOULD NOT be layered above the respective PSN tunnel ifIndex or the attachment circuit ifIndex or the interface carrying the attachment circuit. Note that the ifIndex that carries the PW toward/from the PSN is in general not explicitly configured via PWE3 MIB modules except in rare cases. In most cases the PW is carried inside a PSN tunnel, and the interfaces carrying the tunnel are specified in the related MIB modules that control the PSN tunnels. 10. PW Notifications This MIB module includes notifications for PW entering the up or down state, in accordance with the guidelines for interface notifications as described in [RFC2863]. Implementers should be aware that in many systems it is desired to correlate notifications, such that notifications will not be emitted if higher hierarchy (such as ports or tunnels) notifications are already in effect. Specifically for PWs, it is anticipated that most network's equipment failures turn into lowerLayerDown state at the PW level, where higher hierarchy level notification has already been emitted. When a PW is represented as an ifIndex, it is RECOMMENDED that PW Nadeau & Zelig Expires July 12, 2008 [Page 6] Internet-Draft PW MIB January 2008 notifications will be turned off, to avoid duplication with the ifIndex status change notifications. 11. Example of the PW MIB Modules Usage In this section we provide an example of using the MIB objects described in section 7 to set up a CEP PW over MPLS PSN. 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. In this example a PW service for CEP is configured over an MPLS PSN (MPLS-TE tunnel). It uses LDP as in [RFC4447] for service set-up. For the operation in the service specific MIB modules and the PSN specific MIB modules, see the specific MIB module memo. This example is continued in the memo describing the PW-CEP-STD-MIB module (for example [CEPMIB]) and the PW-MPLS-STD-MIB module [PWMPLSMIB]).

It is indexed by pwIndex, which uniquely identifies a singular connection. A row can be created by an operator command from a management plan of a PE, by signaling or due to autodiscovery process. Operator's command can be issued via non SNMP application; in such case a row will be created implicitly by the agent. The read-create objects in this tables are divided into three categories: 1) Objects that MUST NOT be changed after row activation. These are objects that define basic properties of the PW (for example type, destination, etc.). 2) Objects that MAY be changed when the PW is Nadeau & Zelig Expires July 12, 2008 [Page 14] Internet-Draft PW MIB January 2008 defined as not active. A change of these objects involves re-signaling of the PW or it might be traffic affecting. PW not active is defined as one of the following conditions: a) The pwRowStatus is notInService(2). b) The pwRowStatus is notReady(3). c) The pwAdminStatus is down(2). If the operator needs to change one of the values for an active row, the operator can either set the pwRowStatus to notInService(2) or set pwAdminStatus to down(2). Signaling (or traffic) is initiated again upon setting the pwRowStatus to active(1) or setting the pwAdminStatus to up(1) or testing(3) respectively. 3) Objects that MAY be changed at any time. A PW MAY have an entry in the ifTable in addition to the entry in this table. In this case a special ifType for PW will be set in the ifTable, and the ifIndex in the ifTable of the PW will be set in the pwIfIndex object in this table. By default, all the read-create objects MUST NOT be changed after row activation, unless specifically indicated in the individual object description. Manual entries in this table SHOULD be preserved after a reboot, the agent MUST ensure the integrity of those entries. If the set of entries of a specific row are found to be non consistent after reboot, the PW pwOperStatus MUST be declared as notPresent(5).

Security Considerations It is clear that this MIB module is potentially useful for monitoring PW capable PEs. This MIB module 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 pwTable contains objects to configure PW parameters on a Provider Edge (PE) device. Unauthorized access to objects in this table, could result in disruption of traffic on the network. The objects pwUpDownNotifEnable and pwNotifRate control the reports from the network element to the EMS. Unauthorized access to these objects could result in disruption of configuration and status change reporting, resulting mis-view of the network conditions. The use of stronger mechanisms such as SNMPv3 security should be Nadeau & Zelig Expires July 12, 2008 [Page 62] Internet-Draft PW MIB January 2008 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 pwTable, pwPerfCurrentTable, pwPerfIntervalTable, pwPerf1DayIntervalTable, pwIndexMappingTable, pwPeerMappingTable and pwGenFecIndexMappingTable collectively show the 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 con8figured to give access to the objects only to those principals (users) that have legitimate rights to indeed GET or SET (change/create/delete) them. 15. IANA Considerations 15.1. ifType for PW IANA has beeen requested to register a value for PW in the IANAifType-MIB called ifPwType. When the assignment has been made, the RFC Editor is asked to document the value here. Nadeau & Zelig Expires July 12, 2008 [Page 63] Internet-Draft PW MIB January 2008 15.2. PW MIB Modules OBJECT IDENTIFIER values A PW may appear as ifIndex in the ifTable, and therefore it is requested below that the pwStdMIB OBJECT IDENTIFIER will be assigned under the 'transmission' subtree, as the common practice in assigning OBJECT IDENTIFIERs for MIB modules representing entities in the ifTable. All other MIB modules related to PW management SHOULD be assigned under the 'mib-2' subtree, individual request will appear in the MIB module memo IANA Considerations section. 15.3. IANA Considerations for PW-STD-MIB The MIB module in this document uses the following IANA-assigned OBJECT IDENTIFIER values recorded in the SMI Numbers registry: Descriptor OBJECT IDENTIFIER value ---------- ----------------------- pwStdMIB { transmission ZZZZ } Editor's Note (to be removed prior to publication): The IANA is requested to assign a value for "ZZZZ" under the 'transmission' subtree and to record the assignment in the SMI Numbers registry. This value SHOULD be the same value assigned for the PW ifType for representation of the PW in the ifTable. When the assignment has been made, the RFC Editor is asked to replace "ZZZZ" (here and in the MIB module) with the assigned value and to remove this note. 15.4. IANA Considerations for IANA-PWE3-MIB The MIB module in this document uses the following IANA-assigned OBJECT IDENTIFIER values recorded in the SMI Numbers registry: Descriptor OBJECT IDENTIFIER value ---------- ----------------------- ianaPwe3MIB { 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" (here and in the MIB module) with the assigned value and to remove this note.
