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 that is common to all types of PSN and PW services   defined by the IETF PWE3 Working Group.2.  The Internet-Standard Management Framework   For a detailed overview of the documents that describe the current   Internet-Standard Management Framework, please refer tosection 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 MIBNadeau & Zelig              Standards Track                     [Page 2]

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 inRFC 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.  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 a service-   specific module, which is dependent on the emulated signal type.   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 module is a 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.5.  Structure of the MIB Module   The MIB module consists of six tables:   - The generic configuration and status monitoring objects that 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.Nadeau & Zelig              Standards Track                     [Page 3]

RFC 5601                         PW MIB                        July 2009   - 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 1-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 the unique PWid parameters [peer IP, PW type, and PW ID] and the     pwIndex.   - 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 Textual Conventions from [RFC2578], [RFC2579],   [RFC2580], [RFC2863], [RFC3411], [RFC3593], [RFC3705], [RFC4001], and   [RFC5542], and references [RFC3413], [RFC4623], and [RFC4720].6.  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 with signaling identification      parameters that are not already known to the local node (i.e.,      there is no related entry created by the operator with matching      parameters).  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 then creates the rows in the (locally supported)        performance tables and reverse-mapping tables in PW-STD-MIB        module.Nadeau & Zelig              Standards Track                     [Page 4]

RFC 5601                         PW MIB                        July 20097.  Relations to Other PWE3 MIB Modules   - Based on the PSN type defined for the PW, a row is created in the     PSN-specific module (for example, [RFC5602]) and associated to the     PW table by the common pwIndex.   - Based on the PW type defined for the PW, a row is created in the     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     those tables, signaling cannot be performed from the local node,     and the pwVcOperStatus should report 'notPresent'.8.  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 Circuit Emulation Service over Packet (CEP).  In that   case, 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 Virtual Private LAN Service (VPLS)   where the PW emulates a logical interface of a (logical) bridge.  The   physical ports' association to the VPLS instance is defined in the   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 (246) 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 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.Nadeau & Zelig              Standards Track                     [Page 5]

RFC 5601                         PW MIB                        July 20099.  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 notifications from a higher   level (such as ports or tunnels) 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 a notification   has already been emitted from a higher level.   When a PW is represented as an ifIndex, it is RECOMMENDED that PW   notifications be turned off, to avoid duplication with the ifIndex   status change notifications.10.  Example of the PW MIB Modules Usage   In this section, we provide an example of using the MIB objects   described insection 7 to set up a CEP PW over Multiprotocol Label   Switching (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 setup.   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 [RFC5602].Nadeau & Zelig              Standards Track                     [Page 6]

This MIB module enables the use of any underlying packet         switched network (PSN).  MIB nodules that will support         PW operations over specific PSN types are defined in         separate memos.         The indexes for this MIB module are also used to index the         PSN-specific tables and the PW-specific tables.  The PW Type         dictates which PW-specific MIB module to use.

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 auto-           discovery process.  An operator's command can be issued via           a non-SNMP application; in such case, a row will be created           implicitly by the agent.           The read-create objects in this table 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              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.Nadeau & Zelig              Standards Track                    [Page 14]

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 inconsistent 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 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 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      considered where possible.  Specifically, SNMPv3 VACM and USM MUST      be used with any v3 agent that 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.Nadeau & Zelig              Standards Track                    [Page 62]

RFC 5601                         PW MIB                        July 2009   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 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.14.  IANA Considerations14.1.  ifType for PW   IANA has assigned a value (246) for PW in the IANAifType-MIB called   ifPwType.14.2.  PW MIB Modules OBJECT IDENTIFIER Values   A PW may appear as ifIndex in the ifTable, and therefore the pwStdMIB   OBJECT IDENTIFIER has been assigned under the 'transmission' subtree,   as the common practice in assigning OBJECT IDENTIFIERs for MIB   modules representing entities in the ifTable.Nadeau & Zelig              Standards Track                    [Page 63]
