1.  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 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.  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.

   - 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.

7.  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.

9.  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 in section 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].

   In the PW-STD-MIB module:

   In pwTable:
   {
      pwIndex               5,

      pwType                cep,

                                       -- peer LDP entity IP addr

                                    -- report to the peer.
      pwRemoteGroupID       0xFFFF, -- Will be received by
                                    -- signaling protocol
      pwRemoteCwStatus      notKnownYet,
      pwRemoteIfMtu         0,
      pwRemoteIfString      "",
      pwRemoteCapabilities  notYetKnown,
      ..

                                    -- signaling protocol

                                    -- protocol
      pwName                "Example of CEP PW",
      pwDescr               "",
      ..

      pwAdminStatus         up,
      ..
       }

11.  IANA PWE3 MIB Module

   This section contains the initial version of the IANA-PWE3-MIB.  IANA
   has updated this MIB module based on expert review as defined in
   [RFC5226].  Each new assignment of PW type or PW PSN type made by
   IANA based on the procedures described in [RFC4446] should be
   documented in the online version of IANA-PWE3-MIB.  The current
   IANA-PWE3-MIB contains PW types as requested in [RFC4446] and
   [RFC4863].

Original Text:

[[ DESCRIPTION clause for pwFcsRetentionCfg OBJECT-TYPE ]]

         "The local configuration of Frame Check Sequence (FCS)

          PW types High-Level Data Link Control (HDLC), Point-to-Point

          This object can be changed only if the PW is not active." 
Notes:
Rationale:

The original DESCRIPTION indicated unconditional signaling of an error, whether

Pate, 'Pseudo Wire Emulation Edge-to-Edge (PWE3) Architecture' [RFC3985], Martini, L., et al, 'Pseudowire Setup and Maintenance Using the Label Distribution Protocol (LDP)' [RFC4447], and Townsley, M., et al, 'Layer Two Tunneling Protocol (Version 3)' [RFC3931]. 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. 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 inconsistent after reboot, the PW pwOperStatus MUST be declared as notPresent(5).

Notes:
Description of the pwEntry object in the same RFC states that "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.
3) Objects that MAY be changed at any time."

In further states (in tthe same description) that "By default, all the read-create objects MUST NOT be changed after row activation, unless specifically indicated in the individual object description."

pwAttachedPwIndex object is used to stitch a couple of PWs represented by two different rows in the pwTable, with the pwAttachedPwIndex value in the row representing one of them set to the pwIndex of the other one and vice versa.
Since there is no way in the SMIv2 paradigm to create two rows in the same table
in a single atomic operation, setting a this attribute in a pair of rows is only
possible when both are created. In order to do that, read-create access mode of
the pwAttachedPwIndex object has to be interpreted as ability to set its value
when the row represents an inactive PW.
In accordance with the quoted description, such an interpretation must be
explicitly specified in the description of this object.

Such a specification is missing in the current text, hence the default
interpretation of the read-create access mode is holds.
Proposed text fixes this problem.

For implementations that support the pwIndexMappingTable, a non-zero value is RECOMMENDED, even if this identifier is not signaled.

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. 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 Considerations 14.1. 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. All other MIB modules related to PW management SHOULD be assigned under the 'mib-2' subtree; individual requests will appear in the MIB module memo's IANA Considerations section. 14.3. 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 246 } 14.4. 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-2 174 } 15.
