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 describes managed objects for modeling Generalized   Multiprotocol Label Switching (GMPLS) [RFC3945] based traffic   engineering (TE).  The tables and objects defined in this document   extend those defined in the equivalent document for MPLS traffic   engineering [RFC3812], and management of GMPLS traffic engineering is   built on management of MPLS traffic engineering.   The MIB modules in this document should be used in conjunction with   the companion document [RFC4803] for GMPLS-based traffic engineering   configuration and management.   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 inBCP 14, [RFC2119].Nadeau & Farrel             Standards Track                     [Page 2]

RFC 4802                      GMPLS TE MIB                 February 20071.1.  Migration Strategy   MPLS-TE Label Switched paths (LSPs) may be modeled and managed using   the MPLS-TE-STD-MIB module [RFC3812].   Label Switching Routers (LSRs) may be migrated to model and manage   their TE LSPs using the MIB modules in this document in order to   migrate the LSRs to GMPLS support, or to take advantage of additional   MIB objects defined in these MIB modules that are applicable to   MPLS-TE.   The GMPLS TE MIB module (GMPLS-TE-STD-MIB) defined in this document   extends the MPLS-TE-STD-MIB module [RFC3812] through a series of   augmentations and sparse augmentations of the MIB tables.  The only   additions are for support of GMPLS or to support the increased   complexity of MPLS and GMPLS systems.   In order to migrate from MPLS-TE-STD-MIB support to GMPLS-TE-STD-MIB   support, an implementation needs only to add support for the   additional tables and objects defined in GMPLS-TE-STD-MIB.  The   gmplsTunnelLSPEncoding may be set to tunnelLspNotGmpls to allow an   MPLS-TE LSP tunnel to benefit from the additional objects and tables   of GMPLS-LSR-STD-MIB without supporting the GMPLS protocols.   The companion document for modeling and managing GMPLS-based LSRs   [RFC4803] extends the MPLS-LSR-STD-MIB module [RFC3813] with the same   intentions.   Textual conventions are defined in [RFC3811] and the IANA-GMPLS-TC-   MIB module.2.  Terminology   This document uses terminology from the MPLS architecture document   [RFC3031], from the GMPLS architecture document [RFC3945], and from   the MPLS Traffic Engineering MIB [RFC3812].  Some frequently used   terms are described next.   An explicitly routed LSP (ERLSP) is referred to as a GMPLS tunnel.   It consists of in-segment(s) and/or out-segment(s) at the   egress/ingress LSRs, each segment being associated with one GMPLS-   enabled interface.  These are also referred to as tunnel segments.   Additionally, at an intermediate LSR, we model a connection as   consisting of one or more in-segments and/or one or more out-   segments.  The binding or interconnection between in-segments and   out-segments is performed using a cross-connect.Nadeau & Farrel             Standards Track                     [Page 3]

RFC 4802                      GMPLS TE MIB                 February 2007   These segment and cross-connect objects are defined in the MPLS Label   Switching Router MIB (MPLS-LSR-STD-MIB) [RFC3813], but see also the   GMPLS Label Switching Router MIB (GMPLS-LSR-STD-MIB) [RFC4803] for   the GMPLS-specific extensions to these objects.3.  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 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].4.  Outline   Support for GMPLS traffic-engineered tunnels requires the following   configuration.   -  Setting up tunnels with appropriate MPLS configuration parameters      using [RFC3812].   -  Extending the tunnel definitions with GMPLS configuration      parameters.   -  Configuring loose and strict source routed tunnel hops.   These actions may need to be accompanied with corresponding actions   using [RFC3813] and [RFC4803] to establish and configure tunnel   segments, if this is done manually.  Also, the in-segment and out-   segment performance tables, mplsInSegmentPerfTable and   mplsOutSegmentPerfTable [RFC3813], should be used to determine   performance of the tunnels and tunnel segments, although it should be   noted that those tables may not be appropriate for measuring   performance on some types of GMPLS links.4.1.  Summary of GMPLS Traffic Engineering MIB Module   The following tables contain MIB objects for performing the actions   listed above when they cannot be performed solely using MIB objects   defined in MPLS-TE-STD-MIB [RFC3812].Nadeau & Farrel             Standards Track                     [Page 4]

RFC 4802                      GMPLS TE MIB                 February 2007   -  Tunnel table (gmplsTunnelTable) for providing GMPLS-specific      tunnel configuration parameters.   -  Tunnel hop, actual tunnel hop, and computed tunnel hop tables      (gmplsTunnelHopTable, gmplsTunnelARHopTable, and      gmplsTunnelCHopTable) for providing additional configuration of      strict and loose source routed tunnel hops.   -  Performance and error reporting tables      (gmplsTunnelReversePerfTable and gmplsTunnelErrorTable).   These tables are described in the subsequent sections.   Additionally, the GMPLS-TE-STD-MIB module contains a new   notification.   -  The GMPLS Tunnel Down Notification (gmplsTunnelDown) should be      used for all GMPLS tunnels in place of the mplsTunnelDown      notification defined in [RFC3812].  An implementation must not      issue both the gmplsTunnelDown and the mplsTunnelDown      notifications for the same event.  As well as indicating that a      tunnel has transitioned to operational down state, this new      notification indicates the cause of the failure.5.  Brief Description of GMPLS TE MIB Objects   The objects described in this section support the functionality   described in [RFC3473] and [RFC3472] for GMPLS tunnels.  The tables   support both manually configured and signaled tunnels.5.1.  gmplsTunnelTable   The gmplsTunnelTable extends the MPLS traffic engineering MIB module   (MPLS-TE-STD-MIB [RFC3812]) to allow GMPLS tunnels to be created   between an LSR and a remote endpoint, and existing GMPLS tunnels to   be reconfigured or removed.   Note that we only support point-to-point tunnel segments, although   multipoint-to-point and point-to-multipoint connections are supported   by an LSR acting as a cross-connect.   Each tunnel can thus have one out-segment originating at an LSR   and/or one in-segment terminating at that LSR.   Three objects within this table utilize enumerations in order to map   to enumerations that are used in GMPLS signaling.  In order to   protect the GMPLS-TE-STD-MIB module from changes (in particular,   extensions) to the range of enumerations supported by the signalingNadeau & Farrel             Standards Track                     [Page 5]

RFC 4802                      GMPLS TE MIB                 February 2007   protocols, these MIB objects use textual conventions with values   maintained by IANA.  For further details, see the IANA Considerations   section of this document.5.2.  gmplsTunnelHopTable   The gmplsTunnelHopTable is used to indicate additional parameters for   the hops, strict or loose, of a GMPLS tunnel defined in the   gmplsTunnelTable, when it is established using signaling.  Multiple   tunnels may share hops by pointing to the same entry in this table.5.3.  gmplsTunnelARHopTable   The gmplsTunnelARHopTable is used to indicate the actual hops   traversed by a tunnel as reported by the signaling protocol after the   tunnel is set up.  The support of this table is optional since not   all GMPLS signaling protocols support this feature.5.4.  gmplsTunnelCHopTable   The gmplsTunnelCHopTable lists the actual hops computed by a   constraint-based routing algorithm based on the gmplsTunnelHopTable.   The support of this table is optional since not all implementations   support computation of hop lists using a constraint-based routing   protocol.5.5.  gmplsTunnelErrorTable   The gmplsTunnelErrorTable provides access to information about the   last error that occurred on each tunnel known about by the MIB.  It   indicates the nature of the error and when and how it was reported,   and it can give recovery advice through an admin string.5.6.  gmplsTunnelReversePerfTable   The gmplsTunnelReversePerfTable provides additional counters to   measure the performance of bidirectional GMPLS tunnels in which   packets are visible.  It supplements the counters in   mplsTunnelPerfTable and augments gmplsTunnelTable.   Note that not all counters may be appropriate or available for some   types of tunnel.Nadeau & Farrel             Standards Track                     [Page 6]

RFC 4802                      GMPLS TE MIB                 February 20075.7.  Use of 32-bit and 64-bit Counters   64-bit counters are provided in the GMPLS-TE-STD-MIB module for   high-speed interfaces where the use of 32-bit counters might be   impractical.  The requirements on the use of 32-bit and 64-bit   counters (copied verbatim from [RFC2863]) are as follows:      For interfaces that operate at 20,000,000 (20 million) bits per      second or less, 32-bit byte and packet counters MUST be supported.      For interfaces that operate faster than 20,000,000 bits/second,      and slower than 650,000,000 bits/second, 32-bit packet counters      MUST be supported and 64-bit octet counters MUST be supported.      For interfaces that operate at 650,000,000 bits/second or faster,      64-bit packet counters AND 64-bit octet counters MUST be      supported.6.  Cross-referencing to the gmplsLabelTable   The gmplsLabelTable is found in the GMPLS-LABEL-STD-MIB module in   [RFC4803] and provides a way to model labels in a GMPLS system where   labels might not be simple 32-bit integers.   The hop tables in this document (gmplsTunnelHopTable,   gmplsTunnelCHopTable, and gmplsTunnelARHopTable) and the segment   tables in [RFC3813] (mplsInSegmentTable and mplsOutSegmentTable)   contain objects with syntax MplsLabel.   MplsLabel (defined in [RFC3811]) is a 32-bit integer that is capable   of representing any MPLS Label and most GMPLS Labels.  However, some   GMPLS Labels are larger than 32 bits and may be of arbitrary length.   Furthermore, some labels that may be safely encoded in 32 bits are   constructed from multiple sub-fields.  Additionally, some GMPLS   technologies support the concatenation of individual labels to   represent a data flow carried as multiple sub-flows.   These GMPLS cases require that something other than a simple 32-bit   integer be made available to represent the labels.  This is achieved   through the gmplsLabelTable contained in the GMPLS-LABEL-STD-MIB   [RFC4803].   The tables in this document and [RFC3813] that include objects with   syntax MplsLabel also include companion objects that are row   pointers.  If the row pointer is set to zeroDotZero (0.0), then an   object of syntax MplsLabel contains the label encoded as a 32-bit   integer.  But otherwise the row pointer indicates a row in another   MIB table that includes the label.  In these cases, the row pointer   may indicate a row in the gmplsLabelTable.Nadeau & Farrel             Standards Track                     [Page 7]

RFC 4802                      GMPLS TE MIB                 February 2007   This provides both a good way to support legacy systems that   implement MPLS-TE-STD-MIB [RFC3812], and a significant simplification   in GMPLS systems that are limited to a single, simple label type.   Note that gmplsLabelTable supports concatenated labels through the   use of a label sub-index (gmplsLabelSubindex).7.  Example of GMPLS Tunnel Setup   This section contains an example of which MIB objects should be   modified to create a GMPLS tunnel.  This example shows a best effort,   loosely routed, bidirectional traffic engineered tunnel, which spans   two hops of a simple network, uses Generalized Label requests with   Lambda encoding, has label recording and shared link layer   protection.  Note that these objects should be created on the "head-   end" LSR.

We have used the fictitious LSR identified by "192.0.2.2"   as our tail-end router.

Security Considerations   It is clear that the MIB modules described in this document in   association with MPLS-TE-STD-MIB [RFC3812] are potentially useful for   monitoring of MPLS and GMPLS tunnels.  These MIB modules 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 these MIB modules   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:Nadeau & Farrel             Standards Track                    [Page 47]

RFC 4802                      GMPLS TE MIB                 February 2007   o  the gmplsTunnelTable and gmplsTunnelHopTable collectively contain      objects to provision GMPLS tunnels interfaces at their ingress      LSRs.  Unauthorized write access to objects in these tables could      result in disruption of traffic on the network.  This is      especially true if a tunnel has already been established.   Some of the readable objects in these MIB modules (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 gmplsTunnelTable, gmplsTunnelHopTable, gmplsTunnelARHopTable,      gmplsTunnelCHopTable, gmplsTunnelReversePerfTable, and      gmplsTunnelErrorTable collectively show the tunnel network      topology and status.  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 these MIB modules.   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.10.

IANA has been requested   to manage that namespace in the SMI Numbers registry [RFC3811].  New   assignments can only be made via a Standards Action as specified in   [RFC2434].11.2.  Dependence on IANA MIB Modules   Three MIB objects in the GMPLS-TE-STD-MIB module defined in this   document (gmplsTunnelLSPEncoding, gmplsTunnelSwitchingType, and   gmplsTunnelGPid) use textual conventions imported from the IANA-   GMPLS-TC-MIB module.  The purpose of defining these textual   conventions in a separate MIB module is to allow additional values to   be defined without having to issue a new version of this document.   The Internet Assigned Numbers Authority (IANA) is responsible for the   assignment of all Internet numbers; it will administer the values   associated with these textual conventions.Nadeau & Farrel             Standards Track                    [Page 49]
