Changes Since Last Version This is the first version of this draft. It builds upon draft-nadeau-mpls-gmpls-te-mib-00.txt and is modeled on draft-ietf-mpls-te-mib-07.txt. The main differences are the addition of GMPLS parameters and the abstraction of labels through the gmplsLabelTable. Nadeau, et al. [Page 2 ] draft-nadeau-ccamp-gmpls-te-mib-00.txt November 2001 1.2. Pending Work The following work items have been identified for this draft. They will be addressed in a future version. - Clarify which objects can be modified when rowStatus and adminStatus are set to active? - Expand conformance statements to give one for monitoring only, and one for monitoring and control. - Update examples and provide more detail. - Bring references up to date, include all drafts referenced from this document, and exclude those that are not referenced. - Provide objects or tables to support getNextIndex for all arbitrary indexes. - Consider a way to expose tunnel head, tunnel tail, and tunnel transit entries through distinct indexing or tables. - Provide support for configuring tunnel resources in GMPLS systems. For example, SONET/SDH or G.709. This might be done through an arbitrary RowPointer to an external MIB. - Last error {MIB code, timestamp, protocol codes}. - Link Ids in EROs and RROs for use of bundled links. - Crankback request and reported information. - Control and reporting of upstream and downstream Notify Recipients. - Add support for control and reporting of GMPLS Administrative Status object. - Update enumerated types in line with latest GMPLS drafts. - Apply bug fixes in line with updates to [TCMIB]. - Resolve ownership of enumerated types that are also defined in GMPLS or routing drafts. (See "Ed Note:" in text.) These could be owned by IANA, imported from another MIB, or manually kept in step here. If they are not maintained externally then they are likely to diverge and MIB implementations will need to provide mappings. Nadeau, et al. [Page 3 ] draft-nadeau-ccamp-gmpls-te-mib-00.txt November 2001 2. Introduction This memo defines an experimental portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it describes managed objects for Multi- Protocol Label Switching (MPLS) [RFC3031] and Generalized Multi-Protocol Label Switching (GMPLS) [GMPLSArch] based traffic engineering. Comments should be made directly to the CCAMP mailing list at ccamp@ops.ietf.org. This memo does not, in its draft form, specify a standard for the Internet community. 2.1. Migration Strategy This MIB is built upon the traffic engineering MIB defined for use with MPLS [TEMIB]. The only changes made are additions for support of GMPLS or changes that are necessary to support the increased complexity of a GMPLS system. In all cases, these changes have been made such that migration from [TEMIB] to this MIB will be as simple as possible. Note that this MIB may be used in systems that support MPLS, GMPLS or both. This MIB may be seen as a replacement for the MPLS TE MIB [TEMIB] in systems which support GMPLS, but it is not a requirement that it replace the MPLS TE MIB in systems that only support MPLS. The companion document modeling and managing GMPLS based LSRs [GMPLSLSRMIB] is based on the MPLS LSR MIB [LSRMIB] with the same intentions. It is not expected that a system would mix MPLS and GMPLS MIBs. Textual conventions and OBJECT-IDENTIFIERS are defined in [GMPLSTCMIB] which extends the set of textual conventions defined in [TCMIB]. See section 11.1 for a description of how the gmplsLabelTable may be omitted in systems that support MPLS only. Nadeau, et al. [Page 4 ] draft-nadeau-ccamp-gmpls-te-mib-00.txt November 2001 3. Terminology This document uses terminology from the MPLS architecture document [RFC3031] and GMPLS Label Switch Router MIB [GMPLSLSRMIB]. It imports constructs from the GMPLS textual conventions MIB [GMPLSTCMIB] and from the MPLS textual conventions MIB [TCMIB]. Some frequently used terms are described next. An explicitly routed LSP (ERLSP) is referred to as an MPLS tunnel. It consists of one in-segment and/or one out-segment at the ingress/egress LSRs, each segment being associated with one MPLS 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 in performed using a cross-connect. These objects are defined in the GMPLS Label Switch Router MIB [GMPLSLSRMIB]. 4. The SNMP Management Framework The SNMP Management Framework presently consists of five major components: - An overall architecture, described in RFC 2571 [RFC2571]. - 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]. - 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]. - 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 Nadeau, et al. [Page 5 ] draft-nadeau-ccamp-gmpls-te-mib-00.txt November 2001 and associated PDU formats is described in RFC 1905 [RFC1905]. - 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. 5. Feature List The GMPLS traffic engineering MIB is designed to satisfy the following requirements and constraints. - The MIB supports MPLS and GMPLS tunnels. - The MIB supports configuration of point-to-point unidirectional and bidirectional tunnels. - Tunnels need not be interfaces, but it is possible to configure a tunnel as an interface. - The MIB supports manually configured tunnels as well as those set up via an MPLS or GMPLS signaling protocol. - The MIB supports persistent as well as non-persistent tunnels. Nadeau, et al. [Page 6 ] draft-nadeau-ccamp-gmpls-te-mib-00.txt November 2001 6. Outline Support for MPLS or GMPLS traffic-engineered tunnels requires the following configuration. - Setting up tunnels along with appropriate MPLS or GMPLSconfiguration parameters. - Configuring tunnel loose and strict source routed hops. These actions may need to be accompanied with corresponding actions using [GMPLSLSRMIB] to establish and configure tunnel segments, if this is done manually. Also, the in-segment and out-segment performance tables, mplsInSegmentPerfTable and mplsOutSegmentPerfTable [GMPLSLSRMIB], should be used to determine performance of the tunnels and tunnel segments. 6.1. Summary of GMPLS Traffic Engineering MIB The MIB objects for performing these actions consist of the following tables. - Tunnel Table (gmplsTunnelTable) for setting up MPLS or GMPLS tunnels. - Resource table (gmplsTunnelResourceTable) for setting up the tunnel resources. - Tunnel specified, actual, and computed hop tables (gmplsTunnelHopTable, gmplsTunnelARHopTable, and gmplsTunnelCHopTable) for strict and loose source routed tunnel hops. - CRLDP resource table (mplsTunnelCRLDPResTable) for specifying resource objects applicable only to tunnels signaled using CRLDP. These tables are described in the subsequent sections. 7. Brief Description of MIB Objects The objects described in this section support the functionality described in documents [RSVPTE] and [CRLDP] for MPLS tunnels and the functionality described in [GMPLSRSVPTE] and [GMPLSCRLDP] for GMPLS tunnels. The tables support both manually configured and signaled tunnels. Nadeau, et al. [Page 7 ] draft-nadeau-ccamp-gmpls-te-mib-00.txt November 2001 7.1. gmplsTunnelTable The mplsTunnelTable allows new MPLS and GMPLS tunnels to be created between an LSR and a remote endpoint, and existing tunnels to be reconfigured or removed. Note that we only support point-to-point tunnel segments, although multi-point-to-point and point-to-multi-point 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. gmplsTunnelTable does not define the in and out segments forming the tunnel. Instead, these are defined by creating rows in the in-segment and out-segment tables, defining relationships in the cross-connect table and referring to these rows in the gmplsTunnelTable using a cross-connect index, gmplsTunnelXCIndex. These segment and cross-connect related objects are defined in [GMPLSLSRMIB]. 7.2. gmplsTunnelResourceTable The gmplsTunnelResourceTable is used to indicate the resources required for a tunnel. Multiple tunnels may share the same resources by pointing to the same entry in this table. Tunnels that do not share resources must point to separate entries in this table. 7.3. gmplsTunnelHopTable The gmplsTunnelHopTable is used to indicate the hops, strict or loose, for an MPLS or GMPLS tunnel defined in gmplsTunnelTable, when it is established using signaling. Multiple tunnels may share the same hops by pointing to the same entry in this table. Each row also has a secondary index, gmplsTunnelHopIndex, corresponding to the next hop of this tunnel. The scalar mplsTunnelMaxHops indicates the maximum number of hops that can be specified on each tunnel supported by this LSR. 7.3.1 Determining next entries in gmplsTunnelHopTable Two tables (gmplsTunnelHopPathOptionIndexNextTable and gmplsTunnelHopIndexNextTable) can be used in association with a scalar (gmplsTunnelHopListIndexNext) to determine the next available indexing values in the gmplsTunnelHopTable. Nadeau, et al. [Page 8 ] draft-nadeau-ccamp-gmpls-te-mib-00.txt November 2001 7.4. gmplsTunnelARHopTable The gmplsTunnelARHopTable is used to indicate the actual hops traversed by a tunnel as reported by the signaling protocol after the tunnel is setup. The support of this table is optional since not all MPLS/GMPLS signaling protocols support this feature. 7.5. 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 list using a constraint-based routing protocol. 7.6. gmplsTunnelPerfTable gmplsTunnelPerfTable provides several counters to measure the performance of the MPLS and GMPLS tunnels. This table augments gmplsTunnelTable. Note that not all counters may be appropriate or available for some types of tunnel. 7.7. gmplsTunnelCRLDPResTable The gmplsTunnelCRLDPResTable contains additional resource information for those tunnels that are signaled using CRLDP [CRLDP]. This is a sparse extension to mplsTunnelResourceTable and is also indexed by gmplsTunnelResourceIndex. As with gmplsTunnelResourceTable, multiple tunnels may share the same resources by pointing to the same entry in this table. Tunnels that do not share resources must point to separate entries in this table. 8. Application of the Interface Group to MPLS and GMPLS Tunnels This memo contains media-specific extensions to the Interfaces Group for managing MPLS and GMPLS Tunnels as logical interfaces and assumes the interpretation of the Interfaces Group to be in accordance with [RFC2233] which states that the interfaces table (ifTable) contains information on the managed resource's interfaces and that each sub-layer below the internetwork layer of a network interface is considered an interface. Thus, the MPLS interface is represented as an entry in the ifTable (from this perspective, MPLS and GMPLS should be considered to Nadeau, et al. [Page 9 ] draft-nadeau-ccamp-gmpls-te-mib-00.txt November 2001 operate at the MPLS interface). The interrelation of entries in the ifTable is defined by the Interfaces Stack Group defined in [RFC2233]. MPLS and GMPLS tunnels may themselves be used as interfaces. When using tunnels as interfaces, the interface stack table might appear as follows: +------------------------------------------------+ | MPLS tunnel interface ifType = mplsTunnel(150) | +------------------------------------------------+ | MPLS interface ifType = mpls(166) | +------------------------------------------------+ | Underlying layer | +------------------------------------------------+ In the above diagram, "Underlying Layer" refers to the ifIndex of any interface type, which has been defined for MPLS interworking. Examples include ATM, Frame Relay, and Ethernet. 8.1. Support of the MPLS Tunnel Interface by ifTable Some specific interpretations of ifTable for those MPLS tunnels represented as interfaces follow: Object Use for the MPLS tunnel. ifIndexEach MPLS tunnel is represented by an ifEntry. ifDescr Description of the MPLS tunnel. ifType The value that is allocated for MPLS tunnel is 150. ifSpeed The total bandwidth in bits per second for use by the MPLS tunnel. ifPhysAddress Unused. ifAdminStatus See [RFC2233]. ifOperStatus Assumes the value down(2) if the MPLS tunnel is down. ifLastChange See [RFC2233]. ifInOctets The number of octets received over the MPLS tunnel. ifOutOctets The number of octets transmitted over the MPLS tunnel. Nadeau, et al. [Page 10] draft-nadeau-ccamp-gmpls-te-mib-00.txt November 2001 ifInErrors The number of labeled packets dropped due to uncorrectable errors. ifInUnknownProtos The number of received packets discarded during packet header validation, including packets with unrecognized label values. ifOutErrors See [RFC2233]. ifName Textual name (unique on this system) of the MPLS tunnel or an octet string of zero length. ifLinkUpDownTrapEnable Default is disabled (2). ifConnectorPresent Set to false (2). ifHighSpeed See [RFC2233]. ifHCInOctets The 64-bit version of ifInOctets; supported if required by the compliance statements in [RFC2233]. ifHCOutOctets The 64-bit version of ifOutOctets; supported if required by the compliance statements in [RFC2233]. ifAlias The non-volatile 'alias' name for the MPLS tunnel as specified by a network manager. 9. Example of MPLS Tunnel Setup -- This section slightly out of date This section contains an example of which MIB objects should be modified to create a best effort, loosely routed, unidirectional traffic engineered tunnel, which spans two hops of a simple network. Note that these objects should be created on the "head- end" LSR. This example is for an MPLS tunnel. It does not use any features of GMPLS. In gmplsTunnelTable: { gmplsTunnelIndex = 1, gmplsTunnelInstance = 1, gmplsTunnelIngressLSRId = 123.123.125.1, gmplsTunnelEgressLSRId = 123.123.126.1, Nadeau, et al. [Page 11] draft-nadeau-ccamp-gmpls-te-mib-00.txt November 2001 gmplsTunnelName= "My first tunnel", gmplsTunnelDescr = "Here to there", gmplsTunnelIsIf= true (1), gmplsTunnelXCPointer = mplsXCIndex.2.0.0.15, gmplsTunnelSignallingProto = none (1), gmplsTunnelSetupPrio = 0, gmplsTunnelHoldingPrio = 0, gmplsTunnelAttributes = 0, gmplsTunnelOwner = snmp (1), gmplsTunnelLocalProtectInUse = false (0), gmplsTunnelResourcePointer = mplsTunnelResourceIndex.5, gmplsTunnelInstancePriority= 1, gmplsTunnelHopTableIndex= 1, gmplsTunnelPrimaryInstance = 0, gmplsTunnelIncludeAnyAffinity = 0, gmplsTunnelIncludeAllAffinity = 0, gmplsTunnelExcludeAnyAffinity = 0, gmplsTunnelPathInUse = 1, gmplsTunnelRole= head(1), gmplsTunnelRowStatus = createAndGo (4) } In gmplsTunnelResourceTable: { gmplsTunnelResourceIndex = 5, gmplsTunnelResourceMaxRate= 0, gmplsTunnelResourceMeanRate = 0, gmplsTunnelResourceMaxBurstSize = 0, gmplsTunnelResourceRowStatus = createAndGo (4) } The next two instances of gmplsTunnelHopEntry are used to denote the hops this tunnel will take across the network. The following denotes the beginning of the network, or the first hop. We have used the fictitious LSR identified by "123.123.125.1" as our example head-end router. In gmplsTunnelHopTable: { gmplsTunnelHopListIndex = 1, gmplsTunnelPathOptionIndex = 1, gmplsTunnelHopIndex = 1, gmplsTunnelHopAddrType = 1, gmplsTunnelHopIpv4Addr = 123.123.125.1, gmplsTunnelHopIpv4PrefixLen= 9, gmplsTunnelHopType= loose (2), gmplsTunnelHopRowStatus = createAndGo (4) } The following denotes the end of the network, or the last hop in our example. We have used the fictitious LSR identified by "123.123.126.1" as our end router. Nadeau, et al. [Page 12] draft-nadeau-ccamp-gmpls-te-mib-00.txt November 2001 In gmplsTunnelHopTable: { gmplsTunnelHopListIndex = 1, gmplsTunnelPathOptionIndex = 1, gmplsTunnelHopIndex = 2, gmplsTunnelHopAddrType = 1, gmplsTunnelHopIpv4Addr = 123.123.126.1, gmplsTunnelHopIpv4PrefixLen= 9, gmplsTunnelHopType= loose (2), gmplsTunnelHopRowStatus = createAndGo (4) } 10. Example of GMPLS Tunnel Setup -- This section needs further work This section contains an example of which MIB objects should be modified to create a best effort, loosely routed, bidirectional traffic engineered tunnel, which spans two hops of a simple network and uses Generalized Label requests with Lambda encoding and shared link layer protection. Note that these objects should be created on the "head-end" LSR. In gmplsTunnelTable: { gmplsTunnelIndex = 1, gmplsTunnelInstance = 1, gmplsTunnelIngressLSRId = 123.123.125.1, gmplsTunnelEgressLSRId = 123.123.126.1, gmplsTunnelName= "My first tunnel", gmplsTunnelDescr = "Here to there and back again", gmplsTunnelIsIf= true (1), gmplsTunnelXCPointer = gmplsXCIndex.3.0.0.12, gmplsTunnelSignallingProto = none (1), gmplsTunnelSetupPrio = 0, gmplsTunnelHoldingPrio = 0, gmplsTunnelAttributes= 0, gmplsTunnelOwner = snmp (1), gmplsTunnelLocalProtectInUse = false (0), gmplsTunnelResourcePointer = gmplsTunnelResourceIndex.6, gmplsTunnelInstancePriority= 1, gmplsTunnelHopTableIndex= 1, gmplsTunnelPrimaryInstance = 0, gmplsTunnelIncludeAnyAffinity = 0, gmplsTunnelIncludeAllAffinity = 0, gmplsTunnelExcludeAnyAffinity = 0, gmplsTunnelPathInUse = 1, gmplsTunnelRole= head(1), gmplsTunnelRowStatus = createAndGo (4), gmplsTunnelLSPEncoding = tunnelLspLambda (8), Nadeau, et al. [Page 13] draft-nadeau-ccamp-gmpls-te-mib-00.txt November 2001 gmplsTunnelLinkProtection = shared (2), gmplsTunnelGPid= lambda (37), gmplsTunnelDirection = bidirectional (1) } Entries in the gmplsTunnelResourceTable and gmplsTunnelHopTable are created and activated at this time. In gmplsTunnelResourceTable: { gmplsTunnelResourceIndex = 6, gmplsTunnelResourceMaxRate= 0, gmplsTunnelResourceMeanRate = 0, gmplsTunnelResourceMaxBurstSize = 0, gmplsTunnelResourceRowStatus = createAndGo (4) } The next two instances of gmplsTunnelHopEntry are used to denote the hops this tunnel will take across the network. The following denotes the beginning of the network, or the first hop. We have used the fictitious LSR identified by "123.123.125.1" as our example head-end router. This hop explicitly specifies the labels that will be used for the out segment on the forward path and the in segment on the reverse path. In gmplsTunnelHopTable: { gmplsTunnelHopListIndex= 1, gmplsTunnelPathOptionIndex= 1, gmplsTunnelHopIndex = 1, gmplsTunnelHopAddrType = 1, gmplsTunnelHopIpv4Addr = 123.123.125.1, gmplsTunnelHopIpv4PrefixLen = 9, gmplsTunnelHopType = strict (1), gmplsTunnelHopRowStatus= createAndGo (4), gmplsTunnelHopLabelStatuses = forwardPresent(0)+reversePresent(1), gmplsTunnelHopExplicitLabel = gmplsLabelIndex.2756132, gmplsTunnelHopExplicitReverseLabel = gmplsLabelIndex.65236213 } The following denotes the end of the network, or the last hop in our example. We have used the fictitious LSR identified by "123.123.126.1" as our end router. In gmplsTunnelHopTable: { gmplsTunnelHopListIndex= 1, gmplsTunnelPathOptionIndex= 1, Nadeau, et al. [Page 14] draft-nadeau-ccamp-gmpls-te-mib-00.txt November 2001 gmplsTunnelHopIndex = 2, gmplsTunnelHopAddrType = 1, gmplsTunnelHopIpv4Addr = 123.123.126.1, gmplsTunnelHopIpv4PrefixLen = 9, gmplsTunnelHopType = loose (2), gmplsTunnelHopRowStatus= createAndGo (4), gmplsTunnelHopLabelStatuses = 0 } 11. The Use of RowPointer and Other Cross-References 11.1. RowPointer RowPointer is a textual convention used to identify a conceptual row in an SNMP Table by pointing to one of its objects. In this MIB, in gmplsTunnelTable, the objects gmplsTunnelXCPointer and gmplsTunnelResourcePointer are of type RowPointer. The object gmplsTunnelXCPointer points to a specific entry in the gmplsXCTable [GMPLSLSRMIB]. This entry in the gmplsXCTable is the associated LSP for the given tunnel entry. The object gmplsTunnelResourcePointer points to a specific entry in a traffic parameter table. An example of such a traffic parameter table is gmplsTunnelResourceTable. It indicates a specific instance of a traffic parameter entry that is associated with a given tunnel entry. 11.2. Cross-referencing to the gmplsLabelTable The gmplsLabelTable [GMPLSLABELMIB] 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 (gmplsHopTable, gmplsCHopTable and gmplsARHopTable) use arbitrary indexes to point to entries in the gmplsLabelTable to indicate specific label values. Since the primary index into gmplsLabelTabel is a simple 32 bit integer (gmplsLabelIndex), in systems where the nature of a label is well-known, and where the label can safely be encoded as a 32 bit integer (for example a conventional MPLS system), the gmplsLabelTable does not need to be supported and the pointers to the gmplsLabelTable (gmplsTunnelHopExplicitLabel, gmplsTunnelHopExplicitReverseLabel, gmplsTunnelCHopExplicitLabel, gmplsTunnelCHopExplicitReverseLabel, gmplsTunnelARHopExplicitLabel, gmplsTunnelARHopExplicitReverseLabel) may be replaced with the direct label values. This provides both a good way to support legacy systems Nadeau, et al. [Page 15] draft-nadeau-ccamp-gmpls-te-mib-00.txt November 2001 that implement the previous version of this MIB [TEMIB], 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 sub-label index (gmplsSublabelIndex). 12.

Security Considerations There are a number of management objects defined in this MIB that have 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. There are a number of managed objects in this MIB that may contain information that may be sensitive from a business perspective, in that they represent a customer's interface to the MPLS network. Allowing uncontrolled access to these objects could result in malicious and unwanted disruptions of network traffic or incorrect configurations for these customers. There are no objects that are particularly sensitive in their own right, such as passwords or monetary amounts. It is thus important to control even GET access to these objects and possibly to even encrypt the values of these object when sending them over the network via SNMP. Not all versions of SNMP provide features for such a secure environment. At this writing, no security holes have been identified beyond those that SNMP Security [SNMPArch] is itself intended to address. These relate to primarily controlled access to sensitive information and the ability to configure a device - or which might result from operator error, which is beyond the scope of any security architecture. SNMPv1 or SNMPv2 are by themselves not a secure environment. Even if the network itself is secure (for example by using IPSec [IPSEC]), 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. It is recommended that the implementers consider the security features as provided by the SNMPv3 framework. Specifically, the use of the User-based Security Model [SNMPv3USM] and the View-based Access Control [SNMPv3VACM] is recommended. It is then a customer/user responsibility to ensure that the SNMP entity giving Nadeau, et al. [Page 82] draft-nadeau-ccamp-gmpls-te-mib-00.txt November 2001 access to an instance of this MIB 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.
