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]. + + + + + + + +Dubuc, et al. Standards Track [Page 2] + +RFC 4220 MPLS TE Link MIB Module November 2005 + + +2. Introduction + + OSPF [RFC3630], Generalized MPLS (GMPLS) [RFC3471], and the Link + Management Protocol (LMP) [RFC4204] use the concept of traffic + engineering (TE) links to abstract link properties. The effect of + this approach is a reduction in the amount of routing information + exchanged in the network, which improves routing scalability. In + addition, the use of TE links allows the implementation of new + capabilities such as link protection. + + In this document, we present a MIB module that can be used to manage + TE links and their extension, the bundled link. This MIB module + enables both the configuration and the performance monitoring of TE + links and the bundled link. + + 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 [RFC2119]. + +3. Terminology + + This document uses terminology from the documents describing link + bundling [RFC4201] and GMPLS [RFC3945]. + + The link bundling feature is designed to aggregate one or more + similar entities between a node pair into a bundled link [RFC4201]. + In RFC 4201, those entities are referred to as TE links. A TE link + is a subinterface capable of carrying MPLS traffic engineered + traffic. A TE Link may be comprised of only one underlying component + link. In cases where more than one component links are to be + combined, multiple component links should be created with differing + priorities to indicate hot-standby or parallel utilization. + + A bundled link is another kind of Traffic Engineering (TE) link (see + [RFC4203]). A link bundle is a subinterface that binds the traffic + of a group of one or more TE links. There should be more than one TE + Link in a link bundle, but this is not a requirement. Furthermore, + if there are more than one TE links in a link bundle at some time, + and at some point later, all but one of the links are deleted, the + agent may choose to either delete the link bundle, or it may choose + to leave it intact. Traffic counters on a link bundle are cumulative + for all subinterfaces that it binds together. + + + + + + + + + +Dubuc, et al. Standards Track [Page 3] + +RFC 4220 MPLS TE Link MIB Module November 2005 + + +4. Feature Checklist + + The TE Link MIB module (TE-LINK-STD-MIB) is designed to satisfy the + following requirements and constraints: + + - The MIB module supports the management of TE links, including + bundled links. + + - Support is provided for configuration of traffic engineering + parameters associated with TE links. + + - The MIB module is used to monitor the priority-based component + link and TE link bandwidth values. + +5. Outline + + Configuring bundled links involves the following steps: + + - Creating a bundled link. + + - Creating TE links. + + - Optionally specifying the shared risk link groups associated with + the TE links. + + - Configuring the component links including the bandwidth parameters + and associating the component links with the appropriate TE link. + + - Associating the TE links with the appropriate bundled link. + +6. Brief Description of MIB Objects + + Sections 6.1 - 6.4 describe objects pertaining to TE links while + Sections 6.5 - 6.7 describe objects pertaining to component links. + The MIB objects were derived from the link bundling document + [RFC4201]. + +6.1. teLinkTable + + This table represents the TE links, including bundled links, and + their generic traffic engineering parameters. + +6.2. teLinkDescriptorTable + + This table represents the TE link interface switching capability + descriptors. + + + + + +Dubuc, et al. Standards Track [Page 4] + +RFC 4220 MPLS TE Link MIB Module November 2005 + + +6.3. teLinkSrlgTable + + This table represents the shared risk link groups (SRLGs) associated + with TE links. + +6.4. teLinkBandwidthTable + + This table specifies the priority-based bandwidth traffic engineering + parameters associated with TE links. + +6.5. componentLinkTable + + This table enumerates the component links and their generic traffic + engineering parameters. + +6.6. componentLinkDescriptorTable + + This table enumerates the interface switching capability descriptors + that each component link supports. + +6.7. componentLinkBandwidthTable + + The component link bandwidth table specifies the priority-based + bandwidth values associated with the component links. + + Component links that belong to the same TE link must be compatible. + If these two tables are managed independently, mechanisms should be + put in place to ensure consistency between the two tables. TE links + that form a bundled link must have compatible traffic engineering + parameters (resource class, link metric, and protection type). + + The link descriptors of the teLinkDescriptorTable can be derived from + the link descriptors of the componentLinkDescrTable. + + Some of the bandwidth parameters of the teLinkTable, + teLinkDescriptorTable, teLinkBandwidthTable are derived from the + bandwidth parameters of the componentLinkTable, + componentLinkDescriptorTable, and componentLinkBandwidthTable + (maximum reservable bandwidth, minimum LSP bandwidth, maximum LSP + bandwidth at specified priority, and unreserved bandwidth). + +7. Example of Bundled Link Setup + + In this section, we provide a brief example of using the MIB objects + described in section 10 to set up a bundled link. While this example + is not meant to illustrate every nuance of the MIB module, it is + intended as an aid to understanding some of the key concepts. It is + meant to be read after going through the MIB module itself. Section + + + +Dubuc, et al. Standards Track [Page 5] + +RFC 4220 MPLS TE Link MIB Module November 2005 + + + 8.2 provides more details on the use of the ifStackTable to establish + relationships between bundled links, TE links, and component links. + + Suppose that one would like to manually create a bundled link out of + two 1:1 TE links, as depicted in the figure in Section 8.2. Assume + that the bundled link is associated with SRLGs 10 and 50. Finally, + let the component links be port entity interfaces (lambdas). The + following example illustrates which rows and corresponding objects + might be created to accomplish this. + + First, a bundled link entry is created. An ifEntry with the same + ifIndex and with ifType teLink needs to be created beforehand. + + In teLinkTable: + { + ifIndex = 2, + teLinkAddressType = unknown(0), + teLinkLocalIpAddr = ''H, + teLinkRemoteIpAddr = ''H, + teLinkMetric = 5, + teLinkProtectionType = dedicated1For1(4), + teLinkWorkingPriority = 7, + teLinkResourceClass = 3, + teLinkIncomingIfId = 0, + teLinkOutgoingIfId = 2, + teLinkRowStatus = createAndGo(4), + teLinkStorageType = nonVolatile(3) + } + + In ifStackTable: + { + ifStackHigherLayer = 0, + ifStackLowerLayer = 2, + ifStackStatus = createAndGo(4) + } + + Next, the two TE links are created. + + In teLinkTable: + { + ifIndex = 3, + teLinkAddressType = unknown(0), + teLinkLocalIpAddr = ''H, + teLinkRemoteIpAddr = ''H, + teLinkMetric = 5, + teLinkProtectionType = unprotected(2), + teLinkWorkingPriority = 7, + teLinkResourceClass = 3, + + + +Dubuc, et al. Standards Track [Page 6] + +RFC 4220 MPLS TE Link MIB Module November 2005 + + + teLinkIncomingIfId = 0, + teLinkOutgoingIfId = 3, + teLinkRowStatus = createAndGo(4), + teLinkStorageType = nonVolatile(3) + } + + In ifStackTable: + { + ifStackHigherLayer = 2, + ifStackLowerLayer = 3, + ifStackStatus = createAndGo(4) + } + + In teLinkTable: + { + ifIndex = 4, + teLinkAddressType = unknown(0), + teLinkLocalIpAddr = ''H, + teLinkRemoteIpAddr = ''H, + teLinkMetric = 5, + teLinkProtectionType = unprotected(2), + teLinkWorkingPriority = 7, + teLinkResourceClass = 3, + teLinkIncomingIfId = 0, + teLinkOutgoingIfId = 4, + teLinkRowStatus = createAndGo(4), + teLinkStorageType = nonVolatile(3) + } + + In ifStackTable: + { + ifStackHigherLayer = 2, + ifStackLowerLayer = 4, + ifStackStatus = createAndGo(4) + } + + We assign SRLGs to the TE links. + + In the teLinkSrlgTable: + { + ifIndex = 3, + teLinkSrlg = 10, + teLinkSrlgRowStatus = createAndGo(4), + teLinkSrlgStorageType = nonVolatile(3) + } + + In the teLinkSrlgTable: + { + + + +Dubuc, et al. Standards Track [Page 7] + +RFC 4220 MPLS TE Link MIB Module November 2005 + + + ifIndex = 4, + teLinkSrlg = 50, + teLinkSrlgRowStatus = createAndGo(4), + teLinkSrlgStorageType = nonVolatile(3) + } + + The bundled link inherits the SRLG properties from the associated TE + links. + + Next, for each unbundled TE link, a component link is created. An + ifEntry with the same ifIndex needs to be created beforehand. + + In componentLinkTable: + { + ifIndex = 5, + componentLinkPreferredProtection = primary(1), + componentLinkRowStatus = createAndGo(4), + componentLinkStorageType = nonVolatile(3) + } + + In ifStackTable: + { + ifStackHigherLayer = 3, + ifStackLowerLayer = 5, + ifStackStatus = createAndGo(4) + } + + In componentLinkTable: + { + ifIndex = 6, + componentLinkPreferredProtection = secondary(2), + componentLinkRowStatus = createAndGo(4) + componentLinkStorageType = nonVolatile(3) + } + + In ifStackTable: + { + ifStackHigherLayer = 4, + ifStackLowerLayer = 6, + ifStackStatus = createAndGo(4) + } + + In this example, once a component link is added to the + componentLinkTable, the associated link descriptors are implicitly + added to the componentLinkDescriptorTable. + + TE link link descriptors are derived from their component link + descriptors. + + + +Dubuc, et al. Standards Track [Page 8] + +RFC 4220 MPLS TE Link MIB Module November 2005 + + + Note that the bandwidth attributes in teLinkDescriptorTable, + componentLinkDescriptorTable, teLinkBandwidthTable, and + componentLinkBandwidthTable are maintained by the device according to + LSP creation/deletion at different priorities. The values in the + teLinkBandwidthTable are an aggregation of the values for the + component links of the TE links and the TE links of the bundled link. + +8. Application of the Interfaces Group to TE Links + + The Interfaces Group [RFC2863] defines generic managed objects for + managing interfaces. This memo contains the media-specific + extensions to the Interfaces Group for managing TE Link interfaces as + logical interfaces. + + This memo assumes the interpretation of the Interfaces Group to be in + accordance with [RFC2863], 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 TE Link interface is + represented as an entry in the ifTable. The interrelation of entries + in the ifTable is defined by Interfaces Stack Group, as defined in + [RFC2863]. + + When using TE Link interfaces, the interface stack table might appear + as follows: + + +----------------------------------------+ + | TE link-interface ifType = teLink(200) + + +----------------------------------------+ + | Underlying Layer... + + +----------------------------------------+ + + In the above diagram, "Underlying Layer..." refers to the ifIndex of + any interface type, which has been defined for TE Link interworking. + Examples include ATM, Frame Relay, Ethernet, etc. + +8.1. Support of the TE Link Layer by ifTable + + Some specific interpretations of ifTable for the TE Link layer + follow. + + Object Use for the TE Link layer + + ifIndex Each TE Link interface is represented by an ifEntry. + + ifDescr Description of the TE Link interface. + + + + + +Dubuc, et al. Standards Track [Page 9] + +RFC 4220 MPLS TE Link MIB Module November 2005 + + + ifType The value that is allocated for TE Link is 200 + [IANAifType]. + + ifSpeed The total bandwidth in bits per second for use by the + TE Link layer. + + ifPhysAddress Unused. + + ifAdminStatus This variable indicates the administrator's intent as + to whether TE Link should be enabled, disabled, or + running in some diagnostic testing mode on this + interface. Also see [RFC2863]. + + ifOperStatus This value reflects the actual or operational status of + the TE Link on this interface. + + ifLastChange See [RFC2863]. + + ifInOctets The number of received octets over the interface, i.e., + the number of received octets in all component links + associated with the interface. + + ifOutOctets The number of transmitted octets over the interface, + i.e., the number of octets transmitted over all + component links associated with the interface. + + ifInErrors The number of packets dropped due to uncorrectable + errors. + + ifInUnknownProtos + The number of received packets discarded during packet + header validation. + + ifOutErrors See [RFC2863]. + + ifName Textual name (unique on this system) of the interface, + or an octet string of zero length. + + ifLinkUpDownTrapEnable + Default is disabled (2). + + ifConnectorPresent + Set to false (2). + + ifHighSpeed See [RFC2863]. + + + + + + +Dubuc, et al.

For other encoding types, traffic + counters on a TE link are cumulative for all subinterfaces that it + binds together. + +8.2. Using ifStackTable + + This section describes, by example, how to use the ifStackTable to + represent the relationship of TE links with underlying TE-enabled + interfaces. Implementors of the stack table for TE link interfaces + should look at the appropriate RFC for the service being stacked on + TE links. The examples given below are for illustration purposes + only. + + Example: MPLS is being carried on a bundled TE link. The bundled + TE link represents a 1:1 optical transport interface. + + In this example, the component link is a TE link. The two component + links/TE links are grouped in a bundled link. + + +-------------------------------------------------------------------+ + | MPLS interface ifType = mpls(166) | + | ifIndex = 1 | + +-------------------------------------------------------------------+ + | TE link (bundled link) ifType = teLink(200) | + | ifIndex = 2 | + +--------------------------------+-+--------------------------------+ + | TE link ifType = teLink(200) | | TE link ifType = teLink(200) | + | ifIndex = 3 | | ifIndex = 4 | + +--------------------------------+ +--------------------------------+ + | Component link | | Component link | + | ifType = opticalTransport(196) | | ifType = opticalTransport(196) | + | ifIndex = 5 | | ifIndex = 6 | + +--------------------------------+ +--------------------------------+ + + + + +Dubuc, et al.

Security Considerations + + 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: + + - All the tables in this MIB module have routing information in + them, so they all have the same security attributes. Unauthorized + changes to attributes of these tables can disrupt resource + allocation in the network. + + 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: + + - IP address entries in the teLinkTable (teLinkLocalIpAddr and + teLinkRemoteIpAddr) may reveal the internals of a network provider + IP address space. + + 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. + + + + + + +Dubuc, et al.
