1. 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].
2. Introduction
OSPF [OSPF], Generalized MPLS (GMPLS) [RFC3471] and the Link Manage-
ment Protocol (LMP) [LMP] use the concept of traffic engineering (TE)
links to abstract link properties. The effect of this approach is the
reduction of the amount of routing information exchanged in the
Dubuc et al. Expires November 2003 [Page 2]
Internet Draft MPLS TE Link MIB Module August 26, 2003
network, which improves routing scalability. In addition, the use of
TE link allows the implementation of new capabilities such as link
protection.
We present in this document 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 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, reference
[RFC2119].
3. Terminology
This document uses terminology from the documents describing link
bundling [BUNDLING] and G-MPLS [GMPLS-ARCH].
The link bundling feature is designed to aggregate one or more simi-
lar entities between a node pair into a bundled link [BUNDLING]. In
the document, those entities are referred to as TE links. A TE link
is a subinterface capable of carrying MPLS traffic engineered traf-
fic. A TE Link may be comprised of only one underlying component
link. In cases where more than one component links are to be com-
bined, multiple component links should be created with differing pri-
orities to indicate hot-standby or parallel utilization.
A bundled link is just another kind of Traffic Engineering (TE) link
(see [GMPLS-OSPF]). A link bundle is a subinterface which bounds 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. Fur-
thermore, if there are more than one TE link 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 which it binds together.
4. Feature Checklist
The TE Link MIB module (TE-LINK-MIB) is designed to satisfy the fol-
lowing 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.
Dubuc et al. Expires November 2003 [Page 3]
Internet Draft MPLS TE Link MIB Module August 26, 2003
- 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. The MIB
objects were derived from the link bundling document [BUNDLING].
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.
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.
Dubuc et al. Expires November 2003 [Page 4]
Internet Draft MPLS TE Link MIB Module August 26, 2003
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 band-
width 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, teLinkDescrip-
torTable, teLinkBandwidthTable are derived from the bandwidth parame-
ters of the componentLinkTable, componentLinkDescriptorTable and com-
ponentLinkBandwidthTable (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. More details on the use of the ifStackTable
to establish relationship between bundled links, TE links and
component links are given in Section 8.2.
Suppose that one would like to manually create a bundled link
out of two 1:1 TE links as depicted on 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.
Dubuc et al. Expires November 2003 [Page 5]
Internet Draft MPLS TE Link MIB Module August 26, 2003
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,
teLinkIncomingIfId = 0,
teLinkOutgoingIfId = 3,
teLinkRowStatus = createAndGo(4),
teLinkStorageType = nonVolatile(3)
}
In ifStackTable:
{
ifStackHigherLayer = 2,
ifStackLowerLayer = 3,
Dubuc et al. Expires November 2003 [Page 6]
Internet Draft MPLS TE Link MIB Module August 26, 2003
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:
{
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.
Dubuc et al. Expires November 2003 [Page 7]
Internet Draft MPLS TE Link MIB Module August 26, 2003
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.
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 inter-
relation of entries in the ifTable is defined by Interfaces Stack
Group 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.
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.
Dubuc et al. Expires November 2003 [Page 9]
Internet Draft MPLS TE Link MIB Module August 26, 2003
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 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].
ifHCInOctets The 64-bit version of ifInOctets; supported if
required by the compliance statements in [RFC2863].
ifHCOutOctets The 64-bit version of ifOutOctets; supported if
required by the compliance statements in [RFC2863].
ifAlias The non-volatile 'alias' name for the interface as
specified by a network manager.
Dubuc et al. Expires November 2003 [Page 10]
Internet Draft MPLS TE Link MIB Module August 26, 2003
ifCounterDiscontinuityTime
See [RFC2863].
Support for ifInOctets, ifOutOctets, ifInErrors, ifInUnknownProtos,
ifOutErrors, ifHCInOctets and ifHCOutOctets objects is not required
if encoding type is clear. For other encoding types, traffic
counters on a TE link are cumulative for all subinterfaces which it
binds together.
8.2. Using ifStackTable
This section describes by example how to use 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. Examples given below are for illustration purposes
only.
Example: MPLS is being carried on a bundled TE links.
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 |
+--------------------------------+ +--------------------------------+
The assignment of the index values could for example be:
ifIndex Description
1 mpls (type 166)
2 teLink (type 200)
3 teLink (type 200)
4 teLink (type 200)
5 opticalTransport (type 196)
Dubuc et al. Expires November 2003 [Page 11]
Internet Draft MPLS TE Link MIB Module August 26, 2003
6 opticalTransport (type 196)
The ifStackTable is then used to show the relationships between the
various interfaces.
ifStackTable Entries
HigherLayer LowerLayer
0 1
1 2
2 3
2 4
3 5
4 6
5 0
6 0
In the case where MPLS is using a single TE link, then
the upper TE link layer (link bundle) is not required.
+-----------------------------------+
| MPLS interface ifType = mpls(166) |
+-----------------------------------+
| TE link ifType = teLink(200) |
+-----------------------------------+
| Component link |
| ifType = opticalTransport(196) |
+-----------------------------------+
The assignment of the index values could for example be:
ifIndex Description
1 mpls (type 166)
2 teLink (type 200)
3 opticalTransport (type 196)
The ifStackTable is then used to show the relationships between the
various interfaces.
ifStackTable Entries

document or the extent to which any license under such rights might
or might not be available; neither does it represent that it has made

procedures with respect to rights in standards-track and standards-
related documentation can be found in BCP-11. Copies of claims of
rights made available for publication and any assurances of licenses
to be made available, or the result of an attempt made to obtain a
general license or permission for the use of such proprietary rights
by implementers or users of this specification can be obtained from
the IETF Secretariat.
The IETF invites any interested party to bring to its attention any
copyrights, patents or patent applications, or other proprietary
rights which may cover technology that may be required to practice
this standard. Please address the information to the IETF Executive
Director.
11. 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
Dubuc et al. Expires November 2003 [Page 50]
Internet Draft MPLS TE Link MIB Module August 26, 2003
environments. The support for SET operations in a non-secure environ-
ment without proper protection can have a negative effect on network
operations. These are the tables and objects and their sensitiv-
ity/vulnerability:
- All the tables in this MIB module have routing information in
them and 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 con-
trol 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 sensi-
tivity/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), includ-
ing full support for the SNMPv3 cryptographic mechanisms (for authen-
tication and privacy).
Further, deployment of SNMP versions prior to SNMPv3 is NOT RECOM-
MENDED. 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.
