1. Abstract
This memo defines an experimental portion of the Management Informa-
tion Base (MIB) for use with network management protocols in the
Internet community. In particular, it describes managed objects for
modeling link bundling as described in [BUNDLING].
2. Introduction
This memo defines an experimental portion of the Management Informa-
tion Base (MIB) for use with network management protocols in the
Internet community. In particular, it describes managed objects for
modeling link bundling as described in [BUNDLING].
Comments should be made directly to the MPLS mailing list at
mpls@uu.net.
This memo does not, in its draft form, specify a standard for the
Internet community.
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
Dubuc et al. Expires November 2001 [Page 2]
Internet Draft MPLS Link Bundling MIB May 22, 2001
[BCP14].
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
traffic. A TE Link may be comprised of only one underlying data-
bearing channels. In cases where more than one data-bearing channel
is to be combined, multiple data-bearing links should be created with
differing priorities 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 bonds 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. Furth-
ermore, 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. The SNMP Management Framework
The SNMP Management Framework presently consists of five major com-
ponents:
- An overall architecture, described in RFC 2571 [SNMPArch].
- 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
RFC 1155 [SMIv1], RFC 1212 [SNMPv1MIBDef] and RFC 1215
[SNMPv1Traps]. The second version, called SMIv2, is described
in RFC 2578 [SMIv2], RFC 2579 [SNMPv2TC] and RFC 2580
[SNMPv2Conf].
- Message protocols for transferring management information. The
first version of the SNMP message protocol is called SNMPv1
and described in RFC 1157 [SNMPv1]. A second version of the
Dubuc et al. Expires November 2001 [Page 3]
Internet Draft MPLS Link Bundling MIB May 22, 2001
SNMP message protocol, which is not an Internet standards
track protocol, is called SNMPv2c and described in RFC 1901
[SNMPv2c] and RFC 1906 [SNMPv2TM]. The third version of the
message protocol is called SNMPv3 and described in RFC 1906
[SNMPv2TM], RFC 2272 [SNMPv3MP] and RFC 2574 [SNMPv3USM].
- Protocol operations for accessing management information. The
first set of protocol operations and associated PDU formats is
described in RFC 1157 [SNMPv1]. A second set of protocol
operations and associated PDU formats is described in RFC 1905
[SNMPv2PO].
- A set of fundamental applications described in RFC 2273
[SNMPv3App] and the view-based access control mechanism
described in RFC 2575 [SNMPv3VACM].
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 possi-
ble (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 informa-
tion is not considered to change the semantics of the MIB.
4.1. Object Definitions
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined using the subset of Abstract Syntax Notation One (ASN.1)
defined in the SMI. In particular, each object type is named by an
OBJECT IDENTIFIER, an administratively assigned name. The object
type together with an object instance serves to uniquely identify a
specific instantiation of the object. For human convenience, we often
use a textual string, termed the descriptor, to also refer to the
object type.
5. Feature Checklist
The link bundling MIB (LINK-BUNDLING-MIB) is designed to satisfy the
following requirements and constraints:
Dubuc et al. Expires November 2001 [Page 4]
Internet Draft MPLS Link Bundling MIB May 22, 2001
- The MIB supports the management of TE links, including bundled
links.
- Support is provided for configuration of traffic engineering
parameters associated with TE links.
- The MIB is used to monitor the priority-based data-bearing channel
and TE link bandwidth values.
6. 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 data-bearing channels including the bandwidth
parameters and associating the data-bearing channels with the
appropriate TE link.
- Associating the TE links with the appropriate bundled link.
6.1. Summary of Link Bundling MIB
The MIB objects for performing these actions consist of the following
tables:
- The TE link table (teLinkTable), which is used to
specify TE links, including bundled links, and their generic
traffic engineering parameters.
- The TE link descriptor table (teLinkDescriptorTable), which is
used to enumerate the TE link descriptors.
- The TE link OSPF traffic engineering table
(teLinkOspfTeTable), which is used for configuring OSPF
traffic engineering parameters associated with TE links.
- The shared risk link group (SRLG) table (teLinkSrlgTable),
which is used to specify the SRLGs associated with TE links.
Dubuc et al. Expires November 2001 [Page 5]
Internet Draft MPLS Link Bundling MIB May 22, 2001
- The TE link bandwidth table (teLinkBandwidthTable),
which is used for reporting priority-based bandwidth values
associated with TE links.
- The data-bearing channel table (dataBearingChannelTable), which is
used to identify the data-bearing channels that are associated
with the TE links and specify the data-bearing channel generic
traffic engineering parameters.
- The data-bearing channel link descriptor table
(dataBearingChannelDescriptorTable), which is used to enumerate
the data-bearing channel link descriptors.
- The data-bearing channel bandwidth table
(dataBearingChannelBandwidthTable), which is used to report
priority-based bandwidth values associated with data-bearing
channels.
These tables are described in the subsequent sections.

8. Example of Bundled Link Setup
In this section we provide a brief example of using the MIB
objects described in section 9 to set up a bundled link.
While this example is not meant to illustrate every
nuance 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.
Suppose that one would like to manually create a bundled link
out of two 1:1 TE links. Assume that the bundled link is associated
with SRLGs 10 and 50. Finally, let the data-bearing channels be port
entity interfaces (lambdas). The following example illustrates which
Dubuc et al. Expires November 2001 [Page 7]
Internet Draft MPLS Link Bundling MIB May 22, 2001
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 = 25,
teLinkNumberingType = unnumbered(1),
teLinkRowStatus = createAndGo(4)
}
In ifStackTable:
{
ifStackHigherLayer = 0,
ifStackLowerLayer = 25,
ifStackStatus = createAndGo(4)
}
Next, the two TE links are created.
In teLinkTable:
{
ifIndex = 20,
teLinkNumberingType = unnumbered(1),
teLinkMetric = 5,
teLinkResourceClass = 3,
teLinkRowStatus = createAndWait(5)
}
In ifStackTable:
{
ifStackHigherLayer = 25,
ifStackLowerLayer = 20,
ifStackStatus = createAndGo(4)
}
In teLinkTable:
{
ifIndex = 21,
teLinkNumberingType = unnumbered(1),
teLinkMetric = 5,
teLinkResourceClass = 3,
teLinkRowStatus = createAndWait(5)
}
In ifStackTable:
{
Dubuc et al. Expires November 2001 [Page 8]
Internet Draft MPLS Link Bundling MIB May 22, 2001
ifStackHigherLayer = 25,
ifStackLowerLayer = 21,
ifStackStatus = createAndGo(4)
}
The OSPF traffic engineering parameters are configured for the
TE links.
In teLinkOspfTeTable:
{
ifIndex = 20,
teLinkOspfLinkId = 'c0010101'H, -- 192.1.1.1
teLinkRowStatus = createAndGo(4)
}
In teLinkOspfTeTable:
{
ifIndex = 21,
teLinkOspfLinkId = 'c0010101'H, -- 192.1.1.1
teLinkRowStatus = createAndGo(4)
}
We assign SRLGs to the TE links.
In the teLinkSrlgTable:
{
ifIndex = 20,
srlg = 10,
srlgRowStatus = createAndGo(4)
}
In the teLinkSrlgTable:
{
ifIndex = 21,
srlg = 50,
srlgRowStatus = createAndGo(4)
}
The bundled link inherits the OSPF and SRLG properties from the
associated TE links.
Next, for each TE link, two data-bearing channels are created.
An ifEntry with the same ifIndex needs to be created beforehand.
In dataBearingChannelTable:
{
ifIndex = 40,
dataBearingChannelPreferredProtection = primary(1),
Dubuc et al. Expires November 2001 [Page 9]
Internet Draft MPLS Link Bundling MIB May 22, 2001
dataBearingChannelRowStatus = createAndGo(4)
}
In ifStackTable:
{
ifStackHigherLayer = 20,
ifStackLowerLayer = 40,
ifStackStatus = createAndGo(4)
}
In dataBearingChannelTable:
{
ifIndex = 43,
dataBearingChannelPreferredProtection = secondary(2),
dataBearingChannelRowStatus = createAndGo(4)
}
In ifStackTable:
{
ifStackHigherLayer = 20,
ifStackLowerLayer = 43,
ifStackStatus = createAndGo(4)
}
In dataBearingChannelTable:
{
ifIndex = 44,
dataBearingChannelPreferredProtection = primary(1),
dataBearingChannelRowStatus = createAndGo(4)
}
In ifStackTable:
{
ifStackHigherLayer = 21,
ifStackLowerLayer = 44,
ifStackStatus = createAndGo(4)
}
In dataBearingChannelTable:
{
ifIndex = 48,
dataBearingChannelPreferredProtection = secondary(2),
dataBearingChannelRowStatus = createAndGo(4)
}
In ifStackTable:
{
ifStackHigherLayer = 21,
Dubuc et al. Expires November 2001 [Page 10]
Internet Draft MPLS Link Bundling MIB May 22, 2001
ifStackLowerLayer = 48,
ifStackStatus = createAndGo(4)
}
In this example, once a data-bearing channel is added to the
dataBearingChannelTable, the associated link descriptors are
implicitly added to the dataBearingChannelDescriptorTable.
TE link link descriptors are derived from their data-bearing channel
link descriptors.
Note that the bandwidth attributes in teLinkDescriptorTable,
dataBearingChannelDescriptorTable, teLinkBandwidthTable
and dataBearingChannelBandwidthTable 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 data-bearing channels of the TE links and
the TE links of the bundled link.
9. Application of the Interface Group to TE Links
The Interfaces Group of MIB II defines generic managed objects for
managing interfaces. This memo contains the media-specific
extensions to the Interfaces Group for managing TE LInk interfaces.
This memo assumes the interpretation of the Interfaces Group to be
in accordance with [IFMIB] 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 [IFMIB].
When using TE Link interfaces, the interface stack table might appear
as follows:
+----------------------------------------+
| TE link-interface ifType = teLink(TBD) +
+----------------------------------------+
| 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.
Dubuc et al. Expires November 2001 [Page 11]
Internet Draft MPLS Link Bundling MIB May 22, 2001
9.1. 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 TBD.
This number will be assigned by the IANA.
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 [IFMIB].
ifOperStatus This value reflects the actual or operational
status of TE Link on this interface.
ifLastChange See [IFMIB].
ifInOctets The number of received octets over the interface,
i.e., the number of received octets in all data-bearing
channels associated with the interface.
ifOutOctets The number of transmitted octets over the
interface, i.e., the number of octets transmitted
over all data-bearing channels 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 [IFMIB].
ifName Textual name (unique on this system) of the
Dubuc et al. Expires November 2001 [Page 12]
Internet Draft MPLS Link Bundling MIB May 22, 2001
interface or an octet string of zero length.
ifLinkUpDownTrapEnable
Default is disabled (2).
ifConnectorPresent
Set to false (2).
ifHighSpeed See [IFMIB].
ifHCInOctets The 64-bit version of ifInOctets; supported if
required by the compliance statements in [IFMIB].
ifHCOutOctets The 64-bit version of ifOutOctets; supported if
required by the compliance statements in [IFMIB].
ifAlias The non-volatile 'alias' name for the interface as
specified by a network manager.
ifCounterDiscontinuityTime
See [IFMIB].
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.
9.2. 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 2 bundled TE links.
Each bundled TE link runs over a 1:1 optical
transport interface.
+---------------------------------+
| mpls |
+---------------------------------+
|
+---------------------------------+
Dubuc et al. Expires November 2001 [Page 13]
Internet Draft MPLS Link Bundling MIB May 22, 2001
| teLink (Link Bundle) |
+---------------------------------+
| |
+---------------+ +---------------+
| teLink | | teLink |
+---------------+ +---------------+
| | | |
+------+ +------+ +------+ +------+
|oTrans| |oTrans| |oTrans| |oTrans|
+------+ +------+ +------+ +------+
The assignment of the index values could for example be:
ifIndex Description
1 mpls (type 166)
2 teLink (type TBD)
3 teLink (type TBD)
4 teLink (type TBD)
5 opticalTransport (type 196)
6 opticalTransport (type 196)
7 opticalTransport (type 196)
8 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
3 6
4 7
4 8
5 0
6 0
7 0
8 0
In the case where MPLS is using a single TE link, then
the upper TE link layer (link bundle) is not required.

The assignment of the index values could for example be:
ifIndex Description
1 mpls (type 166)
2 teLink (type TBD)
3 opticalTransport (type 196)
4 opticalTransport (type 196)
The ifStackTable is then used to show the relationships between the
various interfaces.

11. Security Considerations
It is clear that this MIB is potentially useful for monitoring of
link bundling enabled devices. This MIB can also be used for confi-
guration of certain objects, and anything that can be configured can
be incorrectly configured, with potentially disastrous results.
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 opera-
tor error, which is beyond the scope of any security architecture.
There are a number of management objects defined in this MIB which
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 environ-
ment without proper protection can have a negative effect on network
operations. The use of SNMP Version 3 is recommended over prior ver-
sions, for configuration control, as its security model is improved.
SNMPv1 or SNMPv2 are by themselves not a secure environment. Even if
Dubuc et al. Expires November 2001 [Page 43]
Internet Draft MPLS Link Bundling MIB May 22, 2001
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
access to an instance of this MIB is properly configured to give
access to the objects only to those principals (users) that have leg-
itimate rights to indeed GET or SET (change/create/delete) them.
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 OSPF/MPLS network.
Allowing uncontrolled access to these objects could result in mali-
cious and unwanted disruptions of network traffic or incorrect confi-
gurations for these customers. There are no objects that are particu-
larly sensitive in their own right, such as passwords or monetary
amounts.
