Internet-Draft IPFIX MIB March 2012
1. Introduction
This document defines two MIB modules for monitoring IP Flow
Information eXport (IPFIX) Devices including Exporters and
Collectors. While most of the objects defined by the IPFIX MIB
module must be implemented, some objects may be implemented
corresponding to the functionality implemented in the equipment.
Since the IPFIX architecture [RFC5470] foresees the possibility of
using Filtering and/or Sampling functions to reduce the data volume,
this document also provides the IPFIX SELECTOR MIB module, which
contains the standardized selection methods and is controlled by
IANA. The full configuration of the IPFIX Metering Process is out of
the scope of these MIB modules.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in RFC
2119 [RFC2119].

2. IPFIX Documents Overview
The IPFIX protocol provides network administrators with access to IP
Flow information. The architecture for the export of measured IP
Flow information out of an IPFIX Exporting Process to a Collecting
Process is defined in [RFC5470], per the requirements defined in
[RFC3917]. The protocol document [RFC5101] specifies how IPFIX Data
Records and Templates are carried via a congestion-aware transport
protocol from IPFIX Exporting Processes to IPFIX Collecting
Processes. IPFIX has a formal description of IPFIX Information
Elements, their name, type and additional semantic information, as
specified in [RFC5102]. Finally, [RFC5472] describes what type of
applications can use the IPFIX protocol and how they can use the
information provided. It furthermore shows how the IPFIX framework
relates to other architectures and frameworks.
It is assumed that Flow metering, export, and collection is performed
according to the IPFIX architecture defined in [RFC5470]. The
monitored configuration parameters of the export and collection of
Flow Templates and Data Records is modeled according to [RFC5101].
Packet selection methods that may be optionally used by the IPFIX
Metering Process are not considered in this MIB module. They are
defined in the Packet Sampling (PSAMP) framework [RFC5474] and
Sampling techniques [RFC5475] documents. Nevertheless, the basis for
defining Sampling and Filtering functions is given with the IPFIX
SELECTOR MIB module. Since the PSAMP export protocol [RFC5476] is
based on the IPFIX protocol, the Sampling and Filtering functions can
be added to the IPFIX SELECTOR MIB module as needed.

3. 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 MIB
modules that are 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. Terminology
The definitions of the basic terms like IP Traffic Flow, Exporting
Process, Collecting Process, Observation Points, etc. can be found in
the IPFIX protocol document [RFC5101].
Dietz, et al. draft-ietf-ipfix-rfc5815bis-03.txt [Page 6]
Internet-Draft IPFIX MIB March 2012
5. Structure of the IPFIX MIB
The IPFIX MIB module consists of seven main tables, the Transport
Session table, the Template table and the corresponding Template
Definition table, the Export table, the Metering Process table, the
Observation Point table, and the Selection Process table. Since the
IPFIX architecture [RFC5470] foresees the possibility of using
Filtering and/or Sampling functions to reduce the data volume, the
MIB module provides the basic objects for these functions with the
Selection Process table. The IPFIX SELECTOR MIB module defined in
the next section provides the standard Filtering and Sampling
functions that can be referenced in the ipfixSelectionProcessTable.
All remaining objects contain statistical values for the different
tables contained in the MIB module.
The following subsections describe all tables in the IPFIX MIB
module.
5.1. The Transport Session Table
The Transport Session is the basis of the MIB module. The Transport
Session table (ipfixTransportSessionTable) contains all Transport
Sessions between Exporter and Collector. The table specifies the
transport layer protocol of the Transport Session and, depending on
that protocol, further parameters for the Transport Session. In the
case of UDP and TCP, these are the source and destination address as
well as the source and destination port. For Stream Control
Transmission Protocol (SCTP), the table contains the SCTP Assoc Id,
which is the index for the SCTP association in the SCTP MIB module
[RFC3873]. The mode of operation of the device, i.e., if the
Transport Session is used for collecting or exporting is given in the
ipfixTransportSessionDeviceMode object. Further on, it contains the
configured refresh parameters for Templates and Options Templates
that are used across unreliable connections as UDP. Finally, the
IPFIX version that is exported or collected by this Transport Session
and a status of the Transport Session is given in the table.
To illustrate the use of the above tables, let us assume the
following scenario: we have an Exporter on IP address 192.0.2.22 and
a Collector on IP address 192.0.2.37. The Exporter uses TCP to
export Templates and Data Records. The same Exporter also exports,
with UDP, to a Collector with the IP address of 192.0.2.44. This
would lead to the following Transport Session table on the Exporter:

The values in brackets are the OID numbers. The Collectors would
then have the same entry except that the index would most likely
differ and the ipfixTransportSessionDeviceMode would be
collecting(2).
Dietz, et al. draft-ietf-ipfix-rfc5815bis-03.txt [Page 8]
Internet-Draft IPFIX MIB March 2012
5.2. The Template Table
The Template table lists all Templates (including Options Templates)
that are sent (by an Exporter) or received (by a Collector). The
(Options) Templates are unique per Observation Domain and per
Transport Session. Note that the Transport Session also gives the
device mode, i.e. Exporter or Collector. Thus, the table is indexed
by:
o the Transport Session Index (ipfixTransportSessionIndex)
o and the Observation Domain Id (ipfixTemplateObservationDomainId).
It contains the Set Id and an access time denoting the time when the
(Options) Template was last sent or received.
To resume the above example, the Exporter may want to export a
Template and an Options Template for each Transport Session defined
above. This leads to the following Template table defining Template
and Options Template:

| +- ipfixTemplateObservationDomainId (1) = 3
| +- ipfixTemplateId (2) = 273
| +- ipfixTemplateSetId (3) = 2
| +- ipfixTemplateAccessTime (4)
| = 2008-7-1,12:49:11.2,+2:0
|

+- ipfixTemplateObservationDomainId (1) = 3
+- ipfixTemplateId (2) = 289
+- ipfixTemplateSetId (3) = 3
+- ipfixTemplateAccessTime (4)
= 2008-7-1,12:47:04.8,+2:0
We assume that the Transport Session that is stored with index 5 in
the Transport Session table of the Exporter is stored with index 17
in the Transport Session table of the (corresponding) Collector.
Then, the Template table would look as follows:
Dietz, et al. draft-ietf-ipfix-rfc5815bis-03.txt [Page 10]
Internet-Draft IPFIX MIB March 2012
ipfixTemplateTable (3)
|
+- ipfixTemplateEntry (1)
|
+- index (17) (ipfixTransportSessionIndex)
+- index (3) (ipfixTemplateObservationDomainId)
+ index (257) (ipfixTemplateId)
| +- ipfixTemplateObservationDomainId (1) = 3
| +- ipfixTemplateId (2) = 257
| +- ipfixTemplateSetId (3) = 2
| +- ipfixTemplateAccessTime (4)
| = 2008-7-1,12:49:11.8,+2:0
|
+ index (264) (ipfixTemplateId)
+- ipfixTemplateObservationDomainId (1) = 3
+- ipfixTemplateId (2) = 264
+- ipfixTemplateSetId (3) = 3
+- ipfixTemplateAccessTime (4)
= 2008-7-1,12:47:05.3,+2:0
The table on the second Collector would be analogous to the one shown
above.
5.3. The Template Definition Table
The Template Definition table lists all the Information Elements
contained in a Template or Options Template. Therefore, it has the
same indexes as the corresponding Template table plus the Template
Id. Its own index denotes the order of the Information Element
inside the Template. Besides the Information Element Id and the
length of the encoded value, the table contains the enterprise number
for enterprise-specific Information Elements and flags for each
Information Element. The flags indicate if the Information Element
is used for scoping or as a Flow Key.
To resume the above example again, the Exporter is configured to
export the octets received and dropped at the Observation Point since
the last export of these values. In addition, it exports the start
and end time of the Flow relative to the timestamp contained in the
IPFIX header. This leads to the following Template Definition table
on the Exporter:
Dietz, et al. draft-ietf-ipfix-rfc5815bis-03.txt [Page 11]
Internet-Draft IPFIX MIB March 2012
ipfixTemplateDefinitionTable (4)
|
+- ipfixTemplateDefinitionEntry (1)
|
+- index (5) (ipfixTransportSessionIndex)
+- index (3) (ipfixTemplateObservationDomainId)
+ index (257) (ipfixTemplateId)
+- index (1) (ipfixTemplateDefinitionIndex)
| +- ipfixTemplateDefinitionIndex (1) = 1
| +- ipfixTemplateDefinitionIeId (2) = 158
| | (flowStartDeltaMicroseconds)
| +- ipfixTemplateDefinitionIeLength (3) = 4
| +- ipfixTemplateDefinitionEnterprise (4) = 0
| +- ipfixTemplateDefinitionFlags (5) = 0
|
+- index (2) (ipfixTemplateDefinitionIndex)
| +- ipfixTemplateDefinitionIndex (1) = 2
| +- ipfixTemplateDefinitionIeId (2) = 159
| | (flowEndDeltaMicroseconds)
| +- ipfixTemplateDefinitionIeLength (3) = 4
| +- ipfixTemplateDefinitionEnterprise (4) = 0
| +- ipfixTemplateDefinitionFlags (5) = 0
|
+- index (3) (ipfixTemplateDefinitionIndex)
| +- ipfixTemplateDefinitionIndex (1) = 3
| +- ipfixTemplateDefinitionIeId (2) = 1
| | (octetDeltaCount)
| +- ipfixTemplateDefinitionIeLength (3) = 8
| +- ipfixTemplateDefinitionEnterprise (4) = 0
| +- ipfixTemplateDefinitionFlags (5) = 0
|
+- index (4) (ipfixTemplateDefinitionIndex)
+- ipfixTemplateDefinitionIndex (1) = 4
+- ipfixTemplateDefinitionIeId (2) = 132
| (droppedOctetDeltaCount)
+- ipfixTemplateDefinitionIeLength (3) = 8
+- ipfixTemplateDefinitionEnterprise (4) = 0
+- ipfixTemplateDefinitionFlags (5) = 0
The corresponding table entry on the Collector is the same except
that it would have another ipfixTransportSessionIndex, e.g., 17 as in
the previous example.
5.4. The Export Table
On Exporters, the Export table (ipfixExportTable) can be used to
support features like failover, load-balancing, duplicate export to
several Collectors, etc. The table has three indexes that link an
Dietz, et al. draft-ietf-ipfix-rfc5815bis-03.txt [Page 12]
Internet-Draft IPFIX MIB March 2012
entry with:
o the Metering Process table (ipfixMeteringProcessCacheId, see
below)
o and the Transport Session table (ipfixTransportSessionIndex).
Those entries with the same ipfixExportIndex and the same
ipfixMeteringProcessCacheId define a Transport Session group. The
member type for each group member describes its functionality. All
Transport Sessions referenced in this table MUST have the
ipfixTransportSessionDeviceMode exporting(1).
If the Exporter does not use Transport Session grouping, then each
ipfixExportIndex contains a single ipfixMeteringProcessCacheId, and
thus a singe Transport Session (ipfixTransportSessionIndex) and this
session MUST have the member type primary(1).
For failover, a Transport Session group can contain one Transport
Session with member type "primary" and several Transport Sessions
with type secondary(2). Entries with other member types are not
allowed for that type of group. For load-balancing or parallel
export, all Transport Sessions in the group MUST have the same member
type, either loadBalancing(4) or parallel(3).
The algorithms used for failover or load-balancing are out of the
scope of this document.
To continue the example, we assume that the Exporter uses the two
connections shown in the examples above as one primary Transport
Session protected by a secondary Transport Session. The Exporter
then has the following entries in the ipfixExportTable:
Dietz, et al. draft-ietf-ipfix-rfc5815bis-03.txt [Page 13]
Internet-Draft IPFIX MIB March 2012
ipfixExportTable (5)
|
+- ipfixExportEntry (1)
|
+- index (7) (ipfixExportIndex)
| +- index (9) (ipfixMeteringProcessCacheId)
| | +- index (5) (ipfixTransportSessionIndex)
| | +- ipfixExportIndex (1) = 7
| | +- ipfixExportMemberType (2) = 1 (primary)
| |
| +- index (11) (ipfixTransportSessionIndex)
| +- ipfixExportIndex (1) = 7
| +- ipfixExportMemberType (2) = 2 (secondary)
|
+- index (8) (ipfixExportIndex)
+- index (9) (ipfixMeteringProcessCacheId)
+- index (5) (ipfixTransportSessionIndex)
| +- ipfixExportIndex (1) = 8
| +- ipfixExportMemberType (2) = 2 (secondary)
+- index (11) (ipfixTransportSessionIndex)
+- ipfixExportIndex (1) = 8
+- ipfixExportMemberType (2) = 1 (primary)
The example shows that the Exporter uses the Metering Process Cache
9, explained below, to export IPFIX Data Records for the Transport
Sessions 5 and 11. The Templates 257 and 264 defined above are
exported within Transport Session 5 as primary, while the secondary
Transport Session is 11. The Templates 273 and 289 are exported
within Transport Session 11 as primary, while the secondary Transport
Session is 5.
Here are the steps required by a manager in order to understand what
is/are the backups (if any) for Template Records exported from a
specific Exporter to a specific Collector:
1. Lookup the Collector IP address in the
ipfixTransportSessionDestinationAddress object (in the
ipfixTransportSessionTable).
2. From the same row, double check the Exporter IP address in the
ipfixTransportSessionSourceAddress object.
3. From the same row, write down the ipfixTransportSessionIndex
value.
4. Use that ipfixTransportSessionIndex value in the
ipfixTemplateTable, and look up the pairs of
(ipfixTemplateObservationDomainId, ipfixTemplateId). For there,
Dietz, et al. draft-ietf-ipfix-rfc5815bis-03.txt [Page 14]
Internet-Draft IPFIX MIB March 2012
the manager deduces the Template Record(s) (ipfixTemplateId),
exported from the Observation Domain(s)
(ipfixTemplateObservationDomainId) on the tracked Exporter
(ipfixTransportSessionSourceAddress) to the tracked Collector
(ipfixTransportSessionDestinationAddress).
5. Reusing the same ipfixTransportSessionIndex in ipfixExportTable,
lookup the table for a value of ipfixExportMemberType equals to
"primary". Note that they could be multiple entries for which
the ipfixExportMemberType equals to "primary" in the
ipfixExportTable, so multiple iterations might be required until
the correct value of ipfixTransportSessionIndex is found.
6. From the same row, write down the ipfixExportIndex value.
7. In the ipfixExportTable, under the same three indexes values
(ipfixExportIndex, ipfixMeteringProcessCacheId, and
ipfixTransportSessionIndex), lookup the entries for which
ipfixExportMemberType is different than "primary". Write down
the associated ipfixTransportSessionIndex value.
8. From the ipfixTransportSessionTable, look up the Transport
Session details for this ipfixTransportSessionIndex value. For
example, the secondary Collector IP address and port
(ipfixTransportSessionDestinationAddress and
ipfixTransportSessionSourcePort).
5.5. The Metering Process Table
The Metering Process, as defined in [RFC5101], consists of a set of
functions. Maintaining the Flow Records is one of them. This
function is responsible for passing the Flow Records to the Exporting
Process and also for detecting Flow expiration. The Flow Records
that are maintained by the Metering Process can be grouped by the
Observation Points at which they are observed. The instance that
maintains such a group of Flow Records is a kind of cache. For this
reason, the Metering Process table (ipfixMeteringProcessTable) is
indexed by cache Ids (ipfixMeteringProcessCacheId). Each cache can
be maintained by a separate instance of the Metering Process. To
specify the Observation Point(s) where the Flow Records are gathered,
the ipfixMeteringProcessObservationPointGroupRef may contain an
ipfixObservationPointGroupId from the Observation Point table
(ipfixObservationPointTable) described in the next section. If an
Observation Point is not specified for the Flow Records, the
ipfixMeteringProcessObservationPointGroupRef MUST be zero(0). The
timeouts (ipfixMeteringProcessCacheActiveTimeout and
ipfixMeteringProcessCacheInactiveTimeout) specify when Flows are
expired.

+- ipfixMeteringProcessCacheInactiveTimeout (4) = 100
5.6. The Observation Point Table
The Observation Point table (ipfixObservationPointTable) groups
Observation Points with the ipfixObservationPointGroupId. Each entry
contains the Observation Domain Id in which the Observation Point is
located and a reference to the ENTITY MIB module [RFC4133] or the
Interface MIB module [RFC2863]. The objects in the ENTITY MIB module
referenced by ipfixObservationPointPhysicalEntity or Interface MIB
module referenced by ipfixObservationPointPhysicalInterface denote
the Observation Point. At least one reference for the objects
ipfixObservationPointPhysicalEntity or
ipfixObservationPointPhysicalInterface MUST exist for a valid
Observation Point entry. If a reference to the Observation Point is
given in both object ipfixObservationPointPhysicalEntity and
ipfixObservationPointPhysicalInterface, then both MUST point to the
same physical interface. However, if one of two references
(ipfixObservationPointPhysicalEntity or
ipfixObservationPointPhysicalInterface) can not be given, its
reference MUST be 0. In addition, a direction can be given to render
more specifically which Flow to monitor.

5.7. The Selection Process Table
This table supports the usage of Filtering and Sampling functions, as
described in [RFC5470]. It contains lists of functions per Metering
Process cache (ipfixMeteringProcessCacheId). The selection process
index ipfixSelectionProcessIndex forms groups of selection methods
that are applied to an observed packet stream. The selection process
selector index (ipfixSelectionProcessSelectorIndex) indicates the
order in which the functions are applied to the packets observed at
the Observation Points associated with the Metering Process cache.
The selection methods are applied in increasing order, i.e.,
selection methods with a lower ipfixSelectionProcessSelectorIndex are
applied first. The functions are referred by object identifiers
pointing to the function with its parameters. If the selection
method does not use parameters, then it MUST point to the root of the
function subtree (see also Section 6). If the function uses
parameters, then it MUST point to an entry in the parameter table of
the selection method. If no Filtering or Sampling function is used
for a Metering Process, then an entry for the Metering Process SHOULD
be created pointing to the Select All function (ipfixFuncSelectAll).
5.8. The Statistical Tables
For the ipfixTransportSessionTable, the ipfixTemplateTable, the
ipfixMeteringProcessTable, and the ipfixSelectionProcessTable
Dietz, et al. draft-ietf-ipfix-rfc5815bis-03.txt [Page 17]
Internet-Draft IPFIX MIB March 2012
statistical tables are defined that augment those tables. All the
statistical tables contain a discontinuity object that holds a
timestamp that denotes the time when a discontinuity event occurred
to notify the management system that the counters contained in those
tables might not be continuous anymore.
5.8.1. The Transport Session Statistical Table
The Transport Session Statistical table
(ipfixTransportSessionStatsTable) augments the
ipfixTransportSessionTable with statistical values. It contains the
rate (in bytes per second) with which it receives or sends out IPFIX
Messages, the number of bytes, packets, messages, Records, Templates
and Options Templates received or sent and the number of messages
that were discarded.
5.8.2. The Template Statistical Table
This table contains a statistical value for each Template. It
augments the Template table (ipfixTemplateTable) and specifies the
number of Data Records exported or collected for the Template.
5.8.3. The Metering Process Statistical Table
This table augments the Metering Process table
(ipfixMeteringProcessTable). It contains the statistical values for
the exported Data Records and the number of unused cache entries.
5.8.4. The Selection Process Statistical Table
This table augments the Selection Process table
(ipfixSelectionProcessTable) and introduces two generic statistical
values, the number of packets observed and the number of packets
dropped by the selection method.

6. Structure of the IPFIX SELECTOR MIB
The IPFIX SELECTOR MIB module defined in this section provides the
standard Filtering and Sampling functions that can be referenced in
the ipfixSelectionProcessTable. All standard Filtering and Sampling
functions MUST be registered in the subtree under object
ipfixSelectorFunctions (iso.org.dod.internet.mgmt.mib-
2.ipfixSelectorMIB, or as numbers 1.3.6.1.2.1.194). The toplevel
OIDs in the subtree under object ipfixSelectorFunctions MUST be
registered in a subregistry maintained by IANA at
http://www.iana.org/assignments/smi-numbers. The first entry in this
subtree is the Select All function (ipfixFuncSelectAll) defined in
this document as {ipfixSelectorFunctions 1}.
Further selector functions MUST be registered at IANA and are subject
to Expert Review [RFC5226], i.e., review by one of a group of experts
designated by an IETF Area Director. The group of experts MUST check
the requested MIB objects for completeness and accuracy of the
description. Requests for MIB objects that duplicate the
functionality of existing objects SHOULD be declined. The smallest
available OID SHOULD be assigned to a new MIB objects. The
specification of new MIB objects SHOULD follow the structure
specified in the Section Section 6.1 and MUST be published using a
well-established and persistent publication medium. The experts will
initially be drawn from the Working Group Chairs and document editors
of the IPFIX and PSAMP Working Groups.
6.1. The Selector Functions
The following figure shows what the MIB tree usually should look
like. It already contains the ipfixFuncSelectAll. The subtree in
ipfixFuncF2 gives the basic structure that all selection methods
SHOULD follow.
ipfixSelectorFunctions
|
+- ipfixFuncSelectAll
| |
| +- ipfixFuncSelectAllAvail (is the function available?)
|
+- ipfixFuncF2
| |
| +- ipfixFuncF2Avail (is the function F2 available?)
| |
| +- ipfixFuncF2Parameters (a table with parameters)
...
|
+- ipfixFuncFn...
Dietz, et al. draft-ietf-ipfix-rfc5815bis-03.txt [Page 19]
Internet-Draft IPFIX MIB March 2012
The selection method SHOULD be designed as a MIB subtree introduced
by an object with the name ipfixFunc appended by a function name.
The objects in this subtree SHOULD be prefixed by this name. If the
function is named Fx, then we would start a subtree with an OID named
ipfixFuncFx. This subtree should contain an object ipfixFuncFxAvail
that has the type TruthValue. If a selection method takes
parameters, the MIB should contain a table named
ipfixFuncFxParameters, which should contain all the parameters that
the selection method specifies. An entry in this table will be
referenced by the IPFIX MIB module if the selection method with the
parameters is used.
To illustrate the structure defined above, the following contains an
example of a function MyFunc that holds three integer parameters
Param1, Param2, and Param3. In the example, there are currently two
instances of the parameters set defined with indexes 1 and 4.
ipfixSelectorFunctions (1)
|
+- ipfixFuncMyFunc (?)
|
+- ipfixFuncMyFuncAvail (1) = true
+- ipfixFuncMyFuncParameters (2)
|
+- ipfixFuncMyFuncParametersEntry (1)
|
+- index (1) (ipfixFuncMyFuncParametersIndex)
| +- ipfixFuncMyFuncParam1 (1) = 47
| +- ipfixFuncMyFuncParam2 (2) = -128
| +- ipfixFuncMyFuncParam3 (3) = 19
|
+- index(4) (ipfixFuncMyFuncParametersIndex)
+- ipfixFuncMyFuncParam1 (1) = 19
+- ipfixFuncMyFuncParam2 (2) = -1
+- ipfixFuncMyFuncParam3 (3) = 728
If the function defined above is referenced in the IPFIX MIB module,
the ipfixSelectionProcessTable would look as follows:
Dietz, et al. draft-ietf-ipfix-rfc5815bis-03.txt [Page 20]
Internet-Draft IPFIX MIB March 2012
ipfixSelectionProcessTable (8)
|
+- ipfixSelectionProcessEntry (1)
|
+- index (9) (ipfixMeteringProcessCacheId)
+- index (1) (ipfixSelectionProcessIndex)
+- index (1) (ipfixSelectionProcessSelectorIndex)
| +- ipfixSelectionProcessSelectorFunction (3)
| = ipfixSelectorFunctions.?.2.1.4
+- index (2) (ipfixSelectionProcessSelectorIndex)
+- ipfixSelectionProcessSelectorFunction (3)
= ipfixSelectorFunctions.?.2.1.1
This means that for the ipfixMeteringProcessCacheId(9), a Selection
Process with index 1 is created that applies two times the same
function but with different parameter sets. First, the function
MyFunc is applied with the parameters of the set with index 4 and the
with the parameters of the set with index 1.

Internet-Draft IPFIX MIB March 2012
7. Relationship to Other MIB Modules
Besides the usual imports from the SNMP Standards [RFC2578],
[RFC2579], and [RFC2580], the IPFIX MIB module references the ENTITY
MIB module [RFC4133] and the Interface MIB module [RFC2863].
7.1. Relationship to the ENTITY MIB and Interface MIB
The Observation Point table (ipfixObservationPointTable) contains a
reference to the ENTITY MIB module [RFC4133]
(ipfixObservationPointPhysicalEntity) or the Interface MIB module
[RFC2863] (ipfixObservationPointPhysicalInterface). If the
implementors of the IPFIX MIB module want to specify the physical
entity where Flows are observed, then they SHOULD also implement the
ENTITY MIB and/or the Interface MIB module. The implementation of
the ENTITY MIB and/or Interface MIB module is OPTIONAL. If one of
them is not implemented, then all values of the respective column
ipfixObservationPointPhysicalEntity or
ipfixObservationPointPhysicalInterface in the Observation Point table
are zero and the values of the
ipfixObservationPointPhysicalEntityDirection columns are unknown(0),
if none of them are defined.
7.2. MIB Modules Required for IMPORTS
The IPFIX MIB module requires the modules SNMPv2-SMI [RFC2578],
SNMPv2-TC [RFC2579], and SNMPv2-CONF [RFC2580]. Further on, it
imports the textual conventions InetAddressType and InetAddress from
the INET ADDRESS MIB module [RFC4001].
The IPFIX SELECTOR MIB module also requires the modules SNMPv2-SMI
[RFC2578], SNMPv2-TC [RFC2579], and SNMPv2-CONF [RFC2580].

The following values are valid:
unknown(0)
This value MUST be used if the status of the group

This value is used for a group member that is used as

primary(1) but MUST have the value secondary(2).
This value MUST also be specified if the Exporter does
not support Transport Session grouping. In this case,
the group contains only one Transport Session.
secondary(2)
This value is used for a group member that is used as a
secondary target of an Exporter. The Exporter will use
one of the targets specified as secondary(2) within the
same Transport Session group when the primary target is
not reachable.
parallel(3)
This value is used for a group member that is used for
duplicate exporting, i.e., all group members identified
by the ipfixExportIndex are exporting the same Records
in parallel. This implies that all group members MUST
have the same membertype parallel(3).
loadBalancing(4)
This value is used for a group member that is used
as one target for load-balancing. This means that a

DESCRIPTION
"The IPFIX SELECTOR MIB module defined in this section
Dietz, et al. draft-ietf-ipfix-rfc5815bis-03.txt [Page 59]
Internet-Draft IPFIX MIB March 2012
provides the standard Filtering and Sampling functions that
can be referenced in the ipfixSelectionProcessTable. All
standard Filtering and Sampling functions MUST be registered
in the subtree under object ipfixSelectorFunctions
(1.3.6.1.2.1.194.1.1). The toplevel OIDs in the subtree
under object ipfixSelectorFunctions MUST be registered in a
subregistry maintained by IANA at
http://www.iana.org/assignments/smi-numbers.
New selector functions MUST be registered at IANA and are
subject to Expert Review RFC 5226, i.e., review by one of a
group of experts designated by an IETF Area Director. The
group of experts MUST check the requested MIB objects for
completeness and accuracy of the description. Requests for
MIB objects that duplicate the functionality of existing
objects SHOULD be declined. The smallest available OID
SHOULD be assigned to a new MIB objects. The specification
of new MIB objects SHOULD follow the structure specified in
RFC [ThisRFC] and MUST be published using a well-
established and persistent publication medium. The experts
will initially be drawn from the Working Group Chairs and
document editors of the IPFIX and PSAMP Working Groups.

9. Security Considerations
There are no management objects defined in this MIB module that have
a MAX-ACCESS clause of read-write and/or read-create. So, if these
MIB modules are implemented correctly, then there is no risk that an
intruder can alter or create any management objects of these MIB
modules via direct SNMP SET operations.
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 ipfixTransportSessionTable - contains configuration data that
might be sensitive because objects in this table may reveal
information about the network infrastructure
o ipfixExportTable - contains configuration data that might be
sensitive because object in this table may reveal information
about the network infrastructure as well
o ipfixMeteringProcessTable - contains configuration data that might
be sensitive because objects in this table may reveal information
about the IPFIX Device itself
o ipfixObservationPointTable - contains configuration data that
might be sensitive because objects in this table may reveal
information about the IPFIX Device itself and the network
infrastructure
o ipfixSelectorFunctions - currently contains no sensitive data but
might want to be secured anyway since it may contain sensitive
data in a future version
All other objects and tables contain no data that is considered
sensitive.
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
Dietz, et al. draft-ietf-ipfix-rfc5815bis-03.txt [Page 63]
Internet-Draft IPFIX MIB March 2012
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 these MIB modules 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 Considerations
The MIB module in this document uses the following IANA-assigned
OBJECT IDENTIFIER values recorded in the SMI Numbers registry:
Descriptor OBJECT IDENTIFIER value
---------- -----------------------
ipfixMIB { mib-2 193 }
ipfixSelectorMIB { mib-2 194 }
NOTE TO RFC EDITOR: substitute ThisRFC with the RFC number of this
document after assignment in the following section.
The IPFIX SELECTOR MIB registry as defined in [RFC5815] Section 10
will be removed by IANA as its use is discontinued with this
document.
IANA will create and maintain a subregistry at
http://www.iana.org/assignments/smi-numbers in which the toplevel
OIDs in the subtree under object ipfixSelectorFunctions MUST be
registered. The initial version of this subregistry should contain
the following content:
Sub-registry Name: IPFIX-SELECTOR-MIB Functions
Reference: [ThisRFC]
Registration Procedures: Expert Review [RFC5226]
Prefix:
mib-2.ipfixSelectorMIB.ipfixSelectorObjects.ipfixSelectorFunctions
(1.3.6.1.2.1.194.1.1)
Decimal Name Description Reference
------- ---- ----------- ---------
1 ipfixFuncSelectAll Select everything [ThisRFC]
Additions to this subregistry are subject to Expert Review [RFC5226],
i.e., review by one of a group of experts designated by an IETF Area
Director. The group of experts MUST check the requested MIB objects
for completeness and accuracy of the description. Requests for MIB
objects that duplicate the functionality of existing objects SHOULD
be declined. The smallest available OID SHOULD be assigned to new
MIB objects. The specification of new MIB objects SHOULD follow the
structure specified in Section 6 and MUST be published using a well-
established and persistent publication medium. The experts will
initially be drawn from the Working Group Chairs and document editors
of the IPFIX and PSAMP Working Groups.
