<span class="h2"><a class="selflink" id="section-1" href="#section-1">1</a>. Introduction</span>
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
In particular, it describes objects for configuring aspects of a
process implementing Simplified Multicast Forwarding (SMF) [<a href="./rfc6621" title=""Simplified Multicast Forwarding"">RFC6621</a>]
for Mobile Ad Hoc Networks (MANETs). SMF provides multicast
Duplicate Packet Detection (DPD) and supports algorithms for
constructing an estimate of a MANET Minimum Connected Dominating Set
(MCDS) for efficient multicast forwarding. The SMF-MIB module also
reports state information, performance information, and
notifications. In addition to configuration, this additional state
and performance information is useful to operators troubleshooting
multicast forwarding problems.
<span class="h2"><a class="selflink" id="section-2" href="#section-2">2</a>. The Internet-Standard Management Framework</span>
For a detailed overview of the documents that describe the current
Internet-Standard Management Framework, please refer to <a href="./rfc3410#section-7">section 7 of
RFC 3410</a> [<a href="./rfc3410" title=""Introduction and Applicability Statements for Internet- Standard Management Framework"">RFC3410</a>].
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,
<a href="./rfc2578">RFC 2578</a> [<a href="./rfc2578" title=""Structure of Management Information Version 2 (SMIv2)"">RFC2578</a>], STD 58, <a href="./rfc2579">RFC 2579</a> [<a href="./rfc2579" title=""Textual Conventions for SMIv2"">RFC2579</a>] and STD 58, <a href="./rfc2580">RFC 2580</a>

<span class="h2"><a class="selflink" id="section-4" href="#section-4">4</a>. Overview</span>
SMF provides methods for implementing DPD-based multicast forwarding
with the optional use of CDS-based relay sets. The CDS provides a
complete connected coverage of the nodes comprising the MANET. The
MCDS is the smallest set of MANET nodes (comprising a connected
cluster) that cover all the nodes in the cluster with their
transmissions. As the density of the MANET nodes increase, the
fraction of nodes required in an MCDS decreases. Using the MCDS as a
multicast forwarding set then becomes an efficient multicast
mechanism for MANETs.

<span class="grey"><a href="./rfc7367">RFC 7367</a> The SMF-MIB October 2014</span>
Various algorithms for the construction of estimates of the MCDS
exist. The Simplified Multicast Framework [<a href="./rfc6621" title=""Simplified Multicast Forwarding"">RFC6621</a>] describes some
of these. It further defines various operational modes for a node
that is participating in the collective creation of the MCDS
estimates. These modes depend upon the set of related MANET routing
and discovery protocols and mechanisms in operation in the specific
MANET node.
A SMF router's MIB module contains SMF process configuration
parameters (e.g., specific CDS algorithm), state information (e.g.,
current membership in the CDS), performance counters (e.g., packet
counters), and notifications.
<span class="h3"><a class="selflink" id="section-4.1" href="#section-4.1">4.1</a>. SMF Management Model</span>
This section describes the management model for the SMF node process.
Figure 1 (reproduced from Figure 1 of [<a href="./rfc6621" title=""Simplified Multicast Forwarding"">RFC6621</a>]) shows the
relationship between the SMF Relay Set Selection Algorithm and the
related algorithms, processes, and protocols running in the MANET
nodes. The Relay Set Selection Algorithm (RSSA) can rely upon
topology information acquired from the MANET Neighborhood Discovery
Protocol (NHDP), from the specific MANET routing protocol running on
the node, or from Layer 2 information passed up to the higher layer
protocol processes.

<span class="h3"><a class="selflink" id="section-4.2" href="#section-4.2">4.2</a>. Terms</span>
The following definitions apply throughout this document:
Configuration Objects: switches, tables, and objects that are
initialized to default settings or set through the management
interfaces such as defined by this MIB module.
Tunable Configuration Objects: objects whose values affect timing or
attempt bounds on the SMF Relay Set (RS) process.
State Objects: automatically generated values that define the
current operating state of the SMF RS process in the router.
Performance Objects: automatically generated values that help an
administrator or automated tool to assess the performance of the
CDS multicast process on the router and the overall multicast
performance within the MANET routing domain.
<span class="h2"><a class="selflink" id="section-5" href="#section-5">5</a>. Structure of the MIB Module</span>
This section presents the structure of the SMF-MIB module. The
objects are arranged into the following groups:
o smfMIBNotifications - defines the notifications associated with
the SMF process.
o smfMIBObjects - defines the objects forming the basis for the SMF-
MIB module. These objects are divided up by function into the
following groups:
* Capabilities Group - This group contains the SMF objects that
the device uses to advertise its local capabilities with
respect to, e.g., the supported RSSAs.
* Configuration Group - This group contains the SMF objects that
configure specific options that determine the overall operation
of the SMF process and the resulting multicast performance.
* State Group - Contains information describing the current state
of the SMF process such as the Neighbor Table.
* Performance Group - Contains objects that help to characterize
the performance of the SMF process, typically counters for
statistical computations.
o smfMIBConformance - defines two, i.e., minimal and full,
conformance implementations for the SMF-MIB module.

<span class="h3"><a class="selflink" id="section-5.1" href="#section-5.1">5.1</a>. Textual Conventions</span>
The Textual Conventions defined within the SMF-MIB module:
o The SmfStatus is defined within the SMF-MIB module. This contains
the current operational status of the SMF process on an interface.
The Textual Conventions defined for the SMF-MIB module and maintained
by IANA are:
o The IANAsmfOpModeIdTC represents an index that identifies a
specific SMF operational mode. This Textual Convention is
maintained by IANA in the IANA-SMF-MIB.
o The IANAsmfRssaIdTC represents an index that identifies, through
reference, a specific RSSA available for operation on the device.
This Textual Convention is maintained by IANA also in the IANA-
SMF-MIB.
<span class="h3"><a class="selflink" id="section-5.2" href="#section-5.2">5.2</a>. The Capabilities Group</span>
The SMF device supports a set of capabilities. The list of
capabilities that the device can advertise is as follows:
o Operational Mode - topology information from NHDP, CDS-aware
unicast routing, or Cross-layer from Layer 2.
o SMF RSSA - the specific RSSA operational on the device. Note that
configuration, state, and performance objects related to a
specific RSSA must be defined within a separate MIB module.
<span class="h3"><a class="selflink" id="section-5.3" href="#section-5.3">5.3</a>. The Configuration Group</span>
The SMF device is configured with a set of controls. Some of the
prominent configuration controls for the SMF device are:
o Operational Mode - determines from where topology information is
derived, e.g., NHDP, CDS-aware unicast routing, or Cross-layer
from Layer 2.
o SMF RSSA - the specific RSSA operational on the device.
o Duplicate Packet detection for IPv4 - Identification-based or
Hash-based DPD (I-DPD or H-DPD, respectively).
o Duplicate Packet detection for IPv6 - Identification-based or
Hash-based DPD.

<span class="grey"><a href="./rfc7367">RFC 7367</a> The SMF-MIB October 2014</span>
o SMF Type Message TLV - if NHDP mode is selected, then the SMF Type
Message TLV MAY be included in the NHDP exchanges.
o SMF Address Block TLV - if NHDP mode is selected, then the SMF
Address Block TLV SHOULD be included in the NHDP exchanges.
o SMF Address Forwarding Table - a table identifying configured
multicast addresses to be forwarded by the SMF process.
<span class="h3"><a class="selflink" id="section-5.4" href="#section-5.4">5.4</a>. The State Group</span>
The State sub-tree reports current state information, for example,
o Node RSSA State - identifies whether the node is currently in or
out of the Relay Set.
o Neighbors Table - a table containing current one-hop neighbors and
their operational RSSA.
<span class="h3"><a class="selflink" id="section-5.5" href="#section-5.5">5.5</a>. The Performance Group</span>
The Performance sub-tree primarily reports counters that relate to
SMF RSSA performance. The SMF performance counters consist of per-
node and per-interface objects:
o Total multicast packets received.
o Total multicast packets forwarded.
o Total duplicate multicast packets detected.
o Per interface statistics table with the following entries:
* Multicast packets received.
* Multicast packets forwarded.
* Duplicate multicast packets detected.
<span class="h3"><a class="selflink" id="section-5.6" href="#section-5.6">5.6</a>. The Notifications Group</span>
The Notifications sub-tree contains the list of notifications
supported within the SMF-MIB module and their intended purpose and
utility.

<span class="h3"><a class="selflink" id="section-5.7" href="#section-5.7">5.7</a>. Tables and Indexing</span>
The SMF-MIB module contains a number of tables that record data
related to:
o configuration and operation of packet forwarding on the local
router,
o configuration and operation of local MANET interfaces on the
router, and
o configuration and operation of various RSSAs for packet
forwarding.
The SMF-MIB module's tables are indexed via the following constructs:
o smfCapabilitiesIndex - the index identifying the combination of
SMF mode and SMF RSSA available on this device.
o smfCfgAddrForwardingIndex - the index to configured multicast
address lists that are forwarded by the SMF process.
o smfCfgIfIndex - the IfIndex of the interface on the local router
on which SMF is configured.
o smfStateNeighborIpAddrType, smfStateNeighborIpAddr, and
smfStateNeighborPrefixLen - the interface index set of specific
one-hop neighbor nodes to this local router.
These tables and their associated indexing are defined in the SMF-MIB
module:
o smfCapabilitiesTable - identifies the resident set of (SMF
Operational Modes, SMF RSSA algorithms) available on this router.
This table has 'INDEX { smfCapabilitiesIndex }'.
o smfCfgAddrForwardingTable - contains information on multicast
addresses that are to be forwarded by the SMF process on this
device. This table has 'INDEX { smfCfgAddrForwardingIndex }'.
o smfCfgInterfaceTable - describes the SMF interfaces on this device
that are participating in the SMF packet forwarding process. This
table has 'INDEX { smfCfgIfIndex }'.

<span class="grey"><a href="./rfc7367">RFC 7367</a> The SMF-MIB October 2014</span>
o smfStateNeighborTable - describes the current neighbor nodes,
their addresses and the SMF RSSA and the interface on which they
can be reached. This table has 'INDEX {
smfStateNeighborIpAddrType, smfStateNeighborIpAddr,
smfStateNeighborPrefixLen }'.
o smfPerfIpv4InterfacePerfTable - contains the IPv4-related SMF
statistics per each SMF interface on this device. This table has
'INDEX { smfCfgIfIndex }'.
o smfPerfIpv6InterfacePerfTable - contains the IPv6-related SMF

<span class="h3"><a class="selflink" id="section-6.1" href="#section-6.1">6.1</a>. Relationship to the SNMPv2-MIB</span>
The 'system' group in the SNMPv2-MIB module [<a href="./rfc3418" title=""Management Information Base (MIB) for the Simple Network Management Protocol (SNMP)"">RFC3418</a>] is defined as
being mandatory for all systems, and the objects apply to the entity
as a whole. The 'system' group provides identification of the
management entity and certain other system-wide data. The SMF-MIB
module does not duplicate those objects.
<span class="h3"><a class="selflink" id="section-6.2" href="#section-6.2">6.2</a>. Relationship to the IP-MIB</span>
It is an expectation that SMF devices will implement the standard IP-
MIB module [<a href="./rfc4293" title=""Management Information Base for the Internet Protocol (IP)"">RFC4293</a>]. Exactly how to integrate SMF packet handling

the experiment.
The SMF-MIB module counters within the smfPerformanceGroup count
packets handled by the system and interface local SMF process (as
discussed above). Not all IP (unicast and multicast) packets on a
device interface are handled by the SMF process. So the counters are
tracking different packet streams in the IP-MIB and SMF-MIB modules.

In a sense, the SMF-MIB module is a general front-end to a set of
yet-to-be developed RSSA-specific MIB modules. These RSSA-specific
MIB modules will define the objects for the configuration, state,
performance and notification required for the operation of these
specific RSSAs. The SMF-MIB module Capabilities Group allows the
remote management station the ability to query the router to discover

<a href="./rfc5132">RFC 5132</a> manages traditional IP-based multicast (based
upon multicast routing mechanisms). The SMF-MIB module
provides management for a MANET subnet-based flooding
mechanism that may be used for multicast transport
(through SMF broadcast) depending upon the MANET dynamics
and other factors regarding the MANET subnet. Further,
they may coexist in certain MANET deployments
using the smfCfgAddrForwardingTable to hand certain IP
multicast addresses to the SMF process and other IP
multicast packets to be forwarded by other
multicast mechanisms that are IP route based. SMF and
the associated SMF-MIB module are experimental and these
are some of the experiments to be had with SMF and
the SMF-MIB module.
This is the (conceptual) table containing information on
multicast addresses that are to be forwarded by the SMF
process. This table represents an IP filters table for
forwarding (or not) packets based upon their IP
multicast address.
The SMF process can be configured to forward only those
multicast addresses found within the
smfCfgAddrForwardingTable. As such, addresses that are
to be forwarded by the SMF process MUST be found within
the address ranges configured within this table, unless
this table is empty.
Each row is associated with a range of multicast
addresses, and ranges for different rows must be disjoint.
Different rows MAY share a common
smfCfgAddrForwardingGroupName to administratively
associate different rows.
The objects in this table are persistent and, when written,

operate over this interface.
A conceptual row in this table exists if and only
if either a manager has explicitly created the row
or there is an interface on the managed device
that automatically supports and runs SMF as part
of the device's initialization process.
The manager creates a row in this table by setting
the rowStatus to 'createAndGo' or 'createAndWait'.
Row objects having associated DEFVAL clauses are

values during row creation, unless the manager
explicitly defines these object values during the
row creation.
As the smfCfgInterfaceTable sparsely augments the
IfTable. Hence,
+ an entry cannot exist in smfCfgInterfaceTable
without a corresponding entry in the ifTable.
+ if an entry in the ifTable is removed, the
corresponding entry (if it exists) in the
smfCfgInterfaceTable MUST be removed.
+ the smfCfgIfStatus can have a value of
'enabled' or 'disabled' independent of the
current value of the ifAdminStatus of the
corresponding entry in the ifTable.
The values of the objects smfCfgAdminStatus and
smfCfgIfAdminStatus reflect the up-down status of
the SMF process running on the device and on the
specific interfaces, respectively. Hence,
+ the value of the smfCfgAdminStatus can be
'enabled' or 'disabled' reflecting the current
running status of the SMF process on the device.
+ the value of the smfCfgIfAdminStatus can be
'enabled' or 'disabled' if the value of the
smfCfgAdminStatus is set to 'enabled'.
+ if the value of the smfCfgAdminStatus is
'disabled', then the corresponding
smfCfgIfAdminStatus objects MUST be set
to 'disabled' in the smfCfgInterfaceTable.
+ once the value of the smfCfgAdminStatus changes
from 'disabled' to 'enabled', it is up to the
management system to make the corresponding
changes to the smfCfgIfAdminStatus values
back to 'enabled'.

<span class="h2"><a class="selflink" id="section-8" href="#section-8">8</a>. IANA-SMF-MIB Definitions</span>
This section contains the IANA-SMF-MIB module. This MIB module
defines two Textual Conventions for which IANA SHOULD maintain and
keep synchronized with the registry identified below within the
IANAsmfOpModeIdTC and the IANAsmfRssaIdTC TEXTUAL-CONVENTIONs.
The IANAsmfOpModeIdTC defines an index that identifies through
reference to a specific SMF operations mode. The index is an integer
valued named-number enumeration consisting of an integer and label.
IANA is to create and maintain this Textual Convention. Future
assignments are made to anyone on a first come, first served basis.
There is no substantive review of the request, other than to ensure
that it is well-formed and does not duplicate an existing assignment.
However, requests must include a minimal amount of clerical
information, such as a point of contact (including an email address)
and a brief description of the method being identified as a new SMF
operations mode.
The IANAsmfRssaIdTC defines an index that identifies through
reference to a specific Reduced Set Selection Algorithm (RSSA). The
index is an integer valued named-number enumeration consisting of an
integer and label. IANA is to create and maintain this Textual
Convention.
Future assignments to the IANAsmfRssaIdTC for the index range 5-127
require an RFC publication (either as an IETF submission or as an
Independent submission [<a href="./rfc5742" title=""IESG Procedures for Handling of Independent and IRTF Stream Submissions"">RFC5742</a>]). The category of RFC MUST be
Standards Track. The specific RSSAs MUST be documented in sufficient
detail so that interoperability between independent implementations
is possible.

<span class="grey"><a href="./rfc7367">RFC 7367</a> The SMF-MIB October 2014</span>
Future assignments to the IANAsmfRssaIdTC for the index range 128-239
are private or local use only, with the type and purpose defined by
the local site. No attempt is made to prevent multiple sites from
using the same value in different (and incompatible) ways. There is
no need for IANA to review such assignments (since IANA will not
record these), and assignments are not generally useful for broad
interoperability. It is the responsibility of the sites making use
of the Private Use range to ensure that no conflicts occur (within
the intended scope of use).
Future assignments to the IANAsmfRssaIdTC for the index range 240-255
are to facilitate experimentation. These require an RFC publication
(either as an IETF submission or as an Independent submission
[<a href="./rfc5742" title=""IESG Procedures for Handling of Independent and IRTF Stream Submissions"">RFC5742</a>]). The category of RFC MUST be Experimental. The RSSA
algorithms MUST be documented in sufficient detail so that
interoperability between independent implementations is possible.

DESCRIPTION
"An index that identifies through reference to a specific
SMF operations mode. There are basically three styles
of SMF operation with reduced relay sets currently
identified:
Independent operation 'independent(1)' -
SMF performs its own relay
set selection using information from an associated
MANET NHDP process.
CDS-aware unicast routing operation 'routing(2)'-
a coexistent unicast routing
protocol provides dynamic relay
set state based upon its own control plane
Connected Dominating Set (CDS) or neighborhood
discovery information.
Cross-layer operation 'crossLayer(3)' -
SMF operates using neighborhood
status and triggers from a
cross-layer information base for dynamic relay
set selection and maintenance.
IANA MUST update this Textual Convention accordingly.
The definition of this Textual Convention with the
addition of newly assigned values is updated
periodically by the IANA, in the
IANA-maintained registries. (The
latest arrangements can be obtained by contacting the

DESCRIPTION
"An index that identifies through reference to specific
RSSAs. Several are currently defined
in the Appendices A, B, and C of <a href="./rfc6621">RFC 6621</a>.
Examples of RSSAs already identified within
this Textual Convention (TC) are:
Classical Flooding (cF(1)) - is the standard
flooding algorithm where each node in the next
retransmits the information on each of its interfaces.
Source-Based Multipoint Relay (sMPR(2)) -
this algorithm is used by Optimized Link State Routing
(OLSR) and OLSR version 2 (OLSRv2) protocols for the
relay of link state updates and other control
information (<a href="./rfc3626">RFC 3626</a>, <a href="./rfc7181">RFC 7181</a>). Since each router
picks its neighboring relays independently, sMPR
forwarders depend upon previous hop information
(e.g., source Media Access Control (MAC) address) to
operate correctly.
Essential Connected Dominating Set (eCDS(3)) -
defined in <a href="./rfc5614">RFC 5614</a>, this algorithm forms a single
CDS mesh for the SMF operating region. Its
packet-forwarding rules are not dependent upon
previous hop knowledge in contrast to sMPR.
Multipoint Relay Connected Dominating Set (mprCDS(4)) -
This algorithm is an extension to the basic sMPR
election algorithm that results in a shared
(non-source-specific) SMF CDS. Thus, its forwarding

<span class="h2"><a class="selflink" id="section-9" href="#section-9">9</a>. Security Considerations</span>
This section discusses security implications of the choices made in
this SMF-MIB module.
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:
o 'smfCfgAdminStatus' - this writable configuration object controls
the operational status of the SMF process. If this setting is
configured inconsistently across the MANET multicast domain, then
delivery of multicast data may be inconsistent across the domain;
some nodes may not receive multicast data intended for them.
o 'smfCfgRouterIDAddrType' and 'smfCfgRouterID' - these writable
configuration objects define the ID of the SMF process. These
objects should be configured with a routable address defined on
the local SMF device. The smfCfgRouterID is a logical
identification that MUST be configured as unique across
interoperating SMF neighborhoods, and it is RECOMMENDED to be
chosen as the numerically largest address contained in a node's
'Neighbor Address List' as defined in NHDP. A smfCfgRouterID MUST
be unique within the scope of the operating MANET network
regardless of the method used for selecting it. If these objects
are misconfigured or configured inconsistently across the MANET,
then the ability of various RSSAs, e.g., eCDS, may be compromised.
This would potentially result in some routers within the MANET not
receiving multicast packets destine to them. Hence, intentionally
misconfiguring these objects could pose a form of Denial-of-
Service (DoS) attack against the MANET.
o 'smfCfgOpMode' - this writable configuration object defines the
operational mode of the SMF process. The operational mode defines
how the SMF process receives its data to form its local estimate
of the CDS. It is recommended that the value for this object be
set consistently across the MANET to ensure proper operation of
the multicast packet forwarding. If the value for this object is
set inconsistently across the MANET, the result may be that
multicast packet delivery will be compromised within the MANET.
Hence, intentionally misconfiguring this object could pose a form
DoS attack against the MANET.
<span class="grey">Cole, et al. Experimental [Page 56]</span></pre>
<hr class='noprint'/><!--NewPage--><pre class='newpage'><span id="page-57" ></span>
<span class="grey"><a href="./rfc7367">RFC 7367</a> The SMF-MIB October 2014</span>
o 'smfCfgRssa' - this writable configuration object sets the
specific RSSA for the SMF process. If this object is set
inconsistently across the MANET domain, multicast delivery of data
will likely fail. Hence, intentionally misconfiguring this object
could pose a form DoS attack against the MANET.
o 'smfCfgRssaMember' - this writable configuration object sets the
'interest' of the local SMF node in participating in the CDS.
Setting this object to 'never(3)' on a highly connected device
could lead to frequent island formation. Setting this object to
'always(2)' could support data ex-filtration from the MANET
domain.
o 'smfCfgIpv4Dpd' - this writable configuration object sets the
duplicate packet detection method, i.e., H-DPD or I-DPD, for
forwarding of IPv4 multicast packets. Forwarders may operate with
mixed H-DPD and I-DPD modes as long as they consistently perform
the appropriate DPD routines outlined in [<a href="./rfc6621" title=""Simplified Multicast Forwarding"">RFC6621</a>]. However, it
is RECOMMENDED that a deployment be configured with a common mode
for operational consistency.
o 'smfCfgIpv6Dpd' - this writable configuration object sets the
duplicate packet detection method for the forwarding of IPv6
multicast packets. Since IPv6 SMF does specify an option header,
the interoperability constraints are not as loose as in the IPv4
version, and forwarders SHOULD NOT operate with mixed H-DPD and
I-DPD modes. Hence, the value for this object SHOULD be
consistently set within the forwarders comprising the MANET, else
inconsistent forwarding may result unnecessary multicast packet
dropping.
o 'smfCfgMaxPktLifetime' - this writable configuration object sets
the estimate of the network packet traversal time. If set too
small, this could lead to poor multicast data delivery ratios
throughout the MANET domain. This could serve as a form of DoS
attack if this object value is set too small.
o 'smfCfgDpdEntryMaxLifetime' - this writable configuration object
sets the maximum lifetime (in seconds) for the cached DPD records
for the combined IPv4 and IPv6 methods. If the memory is running
low prior to the MaxLifetime being exceeded, the local SMF devices
should purge the oldest records first. If this object value is
set too small, then the effectiveness of the SMF DPD algorithms
may become greatly diminished causing a higher than necessary
packet load on the MANET.

<span class="grey"><a href="./rfc7367">RFC 7367</a> The SMF-MIB October 2014</span>
o 'smfCfgNhdpRssaMesgTLVIncluded' - this writable configuration
object indicates whether or not the associated NHDP messages
include the RSSA Message TLV. It is highly RECOMMENDED that this
object be set to 'true(1)' when the SMF operation mode is set to
independent as this information will inform the local forwarder of
the RSSA implemented in neighboring forwarders and is used to
ensure consistent forwarding across the MANET. While it is
possible that SMF neighbors MAY be configured differently with
respect to the RSSA and still operate cooperatively, but these
cases will vary dependent upon the algorithm types designated and
this situation SHOULD be avoided.
o 'smfCfgNhdpRssaAddrBlockTLVIncluded' - this writable configuration
object indicates whether or not the associated NHDP messages
include the RSSA Address Block TLV. The
smfNhdpRssaAddrBlockTLVIncluded is optional in all cases as it
depends on the existence of an address block that may not be
present. If this SMF device is configured with NHDP, then this
object should be set to 'true(1)' as this TLV enables CDS relay
algorithm operation and configuration to be shared among 2-hop
neighborhoods. Some relay algorithms require 2-hop neighbor
configuration in order to correctly select relay sets.
o 'smfCfgAddrForwardingTable' - the writable configuration objects
in this table indicate which multicast IP addresses are to be
forwarded by this SMF node. Misconfiguration of rows within this
table can limit the ability of this SMF device to properly forward
multicast data.
o 'smfCfgInterfaceTable' - the writable configuration objects in
this table indicate which SMF node interfaces are participating in
the SMF packet forwarding process. Misconfiguration of rows
within this table can limit the ability of this SMF device to
properly forward multicast data.
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:
o 'smfNodeRsStatusIncluded' - this readable state object indicates
whether or not this SMF node is part of the CDS. Being part of
the CDS makes this node a distinguished device. It could be
exploited for data ex-filtration, or DoS attacks.
<span class="grey">Cole, et al. Experimental [Page 58]</span></pre>
<hr class='noprint'/><!--NewPage--><pre class='newpage'><span id="page-59" ></span>
<span class="grey"><a href="./rfc7367">RFC 7367</a> The SMF-MIB October 2014</span>
o 'smfStateNeighborTable' - the readable state objects in this table
indicate current neighbor nodes to this SMF node. Exposing this
information to an attacker could allow the attacker easier access
to the larger MANET domain.
The remainder of the objects in the SMF-MIB module are performance
counter objects. While these give an indication of the activity of
the SMF process on this node, it is not expected that exposing these
values poses a security risk to the MANET network.
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.
Implementations SHOULD provide the security features described by the
SNMPv3 framework (see [<a href="./rfc3410" title=""Introduction and Applicability Statements for Internet- Standard Management Framework"">RFC3410</a>]), and implementations claiming
compliance to the SNMPv3 standard MUST include full support for
authentication and privacy via the User-based Security Model (USM)
[<a href="./rfc3414" title=""User-based Security Model (USM) for version 3 of the Simple Network Management Protocol (SNMPv3)"">RFC3414</a>] with the AES cipher algorithm [<a href="./rfc3826" title=""The Advanced Encryption Standard (AES) Cipher Algorithm in the SNMP User-based Security Model"">RFC3826</a>]. Implementations
MAY also provide support for the Transport Security Model (TSM)
[<a href="./rfc5591" title=""Transport Security Model for the Simple Network Management Protocol (SNMP)"">RFC5591</a>] in combination with a secure transport such as SSH
[<a href="./rfc5592" title=""Secure Shell Transport Model for the Simple Network Management Protocol (SNMP)"">RFC5592</a>] or TLS/DTLS [<a href="./rfc6353" title=""Transport Layer Security (TLS) Transport Model for the Simple Network Management Protocol (SNMP)"">RFC6353</a>].
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.
<span class="h2"><a class="selflink" id="section-10" href="#section-10">10</a>. Applicability Statement</span>
This document describes objects for configuring parameters of the
Simplified Multicast Forwarding [<a href="./rfc6621" title=""Simplified Multicast Forwarding"">RFC6621</a>] process on a Mobile Ad Hoc
Network (MANET) router. This MIB module, denoted SMF-MIB, also
reports state and performance information and notifications. This
section provides some examples of how this MIB module can be used in
MANET network deployments. A fuller discussion of MANET network
management use cases and challenges is out of scope for this
document.
SMF is designed to allow MANET routers to forward IPv4 and IPv6
packets over the MANET and cover the MANET nodes through the
automatic discovery of efficient estimates of the Minimum Connected
Dominating Set (MCDS) of nodes within the MANET. The MCDS is

<span class="grey"><a href="./rfc7367">RFC 7367</a> The SMF-MIB October 2014</span>
estimated using the Relay Set Selection Algorithms (RSSAs) discussed
within this document. In the following, three scenarios are listed
where this MIB module is useful:
o For a Parking Lot Initial Configuration Situation - it is common
for the vehicles comprising the MANET being forward deployed at a
remote location, e.g., the site of a natural disaster, to be off-
loaded in a parking lot where an initial configuration of the
networking devices is performed. The configuration is loaded into
the devices from a fixed-location Network Operations Center (NOC)
at the parking lot, and the vehicles are stationary at the parking
lot while the configuration changes are made. Standards-based
methods for configuration management from the co-located NOC are
necessary for this deployment option. The set of interesting
configuration objects for the SMF process are listed within this
MIB module.
o For Mobile vehicles with Low Bandwidth Satellite Link to a Fixed
NOC - Here the vehicles carrying the MANET routers carry multiple
wireless interfaces, one of which is a relatively low-bandwidth
on-the-move satellite connection that interconnects a fix NOC to
the nodes of the MANET. Standards-based methods for monitoring
and fault management from the fixed NOC are necessary for this
deployment option.
o For Fixed NOC and Mobile Local Manager in Larger Vehicles - for
larger vehicles, a hierarchical network management arrangement is
useful. Centralized network management is performed from a fixed
NOC while local management is performed locally from within the
vehicles. Standards-based methods for configuration, monitoring,
and fault management are necessary for this deployment option.
Here we provide an example of the simplest of configurations to
establish an operational multicast forwarding capability in a MANET.
This discussion only identifies the configuration necessary through
the SMF-MIB module and assumes that other configuration has occurred.
Assume that the MANET is to support only IPv4 addressing and that the
MANET nodes are to be configured in the context of the Parking Lot
Initialization case above. Then, the SMF-MIB module defines ten
configuration OIDs and two configuration tables, i.e., the
smfCfgAddrForwardingTable and the smfCfgInterfaceTable. Of the ten
OIDs defined, all but one, i.e., the smfCfgRouterID, have DEFVAL
clauses that allow for a functional configuration of the SMF process
within the MANET. The smfCfgRouterIDType defaults to 'ipv4' so the
smfCfgRouterID can be set as, e.g., (assuming the use of the Net-SNMP
toolkit),:
snmpset [options] <smfCfgRouterID_OID>.0 a 192.0.2.100
<span class="grey">Cole, et al. Experimental [Page 60]</span></pre>
<hr class='noprint'/><!--NewPage--><pre class='newpage'><span id="page-61" ></span>
<span class="grey"><a href="./rfc7367">RFC 7367</a> The SMF-MIB October 2014</span>
If the smfCfgAddrForwardingTable is left empty, then the SMF local
forwarder will forward all multicast addresses. So this table does
not require configuration if you want to have the MANET forward all
multicast addresses.
All that remains is to configure at least one row in the
smfCfgInterfaceTable. Assume that the node has a wireless interface
with an <ifName>='wlan0' and an <ifIndex>='1'. All of the objects in
the rows of the smfCfgInterfaceTable have a DEFVAL clause; hence,
only the RowStatus object needs to be set. So the SMF process will
be activated on the 'wlan0' interface by the following network
manager snmpset command:
snmpset [options] <smfCfgIfRowStatus>.1 i active(1)
At this point, the configured forwarder will begin a Classical
Flooding algorithm to forward all multicast addresses IPv4 packets it
receives.
To provide a more efficient multicast forwarding within the MANET,
the network manager could walk the smfCapabilitiesTable to identify
other SMF Operational Modes, for example:
snmpwalk [options] <smfCapabilitiesTable>
SMF-MIB::smfCapabilitiesIndex.1 = INTEGER: 1
SMF-MIB::smfCapabilitiesIndex.2 = INTEGER: 2
SMF-MIB::smfCapabilitiesOpModeID.1 = INTEGER: cfOnly(1)
SMF-MIB::smfCapabilitiesOpModeiD.2 = INTEGER: independent(2)
SMF-MIB::smfCapabilitiesRssaID.1 = INTEGER: cF(1)
SMF-MIB::smfCapabilitiesRssaID.2 = INTEGER: eCDS(3)
In this example, the forwarding device also supports the Essential
Connected Dominating Set (eCDS) RSSA with the forwarder in the
'independent(2)' operational mode. If the network manager were to
then issue an snmpset, for example:
snmpset [options] <smfCfgOperationalMode>.0 i 2
then the local forwarder would switch its forwarding behavior from
Classical Flooding to the more efficient eCDS flooding.
