Internet-Draft The SMF MIB October 2011
1. Introduction
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)
[I-D.ietf-manet-smf] 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 also reports state information, performance metrics, and
notifications. In addition to configuration, this additional state
and performance information is useful to operators troubleshooting
multicast forwarding problems.
2. 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].
3. Conventions
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].
4. Overview
SMF provides methods for implementing DPD-based multicast forwarding
with the optional use of Connected Dominating Set (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) which 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.
Cole, et al. Expires April 4, 2012 [Page 3]
Internet-Draft The SMF MIB October 2011
Various algorithms for the construction of estimates of the MCDS
exist. The Simplified Multicast Framework [I-D.ietf-manet-smf]
describes some of these. It further defines various operational
modes for a node which 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 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.
4.1. SMF Management Model
This section describes the management model for the SMF node process.
Figure 1 (reproduced from Figure 4 of [I-D.ietf-manet-smf]) 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 gotten 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.

4.2. Terms
The following definitions apply throughout this document:
o Configuration Objects - switches, tables, objects which are
initialized to default settings or set through the management
interface defined by this MIB.
o Tunable Configuration Objects - objects whose values affect timing
or attempt bounds on the SMF RS process.
o State Objects - automatically generated values which define the
current operating state of the SMF RS process in the router.
o Performance Objects - automatically generated values which help an
administrator or automated tool to assess the performance of the
CDS multicast process on the router and the overall multicasting
performance within the MANET routing domain.
5. Structure of the MIB Module
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-MIB.
Cole, et al. Expires April 4, 2012 [Page 5]
Internet-Draft The SMF MIB October 2011
o smfMIBObjects - defines the objects forming the basis for the SMF-
MIB. These objects are divided up by function into the following
groups:
o
* 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 RSSA and the resulting multicast performance.
* State Group - Contains information describing the current state
of the SMF RSSA process such as the Neighbor Table.
* Performance Group - Contains objects which help to characterize
the performance of the SMF RSSA process, typically statistics
counters.
o smfMIBConformance - defines minimal and full conformance of
implementations to this SMF-MIB.
5.1. Textual Conventions
The textual conventions defined within the SMF-MIB are as follows:
o The SmfStatus is defined within the SMF-MIB. This contains the
current operational status of the SMF process on an interface.
o The SmfOpModeID represents an index that identifies a specific SMF
operational mode.
o The SmfRssaID represents an index that identifies, through
reference, a specific RSSA available for operation on the device.
5.2. The Capabilities Group
The SMF device supports a set of capabilities. The list of
capabilities which the device can advertise are:
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 another separate MIB.
Cole, et al. Expires April 4, 2012 [Page 6]
Internet-Draft The SMF MIB October 2011
5.3. The Configuration Group
The SMF device is configured with a set of controls. Some of the
prominent configuration controls for the SMF device follow:
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.
o Duplicate Packet detection for IPv4 - Identification-based or
Hash-based DPD.
o Duplicate Packet detection for IPv6 - Identification-based or
Hash-based DPD.
o SMF Type Message TLV - if NHDP mode is selected, then is the SMF
Type Message TLV may be included in the NHDP exchanges.
o SMF Address Block TLV - if NHDP mode is selected, then is the SMF
Address Block TLV should be included in the NHDP exchanges.
5.4. The State Group
The State Subtree reports current state information, e.g.,
o Node RSS State - is the node currently in or out of the Relay Set.
o Neighbors Table - a table containing current neighbors and their
operational RSSA.
5.5. The Performance Group
The Performance subtree reports primarily counters that relate to SMF
RSSA performance. The SMF performance counters consists 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:
o
Cole, et al. Expires April 4, 2012 [Page 7]
Internet-Draft The SMF MIB October 2011
* Multicast packets received.
* Multicast packets forwarded.
* Duplicate multicast packets detected.
5.6. The Notifications Group
The Notifications Subtree contains the list of notifications
supported within the SMF-MIB and their intended purpose or utility.
6. Relationship to Other MIB Modules
6.1. Relationship to the SNMPv2-MIB
The 'system' group in the SNMPv2-MIB [RFC3418] 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 does not
duplicate those objects.
6.2. MIB modules required for IMPORTS
The textual conventions imported for use in the SMF-MIB are as
follows. The MODULE-IDENTITY, OBJECT-TYPE, NOTIFICATION-TYPE,
Counter32, Unsigned32, Integer32 and mib-2 textual conventions are
imported from RFC 2578 [RFC2578]. The TEXTUAL-CONVENTION, RowStatus
and TruthValue textual conventions are imported from RFC 2579
[RFC2579]. The MODULE-COMPLIANCE, OBJECT-GROUP and NOTIFICATION-
GROUP textual conventions are imported from RFC 2580 [RFC2580]. The
InterfaceIndexOrZero textual convention is imported from RFC 2863
[RFC2863]. The SnmpAdminString textual convention is imported from
RFC 3411 [RFC3411]. The InetAddress, InetAddressType and
InetAddressPrefixLength textual conventions are imported from RFC
4001 [RFC4001].
6.3. Relationship to the Future RSSA-MIBs
In a sense, the SMF-MIB is a general front-end to a set of, yet to be
developed, RSSA-specific MIBs. These RSSA-specific MIBs will define
the objects for the configuration, state, performance and
notification objects required for the operation of these specific
RSSAs. The SMF-MIB Capabilities Group allows the remote management
station the ability to query the router to discover the set of
supported RSSAs.

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 smfRouterID MUST be
unique within the scope of the operating
MANET network regardless of the method used
for selecting it.

8. Security Considerations
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 'smfAdminStatus' - this writable configuration object controls the
operational status of the SMF process. If this setting is
configured inconsistently across the MANET multicasting domain,
then delivery of multicast data may be inconsistent across the
domain; some nodes may not receive multicast data intended for
Cole, et al. Expires April 4, 2012 [Page 48]
Internet-Draft The SMF MIB October 2011
them.
o 'smfRouterIDAddrType' and 'smfRouterID' - 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 smfRouterID is a logical identification
that MUST be consistent 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 smfRouterID MUST be unique within the scope of the
operating MANET network regardless of the method used for
selecting it.
o 'smfConfiguredOpMode' - this writable configuration objects define
the operational mode of the SMF process. The operational mode
defines how the SMF process develops its local estimate of the
CDS.
o 'smfConfiguredRssa' - this writable configuration object sets the
specific Reduced Set Selection Algorithm (RSSA) for the SMF
process. If this object is set inconsistently across the MANET
domain, multicast delivery of data will fail.
o 'smfRssaMember' - 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 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 'smfIpv4Dpd' - this writable configuration object sets the
duplicate packet detection method for forwarding of IPv4 multicast
packets.
o 'smfIpv6Dpd' - this writable configuration object sets the
duplicate packet detection method for forwarding of IPv6 multicast
packets.
o 'smfMaxPktLifetime' - 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.
o 'smfDpdMaxMemorySize' - this writable configuration object sets
the memory storage size (in Kilo-Bytes) for the cached DPD records
for the combined IPv4 and IPv6 methods. If set too small this
could lead to poor performance of the duplicate packet protection
algorithms and lead to inefficient resource, e.g., link,
Cole, et al. Expires April 4, 2012 [Page 49]
Internet-Draft The SMF MIB October 2011
utilization within the MANET domain. The local SMF device should
protect itself against memory overruns in the event that too large
a setting is requested.
o 'smfDpdEntryMaxLifetime' - 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 MaxLifetimes being exceeded, the local SMF devices
should purge the oldest records first.
o 'smfNhdpRssaMesgTLVIncluded' - this writable configuration object
indicates whether the associated NHDP messages include the the
RSSA Message TLV, or not. It is highly RECOMMENDED that this
object be set to 'true(1)'.
o 'smfNhdpRssaAddrBlockTLVIncluded' - this writable configuration
object indicates whether the associated NHDP messages include the
the RSSA Address Block TLV, or not. The
smfNhdpRssaAddrBlockTLVIncluded is optional in all cases as it
depends on the existence of an address block which may not be
present. If this SMF device is configured with NHDP, then this
object should be set to 'true(1)'.
o 'smfConfiguredAddrForwardingTable' - the writable configuration
objects in this table indicate which multicast IP address are to
be forwarded by this SMF node. Misconfiguration of rows within
this table can limit the ability of this SMF device to forward
multicast data.
o 'smfInterfaceTable' - 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 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
that this SMF node is part of the CDS, or not. Being part of the
CDS makes this node a distinguished device. It could be exploited
for data ex-filtration, or denial of service attacks.
Cole, et al. Expires April 4, 2012 [Page 50]
Internet-Draft The SMF MIB October 2011
o 'smfDiscoveredAddrForwardingTable' - the readable state objects in
this table indicate which, dynamically discovered, multicast IP
address are to be forwarded by this SMF node.
o 'smfNeighborTable' - 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 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
pose 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.
It is RECOMMENDED that implementers consider the security features as
provided by the SNMPv3 framework (see [RFC3410], section 8),
including full support for the SNMPv3 cryptographic mechanisms (for
authentication and privacy).
Further, deployment of SNMP versions prior to SNMPv3 is NOT
RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to
enable cryptographic security. It is then a customer/operator
responsibility to ensure that the SNMP entity giving access to an
instance of this MIB module is properly configured to give access to
the objects only to those principals (users) that have legitimate
rights to indeed GET or SET (change/create/delete) them.
9. IANA Considerations
Editor's Note (to be removed prior to publication): the IANA is
requested to assign a value for "XXXX" under the 'experimental'
subtree and to record the assignment in the SMI Numbers registry.
When the assignment has been made, the RFC Editor is asked to replace
"XXXX" (here and in the MIB module) with the assigned value and to
remove this note. Note well: prior to official assignment by the
IANA, a draft document MUST use placeholders (such as "XXXX" above)
rather than actual numbers. See RFC4181 Section 4.5 for an example
of how this is done in a draft MIB module.

Appendix A. Change Log
This section tracks the revision history in the development of this
SMF-MIB. It will be removed from the final version of this document.
These changes were made from draft-ietf-manet-smf-mib-02 to
draft-ietf-manet-smf-mib-03.
1. Clarified and added discussion of default values for several of
the configuration objects within the MIB.
2. Added the security section.
These changes were made from draft-ietf-manet-smf-mib-01 to
draft-ietf-manet-smf-mib-02.
1. Added the NotificationGroup to the MIB and updated the
ConformanceGroup.
2. Added the definition of an smfRouterID to the MIB. This is later
used in the Notifications to indicate the origin of the event to
the management station.
3. Removed the Router Priority object as this was used only in the
eCDS algorithm and hence should be contained within the future
eCDS-MIB.
4. Cleaned up the TEXTUAL CONVENTION for the `SmfOpMode'.
5. Filled in some of the missing text in various object
descriptions.
These changes were made from draft-ietf-manet-smf-mib-00 to
draft-ietf-manet-dsmf-mib-01.
1. Editorial changes to the textual material. These included the
addition of the paragraphs on TEXTUAL-CONVENTIONS defined and
imported into this MIB and relationships to other MIBs.
2. Identified those objects in the SMF-MIB requiring non-volatile
storage.
Cole, et al. Expires April 4, 2012 [Page 53]
Internet-Draft The SMF MIB October 2011
3. Changed the name of the TEXTUAL-CONVENTION 'Status', defined
within this MIB to 'SmfStatus'.
Appendix B. Open Issues
This section contains the set of open issues related to the
development and design of the SMF-MIB. This section will not be
present in the final version of the MIB and will be removed once all
the open issues have been resolved.
1. A careful review by the working group.
