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) [RFC6621] 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.
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", "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 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.
Various algorithms for the construction of estimates of the MCDS exist. The Simplified Multicast Framework [RFC6621] 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.
4.1. SMF Management Model
-
This section describes the management model for the SMF node process.
Figure 1 (reproduced from Figure 1 of [RFC6621]) 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.
______________ ____________ | | | | | Neighborhood | | Relay Set | | Discovery |------------->| Selection | | | neighbor | | |______________| info |____________| \ / neighbor\ / forwarding info* \ _____________ / status \ | | / `-->| Forwarding |<--' | Process | ----------------->|_____________|-----------------> incoming packet, forwarded packets interface id*, and previous hop*-

4.2. Terms
-
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.
5. Structure of the MIB Module
-
This section presents the structure of the SMF-MIB module. The objects are arranged into the following groups:
- smfMIBNotifications - defines the notifications associated with the SMF process.
- 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.
5.1. Textual Conventions
-
The Textual Conventions defined within the SMF-MIB module:
- 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:
- The IANAsmfOpModeIdTC represents an index that identifies a specific SMF operational mode. This Textual Convention is maintained by IANA in the IANA-SMF-MIB.
- 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.
5.2. The Capabilities Group
-
The SMF device supports a set of capabilities. The list of capabilities that the device can advertise is as follows:
- Operational Mode - topology information from NHDP, CDS-aware unicast routing, or Cross-layer from Layer 2.
- 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.
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 are:
- Operational Mode - determines from where topology information is derived, e.g., NHDP, CDS-aware unicast routing, or Cross-layer from Layer 2.
- SMF RSSA - the specific RSSA operational on the device.
- Duplicate Packet detection for IPv4 - Identification-based or Hash-based DPD (I-DPD or H-DPD, respectively).
- Duplicate Packet detection for IPv6 - Identification-based or Hash-based DPD.
- SMF Type Message TLV - if NHDP mode is selected, then the SMF Type Message TLV MAY be included in the NHDP exchanges.
- SMF Address Block TLV - if NHDP mode is selected, then the SMF Address Block TLV SHOULD be included in the NHDP exchanges.
- SMF Address Forwarding Table - a table identifying configured multicast addresses to be forwarded by the SMF process.
5.4. The State Group
-
The State sub-tree reports current state information, for example,
- Node RSSA State - identifies whether the node is currently in or out of the Relay Set.
- Neighbors Table - a table containing current one-hop neighbors and their operational RSSA.
5.5. The Performance Group
-
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:
- Total multicast packets received.
- Total multicast packets forwarded.
- Total duplicate multicast packets detected.
- Per interface statistics table with the following entries:
-
- Multicast packets received.
- Multicast packets forwarded.
- Duplicate multicast packets detected.
5.6. The Notifications Group
-
The Notifications sub-tree contains the list of notifications supported within the SMF-MIB module and their intended purpose and utility.
5.7. Tables and Indexing
-
The SMF-MIB module contains a number of tables that record data related to:
- configuration and operation of packet forwarding on the local router,
- configuration and operation of local MANET interfaces on the router, and
- configuration and operation of various RSSAs for packet forwarding.
The SMF-MIB module's tables are indexed via the following constructs:
- smfCapabilitiesIndex - the index identifying the combination of SMF mode and SMF RSSA available on this device.
- smfCfgAddrForwardingIndex - the index to configured multicast address lists that are forwarded by the SMF process.
- smfCfgIfIndex - the IfIndex of the interface on the local router on which SMF is configured.
- 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:
- smfCapabilitiesTable - identifies the resident set of (SMF Operational Modes, SMF RSSA algorithms) available on this router. This table has 'INDEX { smfCapabilitiesIndex }'.
- smfCfgAddrForwardingTable - contains information on multicast addresses that are to be forwarded by the SMF process on this device. This table has 'INDEX { smfCfgAddrForwardingIndex }'.
- smfCfgInterfaceTable - describes the SMF interfaces on this device that are participating in the SMF packet forwarding process. This table has 'INDEX { smfCfgIfIndex }'.
- 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 }'.
- smfPerfIpv4InterfacePerfTable - contains the IPv4-related SMF statistics per each SMF interface on this device. This table has 'INDEX { smfCfgIfIndex }'.
- smfPerfIpv6InterfacePerfTable - contains the IPv6-related SMF statistics per each SMF interface on this device. This table has 'INDEX { smfCfgIfIndex }'.
6. Relationship to Other MIB Modules
6.1. Relationship to the SNMPv2-MIB
-
The 'system' group in the SNMPv2-MIB module [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 module does not duplicate those objects.
6.2. Relationship to the IP-MIB
-
It is an expectation that SMF devices will implement the standard IP- MIB module [RFC4293]. Exactly how to integrate SMF packet handling and management into the standard IP-MIB module management are part of 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.
6.3. Relationship to the IPMCAST-MIB
-
The smfCfgAddrForwardingTable is essentially a filter table (if populated) that identifies addresses/packets to be forwarded via the local SMF flooding process. The IP Multicast MIB module in RFC 5132 [RFC5132] manages objects related to standard IP multicast, which could be running in parallel to SMF on the device.
RFC 5132 manages traditional IP-based multicast (based upon multicast routing mechanisms). The SMF-MIB module provides management for a MANET subnet-based flooding mechanism which, 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.
6.4. MIB Modules Required for IMPORTS
-
The objects imported for use in the SMF-MIB module are as follows. The MODULE-IDENTITY, OBJECT-TYPE, NOTIFICATION-TYPE, Counter32, Integer32, TimeTicks and experimental macros are imported from RFC 2578 [RFC2578]. The TEXTUAL-CONVENTION, RowStatus, and TruthValue macros are imported from RFC 2579 [RFC2579]. The MODULE-COMPLIANCE, OBJECT-GROUP, and NOTIFICATION-GROUP macros are imported from RFC 2580 [RFC2580]. The InterfaceIndexOrZero and ifName textual conventions are 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].
6.5. Relationship to Future RSSA-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 the set of supported RSSAs.

The IP Multicast MIB module in RFC 5132 manages objects related to standard IP multicast, which could be running in parallel to SMF on the device.-
-
RFC 5132 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 ifIndex is from the interfaces group defined in the Interfaces Group MIB module (RFC 2863). As such, this table 'sparse augments' the ifTable specifically when SMF is to be configured to 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
-
-
-
automatically defined by the agent with these 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.

corresponding entry (if it exists) in the

-
-
- 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

8. IANA-SMF-MIB Definitions
-
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 [RFC5742]). 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.
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 [RFC5742]). The category of RFC MUST be Experimental. The RSSA algorithms MUST be documented in sufficient detail so that interoperability between independent implementations is possible.

9. 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:
- '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.
- '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.
- '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.
- '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.
- '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.
- '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 [RFC6621]. However, it is RECOMMENDED that a deployment be configured with a common mode for operational consistency.
- '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.
- '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.
- '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.
- '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.
- '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.
- '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.
- '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:
- '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.
- '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 [RFC3410]), and implementations claiming compliance to the SNMPv3 standard MUST include full support for authentication and privacy via the User-based Security Model (USM) [RFC3414] with the AES cipher algorithm [RFC3826]. Implementations MAY also provide support for the Transport Security Model (TSM) [RFC5591] in combination with a secure transport such as SSH [RFC5592] or TLS/DTLS [RFC6353].
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.
10. Applicability Statement
-
This document describes objects for configuring parameters of the Simplified Multicast Forwarding [RFC6621] 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 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:
- 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.
- 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.
- 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
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.
11. IANA Considerations
-
This document defines two MIB modules:
- SMF-MIB is defined in Section 7 and is an experimental MIB module.
- IANA-SMF-MIB is defined in Section 8 and is an IANA MIB module that IANA maintains.
Thus, IANA has completed three actions:
IANA has allocated an OBJECT IDENTIFIER value and recorded it in the SMI Numbers registry in the subregistry called "SMI Experimental Codes" under the experimental branch (1.3.6.1.3).
Decimal | Name | Description | Reference
