Internet-Draft The SMF MIB July 2008 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]. SMF provides multicast duplicate packet detection (DPD) and supports algorithms for constructing an estimate of a mobile ad hoc network (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 management stations 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 CDS-based relay sets. 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. Various algorithms for the construction of estimates of the MCDS exist. The Simplified Multicast Framework [I-D.ietf-manet-smf] Cole, et al. Expires January 8, 2009 [Page 3]
Internet-Draft The SMF MIB July 2008 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 routers' 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.

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. Cole, et al. Expires January 8, 2009 [Page 5]
Internet-Draft The SMF MIB July 2008 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. o smfMIBObjects - defines the objects forming the basis for the SMF MIB. These objects are divided up by function into the following groups: * 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 used in the SMF MIB are as follows. The RowStatus textual convention is imported from RFC 2579 [RFC2579]. 5.2. The Configuration Group The SMF device is configured with a set of controls. The list of 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 Cole, et al. Expires January 8, 2009 [Page 6]
Internet-Draft The SMF MIB July 2008 o NHDP RSSA Message TLV - if NHDP mode is selected, then is the RSSA Message TLV included in the NHDP exchanges. (Question: Is this and the following two TLVs optional and are they included as a group or independently of one another?) o NHDP RSSA Address Block TLV - if NHDP mode is selected, then is the RSSA Address Block TLV included in the NHDP exchanges. o Router Priority TLV - if NHDP mode is selected, then is the Router Priority TLV included in the NHDP exchanges. 5.3. The State Group The State Subtree reports current state information. 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. 5.4. 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: (Note: Need to have a discussion of the important and measurable events related to SMF RSSA multicast performance.) (Note: Do we need to break these out by type, i.e., v4 versus v6?) 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 5.5. The Notifications Group The Notifications Subtree contains the list of notifications supported within the SMF-MIB and their intended purpose or utility. This group is currently empty. Cole, et al.

Internet-Draft The SMF MIB July 2008 6. Relationship to Other MIB Modules [TODO]: The text of this section specifies the relationship of the MIB modules contained in this document to other standards, particularly to standards containing other MIB modules. Definitions imported from other MIB modules and other MIB modules that SHOULD be implemented in conjunction with the MIB module contained within this document are identified in this section. 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. Relationship to the IF-MIB [TODO] This section is included as an example; If the MIB module is not an adjunct of the Interface MIB, then this section should be removed. 6.3. MIB modules required for IMPORTS [TODO]: Citations are not permitted within a MIB module, but any module mentioned in an IMPORTS clause or document mentioned in a REFERENCE clause is a Normative reference, and must be cited someplace within the narrative sections. If there are imported items in the MIB module, such as Textual Conventions, that are not already cited, they can be cited in text here. Since relationships to other MIB modules should be described in the narrative text, this section is typically used to cite modules from which Textual Conventions are imported. The following SMF-MIB module IMPORTS objects from SNMPv2-SMI [RFC2578], SNMPv2-TC [RFC2579], SNMPv2-CONF [RFC2580], and IF-MIB [RFC2863] 7.

Security Considerations [TODO] Each specification that defines one or more MIB modules MUST contain a section that discusses security considerations relevant to those modules. This section MUST be patterned after the latest approved template (available at http://www.ops.ietf.org/mib-security.html). Remember that the objective is not to blindly copy text from the template, but rather to think and evaluate the risks/vulnerabilities and then state/ document the result of this evaluation. [TODO] if you have any read-write and/or read-create objects, please include the following boilerplate paragraph. 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 [TODO] writeable MIB objects that could be especially disruptive if abused MUST be explicitly listed by name and the associated security risks MUST be spelled out; RFC 2669 has a very good example. Cole, et al. Expires January 8, 2009 [Page 19]
Internet-Draft The SMF MIB July 2008 o [TODO] list the writable tables and objects and state why they are sensitive. [TODO] else if there are no read-write objects in your MIB module, use the following boilerplate paragraph. 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 this MIB module is implemented correctly, then there is no risk that an intruder can alter or create any management objects of this MIB module via direct SNMP SET operations. [TODO] if you have any sensitive readable objects, please include the following boilerplate paragraph. 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 [TODO] you must explicitly list by name any readable objects that are sensitive or vulnerable and the associated security risks MUST be spelled out (for instance, if they might reveal customer information or violate personal privacy laws such as those of the European Union if exposed to unauthorized parties) o [TODO] list the tables and objects and state why they are sensitive. [TODO] discuss what security the protocol used to carry the information should have. The following three boilerplate paragraphs should not be changed without very good reason. Changes will almost certainly require justification during IESG review. 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). Cole, et al. Expires January 8, 2009 [Page 20]
Internet-Draft The SMF MIB July 2008 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 [TODO] In order to comply with IESG policy as set forth in http://www.ietf.org/ID-Checklist.html, every Internet-Draft that is submitted to the IESG for publication MUST contain an IANA Considerations section. The requirements for this section vary depending what actions are required of the IANA. see RFC4181 section 3.5 for more information on writing an IANA clause for a MIB module document. [TODO] select an option and provide the necessary details. Option #1: The MIB module in this document uses the following IANA-assigned OBJECT IDENTIFIER values recorded in the SMI Numbers registry: Descriptor OBJECT IDENTIFIER value ---------- ----------------------- sampleMIB { mib-2 XXX } Option #2: Editor's Note (to be removed prior to publication): the IANA is requested to assign a value for "XXX" under the 'mib-2' subtree and to record the assignment in the SMI Numbers registry. When the assignment has been made, the RFC Editor is asked to replace "XXX" (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 "XXX" above) rather than actual numbers. See RFC4181 Section 4.5 for an example of how this is done in a draft MIB module. Option #3: This memo includes no request to IANA. Cole, et al. Expires January 8, 2009 [Page 21]
