Abstract

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 the Simplified Multicast Forwarding (SMF) process for Mobile Ad-Hoc Networks (MANETs). The SMF-MIB also reports state information, performance metrics, and notifications. In addition to configuration, the additional state and performance information is useful to operators troubleshooting multicast forwarding problems.

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 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.

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 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 [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 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:

5. Structure of the MIB Module

This section presents the structure of the SMF-MIB module. The objects are arranged into the following groups:

5.1. Textual Conventions

The textual conventions defined within the SMF-MIB are as follows:

5.2. The Capabilities Group

The SMF device supports a set of capabilities. The list of capabilities which the device can advertise are:

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:

5.4. The State Group

The State sub-tree reports current state information, e.g.,

5.5. The Performance Group

The Performance sub-tree reports primarily counters that relate to SMF RSSA performance. The SMF performance counters consists of per node and per interface objects:

5.6. The Notifications Group

The Notifications Sub-tree contains the list of notifications supported within the SMF-MIB and their intended purpose or utility.

5.7. Tables and Indexing

The SMF-MIB module contains a number of tables which record data related to:

The SMF-MIB module's tables are indexed via the following constructs:

These tables and their indexing are:

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.

           "An index that identifies through reference to a specific

            of SMF operation with reduced relay sets: 

              Independent operation - SMF performs its own relay
                  set selection using information from an associated 
                  MANET NHDP process.

              CDS-aware unicast routing operation - a coexistent 
                  unicast routing protocol provides dynamic relay 
                  set state based upon its own control plane 
                  CDS or neighborhood discovery information.

              Cross-layer operation -  SMF operates using
                  neighborhood status and triggers from a 
                  cross-layer information base for dynamic relay 
                  set selection and maintenance."

         "The SMF Interface Table describes the SMF
          interfaces that are participating in the 
          SMF packet forwarding process. The ifIndex is 
          from the interfaces group defined in the 
          Interfaces Group MIB (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 supports and runs SMF.

          The manager can create a row by setting
          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.

          If the corresponding entry with ifIndex value
          is deleted from the Interface Table, then the entry
          in this table is automatically deleted and
          SMF is disabled on this interface,

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:

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:

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.

Implementations MUST provide the security features described by the SNMPv3 framework (see [RFC3410] ), including 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.

9. Applicability Statement

This document describes objects for configuring parameters of the Simplified Multicast Forwarding [RFC6621] process on a router. This MIB module, denoted SMF-MIB, also reports state, performance information and notifications. This sections 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 will be provided elsewhere.

SMF is designed to allow 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 are estimated using the RSSAs discussed within this document. In the following, three scenarios are listed where this MIB module is useful, i.e.,

10. IANA Considerations

The MIB module in this document uses the following IANA-assigned OBJECT IDENTIFIER value recorded in the SMI Numbers registry:

      Descriptor        OBJECT IDENTIFIER value
      ----------        -----------------------
      SMF-MIB          { experimental XXXX }
      IANA EDITOR NOTE: please assign XXXX
        

11. Contributors

This MIB document uses the template authored by D. Harrington which is based on contributions from the MIB Doctors, especially Juergen Schoenwaelder, Dave Perkins, C.M.Heard and Randy Presuhn.

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-04 to draft-ietf-manet-smf-mib-05.

  1. Updated the smfInterfaceTable to reflect that fact that we want it to 'sparsely augment' the ifTable.
  2. Added a section to the text discussing the SMF Tables and their indexing.
  3. Added the section on 'Applicability Statement'.
  4. Added/checked for DEFVAL, REFERENCES, UNITS and SIZE clauses within the MIB.

These changes were made from draft-ietf-manet-smf-mib-03 to draft-ietf-manet-smf-mib-04.

  1. Removed the bitmap switch in the notifications control group.
  2. Moved the notification Objects group up to support reverse-mapping between SNMPv1 traps and SNMPv2 notifications.
  3. Removed reference to the notifications state group.
  4. Replaced smfIfIndex with smfIfName in notifications.

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.
  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.
