Status of this Memo

  This document specifies an Internet standards track protocol for the

  Official Protocol Standards" (STD 1) for the standardization state
  and status of this protocol.  Distribution of this memo is unlimited.

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 managed objects for IP hosts and routers
  that use a Multicast Address Resolution Server (MARS) to support IP
  multicast over ATM, as described in 'Support for Multicast over UNI
  3.0/3.1 based ATM Networks' [1].

  This memo specifies a MIB module in a manner that is both compliant
  to the SNMPv2 SMI, and semantically identical to the peer SNMPv1
  definitions.

1.  The SNMP Network Management Framework

  The SNMP Network Management Framework presently consists of these
  components.  They are:

  o    the SMI, described in RFC 1902 [2] - the mechanisms used for
       describing and naming objects for the purpose of management.

  o    the Textual Conventions, described in RFC 1903 [3] for SNMPv2.

  o    the Conformance Statements, described in RFC 1904 [4] for
       SNMPv2.

  o    the Simple Network Management Protocol, described in
       STD 15, RFC 1157 [5].

  o    the Protocol Operations, described in RFC 1905 [6] for
       SNMPv2.

  o    the MIB-II, STD 17, RFC 1213 [7] - the core set of managed
       objects for the Internet suite of protocols for SNMPv2.

  The Framework permits new objects to be defined for the purpose of
  experimentation and evaluation.

1.1.  Object Definitions

  Managed objects are accessed via a virtual information store, termed
  the Management Information Base or MIB.  Objects in the MIB are
  defined using the subset of Abstract Syntax Notation One (ASN.1)
  defined in the SMI.  In particular, each object type is named by an
  OBJECT IDENTIFIER, an administratively assigned name.  The object



Chung & Greene              Standards Track                     [Page 2]

RFC 2417                     Multicast MIB                September 1998


  type together with an object instance serves to uniquely identify a
  specific instantiation of the object.  For human convenience, we
  often use a textual string, termed the descriptor, to also refer to
  the object type.

2.  Overview

  This MARS MIB is designed to define managed objects that can be used
  to manage the MARS clients, servers, and the multicast servers (MCS),
  as described in the RFC2022[1].  The MIB is supposed to be used on a
  system where one or more MARS clients are running, or where one or
  more MARS servers are running, or where one or more MARS multicast
  servers are running.

  An understanding of MARS, as defined in [1] is assumed in this MIB
  module definition. However, the following terms are used frequently
  and are included here for reference:

  Multicast Group

  A group of endpoints that communicate with each other such that
  packets sent from one endpoint are received by all other members of
  the multicast group.

  Multicast Address Resolution Server (MARS)

  A server that distributes multicast group membership information to
  endpoints.

  Client/Endpoint

  An ATM-attached host or router that registers with a MARS and that is
  a member of one or more multicast groups. An endpoint may establish
  ATM Virtual Channels (VCs) to the other group members or may make use
  of a Multicast Server.

  Cluster

  The set of clients managed by a MARS.

  Multicast Server (MCS)

  A server that sets up ATM Virtual Channels (VCs) between endpoints in
  a multicast group and to which the endpoints forward data traffic for
  transmission on their behalf.

  The MIB is broken down into three major groups: a MARS client group,
  MARS (server) group, and MARS Multicast Server (MCS) Group.

2.1.  The MARS Client Group

  This client group defines a collection of objects required to be
  implemented in a MIB for the management of MARS clients. It contains
  the following tables:

  A list of backup MARS's associated with a MARS client.

  o    MARS Client VC Table

  Information about VCs opened by a client.

  o    MARS Client Statistics Table

  Statistics collected by a MARS client.

2.2.  The MARS Server Group

  This MARS server group defines a collection of objects required to be
  implemented in a MIB for the management of MARS servers.  It contains
  the following tables:

  o    MARS Table

  Information about a MARS such as its ATM address, its status and
  timers.

  o    MARS Multicast Group Table

  A list of IP multicast address blocks associated with a MARS.

2.3.  The MARS Multicast Server Group

  This MARS multicast server group defines a collection of objects
  required to be implemented in a MIB for the management of MARS
  multicast servers. It contains the following tables:

  This group contains the following tables:

  o    MARS Multicast Server Table

  Information about a MCS, such as its ATM address, default MARS ATM
  address, and registration state.

  o    MARS MCS Multicast Group Table

  A list of IP multicast address blocks associated with a MARS MCS.

  o    MARS MCS Backup Mars Group Table

           circuit, each entry represents a single VC connection
           between this client ATM address to another party ATM
           address.  In the case of point to multipoint connection
           where a single source address is associated with
           multiple destinations, several entries are used to
           represent the relationship.  An example of point to
           multi-point VC represented in a table is shown below.

                  Client    VPI/VCI    Grp Addr1/Addr2    Part Addr

           Note:  This table assumes the IP multicast address
                  groups (min, max) defined in each entry are
                  always consecutive.  In the case of that a
                  client receives a JOIN/LEAVE with

6.  Security Considerations

  There are a number of management objects defined in this MIB that
  have a MAX-ACCESS clause of read-write and/or read-create. Such
  object 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.

  SNMPv1 by itself is such an insecure environment. 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 SET
  (change/create/delete) the objects in this MIB.

  It is recommended that the implementers consider the security
  features as provided by the SNMPv3 framework. Specifically, the use
  of the User-based Security Model RFC 2274 [8] and the View-based
  Access Control Model RFC 2275 [9] is recommended.

  It is then a customer/user responsibility to ensure that the SNMP
  entity giving access to this MIB, is properly configured to give
  access to those objects only to those principals (users) that have a
  legitimate rights to indeed SET (change/create/delete) them.

  Note: read-access in fact may also need access-control.
