                 Definitions of Managed Objects for
           Multicast over UNI 3.0/3.1 based ATM Networks

Status of this Memo

 This document specifies an Internet standards track protocol for the
 Internet community, and requests discussion and suggestions for
 improvements.  Please refer to the current edition of the "Internet
 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.
 This memo does not specify a standard for the Internet community.

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
      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
 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.

Chung & Greene Standards Track [Page 2] RFC 2366 Multicast MIB July 1998

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.

Chung & Greene Standards Track [Page 3] RFC 2366 Multicast MIB July 1998

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:
 o    MARS Client Table
 Information about a client such as its ATM address, the ATM address
 of its default MARS, registration status, and timers.
 o    MARS Client Multicast Group Table
 A list of IP multicast address blocks associated with a MARS client.
 o    MARS Client Backup MARS Group Table
 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.
 o    MARS VC Table
 Information about VCs opened by a MARS.
 o    MARS Registered Client Table

Chung & Greene Standards Track [Page 4] RFC 2366 Multicast MIB July 1998

 A list of clients registered with a MARS.
 o    MARS Registered Multicast Server Table
 A list of MCSs registered with a MARS.
 o    MARS Statistics Table
 Statistics collected by a MARS.
 o    MARS Host Map Table
 Mappings between multicast groups and clients maintained by a MARS.
 o    MARS Server Map Table
 Mappings between multicast groups and MCSs maintained by 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
 A list of backup MARS's associated with a MARS MCS.
 o    MARS Multicast Server VC Table
 Information about VCs opened by a MCS.
 o    MARS Multicast Server Statistics Table
 Statistics collected by a MCS.

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.

Chung & Greene Standards Track [Page 74] RFC 2366 Multicast MIB July 1998

 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.
