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

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

This memo does not specify a standard for the Internet community

1. The SNMP Network Management

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

o the SMI, described in RFC 1902 [2] - the mechanisms used
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]
SNMPv2.

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

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

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

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

1.1. Object

Managed objects are accessed via a virtual information store,
the Management Information Base or MIB. Objects in the MIB
defined using the subset of Abstract Syntax Notation One (ASN.1)
defined in the SMI. In particular, each object type is named by
OBJECT IDENTIFIER, an administratively assigned name. The
type together with an object instance serves to uniquely identify
specific instantiation of the object. For human convenience,
often use a textual string, termed the descriptor, to also refer
the object type

RFC 2366 Multicast MIB July 1998

2.

This MARS MIB is designed to define managed objects that can be
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
system where one or more MARS clients are running, or where one
more MARS servers are running, or where one or more MARS
servers are running

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

Multicast

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

Multicast Address Resolution Server (MARS

A server that distributes multicast group membership information
endpoints

Client/

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

The set of clients managed by a MARS

Multicast Server (MCS

A server that sets up ATM Virtual Channels (VCs) between endpoints
a multicast group and to which the endpoints forward data traffic
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

2.3. The MARS Multicast Server

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

This group contains the following tables

o MARS Multicast Server

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