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.

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.

RFC 2417 Multicast MIB September 1998
2.1. The MARS Client Group

4. Acknowledgments
This document is a product of the IETF's Internetworking Over NBMA
Networks (ion) Working Group. The original work of the MARS MIB
developement was sponsored by Science Applications International
Corporation (SAIC).
The author would like to recognize Grenville Armitage (Bellcore), Ken
Carlberg (SAIC), Ramesh Uppuluri (Fore Systems), and Radha Gowda
SYNNET), and Bill Willcox (Fujitsu Nexion) for their support and
comments in completing the MARS MIB. Also thanks to Bert Wijnen (IBM)
for his thorough review of the MARS MIB.

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.
