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.

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. Chung & Greene Standards Track [Page 3]
RFC 2417 Multicast MIB September 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 2417 Multicast MIB September 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.

RFC 2417 Multicast MIB September 1998 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. 7.
