INTERNET-DRAFT MARS MIB November 1997 Abstract This memo defines an experimental 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 three major 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 MIB-II, STD 17, RFC 1213 [3] - the core set of managed objects for the Internet suite of protocols. o the protocol, RFC 1157 [4] and/or RFC 1905 [5], - the protocol for accessing managed objects. 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. Expires May 1998 [Page 2]
INTERNET-DRAFT MARS MIB November 1997 2. Overview 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 group 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 Expires May 1998 [Page 3]
INTERNET-DRAFT MARS MIB November 1997 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 group 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 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 Expires May 1998 [Page 4]
INTERNET-DRAFT MARS MIB November 1997 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 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.
