INTERNET-DRAFT                  MARS MIB                     August 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.

INTERNET-DRAFT                  MARS MIB                     August 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

   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

   o    MARS VC Table

   Information about VCs opened by a MARS.


   o    MARS Registered Client Table

   o    MARS Registered Multicast Server Table

   A list of MCSs registered with a MARS.


   o    MARS Statistics Table

   address, and registration state.

8.  Changes since version 01

(Note: this section will be removed when the document becomes an RFC.)

The following changes have been made to the MIB:

1) Add AdEntAddr as an index to ipAtmMarsClientEntry
   in associating an IP address with an ATM address of a client

2) Add ifIndex field in the IpAtmMarsEntry and IpAtmMarsMcsEntry
   to associate an interface with a MARS and MCS.

3) Add statistcs for GroupListRequest and GroupListResponses for
   MARS clients.

4) Add a configurable idle timer (inactivity) timer for MARS client
   and MCS.

5) Add all configurable timers currently defined in IpAtmMarsClientEntry
   to ipAtmMarsMcsEntry.

6) Add a list of configurable backup MARS's for a client & MCS to
   contact in case of primary MARS fails.

7) Update the comments for ipAtmMarsMcsMcGrpEntry to relect that
   MCS does not support block joins
