Definitions of Managed Objects for Multicast over UNI 3.0/3.1 based ATM Networks


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 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.

RFC 2417                     Multicast MIB                September 1998

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.

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.

Deletion of this row is allowed regardless of whether or not a row in any associated tables (i.e., marsClientVcTable) still exists or is in use.

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.
