McCloghrie Hughes LAN Systems, Inc. July 1993 Definitions of Managed Objects for Bridges Status of this Memo This RFC specifies an IAB standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "IAB Official Protocol Standards" 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 TCP/IP based internets. In particular it defines objects for managing MAC bridges based on the IEEE 802.1D-1990 standard between Local Area Network (LAN) segments. Provisions are made for support of transparent bridging. Provisions are also made so that these objects apply to bridges connected by subnetworks other than LAN segments. Table of Contents 1. The Network Management Framework ...................... 2 2.

Authors' Addresses .................................... 34 1. The Network Management Framework The Internet-standard Network Management Framework consists of three components. They are: STD16/RFC 1155 which defines the SMI, the mechanisms used for describing and naming objects for the purpose of management. STD16/RFC 1212 defines a more concise description mechanism, which is wholly consistent with the SMI. RFC 1156 which defines MIB-I, the core set of managed objects for the Internet suite of protocols. STD17/RFC 1213, defines MIB-II, an evolution of MIB-I based on implementation experience and new operational requirements. STD15/RFC 1157 which defines the SNMP, the protocol used for network access to managed objects. The Framework permits new objects to be defined for the purpose of experimentation and evaluation. 2. Objects 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) [7] defined in the SMI. In particular, each object is named by an OBJECT IDENTIFIER, an administratively assigned name, which specifies an object type. 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. Decker, Langille, Rijsinghani & McCloghrie [Page 2]Show full document text
