Network Working Group C. Brown Request for Comments: 2115 Cadia Networks, Inc. Obsoletes: 1315 F. Baker Category: Standards Track Cisco Systems September 1997 Management Information Base for Frame Relay DTEs Using SMIv2 1. 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. 2. 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 Frame Relay interfaces on DTEs.

The SNMPv2 Network Management Framework The major components of the SNMPv2 Network Management framework are described in the documents listed below. o RFC 1902 [1] defines the Structure of Management Information (SMI), the mechanisms used for describing and naming objects for the purpose of management. o STD 17, RFC 1213 [2] defines MIB-II, the core set of managed objects (MO) for the Internet suite of protocols. o RFC 1905 [3] defines the protocol used for network access to managed objects. The framework is adaptable/extensible by defining new MIBs to suit the requirements of specific applications/protocols/situations. Managed objects are accessed via a virtual information store, the 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, which is 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, often a textual string, termed the descriptor, is used to refer to the object type. 4. Overview 4.1. Frame Relay Operational Model For the purposes of understanding this document, Frame Relay is viewed as a multi-access media, not as a group of point- to-point connections. This model proposes that Frame Relay is a single interface to the network (physical connection) with many destinations or neighbors (virtual connections). This view enables a network manager the ability to group all virtual connections with their corresponding physical connection thereby allowing simpler diagnostics and trouble shooting. With the extension of the interfaces MIB, it is possible to configure frame relay DLCs as individual interfaces and create ifTable entries for each. This is not recommended and is not directly supported by this MIB. Additionally, in the presence of demand circuits creation of individual ifEntries for each is not possible. Brown & Baker Standards Track [Page 2] RFC 2115 Frame Relay DTE MIB September 1997 Should the user wish to group DLCs together to associate them with a higher layer, or to associate a DLC with an unnumbered point-to-point service, the frame relay DTE MIB provides an entry in the frCircuitEntry record. For example, suppose one were to configure a company proprietary protocol to run above several of the frame relayShow full document text
