Introduction 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 used for managing Network Interfaces. This memo discusses the 'interfaces' group of MIB-II, especially the experience gained from the definition of numerous media-specific MIB modules for use in conjunction with the 'interfaces' group for managing various sub-layers beneath the internetwork-layer. It proposes clarifications to, and extensions of, the architectural issues within the current model used for the 'interfaces' group. This memo also includes a MIB module. As well as including new MIB definitions to support the architectural extensions, this MIB module also re-specifies the 'interfaces' group of MIB-II in a manner which is both compliant to the SNMPv2 SMI and semantically-identical to the existing SNMPv1-based definitions. 2. The SNMPv2 Network Management Framework The SNMPv2 Network Management Framework consists of four major components. They are: o RFC 1442 which defines the SMI, the mechanisms used for describing and naming objects for the purpose of management. o STD 17, RFC 1213 defines MIB-II, the core set of managed objects for the Internet suite of protocols. o RFC 1445 which defines the administrative and otherShow full document text
