Network Working Group O. Nicklass, Ed. Request for Comments: 4805 RAD Data Communications, Ltd. Obsoletes: 3895 March 2007 Category: Standards Track Definitions of Managed Objects for the DS1, J1, E1, DS2, and E2 Interface Types 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. Copyright Notice Copyright (C) The IETF Trust (2007). 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 objects used for managing DS1, J1, E1, DS2, and E2 interfaces. This document is a companion to the documents that define managed objects for the DS0, DS3/E3, and Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH) Interface Types. This document obsoletes RFC 3895. Nicklass, Ed. Standards Track [Page 1] RFC 4805 DS1/J1/E1/DS2/E2 MIB March 2007 Table of Contents 1.

The Internet-Standard Management Framework For a detailed overview of the documents that describe the current Internet-Standard Management Framework, please refer to section 7 of RFC 3410 [RFC3410]. Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. MIB objects are generally accessed through the Simple Network Management Protocol (SNMP). Objects in the MIB are defined using the mechanisms defined in the Structure of Management Information (SMI). This memo specifies a MIB module that is compliant to the SMIv2, which is described in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580 [RFC2580]. Nicklass, Ed.

Conventions Used in This Document The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119]. 3. Overview These objects are used when the particular media being used to realize an interface is a DS1/J1/E1/DS2/E2 interface. At present, this applies to the following value of the ifType variable in theShow full document text
