Document Information

• RFC Number: 1157
• Title: A Simple Network Management Protocol (SNMP)

Abstract

This memo defines a simple protocol by which management information for a network element may be inspected or altered by logically remote users. Together with the companion memos describing the structure of management information and the management information base, it provides a simple, workable architecture and system for managing TCP/IP-based internets. This memo is a re-release of RFC 1098.
