Presents a concise, focused & practical guide to SNMP-based network & internetwork management for network administrators, managers, & designers. Equips you to better determine your network management needs, gain insight into design issues, & obtain the necessary understanding to evaluate available SNMP-based products. DLC: Computer networks - Management. The Simple Network Management Protocol (SNMP) and the related Remote Network Monitoring (RMON) standards make it possible for network administrators to control and monitor even the most complicated networks. In a textbook-style treatment, William Stallings's SNMP, SNMPv2, SNMPv3, and RMON 1 and 2 explains what's behind this family of popular networking standards. The book begins with some theory about what tasks network administrators need to do, such as monitoring performance, faults, and accounting, along with configuration and security control. The guide then describes SNMP--which was introduced in 1989--as a successful solution to the basic problems of network administration. (One of the strengths of SNMP is that it allows administrators to work with disparate networks running on TCP/IP.) The author details how an SNMP Management Information Base (MIB), which stores network information, is organized and also how the protocol works to collect and store network information. The RMON standard actually uses SNMP with its own MIB format to collect statistics about a network. The author provides detailed descriptions of this information, along with RMON filters and alarms, which can be used to troubleshoot a network. New and improved standards RMONv2, SNMPv2, and SNMPv3 comprise the remainder of this book. RMONv2 allows network administration of more kinds of networks and devices. SNMPv2 provides enhanced administration capabilities, while SNMPv3 adds the security and encryption that was lacking in earlier versions of the protocol. This textbook is crammed with tables and statistics, and shows off the author's command of the relevant networking standards. Much more readable than the Request for Comments (RFC) documents that describe these standards, this title provides a comprehensive reference work on SNMP and RMON for the working Internet professional. --Richard Dragan The relentless growth in the information processing needs of organizations has been accompanied by rapid development in computer and data networking technology to support those needs, and an explosion in the variety of equipment and networks offered by vendors. Gone are the days when an organization would rely on a single vendor and a relatively straightforward architecture to support its needs. The world is no longer divided into the pure mainframe-based, IBM-compatible centralized environment and the PC-based, single-LAN-type, distributed environment. Today's typical organization has a large and growing but amorphous architecture, with a variety of local area networks (LANs) and wide area networks (WANs), supported by bridges and routers, and a variety of distributed computing services and devices, including PCs, workstations, and servers. And, of course, despite over two decades of premature eulogies, the mainframe lives on in countless distributed and a few centralized configurations. To manage these systems and networks, which continue to grow in scale and diversity, a rich set of automated network management tools and applications is needed. Fundamental to the operation of such tools and applications in a multivendor environment are standardized techniques for representing and exchanging information relating to network management. In response to these needs, managers and users have turned overwhelmingly to one standard: SNMP and the related RMON specification. SNMP (Simple Network Management Protocol) was initially specified in the late 1980s and quickly became the standard means for multivendor network management. However, SNMP was too limited to meet all critical network management needs. Three enhancements have solidified the role of SNMP as the indispensable network management tool. First the RMON (Remote Network Monitoring) specification, which is built on SNMP, was released in 1991. RMON was revised in 1995, and an enhancement to RMON, known as RMON2, was issued in 1997. RMON defines algorithms and databases for managing remote LANs. Second, an enhanced version of SNMP, known as SNMPv2, was released in 1993 and revised in 1995. SNMPv2 provides more functionality and greater efficiency than in the original version of SNMP. Finally, SNMPv3 was issued in 1998. SNMPv3 defines an overall framework for present and future versions of SNMP and adds security features to SNMP. This book covers the latest versions of SNMPv1, SNMPv2, and RMON 1 and 2, as well as the new SNMPv3. All these versions are in active use. Objective To manage today's systems effectively and to plan intelligently for the future use of network management systems, the systems manager needs an understanding
