The Simple Network Management Protocol (SNMP) is an Internet-standard protocol for managing hosts on an IP network. Devices that typically support SNMP include routers, switches, servers, workstations, printers, modem racks, UPSs, and more.Essential SNMP is a practical introduction to SNMP for network and system administrators. It starts with the basics of SNMP and how it works, along with the technical background to use it effectively. The book covers OIDs, MIBs, community strings, traps, and other technical elements. But the main focus is on practical network administration: how to configure SNMP agents and network management stations, how to use SNMP to retrieve and modify variables on network devices, how to configure management software to react to traps sent by managed devices.Essential SNMP explores both commercial and open source packages, including HP's OpenView, Castle Rock's SNMPc, the Net-SNMP tools, Simon Leinen's Perl SNMP support, and MRTG. Administrators will come away with ideas for writing scripts to help them manage their networks, create managed objects, and extend the operation of SNMP agents. In addition to SNMPv1 and v2, the book covers SNMPv3, which has just started to appear in commercial products as of this printing.
Because it's oriented toward SNMP as a tool, much of the coverage in this book has to do with software that uses SNMP to provide network monitoring and control services. After a strengths-and-weaknesses overview of a number of SNMP packages, the authors use mainly HP OpenView, Castle Rock SNMPc, and Net-SNMP (the last in combination with Perl scripting) to demonstrate how SNMP works and how to take advantage of it. It's the scripting that really distinguishes this book from other SNMP books, by the way. It's integral to the authors' presentation, and the latter half of this book is packed with shell and Perl listings. --David Wall
Topics covered: Simple Network Management Protocol (SNMP) and its applicability as a network management tool. Details like object identifiers (OIDs), management information bases (MIBs), traps, and community strings are defined and explained. The configuration of SNMP agents is detailed for several software packages and operating systems, and the integration of SNMP and scripts (in shell languages and in Perl) is covered nicely.
