Chapter 1, "What Is SNMP?" provides a nontechnical overview of
network management with SNMP. We introduce the different versions of
SNMP as well as the concepts of managers and agents.
Chapter 2, "A Closer Look at SNMP" discusses the technical details of
SNMP. We look at the Structure of Management Information (SMI) and
the Management Information Base (MIB) and discuss how SNMP actually
works; i.e., how management information is sent and received over the
network.
Chapter 3, "NMS Architectures" helps you to think about strategies for
deploying SNMP.
Chapter 4, "SNMP-Compatible Hardware" discusses what it means when a vendor
says that its equipment is "SNMP-compatible."
Chapter 5, "Network-Management Software" introduces some of the available
network-management software. We discuss the pros and cons of each
package and provide pointers to vendors' web sites. We include
both commercial and open source packages in the discussion.
Chapter 6, "Configuring Your NMS" provides a basic understanding
of what to expect when installing NMS software by looking at two NMS
packages, HP's OpenView and Castle Rock's SNMPc.
Chapter 7, "Configuring SNMP Agents" describes how to configure the
Windows SNMP agent and several SNMP agents for Unix, including the
Net-SNMP agent. To round the chapter out, we discuss how to configure
the embedded agents on two network devices: the Cisco SNMP agent and
the APC Symetra SNMP agent.
Chapter 8, "Polling and Setting" shows how you can use
command-line tools and Perl to gather (poll) SNMP information and
change (set) the state of a managed device.
Chapter 9, "Polling and Thresholds" discusses how to configure OpenView and
SNMPc to gather SNMP information via polling. This chapter also
discusses RMON configuration on a Cisco router.
Chapter 10, "Traps" examines how to send and
receive traps using command-line tools, Perl, OpenView, and other
management applications.
Chapter 11, "Extensible SNMP Agents" shows how several popular SNMP
agents can be extended. Extensible agents provide end users with a
means to extend the operation of an agent without having access to
the agent's source code.
Chapter 12, "Adapting SNMP to Fit Your Environment" is geared toward Perl-savvy
system administrators. We provide Perl scripts that demonstrate how
to perform some common system-administration tasks with SNMP.
Chapter 13, "MRTG" introduces one of the most widely used
open source SNMP applications, the Multi Router Traffic Grapher
(MRTG). MRTG provides network administrators with web-based usage
graphs of router interfaces and can be configured to graph many other
kinds of data.
Appendix A, "Using Input and Output Octets" discusses how to use OpenView
to graph input and output octets.
Appendix B, "More on OpenView's NNM" discusses how to graph external
data with Network Node Manager (NNM), add menu items to NNM,
configure user profiles, and use NNM as a centralized communication
interface.
Appendix C, "Net-SNMP Tools" summarizes the usage of the Net-SNMP
command-line tools.
Appendix D, "SNMP RFCs" provides an authoritative list of the
various RFC numbers that pertain to SNMP.
Appendix E, "SNMP Support for Perl" is a good summary of the SNMP Perl
module used throughout the book.
Appendix F, "SNMPv3" provides a brief introduction to
SNMPv3. Two configuration examples are provided: configuring SNMPv3
on a Cisco router and configuring SNMPv3 for Net-SNMP.
