چکیده

The SNMP development tool provides an environment for rapid agent prototyping and construction. With the following information provided, this tool is used to set up a running multilingual SNMP agent: a description of a Management Information Base (MIB) in Abstract Syntax Notation One (ASN.1) instrumentation functions for the managed objects in the MIB, written in Erlang. The advantage of using an extensible agent toolkit is to remove details such as type-checking, access rights, Protocol Data Unit (PDU), encoding, decoding, and trap distribution from the programmer, who only has to write the instrumentation functions which implement the MIBs. The tedious get-next function only has to be implemented for tables, and not for every variable in the global naming tree. This manual describes the SNMP development tool, version 3.0, as a component of the Erlang/Open Telecom Platform development environment. It is assumed that the reader is familiar with the Erlang Development Environment which is described in a separate User's Guide. The tool requires Erlang release 4.7 or later. In addition to this introductory chapter, this User's Guide contains the following chapters: Chapter 2: " Functional Description " describes the features and operation of the SNMP development toolkit. It includes topics on Subagents and MIB loading, Internal MIBs, and Traps. Chapter 3: " Instrumentation Functions " describes how instrumentation functions should be defined in Erlang for the different operations. Chapter 4: " MIB Compiler " describes the features and the operation of the MIB compiler. Chapter 5: " Running the Agent " describes how to start and configure the agent. Topics on how to debug the agent are also included. Chapter 6: " Implementation Example " describes how an MIB can be implemented with the SNMP Development Toolkit. Implementation examples are included. Chapter 7: " Advanced Topics " describes subagents, agent semantics, audit trail logging, and the consideration of distributed tables. Chapter 8: " Definition of Configuration Files " is a refence chapter which contains more detailed information about the configuration files. Chapter 9: " Definition of Instrumentation Functions " is a reference chapter which contains more detailed information about the instrumentation functions. Chapter 10: " Definition of Net if " is a reference chapter which describes the Net if function in more detail. Appendix A describes the conversion of SNMPv2 to SNMPv1 error messages. A multilingual SNMP manager that can be used for simple interactive testing, and for writing test suites. The …

White Paper Remote Management: SNMP Sub-agent for Intel® Server Hardware

Simple Network Management Protocol (SNMP) is used ubiquitously to monitor and control any device over the network by exchanging SNMP messages. The SNMP, defined by IETF [1], has gained significant popularity among the software, hardware, telecom, and network industries. SNMP was derived from its predecessor SGMP (Simple Gateway Management Protocol). This is considered as a de facto and standard...
