Summary
The objectives of this report are to provide the reader with a clearer understanding of network management, the concepts inherent in the Simple Network Management Protocol (SNMP), comparisons of SNMP with other network management protocols, how SNMPs are used in network management, and, finally, to provide the results of experiments carried out using several different modem configurations.

SNMP is an internet-standard system of digital message format, or protocol, for managing devices on Internet Protocol (IP) networks. Routers, switches, servers, workstations, printers, modems are examples of such devices that support SNMP. It was introduced in 1988 to meet the growing need for managing Internet Protocol (IP) devices [2] and is used mostly in network management systems to monitor network-attached devices for conditions that warrant administrative attention. SNMP includes an application layer protocol, a database schema, and a set of data objects [1].

Network management is a general concept that employs the use of various tools and techniques, and systems to aid human beings in managing various devices, system, or networks. One such model of network management is called FCAPS, or Fault Management, Configuration Management, Accounting Management, Performance Management, and Security Management. Under the SNMP system and the FCAPS model, one or more administrative computers, called managers, are tasked to monitor and/or manage one or more pieces of software, called agents, which run on the network device. Specifically, the manager is a server which is running some kind of software system that can handle management tasks for a network. SNMP uses the User Datagram Protocol (UDP) as the transport protocol for passing data between managers and agents. The upside to the unreliable nature of UDP is that it requires low overhead, so the impact on the network’s performance is reduced.

Management information is the operational parameters of SNMP-capable devices. The definition of managed objects can be broken down into three attributes: Name, Type and syntax, and Encoding. Managed objects are organized into a treelike hierarchy, this is the basis for SNMP’s naming scheme. Care must be taken when identifying managed objects or Object Identifiers (OIDs), across different versions of SNMP as there are enhancements to the naming scheme. Table of Contents
