C-8 Router Option Module User Guide 61200350L1-1 Appendix D SNMP UNDERSTANDING SNMP The Simple Network Management Protocol (SNMP) is the de facto standard for managing commercial Transmission Control Protocol/ Internet Protocol (TCP/IP) networks. It allows vendor equipment to be managed from a single control console. The term SNMP broadly refers to the message protocols used to exchange information between the network and the managed devices, as well as to the structure of network management databases. SNMP Components: SNMP has three basic components: Network Manager, Agent, and MIB. Network Manager • A control program that collects, controls, and presents data pertinent to the operation of the network devices. • Resides on a network management station. Agent • A control program that responds to queries and commands from the network manager. • Returns requested information or invokes configuration changes initiated by the manager. • Resides in each network device connected. 61200350L1-1 Router Option Module User Guide Appendix D: SNMP MIB • An index to the organized data within a network device. • Defines the operating parameters that can be controlled or monitored. When requesting the network manager to retrieve or modify a particular piece of information about a network device, the network manager transmits the request to that network device. The agent in that device interprets the incoming request, performs the requested task, and sends its response to the network manager. The network manager collects all the data from the various network devices and presents it in a consistent form. Using SNMP Version 1, the network manager can issue three types of commands: GetRequest: This command retrieves a single item or the first in a series from a network device. GetNextRequest: This command retrieves the next item in a series from a network device. SetRequest: This command writes information to a network device. The network device issues two types o...
