8-18000-A2-GB21-20 November 1997SNMP Agent8OverviewThe Simple Network Management Protocol (SNMP) is an application-levelprotocol used in network management. A Network Management System (NMS),such as Paradyne’s DCE Manager, communicates to an SNMP agent via SNMPin order to obtain (get) specific parameters or variables within control of theSNMP agent.When DCE Manager is configured properly, it can communicate with the HotWireDSLAM SNMP agent. Almost all communications between the DCE Manager andthe HotWire DSLAM SNMP agent originate with a request message from theDCE Manager to the HotWire DSLAM. When the DSLAM receives the request,the HotWire DSLAM SNMP agent processes the request message and transmitsa response (positive or negative) message back to the DCE Manager. Whencertain significant events occur within the SNMP agent, this can result intransmission of unprompted SNMP trap messages to the DCE Manager. (Notethat the HotWire DSLAM SNMP agent is SNMP Version 1 (V1) compliant withcommunity-based management.)This chapter describes what you need to know to configure the SNMP agentwithin the HotWire DSLAM. This chapter does not, however, describe theprocedures on how to configure the SNMP agent. For those procedures, see theHotWire DSLAM for 8540 and 8546 DSL Cards User’s Guide.MIB ComplianceVarious pieces of configuration, status, and statistical data within the HotWireDSLAM SNMP agent form a database of information that is accessible from theDCE Manager. This collection of information is called a Management InformationBase (MIB). The basic definitions of the content of an SNMP agent’s MIB aredefined within various Internet Request for Comments (RFC) documents.An HP OpenView MIB browser requires the operator to load the appropriate MIBfiles into its database before it can manage the HotWire DSLAM network. Formore information about DCE Manager, see theDCE Manager for HP OpenViewfor Windows User’s Guide or theDCE Manager User’s Guide.
