NMP engine- related objects like: snmpEngineID snmpEngineTime snmpEngineBoots snmpEngineMaxMessageSize snmpMPDMIB: This has the MIB module for message processing and dispatching. The subtrees under it in addition to snmpMDPConfor- mance are: snmpMPDAdmin: This module is used for the registration of message processing and dispatcher objects. snmpMPDMIBObjects: This provides a collection of objects for collect- ing information like number of packets dropped. snmpProxyMIB: This module has objects used to remotely configure the parameters in a proxy forwarding application. The proxy objects in snmp- ProxyMIB are defined under snmpProxyObjects. snmpTargetMIB This module has objects that are used for defining the addresses, destinations, and transport domains of the targets. In addition to snmpTargetConformance, there is snmpTargetObjects. The snmpTargetOb- jects in snmpTargetMIB module has tables that capture information about the transport domains and security information for sending messages to spe- cific transport domains. snmpNotificationMIB: This module has objects for configuring parameters to generate notifications. The snmpNotifyObjects under this module is used to set the notification types and targets that should receive notifications. It also has snmpNotifyConformance. snmpUsmMIB: This module has objects used in the user-based security. The usmMIBObjects perform authentication and ensure privacy is provided for management operations of users. This is along with usmMIBConformance for the conformance statements. Fundamentals of EMS, NMS and OSS/BSS snmpVacmMIB: This module has objects for view-based access control. The vacmMIBObjects can provide details of the access. This module also has vacmMIBConformance. The RFCs under which these modules are described are: RFC 2271 for snmp FrameWorkMIB RFC 2272 for snmpMDPMIB RFC 2273 for snmpProxyMIB, snmpTargetMIB, and snmpNotificationMIB RFC 2274 for snmpUsmMIB RFC 2275 for snmpVacmMIB 16.7 Conclusion This chapter is dedicated to the discussion of management informat
