Network Objects, Attributes, Exceptions, Faults, and Events
The sections that follow describe key attributes, diagnosed problems,
generated exceptions, detected events, and faults for the following categories of network object types in the
IP Availability Manager
and IP Performance Manager
data model:- SystemsRepresent computer-based entities. Examples of systems are Switch, Router, Hub, Bridge, and Host.
- Physical packagesRepresent physical objects that contain or host other components. Physical packages include Card, Chassis, and Rack.
- Network adaptersA network adapter represents a Layer 2 connection point. Network adapters include Port and Interface.
- Device connectionsA device connection represents the path between a pair of network adapters. Device connections include Cable, TrunkCable, and NetworkConnection.
- Service access pointsA service access point describes a logical endpoint that can be used to gain access to some network service. Examples of protocol endpoints are IP, IPv6, HSRPEndpoint, VRRPEndpoint, EVCEndPoints and MAC.Service access points are often described as protocol endpoints.
- Logical linksA logical link models the path that connects service access points to each other. Examples of logical links are IPNetwork, IPv6Network, and VLAN.
- CollectionsA collection represents a group of managed objects. Collections include Partition.
- Management agentsA management agent is a logical object that contains the information necessary to represent, configure, or manage some functionality provided by a system or software feature. Management agents include SNMPAgent and VRAgent.
- Redundancy groupsA redundancy group is a logical object that contains two or more objects that participate in a redundant configuration. Examples of redundancy groups are CardRedundancyGroup, HSRPGroup, VRRPGroup, and SystemRedundancyGroup.
- Logical devicesA logical device is an emulation of a hardware entity that might or might not be realized in physical hardware. Logical devices include:
- Processor
- Memory
- Disk
- FileSystem
- PowerSupply
- VoltageSensor
- TemperatureSensor
- FanIP Performance Manageralso instantiates device connection, collection, management agent, and redundancy group object types, but becauseIP Performance Managerdoes no analysis for these object types, they are not discussed here. Appendix A, "ECIM Instrumentation Class," in the describes all of the object types instantiated byIP Performance Manager.The describes all of the object types that are instantiated byIP Availability Manager.All of the object types instantiated byIP Availability ManagerandIP Performance Managerare available to aGlobal Consoleattached toIP Availability ManagerandIP Performance Manager, and a subset are available to aGlobal Consoleattached to theGlobal Manager. “Network topology” on page 32 provides a list of the object types imported by theGlobal Manager.
