Target classes

A target class acts like a filter, allowing only those elements that are instances of the target class, or one of its subclasses, to become members of the group. Managed elements must pass the target class filter before they are compared against the matching criteria.

When you create a child group, the child group should have the same target class as its parent. The exception to this rule is when the new target class is a subclass of the parent group’s target class. For example, the ICIM_ManagedSystemElement class is near the top of the ICIM hierarchy. All of the other target classes are a subclass of ICIM_ManagedSystemElement. If ICIM_ManagedSystemElement is the target class of a parent group, you can select a different target class for a child group.

Similarly, VLAN, NetworkConnection, and IPNetwork are subclasses of ICIM_LogicalLink. If ICIM_LogicalLink is the target class of the parent, you can choose one of these three classes as the target class for a child group.

Target classes for selective groups lists the target classes you can assign to a selective group when you create it. Classes are listed in the order that they appear in the ICIM class hierarchy. The description indicates when a class is a subclass of another target class.

Table 1. Target classes for selective groups

Target class	Description
ICIM_ManagedElement	Base class for the ICIM system element hierarchy. This is the broadest target class.
UnitaryComputerSystem	Represents a single computer system. This is the superclass for the Bridge, Host, Hub, Probe, MSFC, Router, RSFC, RSM, Switch, TerminalServer, and Node classes.
ApplicationService	Represents service provided by software. Examples include email, web server, and database applications.
LogicalLink	Represents a link between two endpoints. Examples include database transactions, IP networks, and cables.
VLAN	Virtual LAN typical in switched networks. VLAN is a subclass of LogicalLink.
NetworkConnection	A connection between two routers, typically a virtual circuit. NetworkConnection is a subclass of LogicalLink.
IPNetwork	Subnet of an IP network. IPNetwork is a subclass of LogicalLink.
ServiceSubscriber	Customer who receives services provided through a service offering.
ServiceOffering	A service provided to customers.
