The Grouping Manager
Note that you can also remove resources by locatingthem using the Find function, and
removing them using the search results list. See “Searching for a Resource”on page 8-23
for more information on the Find function.
Removing a resource from all groups of which it is a member is the equivalent of
destroying the resource.
Adding Relationships to a Resource
Individual resources cannot have children. However, certain types of resources (Hosts,
Users, or Ports) can have relationships. Devices cannot have either relationships or
children.
For example, a Host may have a relationship with a User, which indicates that the User is
associatedwith the IP address of that Host. A Host may also have a relationship with a
port, indicating that the host communicates over that port.
These relationships may be used by the Policy Manager applet to create low-level QoS
policy rules based on named higher-level objects such as users and hosts. Relationships
can be created between the following:
• Hosts and Users
• Hosts and Ports
• Users and Ports
These relationships are always reciprocal: when you create a relationship between two
resources, it is added simultaneously to both resources.
1 In the Component Tree, select the resourceto which you wantto add a relationship, so
that it is displayed in the Resource Details view.
2 Click the tab labeled Relationships to display the list of children belonging to this
group.
3 Click the Add button at the bottom of the list of Children to display the Add
Relationship to Group pop-up dialog, as shown in Figure 8-4.
