8-4 ExtremeWare EPICenter Software Installation and User Guide
The Grouping Manager
Some predefined resources, such as devices and imported resources, may also have
predefined attributes. For example, device resources have their IP address as an attribute.
Imported resources may bring with them sets of attributes determined by the content and
configuration of the import source. Certain attributes, such as IP/subnet address and
DLCS ID, are used by the optional Policy Manager applet to help it map between
high-level named resources such as Users, andthe informationrequired togeneratea QoS
policy (IP address and port information).
You can also define attributesof your own,and then use them assearch criteria when you
want to find sets of resources with common attributes.
Relationships between Resources
THe Grouping Manager also supports “relationships” between User, Host, and Port
resources. These relationships are used by the optional Policy Manager applet, and help
the Policy Manager generate specific QoS rules that it derives from high-level policy
specifications that are given in terms of named objects such as users or hosts. See the
ExtremeWare EPICenter Policy Manager Software User Guide for details.
