3.7 Configurations screen
The Configurations screen enables access to the configurable components in the controller.
3.7.1 About the configurable components
The configuration components are used to manage the controller and application features. The
base set of controller components support the applications that are embedded in the controller.
Adding or removing an SDN application might add or remove additional configuration component.
However, direct addition or removal of configuration components is not supported.
Each configuration component contains one or more component keys, each of which identify a
configurable property of the component.
CAUTION: Inappropriate changes to key values can result in severely degraded system
performance. For this reason, HP strongly recommends that managing the default key values be
done only by experienced network administrators and programmers who have a strong
understanding of SDN controller systems.
