This defines the type of control to be instrumented on this port. include: When this object is set to include, port based VLI will process only the work groups defined in the corresponding work group table entries. All other work groups will be filtered out on this port. exclude: When this object is set to exclude, port based VLI will process all work groups except those listed in the corresponding work group table entries. Those listed in the lightStreamVliPortWorkGroupTable will be filtered. The default state of exclude with an empty work group table allows all work groups to be recognized as valid on this port.
