Exactly as described, this is the administrative enable/disable state of this test instance, where enabling allocates hardware resources and, specifically for a reflector test instance, begins reflecting any matching test traffic received on the specified svid:cvid combination on the specified sub-port. For reflector instances this is the actual go-live switch, since nothing reflects until this is enabled, while for generator instances enabling this only reserves resources, a separate step from actually starting transmission, which happens via the distinct Started flag described elsewhere in this table. For example, enabling a reflector test instance's admin state with no corresponding generator instance yet enabled at the far end would successfully allocate resources and start listening, but nothing would actually be reflected until a generator begins sending matching tagged traffic.
