After creating a CA Spectrum Global Collection (GC) configured with Policy Manager for setting attributes, the model attributes do not reset back to their default values after the model is removed from that GC.
For example: You have configured a Policy to monitor interfaces in a global collection and alarm on those interfaces when they go down. One of the criteria of the GC changes on the interface, and the interface is removed from the GC. The interface will still be monitored as the attributes to monitor the interface are still set. The model may have been removed from the GC, but Spectrum does not reset the attributes back to their default settings.
