There may be multiple errors in each device discovery and some might even need to be ignored. For example, if a device has multiple ports open, it tries all classifications till it finds the correct one. This error can be ignored, and to reduce the noise the administrator can use discovery behaviors. Authentication errors would derive from missing or invalid credential. Proper credentials with appropriate privileges should be added to the discovery credentials table.
