Hmm.
I ran a couple of tests and found that they do come back actually. How did you specify to only add “new things”?
The only way I could exclude them was to set the Advanced Filter to exclude certain keywords in the Interface Alias. Unfortunately this setting isn’t saved with the Discovery Job so it can’t be set as a scheduled discovery. Not sure if this is a “feature” or a “bug”.
I guess it is back to manual discoveries again.
