Hi,
in my view rediscovery is incredibly broken. When a device is rediscovered, the changes made after the first discovery are mostly reverted. For Example I added a switch today and modified the device type. Also I made a change to a switch port description. Upon rediscovery it was again added (as a second device with the same IP and DNS name) - wrong type, no port descriptions at all.
At least give us the option to skip existing devices during discovery. Also updating the Port descriptions of existing devices would be extremely helpful.
Please chime in if you agree to this suggestion
