Activating and Deactivating Fingerprints

You must activate a custom fingerprint before the system can use it to identify hosts. After the new fingerprint is activated, the system uses it to re-identify previously discovered hosts and discover new hosts.

If you want to stop using a fingerprint, you can deactivate it. Deactivating a fingerprint causes a fingerprint to no longer be used, but allows it to remain on the system. When you deactivate a fingerprint, the operating system is marked as unknown for hosts that use the fingerprint. If the hosts are detected again and match a different active fingerprint, they are then identified by that active fingerprint.

Deleting a fingerprint removes it from the system completely. After deactivating a fingerprint, you can delete it.
