The appliance installs standard DHCP fingerprints when you first install or upgrade to NIOS 8.6.x or laterlatest NIOS version. You cannot modify standard DHCP fingerprints nor delete them, but you can disable them. When you disable a DHCP fingerprint, the appliance disables the associated option number sequence and vendor ID, and it cannot match a remote device against the disabled DHCP fingerprint.
When you add a new DHCP fingerprint, the appliance marks it as a custom DHCP fingerprint. For information about adding custom DHCP fingerprints, see Adding New DHCP Fingerprints below. You can modify information about custom DHCP fingerprints, and you can delete them. For information, see Modifying Custom DHCP Fingerprints and Deleting Custom DHCP Fingerprints below. When you delete a custom DHCP fingerprint, the appliance moves it to the Recycle Bin, if enabled. You can later restore it from the Recycle Bin if needed.
Activities such as additions, modifications, and deletions of DHCP fingerprints are recorded in the audit log. For information about how to use the audit log, see Monitoring Tools.
