This object specifies how destination port values are used when filtering ingress IPv6 traffic on a SAP (Service Access Point). It controls whether port comparisons use a single value, a range, or other matching operators to identify packets meeting specific criteria. Operators like 'none', 'eq' (equals), 'neq' (not equals), 'lt' (less than), and 'gt' (greater than) allow network operators to precisely match traffic by destination port for quality-of-service enforcement.
