The value of tSapIngIPv6CritDstIpPrefixList specifies the IP prefix list used as match criterion for the destination ip address. The value specified for this object must correspond to a prefix list defined in tQosPrefixListTable. If the value of this object is empty then the values of the objects tSapIngressIPv6CriteriaDestIpAddr and tSapIngressIPv6CriteriaDestIpMask or tSapIngressIPv6CritDstIpFullMask are used as destination ip address match criterion. When this object is set to a non-empty value then the objects tSapIngressIPv6CriteriaDestIpAddr, tSapIngressIPv6CriteriaDestIpMask and tSapIngressIPv6CritDstIpFullMask are reset to their default values by the system. Vice versa, when a new (non-default) value is provided for the objects tSapIngressIPv6CriteriaDestIpAddr and tSapIngressIPv6CriteriaDestIpMask or tSapIngressIPv6CritDstIpFullMask then this object is reset to its default (empty) value by the system. An attempt to set tSapIngIPv6CritDstIpPrefixList to a non-default value in combination with setting any of tSapIngressIPv6CriteriaDestIpAddr and tSapIngressIPv6CriteriaDestIpMask or tSapIngressIPv6CritDstIpFullMask to (a) non-default value(s) is rejected by the system
