The value of this object specifies the port-list used as match criterion for the destination port. The value specified for this object must correspond to a port-list defined in TIMETRA-FILTER-MIB::tFilterPortListTable. If the value of this object is empty then the values of the objects tCpmIPv6FilterEntryDestPort, tCpmIPv6FilterEntryDestPortMask, tCpmIPv6FilterEntryDestPortHigh and tCpmIPv6FilterEntryDestPortOper are used as destination port match criterion. When this object is set to a non-empty value then the objects tCpmIPv6FilterEntryDestPort, tCpmIPv6FilterEntryDestPortMask, tCpmIPv6FilterEntryDestPortHigh and tCpmIPv6FilterEntryDestPortOper are reset to their default values by the system. Vice versa, when a new (non-default) value is provided for one of the objects tCpmIPv6FilterEntryDestPort, tCpmIPv6FilterEntryDestPortMask, tCpmIPv6FilterEntryDestPortHigh or tCpmIPv6FilterEntryDestPortOper then tCpmIPv6FilterEntryDstPortList is reset to its default (empty) value by the system. Setting any one of the objects tCpmIPv6FilterEntryDestPort, tCpmIPv6FilterEntryDestPortMask, tCpmIPv6FilterEntryDestPortHigh, tCpmIPv6FilterEntryDestPortOper to a non-default value in combination with a non-default value for the object tCpmIPv6FilterEntryDstPortList is rejected by the system.
