The value of this object specifies the port-list used as match criterion for the source 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 tCpmIPv6FilterEntrySrcPort, tCpmIPv6FilterEntrySrcPortMask, tCpmIPv6FilterEntrySrcPortHigh and tCpmIPv6FilterEntrySrcPortOper are used as source port match criterion. When this object is set to a non-empty value then the objects tCpmIPv6FilterEntrySrcPort, tCpmIPv6FilterEntrySrcPortMask, tCpmIPv6FilterEntrySrcPortHigh and tCpmIPv6FilterEntrySrcPortOper are reset to their default values by the system. Vice versa, when a new (non-default) value is provided for one of the objects tCpmIPv6FilterEntrySrcPort, tCpmIPv6FilterEntrySrcPortMask, tCpmIPv6FilterEntrySrcPortHigh, or tCpmIPv6FilterEntrySrcPortOper then tCpmIPv6FilterEntrySrcPortList is reset to its default (empty) value by the system. Setting any one of the objects tCpmIPv6FilterEntrySrcPort, tCpmIPv6FilterEntrySrcPortMask, tCpmIPv6FilterEntrySrcPortHigh, tCpmIPv6FilterEntrySrcPortOper to a non-default value in combination with a non-default value for the object tCpmIPv6FilterEntrySrcPortList is rejected by the system
