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