The value of tSapEgrIPCritSrcIpPrefixList 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 tQosPrefixListTable. If the value of this object is empty then the values of the objects tSapEgrIPCritSourceIpAddr and tSapEgrIPCritSourceIpMask or tSapEgrIPCritSrcIpFullMask are used as source ip address match criterion. When this object is set to a non-empty value then the objects tSapEgrIPCritSourceIpAddr, tSapEgrIPCritSourceIpMask and tSapEgrIPCritSrcIpFullMask are reset to their default values by the system. Vice versa, when a new (non-default) value is provided for the objects tSapEgrIPCritSourceIpAddr and tSapEgrIPCritSourceIpMask or tSapEgrIPCritSrcIpFullMask then this object is reset to its default (empty) value by the system. An attempt to set tSapEgrIPCritSrcIpPrefixList to a non-default value in combination with setting any of tSapEgrIPCritSourceIpAddr and tSapEgrIPCritSourceIpMask or tSapEgrIPCritSrcIpFullMask to (a) non-default value(s) is rejected by the system. This object is only supported when the value of tSapEgrIPCritAddrType is 'ipv4 (1)'. An inconsistentValue error is returned when the value of tSapEgrIPCritSrcIpPrefixList is set to non-default value and the value of tSapEgrIPCritAddrType is not 'ipv4 (1)'.
