If different from 0, the object tSapIngressIPCritSrcIpFullMask specifies the IP Mask value for this policy IP Filter entry. The mask is ANDed with the received Source IP address to match the tSapIngressIPCriteriaSourceIpAddr. If the value of tSapIngressIPCriteriaSourceIpMask is non zero, it will be equal to the mask expressed in the object tSapIngressIPCritSrcIpFullMask. If both tSapIngressIPCriteriaSourceIpMask and tSapIngressIPCritSrcIpFullMask are set to 0, no matching is done on the Source IP address. If a regular mask is specified for tSapIngressIPCritSrcIpFullMask then the value of tSapIngressIPCriteriaSourceIpMask will be changed to reflect this value. The value of object tSapIngressIPCriteriaSourceIpAddr needs to be always set together along with tSapIngressIPCriteriaSourceIpMask or tSapIngressIPCritSrcIpFullMask, otherwise an 'inconsistentValue' error is returned.
