Spirent TestCenter
It is a performance factor for GUI, we just limit what users can see in real time since there are too many variables and would require extra logic to determine what to display for each port When any port’s Analyzer Filters are changed from the default (32-bit Filter over Stream ID), then RX statistics will not be displayed in the real time Detailed Stream Results. TX statistics are displayed in the Detailed Stream Results and RX statistics in the Filtered Stream Results. The end of test result DB will have both the TX and RX statistics in the same Detailed Stream Results.
