TestCenter: What is reason four (4) bytes are missing from the capture of the traffic created by Generate Stream Block (PCAP or capture replay) with Spirent TestCenter?



  •  When you Generate Stream Block from PCAP, it recognizes the FCS and does not include as part of the data
  • There is an option in TestCenter under Settings -> Traffic -> Generate Stream Block Setting -> to Uncheck -> Exclude Ethernet FCS (By unchecking this TestCenter will decode the Ethernet checksum as payload) and TestCenter will add FCS
