Spirent TestCenter: The FX2 cards support 64K Tx streams per 40G QSFP+ port according the datasheet. If the customer use it in 10G mode do we have to divide this number by 4?

Environment/Versions
  • Spirent TestCenter
    • FX2
    • 40G versus 10G
    • Maximum number of streams the same when switching from 40G to 10G using the FX2-40G-Qx module
Answer
  • No difference when using it in 10G mode; i.e., it will still be 64k Tx streams per port.
  • No difference between the dual speed and 10G only module as well. 
  • The only number (as of today) that has to be divided by 4 is the capture buffer - it is 256 MB per port in 10G mode and 1G per port in 40G mode.
