Spirent TestCenter: Why I do not see all the ports available in my card after changing the card profile to STC-EL47?

Environment/Versions
 
  • STC-EL47
  • Spirent Enhanced Layer 4-7

 
Answer

That is expected, and this is due to a resources limitation on each card, when STC-EL47 profile is selected the number of ports available is less than the total ports on the card. 
The Enhanced L4-7 traffic profile limits the number of endpoints suitable for testing application layer functionality, but not performance.

As an example:
  • When STC-EL47 profile is selected, the number of ports available on MX2-1G module is half of the total available ports:
    • MX2-1G-S8 to have 4 ports
    • MX2-1G-S12 to have 6 ports
    • MX2-1G-S16 To have 8 ports 
 
  • When STC-EL47 profile is selected, the number of ports available on FX2-40G-Q5 is only 2 ports.

Starting on 5.11 there is a new profile called STC-EL47 Functional (that is not available on all the cards), so when available this has been designed to get full functionality on the card to run EL47 on all the ports.
