Spirent TestCenter: 5.23 AION Licensing: License Limits for your configuration may have been exceeded, Click here to learn more

Symptoms

When using AION licensing on 5.23 release, the STC GUI complains with a message saying "License Limits for your configuration may have been exceeded, Click here to learn more", the GUI is complaining about "Virtual Medium Scale Bandwidth" licenses, even though the Warning is in there, this seems to be just an esthetical issue because you can run your test and the traffic flows as expected, however this is not a good look because it is very confusing
 

 

If you click on "Click here to learn more", you the GUI will indicate you are missing some "Medium Licenses", even though those "Medium Licenses" are not listed, we do have "Virtual High Scale Bandwidth", and as per the GUI NOTE, being  "Enable AION Licensing" - Alternate License Checkout ENABLED, having the High Scale Bandwidth should suffice
 
  
 
 
 
Same exact configuration in 5.19 doesn't exhibits this behavior.

    • CR-01502747
    • Subject: 5.23 - STCv gets AION license error: "License Limits for your configuration may have been exceeded, Click here to learn more"
    • Date/Time Opened: 05/Jul/21 10:30 AM
    • Date/Time Closed: 07/Jul/21 9;41 AM
    • Target Release: 5.24 (Late July 2021 release)
 
Root Cause

This issue was caused due to a couple of things which were fixed in 5.24:
  1. In certain cases the licenses flagged as missing were not getting cleared even after an alternate valid license was found.
  2. On-the-fly license checking (OTF) was flagging an error even after the license was checked out by the same config.  This was observed in the in-house test workspaces where only one license was available and if that was checked out it showed up as being in use. In that case the app needed to confirm that the license was checked out and was being used by the same config performing the OTF check
