Spirent TestCenter: GUI loses connection to chassis after some time.

Environment/Versions
  • Below is some information from the logs.
  • When the issue occurs we have all sorts of connection issues. Here is just an example:

  • The TestCenter then looks at the Windows PC event logs.

    • Network link is disconnected.
  • We can see in the windows PC event logs that there was some ethernet connection issue and network link disconnected.
Answer
  • It was found that the PC had a sleep time and if no activity the network link is dropped.
  • It doesn’t say the PC went to sleep but if the network link goes down then the TestCenter GUI will lose connection and the GUI will give a message and close down.
  • After disabling sleep on the PC, the connection became stable.
