The WLAN NICs do not allow reservation, when trying to reserve those ports GUI freezes and see port reservation error: "Failed to reserve the following ports...", please see screenshots attached. Ethernet ports reserve fine.

Versions tried: 5.11 , 5.13. Upgrade / Downgrade / Re-image, doesn't help.



Spirent TestCenter
  • v5.11
  • v5.13


Seems that the issue is with the Management IP address being in the 192.168.1.X range, which has issues with internal IP addressing. As per comments from engineering, the C50 (WLAN models) should not have the Management IP address in the 192.168.1.X range, else they will cause reservation freeze issues, as the BLL can’t communicate with internal IPs in the range.
