Spirent TestCenter: Why only one of my streams is showing RX counters when both are showing TX correctly?
Environment/Versions
Simple configuration, 3 Spirent TestCenter ports connected to different DUT, one device per port, when building two streams (port1device -> port2device, and port1device -> port2device3) and have them go at the same time, one streamblock works, the other doesn't. Spirent counters show the correct amount of TX traffic on both stream, but one of the streams has RX, the other does not.
Answer
You need to make sure each device has a unique MAC ADDRESS, a configuration issue (Like having 2 devices with same MAC ADDRESS) makes the DUT to get confuse and send all the traffic to the same device.
Making each device has a unique MAC address solves this issue.
