Hi,
Even though I am able to see the udp packets on the server side why do I see such a high drop rate?
I'm able to transfer UDP packets from client to server using
<trex> start-f stl/udp_1pkt_simple.py -m 100mbpsThis is what the tui output looks like

Drop rate counter is not valid in case of one port configuration

Running this example on docker
I don't see any information regarding jitter and latency in the <tui> l - latency .
Is there any additional configuration needed to enable it?
This is what the latency stats look like

Adding in the flow_stats resulted in all latency and jitter to be 0.
flow_stats = STLFlowLatencyStats(pg_id = 7)

Hi, You are using it right. Latency works when Tx and Rx on the same TRex ..
In your case you don't get the latency traffic back so there is no way to calculate the latency

Hi Hanoh,
Would you suggest using STF/ASTF mode since Tx and Rx are not on the same TRex ?
