why imix.py doesn't work?
hem...@mnkcg.com
My company could get trex up and running in two days with a DUT as VPP for IPv4. In another two days, we could make trex work for IPv6. I do get worried when scripts included with trex don’t work or we don’t know what we are doing wrong.
I have used scripts/stl/imix.py and see its failure with trex-console below.
trex>start -f stl/imix.py -m 20pps
start - Port 0 dest MAC is invalid and there are streams without explicit dest MAC.
I edited imix.py Ether() to include src, dst, and type and then the above error was fixed. Then I started traffic but Rx packets are getting dropped in large quantity. Debugging VPP, I see VPP is trying ARP and doesn’t receive a reply and drops the packet.
I used this CLI to run trex: sudo ./t-rex-64 -i -c 1
How is one supposed to run imix.py and have testing pass?
Thanks,

I am all set.
I went back to v2.86 trex and now have DNS example working with DUT as a VPP node and using 2-node topology.
sudo ./t-rex-64 -f cap2/dns.yaml -d 1 -l 1000
