What happened: test failing My cluster is based on 1.16.3 release with multus CNI, when I ran networkingperf suite from , it is failing out with below error.

How to reproduce it (as minimally and precisely as possible): ./hack/ginkgo- -- -- Anything else we need to know?: This issue is there in current master branch also Both IPv4 and IPv6 Fails. The issue is container configuration in the test, the ENTRYPOINT for the agnhost image is agnhost , which will not take the argument as ""/bin/sh", "-c", "/usr/local/bin/iperf " + familyStr + "-c service-for-" + appName + " -p 8002 --reportstyle C && sleep 5"," hence container is coming out early, thus CNI is complaining. container configuration should take command as "/bin/sh" and argument as "-c", "/usr/local/bin/iperf " + familyStr + "-c service-for-" + appName + " -p 8002 --reportstyle C && sleep 5" .
