Hi, Daniel, The error that you get, "Failed to parse device "net_pcap_rx_0", hints that DPDK was built without PCAP support on your setup. What does "cat build/.config | grep CONFIG_RTE_LIBRTE_PMD_PCAP" show ? if it is "n", can you please set it to "y", then build DPDK and try again? Regards, Rami Rosen
