Did you whitelist the PCI devices in VPP configuration (https://fdio-vpp.readthedocs.io/en/latest/gettingstarted/users/configuring/startup.html#dpdk)? If you are using CentOS/RHEL, can you try disabling SELinux ('setenforce 0' under Linux) and see if it is better? Otherwise, does the Mellanox interfaces work with DPDK testpmd? If it still does not work, can you share the output of: - under Linux: lspci, lsmod, dmesg - under VPP: show pci, show logging > Query 2:- [...] > Can anyone comment whether it is the correct way of testing Mellanox NIC > with vpp 19.04? I do not have a definitive answer on this: the native RDMA driver is still experimental but should work (and I can help if it is not the case), and it will probably become the preferred way in the future. If it works for you with acceptable performance, go for it :) Best ben
