I am new in DPDK. I'm trying simply to capture traffic from a 10G physical NIC. I installed the DPDK from source files and activated the following modules in common-base file: CONFIG_RTE_LIBRTE_PMD_PCAP=y CONFIG_RTE_LIBRTE_PDUMP=y CONFIG_RTE_PORT_PCAP=y Then I built the distribution using the dpdk-setup.h script. Also I add hugepages and check they are configured successfully: AnonHugePages: 4096 kB HugePages_Total: 2048 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB To capture the traffic I guess I can use the dpdk-pdump application, but I don't know how to use it. First of all, does it work if I bind the interfaces using the uio_pci_generic drive? I guess that if I capture the traffic using the linux kernel driver (ixgbe) I will loose a lot of packets. To bind the NIC I write this command: sudo ./tools/dpdk-devbind.py --bind=uio_pci_generic eth0 When I check the interfaces I can see that the NIC was binded successfully. Also I checked that mi NIC is compatible with DPDK (Intel 8599) Network devices using DPDK-compatible driver ============================================ 0000:01:00.0 '82599ES 10-Gigabit SFI/SFP+ Network Connection' drv=uio_pci_generic unused=ixgbe,vfio-pci To capture packets, I read in the mailing list that it is necessary to run the testpmd application and then dpdk-pdump using different cores. So I used the following commands: sudo ./x86_64-native-linuxapp-gcc/app/testpmd -c 0x6 -n 4 -- -i sudo ./x86_64-native-linuxapp-gcc/app/dpdk-pdump -c 0xff -n 2 -- --pdump 'device_id=01:00.0,queue=*,rx-dev=/tmp/file.pcap' Did I miss any step? Is it necessary to execute any more commands when running the testpmd app in interactive mode? When I execute the pdump application I get the following error: EAL: Detected 8 lcore(s) EAL: Probing VFIO support...
