I followed your comment about the full PCI id and now the PDUMP application is working fine :). It creates the pcap file. My problem now is that I noticed that in the testpmd app I don't receive any packets. I write below the commands that I use to execute both apps: # sudo ./x86_64-native-linuxapp-gcc/app/testpmd -c 0x06 -n 4 --proc-type primary --socket-mem 1000 --file-prefix pg1 -w 0000:01:00.0 -- -i --port-topology=chained # sudo ./x86_64-native-linuxapp-gcc/app/dpdk-pdump -c 0xf8 -n 4 --proc-type auto --socket-mem 1000 --file-prefix pg2 -w 0000:01:00.0 -- --pdump 'device_id=0000:01:00.0,queue=*,rx-dev=/tmp/file.pcap' Before I execute these commands, I ensure that all the hugepages are free (sudo rm -R /dev/hugepages/*) In this way I split up the hugepages (I have 2048 in total) between both processes, as Keith Wiles advised me. Also I don't overlap any core with the masks used (0x06 and 0xf8) My NIC (Intel 82599ES), which PCI id is 0000:01:00.0, it is connected to a 10G link that receives traffic from a mirrored port. I show you the internet device settings related to this NIC: Network devices using DPDK-compatible driver ============================================ 0000:01:00.0 '82599ES 10-Gigabit SFI/SFP+ Network Connection' drv=igb_uio unused=ixgbe When I run the testpmd app and check the port stats, I get the following output: #sudo ./x86_64-native-linuxapp-gcc/app/testpmd -c 0x06 -n 4 --proc-type=auto --socket-mem 1000 --file-prefix pg1 -w 0000:01:00.0 -- -i --port-topology=chained EAL: Detected 8 lcore(s) EAL: Auto-detected process type: PRIMARY EAL: Probing VFIO support...

Did I missed any step in the configuration of the testpmd app? Thanks! José.
