[dpdk-users] Capture traffic with DPDK-dump
Hi, I made a test using the linux kernel to capture packets with the testpmd app. In this way I used the following command: # sudo ./x86_64-native-linuxapp-gcc/app/testpmd -c '0xfc' -n 4 --vdev 'eth_pcap0,rx_iface=eth0,tx_pcap=/tmp/file.pcap' -- --port-topology=chained I show below the output in this case: EAL: Detected 8 lcore(s) EAL: Probing VFIO support... EAL: VFIO support initialized PMD: Initializing pmd_pcap for eth_pcap0 PMD: Creating pcap-backed ethdev on numa socket 0 PMD: bnxt_rte_pmd_init() called for (null) EAL: PCI device :01:00.0 on NUMA socket -1 EAL: probe driver: 8086:10fb rte_ixgbe_pmd USER1: create a new mbuf pool : n=187456, size=2176, socket=0 Configuring Port 0 (socket 0) Port 0: XX:XX:XX:XX:XX:XX Checking link statuses...

[dpdk-users] Capture traffic with DPDK-dump
Hi,
Thank you very much for your response. 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 :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 :01:00.0 --
--pdump 'device_id=: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 :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
: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 :01:00.0 --

It doesn't receive any packet. Did I missed any step in the
configuration of the testpmd app?
Thanks!

[dpdk-users] Capture traffic with DPDK-dump
Hello everybody! 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 :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... EAL: VFIO support initialized EAL: WARNING: Address Space Layout Randomization (ASLR) is enabled in the kernel.
