Send PCAP from multiple network card using dpdk pktgen

[Yaniv_Shoham]

I like to spread one pcap frames(round robin or every x frames) from multiple network cards.

Is it possible with dpdk-pktgen?

I try:
./app/pktgen -l 0-4 -n 6 --file-prefix=pg --proc-type auto --log-level 7 -m 32768 --legacy-mem -- -P -m "1.0,2.1" -T -s [0,1]:/data/traces/GTP-U_04-Octh13m47s04m454701-rx1.pcap

But pktgen show pcap only for port 0:

I all so try :
# ./app/pktgen -l 0-2 -n 6 --file-prefix=pg --proc-type auto --log-level 7 --socket-mem 32768,128 --legacy-mem -- -P -m "2.[0-1]" -T -s [0-1]:/data/traces/MME-23-Seph13m55s26m265439-rx_1.pcap

And still, the pcap does not send over port 0&1.

Hello Yaniv,

Thank you for posting in Intel Ethernet Communities.

In order for us to provide the most accurate assistance on this scenario, we just wanted to confirm a few details about your system:

What is the model of the motherboard?

What is the OS, kernel version and system? Have you apply with the latest update of driver/firmware?

To check Linux Kernel version, try the following commands: uname -r

What is the model of NIC/s that you are testing with?

Is this a new computer? Was it working fine before? Did you make any recent hardware/software changes?

Best regards,

Hi,
I forgot to mention that tanks for this page (https://pktgen-dpdk.readthedocs.io/en/latest/usage_pktgen.html) I success to send over 2 port at the same time using two pktgen instances.
The question is how to spread( load balance ) one pcap over 2 ports using one pktgen instance.

Environment:

• motherboard: no idea how to get this info. its ProLiant DL360 Gen10 with Intel(R) Xeon(R) Gold 6138.  it pcie gen 3.
• OS: Centos 7.9
• Have you apply with the latest update of driver/firmware? from last year.
• # uname -r
  3.10.0-1160.76.1.el7.x86_64
• Intel(R) Eth E810-CQDA2 with 2 ports of 100Gbps (the speed limitation of motherboard::pcie 3.0 is not an issue. we need 30Gbps from every port).
  
• Is this a new computer? from 2017. Was it working fine before? Yes, and still work fine. Did you make any recent hardware/software changes? No.
