Generated traffic under Errors TX using Pktgen 24.05.4 #260

Closed maxvanliefde closed 6 months ago

maxvanliefde commented 6 months ago

Hi, I updated Pktgen to the latest available version (Pktgen 24.05.4). I'm able to compile it using the lastest version of DPDK (24.07.0-rc0) on Ubuntu 22.04. However, when running Pktgen, all generated traffic is reported under Errors Tx. Packets are not received on the other server.

Here is the output I get:

$ sudo LD_LIBRARY_PATH=$LD_LIBRARY_PATH ./usr/local/bin/pktgen -n 4 -a 0000:01:00.1 --file-prefix max -l 0-8 -- -m [1/2/3:5/6/7].0 -P -v

Pktgen:/> str

Card is binded using DPDK-compatible driver:

$ ./dpdk/usertools/dpdk-devbind.py --status

============================================
0000:01:00.0 'Ethernet Controller E810-C for QSFP 1592' drv=uio_pci_generic unused=ice,vfio-pci
0000:01:00.1 'Ethernet Controller E810-C for QSFP 1592' drv=uio_pci_generic unused=ice,vfio-pci

I also notice that when using the latest version, only cores 1 and 5 are used, while when using version 23.03.0, cores 1,2,3,5,6,7 are used as expected.

Do you have any idea where the problem might be coming from?

Thanks in advance for your time. Regards, Max

The errors are from the NIC because the NIC detects suspicious frames. Try changing the destination MAC address to some other address. I believe the NIC is counting them as errors because the packets are invalid. The NIC has hardware to verify something is not spoofing packet and other suspected type packets. Sent from my iPhoneOn May 26, 2024, at 11:02 AM, Maxime Vanliefde @.> wrote: Hi, I updated Pktgen to the latest available version (Pktgen 24.05.4).

The errors are from the NIC because the NIC detects suspicious frames. Try changing the destination MAC address to some other address. I believe the NIC is counting them as errors because the packets are invalid. The NIC has hardware to verify something is not spoofing packet and other suspected type packets. Try using -m [2-4:5-7].0You gave cores 0-8 to dpdk but believed you may only have 8 cores if that correct the use -l 1-7 this give pktgen core 1 for display and timers which leaves 2-7 for the port. Sent from my iPhoneOn May 26, 2024, at 11:02 AM, Maxime Vanliefde @.> wrote: Hi, I updated Pktgen to the latest available version (Pktgen 24.05.4).
