GTP 10G traffic with trex

[Irem Yetikcan]

Hello,

I tried to create unidirectional 10Gbps traffic from 187 machine to 223 machine. I can only attach to 2.5G max.

Here are the commands and configurations I'm using. 

Network devices using DPDK-compatible driver
============================================
0000:af:00.0 '82599ES 10-Gigabit SFI/SFP+ Network Connection' drv=igb_uio unused=ixgbe,vfio-pci,uio_pci_generic

/etc/trex_cfg.yaml

- port_limit      : 2
  version         : 2
#List of interfaces. Change to suit your setup. Use ./dpdk_setup_ports.py -s to see available options
  interfaces    : ["af:00.0","dummy"]
  port_info       :  # Port IPs. Change to suit your needs. In case of loopback, you can leave as is.
      - default_gw      : 192.168.10.254
        dest_mac        : [0xb4,0x96,0x91,0xa6,0x33,0x11]
        ip : 192.168.10.187
  platform :
      master_thread_id: 0
      latency_thread_id: 8
      dual_if:
        - socket: 0
          threads: [24,25,26,27,28,29,30,31]

 Commands : 

./t-rex-64 -i --astf --software --tso-disable -c 8

./trex-console 

tunnel --type gtpu
tunnels_topo load -f astf/gtpu_topo.py // I just change ip from gtpu_topo.py according to my ip configuration .
start -f astf/udp1.py -m 1000000 

Version : v3.03  
 DPDK version : DPDK 22.03.0 

Tx port I used suppoted 10G traffic.

I need your help to understand the reason behind this limitation and how I can increase the traffic speed. Your suggestions and assistance would be highly appreciated. 

Thank you in advence.

Best Regards,

İrem Yetikcan.

Hi Irem, 

You can use STL mode for higher bandwidth. 

UDP1 profile is just an extreme simplified example. I would try http_simple.py profile 

Thanks
