[vpp-dev] VPP Iperf3 test

Shankar Raju Tue, 22 Mar 2022 13:39:42 -0700

Hi Guys,

I’m trying to test VPP configuration with iperf3 and I running into the 
following issue.
•         Iperf3 client is able to make a connection with the server, but the 
client receives data for the first 0-1 second and then it does not receive any 
traffic from the server. The bitrate is zero after that.


Here’s my startup.conf and vcl.conf

STARTUP.CONF

unix {
  nodaemon
  log /var/log/vpp/vpp.log
  full-coredump
  cli-listen /run/vpp/cli.sock
  gid vpp

  ## run vpp in the interactive mode
  # interactive

  ## do not use colors in terminal output
  # nocolor

  ## do not display banner
  # nobanner
}


api-segment {
  gid vpp
}

socksvr {
  default
}

dpdk {
  uio-driver vfio-pci
  dev 0000:00:06.0 {
    name eth1
  }
}

buffers {
  buffers-per-numa 65536
  default data-size 2048
}

cpu {
  main-core 0
  workers 1
}

session {
  evt_qs_memfd_seg
}

VCL.CONF
vcl {
  rx-fifo-size 800000
  tx-fifo-size 800000
  app-scope-local
  app-scope-global
  api-socket-name /var/run/vpp/api.sock
}

Steps I followed:

•         Set IP address through vpcctl
Iperf3 server command:
•         export LD_PRELOAD=$LDP_PATH && export VCL_CONFIG=$VCL_CFG
•         iperf3 -4 -s -A 1 -V

iperf3 client command:
•         export LD_PRELOAD=$LDP_PATH && export VCL_CONFIG=$VCL_CFG
•         iperf3 -c 10.21.120.181 -u -A 1 -V -b 0

Client side output:

Please let me know if I’m configuring something wrong.
