Raw TCP over IPv4 traffic with fixed source and destination ports

[ankiroy8]

Config

• Two back-to-back connected test ports
  • One for tx
  • Another for rx
• One Flow with,
  • Fixed frame size of 128B
  • Rate of 50 PPS
  • Packet count 100
  • Packet headers ethernet, ipv4 and tcp
• TCP header with,
  • Fixed source port
  • Fixed destination port

Validation

• Push configuration
• Start capture on rx port
• Start transmit on tx port
• Wait until following is as expected,
  • Frames tx/rx, bytes tx/rx and transmit state in flow metrics
• Fetch capture and ensure following is as expected,
  • ethernet.ether_type
  • ipv4.protocol, ipv4.total_length
  • tcp.src_port, tcp.dst_port
  • size of each frame
  • (best effort) checksum of all headers
