### Zynq Ethernet Port Test Code Example

For testing the Ethernet ports on a Zynq device, one approach involves utilizing `iperf` for performance measurement under different conditions as described previously[^1]. Below is an illustrative Python script that automates setting up and running such tests between two machines over their respective Ethernet interfaces.

#### Prerequisites
Ensure both client and server have `iperf` installed. The following commands assume Linux environments where `iperf` can be easily set up via package managers like apt-get or yum depending upon distribution specifics.

#### Server Side Setup Script (`server_setup.sh`)

#!/bin/bash
# Start iperf server listening on default TCP port 5001.
iperf -s &
echo "Server started."

#### Client Side Testing Script (`client_test.py`)

import subprocess
import time

def run_iperf(server_ip):
    try:
        print("Starting dual-mode throughput test...")
        result = subprocess.run(['./iperf', '-c', server_ip, '-d'], capture_output=True, text=True)
        print(result.stdout)

        print("\nPerforming ping flood test...")
        result_flood = subprocess.run(['ping', '-f', server_ip], capture_output=True, text=True)
        print(result_flood.stdout.replace('.', 'Sent ').replace('\x08', 'Received '))
        
    except Exception as e:
        print(f"An error occurred during testing: {e}")

if __name__ == "__main__":
    SERVER_IP = "<Your_Server_IP>"
    run_iperf(SERVER_IP)

This setup allows users to evaluate network performance characteristics including bandwidth utilization and latency by leveraging built-in tools available within most Unix-like operating systems.
