Manual Configuration

Ethernet Manual Configuration Test Application

Overview

This application demonstrates how to manually configure Ethernet speed and duplex settings instead of using the default autonegotiation mode. The program provides an interactive command-line interface for testing different Ethernet configurations and includes network diagnostic tools.

Features

Ethernet Configuration Options

• Autonegotiation mode - Automatically negotiates optimal speed and duplex
• 100Mbps Full Duplex - High-speed bidirectional communication
• 100Mbps Half Duplex - High-speed unidirectional communication
• 10Mbps Full Duplex - Standard speed bidirectional communication
• 10Mbps Half Duplex - Standard speed unidirectional communication

Network Diagnostic Tools

• ARP Cache Display - Shows the Address Resolution Protocol cache
• Network Counters - Displays various network statistics
• Ethernet Register Dump - Shows low-level Ethernet hardware registers
• Ping Functionality - Tests network connectivity to specified IP addresses
• Link Status Monitor - Displays current Ethernet link state and configuration
• System Timer - Shows OS tick counter and uptime

Usage

Interactive Menu Commands

After starting the application, use these single-character commands:

1 - Set Autonegotiate mode
2 - Set 100Mbps Full Duplex
3 - Set 100Mbps Half Duplex
4 - Set 10Mbps Full Duplex
5 - Set 10Mbps Half Duplex
A - Show ARP Cache
C - Show Counters
E - Show Ethernet Registers
P - Ping (Example: "P 192.168.1.1")
W - Show OS Seconds Counter
? - Display Menu

Ping Command Examples

• P - Ping the default gateway
• P 192.168.1.1 - Ping a specific IP address
• P 10.0.0.1 - Ping another specific address

Network Information Display

IPv4 Details

• IP address and subnet mask
• Primary and secondary DNS servers
• Default gateway
• Auto-IP configuration status

IPv6 Details

• Link-local addresses
• Router-assigned prefixes
• DHCP v6 leases with timing information
• Static address assignments
• DNS server information

Interface Status

• Link state (UP/DOWN)
• Current speed (10/100 Mbps)
• Duplex mode (Full/Half)
• MAC address information

Web Interface

The application includes a web server component that displays network configuration through a browser interface. The web page shows:

• Complete interface information
• Clickable links for IPv4 and IPv6 addresses
• DHCP lease timing details
• DNS server assignments

System Requirements

• NetBurner RTOS environment
• Ethernet hardware interface

Notes

• The application waits up to 5 seconds for network initialization on startup
• System diagnostics are enabled by default (should be disabled for production)
• All network interfaces are automatically detected and configured
• Link status is continuously monitored and displayed
