Ethernet shield Blink / Flash Link light on Connected Switch

Hi, Can anyone help me.

I have been searching for some time to figure out how to make the Arduino Wiznet W5100 chipset Ethernet shield flash / Blink the Link Light on the Switch.

I a trying to build a simple network test tool and this function would be handy in identifying the port the Arduino is connected to.

Any help would be so grateful in solving the problem.

John.

Hi sorry if my post did not make any sense.

I am trying to build a network tester using an arduino and an ethernet shield.

One of the functions is to allow you to find the network port the arduino is connected to on the router or switch.

The idea I have is to blink the link light on and off.

Any help would be grateful.

John
