I have a query regarding Link Fault Signal Function.

What determines a local/remote fault on a port when it goes down.

Am I to assume that a local fault means the switch caused the port to go down and a remote fault, the client caused the port to go down?

The concepts guide is non existent when it comes to explaining the reasoning's for this.

Look forward to your response

Hello Ian

This is part of the IEEE 802.3ae-2002.  If you search on that site it will explain the difference.  Essentially it is whether the port detects the link fault on its TX or RX pair.

Let me know if that helps.
