I suspect you're looking at Ethernet full-duplex flow control. This feature allows the receiver to tell the sender to suspend (or pause) its transmission. This allows the receiver to process the received data avoiding drops.
Not all Ethernet duplex devices support this capability. Often you need to tell the device to negotiate the option.
Some Ethernet devices can provide a similar capability when using half duplex. What happens is the receiver makes the wire appear busy to the sender.
when that flow control is on I couldn't ping the server even from switch itself. engineer had did something after that server was reachable. then I checked I noticied only that flow control was turned off.
The engineer told just turned off the speed negotiation. I dont understand what is that. Can you please shed a light on this for me.
