Is there a way to send some (non-broadcast) packets out on an Ethernet interface that doesn't have an IP address assigned to it? Thus allowing me to see which light blinks on the network switch?
The issue is I have a server with three network interfaces. I know which three switch ports they are connected to, but not which interface name goes with each physical jack on the server. If they all had addresses, I could just use ping, but I was hoping to figure out which is which before I configure them. The back of the server is tough to get to, too. I'd have to move the rack. Otherwise, I could just use
Edit: This is on a Linux server. Ubuntu, to be specific, though I imagine this wouldn't be distro-specific.
