Just as the title says, I'm looking for a way to collect the MAC address of the device that's on the other end of an Ethernet wire from my Laptop. The device on the other end is most likely a switch, though I can't be for sure. I'm trying to map out the physical connections in the network so we know what device connects to what...as it stands right now, its a nebulous cloud of ideas with no concrete information. I thought of using Wireshark but, assuming it's a switch on the other end, I'll just get a flood of packets with a couple dozen MACs and no way of knowing which belongs to the switch.
