I have an old Netgear JGS524E switch. I am trying to map out where all the wires go. I have a remote roku device that gives me the assigned IP and MAC address, and it says it is a wired connection. However, the switch only has a rudimentary web gui, and there is no show mac-address function. It would take some effort to remove the roku/TV from the wall to disconnect the network cable, so I was hoping there is some clever way to find out which switch port that roku device is connected to.

I tried a process of elimination to map all the other lines back to the switch, and all of the lines are accounted for...which means the roku is not connected to the wired switch. But the interface says it is connected to a wired port, so I am at a loss to say which port goes to that device. The roku works even when I turn off the wifi routers....

Thanks!
