You may need to go to the MAC address table in order for you to see the MAC address of each port. Select Switching > Address Table > Basic > Address Table. Have you tried to do a factory reset? Please also try upgrading the firmware to its latest version. You may download the firmware here.

Of course the address table is where I was seeing that there was no MAC for these Link Up ports. I have about a dozen ports showing Link Up. Most of those show up in the MAC address table. Some show up a couple of times if they go to multiple devices. But a couple of the ports showing as Link Up don't show in the address table at all. Yes, I've set it to Show All. One port has only ever had traffic as Packets Transmitted (in Port Statistics) but the other has had both Packets Transmitted and Packets Received (all without errors). How can that possibly be if the switch doesn't know the MAC? Is this an error of the display of the address table? Or something else?
