I just noticed that you check FDB on switch using object tools. What is shown if you use Topology -> Switch forwarding database context menu on switch?

Ah, going that route it shows all of the MAC addresses.  Although the "Find IP Address" tool still shows the indirectly attached port.

So the problem is not with reading FDB, but with internal logic. Can you run manual topology poll (from Poll->Topology context menu) on Cisco switch and your workstation and show results?

From the switch:

And from the node object that is my workstation:

I hope that's what you were looking for.

Do you see correct MAC address on workstation's interface? If yes, is this MAC address present in FDB table you see in console and is it the only MAC address on a port?

Here is a CSV export of the FDB entry for the workstation:

"MAC Address","Port","Interface","VLAN","Node","Type"
"00:23:24:6C:89:04","95","[0]","500","Test Workstation","static"


The workstation is actually on Gi2/0/39.  My workstation is plugged into a Polycom IP phone, so Gi2/0/39 has both MAC addresses in the mac address table.  The port is an access port (we don't currently separate voice into a dedicated VLAN).

Here's the entry for the phone:

"MAC Address","Port","Interface","VLAN","Node","Type"
"00:04:F2:9D:B0:F2","95","[0]","500","","static"
