Just forget about ICX switch 7150 for a minute and only consider Unleashed network.
On Unleashed GUI under Clients, you can see two types of client.
1- Client connected to APs wirelessly are called "Wireless Clients". 2- Client connected to APs on AP's eth ports are called "Wired Clients" (Please note that such wired client connected behind an AP will only show in Unleashed GUI, if APs port is configured for 802.1X authentication).
As per above, client connected behind AP's eth ports are Wired Client, not the client connected to ICX switch.
