I have a 6 port unmanaged switch feeding my ESW520 24 port switch. I am able to see only 1 of the 5 devices connected to the unmanaged switch. I would appreciate any recommendations of settings that could possibly be causing this anomaly. I have factory reset the ESW520 and can still only see the one device. If I connect the unmanaged switch to a laptop instead of my ESW520 I am able to see all devices on the unmanaged switch.
