USB-C - Ethernet Adapter Cloning Unmanaged Switch MAC

[Enfield]

Hi,

I have a USB-C - Ethernet adapter that is cloning the MAC address of an unmanaged switch. To do it, I simply plug an Ethernet cable into the adapter; the USB end isn't even plugged in to any device. I can then ping the IP address assigned and get a response. Unplugging the adapter, it still pings as its obviously pinging the switch, however an unmanaged switch obviously shouldn't have an IP address.

This to me seems very strange or is this normal behaviour? The device is called "uni".

If it is normal, would this have any negative effect on the network?

An unmanaged switch doesn't have a MAC address (or IP address) of its own.

Morning,

I thought I was reading the situation correctly last night, but today I can see that the MAC address has appeared. It is on the bottom of the physical switch. I didn't realise but its not actually unmanaged, its a Netgear GS105PE with basically functionality.

How do I delete this thread as its just a waste of time to read now haha
