It is a little bit more complicated than that depending on what you mean by Layer 3. If by layer 3 you mean routing then yes you are correct.
But IP addresses "live" at layer 3 and IP addresses are always involved when we talk about mac-addresses/IP addresses. What i mean is
Host1 = 192.168.5.10/24
Host2 = 192.168.5.11/24
They are both on the same subnet. Host1 wants to send a packet to Host2. It needs it's mac-address to do this. But first Host1 needs to work out if Host2 is on the same subnet and it does this by using IP addresses ie.
basically, the situation is this, we have a server that talks to devices via mac address only, no ip involved, but we want to put the server in another vlan and change the ip address, but it will then lose the comms to these devices as the mac will no longer be visable in that vlan, is there anything I can do here ?
