Hi guy, I have a customer in the company who has static network /I hope thats the correct term/. They have no DHCP server, and every device`s MAC address has to be authenticated in the network first.
We are exchanging there our old devices to new ones. That means the IP address of the devices has to be always the same as the old device, just the MAC address is new.
When I installed the new device it gets no internet connection and they said they can see it has been plugged in to the switch but they cannot ping it. The old device could be pinged and had internet connection.
Two things are for sure: they have authenticated the MAC address of the new device and the second is that all network properties of the new device is the same as the old one /IP, Netmask, Default gateway/.
I have advised them to clear the ARP table maybe the old entry for the old device preventing the new one to connect, but they said there is no ARP entry for the old device nor the new one.
Do you have any idea what could prevent the device to connect? I would very welcome a little help!
