I have a dumb question about a very dumb device. We have installed a bunch of medical devices to a location and now we need to activate their network function. Device has an embedded OS (unknown) and only shows its IP address on its network menu once connected to a network. On this location i have to provide mac addresses of the devices in order to join them to the network. Manufacturer says only way to see the mac address is to connect it to network and use arp command or check through the network. What would be the fastest way to see the mac address of this device without connecting it to the network on this location? I am considering getting a ethernet enabled mobile modem to resolve this but if there is an easier way it would be very helpful.
Sorry about lack of information on the device but getting a reply from manufacturer takes ages and replies are usually not helpful.
thanks in advance
