We are rearrange and reconfiguring the switches and this time around we decide to move all non-client devices to a separate switch (like everyone does). To do that, I have to first find what devices are connected to what ports.
We have a few door access card terminals and those are going to be moved, but their port numbers were not documented when they were installed 10+ years ago. It is impossible to trace the cable as the terminals were permanently installed on the wall, it will take destructive means to remove it (security measures? idk, ask Admin).
We have the IP addresses of the devices. We can find their respective MAC addresses and IP addresses by doing a show arp. However, those devices never shows up when doing show mac address-table.
What can I do except resorting to tracing the cable?
