Switch Port Mapper lets you see exactly what's connected to every port on your switches or hubs without manual tracing. It remotely discovers devices connected to switch ports and maps them to their corresponding MAC and IP addresses, giving you a complete view of your network. Finding which switch and port an end user IP is connected to in a large LAN with multiple switches involves a series of steps using network tools and commands. Here's a step-by-step guide to trace the IP: 1. Identify the MAC Address of the IP First, you need to find the MAC address associated with. When we do an IP scan it shows it as a Cisco device, but we have no idea where the physical location of the device is! We went through all of the cisco devices we know of and none of them match the MAC address that is together with the device on the IP scan. I found out that this is the correct way •3. You will get the port # (if it is a trunk port, go to next switch to check ) But in core switch,there is no.
