Free Download SoftPerfect Switch Port Mapper 3.1.10 Portable Fast Links | 10.6 Mb
The SoftPerfect Switch Port Mapper tool works with managed network switches and reports what is connected to switch ports, and which ports are not connected. For every connected port, the port mapper lists the MAC address, IP address and host names of the computers associated with that port.

Additionally, the software can display each client's network card vendor, port speed, and the counters of erroneous and discarded frames for every port. This can be of good assistance when troubleshooting network connectivity issues.
