The Managed Switch Port Mapping tool communicates with managed Ethernet network switches using SNMPv1/v2c/v3 and discovers the MAC and IP addresses (IPv4 if available) of devices attached to the physical port jacks on the front of the switch. The software is designed to be installed on a hard drive running a Microsoft Windows® 11 or 10 operating system. This is an upgrade license of the installed version of the Managed Switch Port Mapping Tool version 2. You will be sent a permanent unlock code by email.
