Is there a way to find the MAC address of a switch from a PC instead of looking physically at the back of the switch. The switch has already been installed and is difficult to get to the back of it. thanks in advance. Naj

A Media Access Control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. Logically, MAC addresses are used in the Media Access Control protocol sub-layer of the OSI reference model.

MAC addresses are most often assigned by the manufacturer of a network interface card (NIC) and are stored in its hardware, the card's read-only memory, or some other firmware mechanism. If assigned by the manufacturer, a MAC address usually encodes the manufacturer's registered identification number. It may also be known as an Ethernet hardware address(EHA), hardware address, adapter address, or physical address.

Hope this information will help you.
