Server Configuration - CUCM Administration > System > Server. There is a MAC address field which I have always left blank. The CUCM Admin Guide states "If you plan to move the server periodically to different locations on the network, you must enter the MAC address, so other devices on the network can always identify the server."
Can someone explain the benefit of entering the MAC address here or the downside of not entering it if you move the server to another switch? I don't see how it would make a difference.
