You can use SmartPort macros to enable features and settings based on the location of a switch in the network and for mass configuration deployments across the network. Each SmartPort macro is a set of CLI commands that you define.
The metal with the highest melting point is Tungsten (W) at 3410 degrees Celsius (6170 degrees Fahrenheit). However, technically Carbon has a higher melting point, though not under normal atmospheric conditions. This is because it sublimates (turns directly from a solid to a gas) at 6740 degrees Fahrenheit under normal circumstances.
but it can be melted in the absence of air (or in vacuum) at a very very very high temperature. Since the melting point of diamond, the highest melting point required of any mineral -- 3820 degrees Kelvin -- a melted diamond is uncommon. Read more about the mineral diamond, below. Not humanly possible, but if temperatures reach (I will get back to you) it is possible. It is pressure dependant.
