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.
Tungsten's melting point of 3422 Â°C is the highest of all metals and second only to carbon (3550 Â°C) among the elements. This is why tungsten is used in rocket nozzles and reactor linings. There are refractory ceramics and alloys that have higher melting points, notably $\ce{Ta4HfC5}$ with a melting point of 4215 Â°C, hafnium carbide at 3900 Â°C and tantalum carbide at 3800 Â°C. Carbon cannot be used to hold molten tungsten because they will react to form tungsten carbide.
