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.
Glass transition temperatures are kind of like melting points, but some materials have a glass transition temperature and a melting point. Some initial casting about on the internet finds that rhenium and tungsten have melting points at about 3400 C, and Hafnium Carbide claims to be 'one of the highest' at 4100 Kelvin.
