As we saw earlier, when we register a node with a hub, by default, the node is shown as supporting five instances of the Firefox browser, five instances of the Chrome browser, and one instance of Internet Explorer, irrespective of whether the node actually supports them.

java -jar selenium-server-standalone-3.12.0.jar -role node -hub http://192.168.0.1:1111/grid/register -browser browserName=firefox -browser browserName=chrome -browser browserName=safari

The Grid Console looks like this:
