This configuration is to let the node know how long it should wait before it ends a test script session when the browser seems to hang. After this time, the node will abort the browser session and start with the next waiting test script. The configuration parameter for this is browserTimeout. The command to specify that is as follows:

java -jar selenium-server-standalone-3.12.0.jar -role node -hub http://192.168.0.1:1111/grid/register –browserTimeout 60

So, these are the some of the configuration parameters that you can specify at the node's end to have better control over the Selenium Grid environment.
