There is a large number of network-related settings that can be customized in Symbol.
The easiest way to change them is by using Symbol Bootstrap’s custom presets (read Using Symbol Bootstrap): Put the settings in a YAML file and pass it to symbol-bootstrap config using the -c parameter.
These settings can also be directly provided to catapult-client through .properties files. The header of each of the tables below indicates which file contains that table’s properties.
Note
For node-related properties, read the Configuring node properties guide.
