MySQL -> X protocol port

 Port 3306 is the default port for the classic MySQL protocol (port), which is used by the mysql client, MySQL Connectors, and utilities such as mysqldump and mysqlpump. The port for X Protocol (mysqlx_port), supported by clients such as MySQL Shell, MySQL Connectors and MySQL Router, is calculated by multiplying the port used for classic MySQL protocol by 10. For example if the classic MySQL protocol port is the default value of 3306 then the X Protocol port is 33060.
