This configuration parameter sets the UDP port number the adnisd process uses to create the socket for NIS client communications. For example, the following sets the UPD port to 2555

nisd.port.udp: 2555

By default, no port number is specified. If you do not specify the port number, the operating system assigns a random port number.

Use the nisd.port.tcp and nisd.net_addr parameters to complete the NIS client socket configuration.
