Broadcast mode is the simplest method for establishing a NIS client. When you start the nis/client SMF service, the service runs the ypbind command, which searches the local subnet for a NIS server. If a subnet is found, the ypbind command binds to it. This search is referred to as broadcasting. If no NIS server exists on the client's local subnet, the ypbind command fails to bind and the client machine cannot obtain namespace data from the NIS service. See How to Configure a NIS Client by Using Specific NIS Servers.
