The name-service/switch SMF service is a configurable selection service that enables you to specify which name service or source to use for each type of network information.
The service's configuration settings that used to be stored in the /etc/nsswitch.conf file are now property values of the SMF service. You must configure nsswitch settings through SMF rather than the file. The main commands to use are svccfg and svcadm. For example, to display current property settings of the name service, you would type:
$ svccfg -s name-service/switch listprop config
