Editing configuration files
You can edit the configuration files, such as /etc/hosts.equiv, /etc/nsswitch.conf, and /etc/netgroup, from the Network Files window.
About this task 
Data ONTAP uses the /etc/hosts file to resolve host names to IP addresses. If you use a Domain Name System (DNS) server or a Network Information Service (NIS) server, the order in which they are used is determined by the /etc/nsswitch.conf file. The /etc/netgroup file defines network-wide groups used for permission checking when fielding requests for remote mounts, remote logins, and remote shells. For remote mounts, the information in the netgroup file is used to classify machines. For remote logins and remote shells, the file is used to classify users.
