You can use the storage system's command-line interface or the FilerView graphical interface to configure and manage your storage system network.
You assign initial network interface configuration values when new interfaces are created. The method you use to configure the interface depends on your preference of command-line interface (the ifconfig command) versus graphical user interface (FilerView).
An ifconfig command is included in the /etc/rc file of the root volume for each storage system interface that you specify an IP address for, during the system setup. After your storage system has been set up, the ifconfig commands in the /etc/rc file are used to configure the interfaces on subsequent storage system reboots.
You can use the ifconfig command to change values of parameters for an interface when your storage system is operating. However, such changes are not automatically included in the /etc/rc file. If you want your configuration modifications to be persistent after a reboot, you must include the ifconfig command values in the /etc/rc file.
When you use FilerView to make changes, the changes are automatically written to the /etc/rc file.
