214  IBM System Storage N series Hardware Guide
16.1  Administration methods
The following methods can be used to administer an N series storage system:
ň° Command-line interface (CLI)
ň° N series System Manager
ň° OnCommand
16.1.1  FilerView interface
Earlier versions on the N series controllers supported a built-in web management interface 
called 
FilerView. This interface is still available for systems that are running ONTAP 7.3 or 
earlier, but was removed in ONTAP 8.1.
To access a pre-8.1 N series through FilerView, open your browser and go to the following 
URL:
http://<filername or ip-address>/na_admin 
To proceed, specify a valid user name and password.
16.1.2  Command-line interface
The CLI can be accessed through Telnet or a Secure Shell (SSH) interface. Use the help 
command or enter a question mark (?) to obtain an overview of available commands. 
Enter help <command> for a brief description of what the command does.
Tip: By default, the FilerView interface is unencrypted. Enable the HTTP/S protocol as 
soon as possible if you plan to use FilerView.
Do not use FilerView. Instead, use the CLI or OnCommand System Manager to perform 
administrative tasks
