Preface

About this guide

This guide describes how to configure and manage network interfaces, virtual network interfaces (vifs), virtual LANs (VLANs), and routing on storage systems that run Data ONTAP® 7.1 software. The guide describes all Data ONTAP storage system models; however, some models do not support all of the networking interfaces. See the hardware guide for your storage system to identify which interfaces are supported on your system.

Audience

This guide is for system administrators who are familiar with operating systems that run on the Data ONTAP storage system clients, such as UNIX®, Windows 95^TM, Windows NT®, and Windows® 2000. It also assumes that you are familiar with how the Network File System (NFS), Common Interface File System (CIFS), and HyperText Transfer Protocol (HTTP) protocols are used for file sharing or transfers. This guide does not cover basic system or network topics, such as IP addressing, routing, and network topology; it emphasizes the characteristics of the Data ONTAP storage systems.

Data ONTAP user interfaces

You can perform Data ONTAP administrative procedures described in this guide using either of two kinds of user interfaces:

The command-line interface
You enter commands at the storage system command line, from one of three places:
- A system console
- A client computer that can access the storage system through a Telnet session
- A client computer that can access the storage system through a Remote Shell connection
The FilerView® administration tool's interface
You use the FilerView Web-based graphical management interface to select, view, or enter information.

In this guide, administrative procedures are described for both the command-line and FilerView interfaces, except where a particular procedure can only be performed at the command line.

The FilerView descriptions in this guide assume that you have already started FilerView in a web browser as described in the System Administration Guide.

For more information about administering a storage system using these methods, see the System Administration Guide.

Accessing Data ONTAP man pages

Data ONTAP provides manual (man) pages for the types of information listed in the following table. The man pages are grouped into sections according to standard UNIX naming conventions.

Types of information	Man page section
Commands	1
Special files	4
File formats and conventions	5
System management and services	8

Man pages can be viewed in the following ways:

At the storage system command line, by entering
```
man command_or_file_name
```
From the FilerView main navigational page
In the Command Reference Guide
Note
All Data ONTAP man pages are stored on the storage system in files whose names are prefixed with the string "na_" to distinguish them from client man pages. The prefixed names are used to refer to Data ONTAP man pages from other man pages and sometimes appear in the NAME field of the man page, but the prefixes are not part of the command, file, or services.

For more information, see the Data ONTAP man(1) man page.

Terminology and conventions

Network Appliance's storage products (filers, FAS appliances, and NearStore® systems) are all storage systems--also sometimes called filers or storage appliances.

In examples that illustrate commands executed on a UNIX workstation, the command syntax and output might differ, depending on your version of UNIX.

This guide uses the term "type" to mean pressing one or more keys on the keyboard. It uses the term "enter" to mean pressing one or more keys and then pressing the Enter key, or clicking in a field in a graphical interface and typing information into it.

Keyboard conventions

When describing key combinations, this guide uses the hyphen (-) to separate individual keys. For example, "Ctrl-D" means pressing the "Control" and "D" keys simultaneously. Also, this guide uses the term "Enter" to refer to the key that generates a carriage return, although the key is named "Return" on some keyboards.

Typographic conventions

The following table describes typographic conventions used in this guide.

Convention	Type of information
Italic font	Words or characters that require special attention. Placeholders for information you must supply. For example, if the guide says to enter the `arp -d` hostname command, you enter the characters "arp -d" followed by the actual name of the host. Book titles in cross-references.
`Monospaced` font	Command and daemon names. Information displayed on the system console or other computer monitors. The contents of files.
`Bold monospaced` font	Words or characters you type. What you type is always shown in lowercase letters, unless you must type it in uppercase letters.

Special messages

This guide contains special messages that are described as follows:

Note

Attention
An attention contains instructions that you must follow to avoid damage to the equipment, a system crash, or loss of data.
