PREFACE

Welcome to DIGITAL's 802.1Q VLAN User's Guide. This guide
introduces and describes DIGITAL's implementation of the IEEE 802.1Q
draft standard for 802.1Q Virtual Local Area Network (VLAN)
technology, and the VLAN Local Management screens used to configure
DIGITAL's products used in 802.1Q VLAN environments.

USING THIS GUIDE

This guide serves as a supplement to the Local Management chapter of
the DIGITAL's user's guides for devices that support 802.1Q VLANs.
Read Chapter 1 and Chapter 2 first to gain an understanding of VLANs,
the associated terminology, and the process for configuring VLANs on a
switch. Look at the examples in Chapter 4 to see how VLANs can be
created and changed using the existing network infrastructure in a
building and how the switch handles the frames while they make their
way through the networks shown in the examples. Chapter 3 describes the
VLAN Local Management screens and provides a quick walkthrough on
how to use them to configure VLANs in a switch.

STRUCTURE OF THIS GUIDE

This guide is organized as follows:
Chapter 1, Virtual Local Area Networks, presents the basic concepts of
VLANs, including their benefits and uses. This chapter also provides
information about how to obtain additional help if needed.
Chapter 2, VLAN Operation, describes the operation of an 802.1Q
VLAN, the steps necessary to prepare an 802.1Q VLAN aware switch for
VLAN operation, and examines the operation of an 802.1Q VLAN
switch.
Chapter 3, VLAN Configuration, describes how to set up the switch for
local and remote management, shows the Local Management screens
used in 802.1Q VLAN configuration and explains their use.
Chapter 4, Examples, offers examples of 802.1Q VLANs and explains
how network transmissions are treated by the components of each VLAN.
