PREFACE

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

USING THIS GUIDE

This guide serves as a supplement to the Local Management chapter of the Cabletron Systems 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.
