802.1Q VLAN User’s Guide ix
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.
