The objectives of the Cisco LAN Switch Configuration (CLSC) exam are
taken from the Cisco web site, at the Cisco career certification and training
area. The following table shows the exam objectives covered in this chapter: Virtual local-area networks (VLANs) offer significant cost and
performance benefits for a majority of the LANs installed today. Network managers
realize these benefits as they migrate to switched LAN architectures across
the enterprise. And with VLANs working as an integral part of ATM architectures,
the concept and much of the technology have been designed into LAN-based switches
that offer similar benefits across shared-LAN backbones. In addition, end
users' applications need not change to realize these benefits: As part of
switching architecture, VLANs are invisible to end users. Finally, VLANs are
more than simply a shared hub, routing, switching, or network management solution:
The combination of all these components provides powerful segmentation and
efficient administration across the network. This chapter provides an introduction to VLANs and switched internetworking,
compares traditional shared LAN configurations with switched LAN configurations,
and discusses the benefits of using a switched virtual LAN architecture. By taking the
following steps, you can make better use of your study time: Keep your notes and the answers for all your work with this
book in one place, for easy reference. Take the quiz, and write down your answers. Studies show that
retention is significantly increased through writing down facts and concepts,
even if you never look at the information again. -
