Overview

5.1.1 VLAN

Virtual LAN (VLAN) logically groups users by their functionality instead of physical
location. VLAN uses software to configure logical topologies on top of the physical
network infrastructure. Users grouped into one VLAN may be located on different floors
or in different buildings. However, all users on one VLAN can communicate with each
other as if they were all on the same physical LAN.
The same concept extends to a wireless network. Wireless clients can be grouped into
wireless sub-networks. A client can access the network by connecting to an AP which
supports its assigned VLAN (see Figure 5.1).
VLANs provide many benefits:
• VLANs increase performance by limiting broadcast traffic for both wired and
wireless networks.
• VLANs improve manageability by providing an easy, flexible way to modify logical
groups in changing environments. When a
location, it can stay on the same VLAN without any
• VLANs increase security options. Broadcast traffic is only broadcast within the
VLAN. This allows the network administrator to segment users requiring access to
sensitive information into VLANs separate from the rest of the community.
