4 Configuring VLANs
In a flat bridged network, a broadcast domain is confined to a single LAN segment or even a specific
physical location, such as a department or building floor. In a switch-based network, such as one
comprised of Alcatel-Lucent switching systems, a broadcast domain—or VLAN— can span multiple
physical switches and can include ports from a variety of media types. For example, a single VLAN could
span three different switches located in different buildings and include 10/100 Ethernet, Gigabit Ethernet,
802.1q tagged ports and/or a link aggregate of ports.
