5. Application Examples
5.1. VLAN application used with switch
VLAN is a simple solution to protect your network against broadcast storming by creating
segments based on Layer2 Ethernet information and avoiding the complexity and the heavy
processing requirements of Layer3 IP based routers.
As a result, each group of stations connected to separate Segmented Ports forms different
isolated Broadcast Domain. The Broadcast Sharing Ports should be used to connect servers
and other common services, such as Internet access, that are used by all the stations connected
to the different Segmented Ports.
Virtual LAN, or VLAN, is generally defined as broadcast domain. It can be viewed as a group
of end nodes, possibly on different physical network segments, which can communicate with
each other.
