Setting VLAN
A VLAN (Virtual LAN) is a group of switch ports designated by the switch
as belonging to the same broadcast domain. This feature allows
workgroups to be defined on the basis of their logical location instead of
their physical location.
VLANs also help isolate broadcast traffic and increase security.
