The term “VLAN” is used to refer to a collection of devices that communicate as if they
were on the same physical LAN. Any set of ports (including all ports on the switch) is
considered a VLAN. LAN segments are not restricted by the hardware that physically
connects them. The segments are defined by flexible user groups you create with the
command-line interface.
