VLAN
The term VLAN is used to refer to a collection of devices that communicate as if they are 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 CLI.
