L2 Switch - Create VLAN

VLANs are logical subgroups of a Local Area Network (LAN) created via software rather than
defining a hardware solution. VLANs combine user stations and network devices into a single
domain regardless of the physical LAN segment to which they are attached. VLANs allow
network traffic to flow more efficiently within subgroups. VLANs managed through software
reduce the amount of time in which network changes are implemented.
VLANs have no minimum number of ports, and can be created per unit, per device, per stack,
or any other logical connection combination, as VLANs are software based and not defined by
physical attributes.
VLANs function at layer 2. Since VLANs isolate traffic within the VLAN, a Layer 3 router is
needed to allow traffic flow between VLANs. Layer 3 routers identify segments and coordi-
nate with VLANs. VLANs are broadcast and multicast domains. Broadcast and multicast
traffic is transmitted only in the VLAN in which the traffic is generated.
