Configuring Virtual LANs (VLANs)

The L2 Switch > VLAN window displays the settings for creating and adding a
VLAN to the router.
VLANs are logical subgroups of a 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 are software based and not defined by physical attributes. They have no
minimum number of ports and can be created per unit, per device, per stack, or
any other logical connection combination.
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 coordinate with VLANs.
VLANs are broadcast and multicast domains. Broadcast and multicast traffic is
transmitted only in the VLAN in which the traffic is generated.
The WRVS4400N router supports up to 4 VLANs, including the default VLAN.
