Configuring VLANs
VLANs are logical subgroups within a Local Area Network (LAN), which combine user stations, and network devices into a single unit, regardless of
the physical LAN segment to which they are attached. VLANs allow network traffic to flow more efficiently within subgroups. VLANs use software to
reduce the amount of time it takes for network changes, additions, and moves to be implemented.
VLANs have no minimum number of ports, and can be created per unit, per device, or through any other logical connection combination since they
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 working at a protocol level is required 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.
VLAN tagging provides a method of transferring VLAN information between VLAN groups. VLAN tagging attaches a 4-byte tag to packet headers.
The VLAN tag indicates to which VLAN the packets belong. VLAN tags are attached to the VLAN by either the end station or the network device.
VLAN tags also contain VLAN network priority information.
The NETGEAR FS700TS-series Switch supports up to 128 active VLANs.
