VLAN is for Bridge mode only.
VLAN (Virtual Local Area Network) allows a physical network to be partitioned into multiple logical networks. Devices
on a logical network belong to one group. A device can belong to more than one group. With VLAN, a device cannot
directly talk to or hear from devices that are not in the same group.
With MTU (Multi-Tenant Unit) applications, VLAN is vital in providing isolation and security among the subscribers.
When properly configured, VLAN prevents one subscriber from accessing the network resources of another on the
same LAN.
VLAN also increases network performance by limiting broadcasts to a smaller and more manageable logical broadcast
domain. In traditional switched environments, all broadcast packets go to each every individual port. With VLAN, all
broadcasts are confined to a specific broadcast domain.
User can choose three types of VLAN: 802.1Q Tag-Based VLAN and Port-Based VLAN. You can also set Disable the VLAN
function.
The VLAN Setup screen changes depending on whether you choose 802.1Q Tag-Based VLAN type and Port Based VLAN
types in this screen.
The IEEE 802.1Q defines the operation of VLAN bridges that permit the definition, operation, and administration of
VLAN topologies within a bridged LAN infrastructure.
