5.4 VLANs

A 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 VLANs, a device cannot directly talk to or hear from devices that are not in the
same group(s); the traffic must first go through a router.
In MTU (Multi-Tenant Unit) applications, VLANs are vital in providing isolation and security among the subscribers. When properly configured,
VLANs prevent one subscriber from accessing the network resources of another on the same LAN, thus a user will not see the printers and hard
disks of another user in the same building.
VLANs also increase network performance by limiting broadcasts to a smaller and more manageable logical broadcast domain. In traditional
switched environments, all broadcast packets go to each and every individual port. With VLAN, all broadcasts are confined to a specific broadcast
domain.
Note:
VLANs are unidirectional; they only govern outgoing traffic.
Use the VLAN sub-menu to configure which ports can communicate with other ports. Use the
