4.4 VLAN

Click VLAN to configure VLAN.
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 and every individual port. With VLAN, all broadcasts are confined to a
specific broadcast domain.
