3.5.2 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 every individual port.
With VLAN, all broadcasts are confined to a specific broadcast domain.
For VLAN Configuration, users are able to choose the following options:
1.
Disable: to disable VLAN feature.
2.
Port-based VLAN: to group ports and their mode (access or trunk)
3.
Tag-based VLAN: to assign a VID and group ports with their modes (access or trunk).
