Virtual LANs are made up of networked devices grouped together logically into separate networks. The
Switch Configuration Utility allows you to group ports on a switch to create a virtual network made up of
the devices connected to the ports. VLANs can be grouped using Port Based or 802.1Q criteria
.
Port Based - allows you to assign ports to virtual networks. Data from a port that is a member of a VLAN
group will be restricted to other members of that VLAN group. This is an easy way to partition a network
into private sub networks.
802.1Q - allows you to create virtual networks using 802.1Q criteria. When using 802.1Q VLAN
configuration, you configure ports to be a part of a VLAN group. When a port receives data tagged for a
VLAN group, the data will be discarded unless the port is a member of the VLAN group. This technique is
useful if you need to communicate with devices outside of your local network as well as still receiving data
from other ports not in your VLAN group. It requires that you know the VLAN group IDs used.
Port Based Configuration
Port Based Virtual LAN configuration assigns ports on the selected switch to a Virtual LAN Group. The
number of VLANs that can be created is limited to the number of ports on the switch. The Basic Port Based
VLAN Configuration page is designed to help you to partition your network into different segments. Ports
with the same ID are grouped into the same VLAN group. If all the VLAN groups share the same uplink to
the Internet or servers, enter 'all' in the VLAN Group field for the port that you want to use for the uplink.
Basic Port Based VLAN Configuration
To assign members of a VLAN group using Basic Port-Based configuration:
1.
Select the switch.
2.
Select VLAN. This will display the Basic Port-Based VLAN configuration page.
3.
Select Enable. A message will display asking if you want to delete previous VLAN settings.
