Chapter 3: Virtual LAN Configuration
ProSafe Unmanaged Plus Switch Configuration Utility User Guide
VLAN Overview
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.
