ProSafe Plus Switch Utility VLAN Overview Virtual LANs are made up of networked devices that are grouped logically into separate networks. You can 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. The VLAN tab has the following options: • Port Based. Allows you to assign ports to virtual networks. Data from a port that is a member of a VLAN group is restricted to other members of that VLAN group. This feature provides 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 is discarded unless the port is a member of the VLAN group. This technique is useful for communicating 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. Virtual LAN Configuration 26

VLAN Overview
Virtual LANs are made up of networked devices that are grouped logically into separate
networks. You can 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.
The VLAN tab has the following options:
•
Port Based
. Allows you to assign ports to virtual networks. Data from a port that is a
member of a VLAN group is restricted to other members of that VLAN group. This feature
provides 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 is discarded unless the port is a member
of the VLAN group. This technique is useful for communicating 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.
