1.3.4 IEEE 802.1Q VLAN Application Examples

This section shows a workgroup and a shared server example using 802.1Q tagged VLANs.
For more information on VLANs, see the Switch Setup section and the VLAN Setup chapter in
this User's Guide. A VLAN (Virtual Local Area Network) allows a physical network to be
partitioned into multiple logical networks. Stations on a logical network belong to one group.
A station can belong to more than one group. With VLAN, a station cannot directly talk to or
hear from stations that are not in the same group(s) unless such traffic first goes through a
router.

1.3.4.1 Tag-based VLAN Workgroup Example

Ports in the same VLAN group share the same broadcast domain thus increase network performance
through reduced broadcast traffic. VLAN groups can be modified at any time by adding, moving or
changing ports without any re-cabling.
