1.2.4 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 and VLAN Setup chapters 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.
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.
