Figure 24: VLAN Overview
In virtual topological networks, the network devices may be located in diverse places around the
LAN-such as in different departments, on different floors or in different buildings. Connections
are made through software. Each network device is connected to a hub, and the network
manager uses management software to assign each device to a virtual topological network.
Elements can be combined into a VLAN even if they are connected to different devices.
VLANs should be used whenever there are one or more groups of network users that you want
to separate from the rest of the network.
In Figure 22
, the switch has three separate VLANs: Sales, Engineering, and Marketing (Mktg).
Each VLAN has several physical ports assigned to it with PC's connected to those ports. When
traffic flows from a PC on the Sales VLAN for example, that traffic is only forwarded out the
other ports assigned to that VLAN. Thus, the Engineering and Mktg VLANs are not burdened
with processing that traffic.
