Examples
This chapter provides examples of how VLAN aware SmartSwitches can be configured to group
users at the port level to create VLANs in existing networks. Each example presents a problem and
shows how it is solved by configuring the switches using the VLAN Local Management screens.
The actual procedures and screens used to configure a VLAN aware switch are covered in
Chapter 3 , VLAN Configuration . Also provided in the discussion of each example is a
description of how the frames transmitted from one user would traverse the network to its target
device.
4.1 EXAMPLE 1, SINGLE SWITCH OPERATION
This first example looks at the configuration of a single Ethernet switch for VLAN operation. In
this example, two groups of three users are to be assigned to two VLANs to isolate them from one
another. The blue users (B1, B2, B3) are to be kept completely separate from the red users (R1, R2,
R3).
Figure 4-1 shows the initial state of the switch.
