VLAN Operation and Network Applications 12-21
This effectively completes the configuration of a single VLAN, assigning it to a port, and
configuring the switch to forward the frames received on that port to a trunk port. The trunk port in
turn forwards the frames as tagged to another switch.
You can now use the VLAN Classification Configuration and Port Protocol Configuration screens
to transmit frames according to classification rules and associated ports, as described in Chapter 7.
12.11 EXAMPLES
The following sections provide some 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 7. 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.
12.12 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 12-10 shows the initial state of the switch.
