Chapter 4 Examples; Example 1, Single Switch Operation - Cabletron Systems 802.1Q VLAN User Manual

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
the discussion of each example is a description of how the frames
transmitted from one user would traverse the network to its target device.

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
