13.12 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 13-10 shows the initial state of the switch.

13.12.1 Solving the Problem
To set up this switch, users will be assigned to two new VLANs, red stations to the Red VLAN,
and blue stations to the Blue VLAN. The information below describes how the switch is
configured to create these two VLANs and how users are assigned to them.
1. The switch is set for 802.1Q operation.
2. VLAN ID 2 (Red VLAN) and VLAN ID 3 (Blue VLAN) are created using the Static VLAN
Configuration screen. The filter database FDB ID 2 and FDB ID 3 are automatically assigned to
the Red VLAN and Blue VLAN, respectively.
3. The Egress type for each port associated with a VLAN is set using the Static VLAN Egress
Configuration screen. In this example, the settings are as follows:
• For the Red VLAN
Ports 1, 2, and 3; Egress; UNTAGGED
• For the Blue VLAN
Ports 4, 5, and 6; Egress; UNTAGGED
