VLAN Configuration Examples 67

2Add ports to the VLANs

Add ports 10, 11 and 12 of the Switch as untagged members to VLAN 2.

Using 802.1Q Tagged In a network where the VLANs are distributed amongst more than one Connections Switch, you must use 802.1Q tagged connections so that all VLAN traffic

can be passed along the links between the Switches.

The example shown in Figure 19 illustrates two Switch units. Each switch has endstations and a server in VLAN 1 and VLAN 2. All endstations in VLAN 1 need to be able to connect to the server in VLAN1 which is attached to Switch 1 and all endstations in VLAN 2 need to connect to the server in VLAN2 which is attached to Switch 2.

Figure 19 VLAN configuration example: 802.1Q tagged connections

To set up the configuration shown in Figure 19:

1Configure the VLANs on Switch 1

Define VLAN 2. VLAN 1 is the default VLAN and already exists.

2Add endstation ports on Switch 1 to the VLANs

Place the endstation ports in the appropriate VLANs as untagged members.
