Setting Up Two VLANs on the Same Switch Figure 18 illustrates how you can set up a simple VLAN on the Switch using desktop connections. Figure 18 Desktop VLAN Configuration Endstations in VLAN 2 Endstations in VLAN 1 Port 1 Port 3 BaselBinaeseSlwinietcSh w2i2tc5h0 2250 Plus Port 26 Server Server in VLAN 2 in VLAN 1 If you want to add ports 1, 3, and 26 to VLAN2 (as shown in Figure 18), so that the ports on the default VLAN1 and the ports on VLAN2 cannot communicate with each other, do the following: 1 Create a new VLAN and set the VLAN ID to 2. Refer to "Creating a VLAN" for instructions. VLAN1 is the default VLAN and already exists. 2 Set ports 1, 3, and 26 to Desktop mode. 3 Click Apply. Configuring VLANs 35 Ports 1, 3, and 26 now belong to VLAN2, and will not communicate with any other ports, unless you add other ports to the VLAN or change the port configuration. Setting Up VLAN Across Two Switches This example explains how you can set up a VLAN across two Switches using uplink connections. This enables ports that are members of the same VLAN (but are on different switches) to communicate, provided that a port on each Switch is set to uplink, and that these ports are connected.
