Configuring VLANs 35
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
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.
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 configu-
ration.
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, pro-
vided that a port on each Switch is set to uplink, and
that these ports are connected.
