Configuring VLANs 47
Setting Up Two VLANs on the Same Switch
Figure 30 illustrates how you can set up a simple VLAN
on the Switch using desktop connections.
Figure 30 Desktop VLAN Configuration
If you want to add ports 1, 3, and 26 to VLAN2 (as
shown in Figure 30), 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
“Setup” for instructions. VLAN1 is the default VLAN and
already exists.
2 Set ports 1, 3, and 26 to associate with the Untagged
membership in VLAN2.
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
configuration.
Setting Up VLAN Across Two Switches
This example explains how you can set up a VLAN
across two Switches using Tagged ports. 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 Tagged, and that these ports
are connected.
