Configuring VLANs
35
For examples on setting up VLANs, refer to 
Sample VLAN Configurations
To illustrate how you can segment network devices 
that are connected to the Switch, the following 
sample configurations are provided.
Setting Up Two VLANs on the Same Switch
 illustrates how you can set up a simple 
VLAN on the Switch using desktop connections.

If you want to add ports 7, 8, and 16 to VLAN2 (as 
shown in 
), 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 
 for instructions. VLAN1 is the 
default VLAN and already exists.
2
Set ports 7, 8, and 16 to D (desktop egress packet). 
3
Click Apply
Ports 7, 8, and 16 now belong to VLAN2, and will not 
be able communicate with any other ports, unless 
you add another port 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, pro-
vided that a port on each Switch is set to uplink, and 
that these ports are connected.
