48 CHAPTER 4: CONFIGURING THE SWITCH
Setting Up Two VLANs on the Same Switch
Figure 31 illustrates how you can set up a
simple VLAN on the Switch using desktop
connections.
Figure 31 Desktop VLAN Configuration
If you want to add ports 1, 3, and 26 to VLAN2
(as shown in
Figure 31), 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.
