To set up the configuration shown in

Figure 33

:

1 Configure the VLANs

Use the VLAN Setup page of the web interface to define VLAN 2 on the
Switch. VLAN 1 is the default VLAN and already exists. Do not add the
ports to the VLAN using this screen. For more information about creating
a VLAN, see

“Configuring VLANs

on

page 83

.

2 Edit the Port settings

Use the Untagged VLAN listbox on the Port Setup page of the web
interface to:

a Place ports 1, 3 and 13 of the Switch 1100 in VLAN 1.

b Place ports 10, 12 and 24 of the Switch 1100 in VLAN 2.

For more information about editing the port setup, see

“Configuring a

Port”

on

page 59

.

3 Check the VLAN membership

Return to the VLAN setup page of the web interface to check VLAN 1 and
VLAN 2. The relevant ports should be listed in the VLAN Members listbox.

Simple Example:

Untagged

Connections with

Hubs

In a slightly larger network the switch port may be connected to a hub
rather than a single endstation to provide more connections to the VLAN.
You can still use untagged connections, as data is not being passed
between switches and the VLANs are still contained within a single
switch.

The example shown in

Figure 34

illustrates a Dual Speed Hub 500 and a

Switch 3300 connected using untagged connections. The Switch 3300
has a SuperStack II Switch Layer 3 Module installed, which allows it to
provide Layer 3 switching which means that traffic can be passed
between VLAN 1 and VLAN 2. On the Switch 3300, ports 1 and 14
belong to VLAN 1, and ports 2, 6 and 24 belong to VLAN 2. VLANs 1 and
2 can communicate using the Layer 3 Module.
