40 CHAPTER 4: CONFIGURING THE SWITCH
The Switch will only forward a frame to ports that are
members (tagged or untagged) of the VLAN to which
the frame is assigned. If the port is an untagged
member, the egress frame will be stripped of the
VLAN tag and forwarded as untagged. However, if
the port is a tagged member, the egress frame is
forwarded as tagged.
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
Figure 32
illustrates how you can set up a simple
VLAN on the Switch using desktop connections.
Figure 32 Desktop VLAN Configuration
If you want to add ports 1, 3, and 26 to VLAN2 (as
shown in Figure 32
), 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.
