3.6.5 Port Based VLAN
Figure 3-24 Features Menu, Port Based VLAN tab
Port Based VLAN is a simple way to designate a specific VLAN association for each port by itself. This
option is useful in managing sensitive ports that should not be accessible to other ports, or limited ports
that should only be able to access the uplink port.
The default setting for the Port Based VLAN allows every port access to all other ports — basically,
normal switch operation.
To modify the Port Based VLAN,
1. Click on the Features icon and select from the Features menus. Port Based
VLAN and VLAN Mode tabs.
2. In the VLAN Mode tab, select Port Based VLAN Enabled.
3. In the Port Based VLAN tab, go to the port line you wish to modify (Horizontal
lines) and uncheck ports that the modified port should not be able to access.
4. Click Apply, and on the confirmation box click Yes.
NOTE: Port Based VLAN cannot be active when 802.1q VLANs are active. To select one
or the other, go to the VLAN Mode tab.
3.6.6 Transparent VID
Figure 3-25 Features Menu, Transparent VID tab
Transparent VID is a further enhancement to VLAN tag configuration. This function is useful to support
an application or device that does not accept tagged frames on an otherwise tagged network.
The Transparent VID function defines a unique "transparent" VID to selected trunk port(s). If the Egress
Tag Insert is selected on those trunk port(s) and Transparent VID is enabled, a tag will not be added
to frames bearing the "transparent" VID when egressing. Those frames will be transmitted untagged
while all other frames, bearing other VIDs, will be transmitted tagged.
