Figure 59 - Example 1 Configuration
Example 2 – Multiple Wireless Interfaces
Another very desirable VLAN configuration for a wireless device is to support multiple virtual wireless networks. For
example consider a corporate facility where separate networks may be provided for a) permanent staff; b) guests; and c)
production network. Each of the three different virtual networks can be setup using different encryption keys, etc, to
enhance security. The setup is illustrated below:
Figure 60 - VLAN Example 2
The module is configured with three wireless interfaces, the first one is the normal wireless interface found on the Network
page (wi0), the second (wi1) and third (wi2) are virtual interfaces created on the Repeaters page. Each interface is
configured as an Access Point and can be setup with unique SSID’s and Encryption settings, etc. In this example all three
wireless interfaces are untagged, so that devices joining each of the networks need not be VLAN aware.
Untagged data from each of the wireless interfaces are individually bridged with one of the three VLAN aware virtual
interfaces “VLAN ID 10”, “VLAN ID 20” and “VLAN ID 30” on the physical Ethernet Interface which forms a VLAN trunk.
Untagged data transferred via the first Wireless Interface (wi0) is internally bridged with the virtual interface “VLAN ID 10”,
likewise untagged data transferred via the other two WDS repeater interfaces (wi1 & wi2) are bridged respectively with
“VLAN ID 20”and “VLAN ID 30”. The unique VLAN tags are used for corresponding Ethernet data (so that the Ethernet
port becomes a VLAN trunk).
