Figure 53 - 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).
As you can see the 245U-E supports flexible VLAN functionality such that any of the available interfaces can have
membership
to particular VLAN(s) by assigning membership to one or more VLAN’s groups, virtually any possible
topology can be achieved.
Shown below is the configuration for the Multi VLAN example above. You will see there are four groups configured, one
for management and one for each of the VLAN ID’s. The Management group only has the untagged Ethernet Interface
configured which means only untagged device on the same IP subnet can access the modules configuration.
