Wireless Distribution System (WDS)
The IEEE 802.11a standard defines a WIreless Distribution System (WDS) for
connections between wireless bridges. The outdoor wireless bridge uses WDS to
forward traffic on links between units. When using WDS, only wireless bridge units
can associate to each other. A wireless client cannot associate with any unit in a
wireless bridge network.
To set up a wireless bridge link you must configure the WDS forwarding table by
specifying the wireless MAC address of the bridge to which you want to forward
traffic. For a Slave bridge unit, you need to specify the MAC address of the wireless
bridge unit at the opposite end of the link. For a Master bridge unit, you need to
specify the MAC addresses of all the Slave bridge units in the network.
Mode – The wireless bridge software operates in a Slave or Master mode depending
on the unit hardware (the mode is not configurable):
• Master Mode: In a point-to-multipoint network configuration, only one wireless
bridge unit must be a Master unit (all others must be Slave units). A Master wireless
bridge provides support for up to 16 MAC addresses in the WDS forwarding table.
The MAC addresses of all other Slave bridge units in the network must be
configured in the forwarding table.
• Slave Mode: A Slave wireless bridge provides support for only one MAC address
in the WDS forwarding table. A Slave bridge communicates with only one other
wireless bridge, either another Slave bridge in a point-to-point configuration, or to
the Master bridge in a point-to-multipoint configuration.
Port No (Master bridge only) – The wireless port identifier (1 to 16).
