Lets say Access Point 1 of BSS1 wants to communicate with Access Point 2 of the BSS2 in its vicinity. In such a scenario, both
the Access Points 1 and 2, register each other's MAC address. Once registered, a WDS link is established between BSS 1 and
BSS 2. The data transmission over the WDS link follows a four address format, which contains 1) MAC address of the source,
2) MAC Address of the destination, 3) MAC Address of the transmitting AP device, 4) MAC Address of the receiving AP
device.
WDS supports two modes:
1. WDS - Legacy Mode: In this mode, a WDS link can be established between two Legacy AP devices supporting the
IEEE 802.11 a/b/g modes, without serving the 11n authentication functionality while establishing the WDS link. This
mode supports the WEP encryption type to secure the data.
Using this mode we can connect AP-800 / AP-8000 with legacy products AP-700 / AP-4000. To establish a WDS link
in this mode, configure both the VAPs in WDS-Legacy mode.
2. WDS - 11n Mode: In this mode, a WDS link can be established between two BSS supporting the IEEE 802.11n a/ng
modes, serving the association and authentication functionalities. This mode supports the AES (128 bit) encryption
type to secure the data. In WDS-11n mode, each VAP can be configured in either:
a. WDS END - A mode: The VAP enabled in this mode will act as a WDS enabled AP device and performs standard
AP functionality.
b. WDS END - B mode: The VAP enabled in this mode will act as a WDS enabled Station (STA) and perform the
functions of a station/client.
By using this mode, we can connect only to AP-800 / AP-8000. To establish a WDS link in this mode, one VAP should
be set to "WDS-END-A" and other VAP should be set to "WDS-END-B".
: When the WDS link is DOWN, the following behavior is expected:
• If WDS-ENDA and VAP-AP are on same radio, then the VAP-AP transmits the beacons.
• All the VAPs on the same interface (radio) as WDS-END B, stop transmitting the beacons.
• The VAPs on an interface (radio) other than WDS-END B, transmit the beacons.
By default, the WDS feature is disabled on the device. To enable WDS on the device, follow the following steps:
1. To configure VAP in WDS - Legacy Mode, select the Operational Mode to 802 11a or 802 11g and to configure
the VAP in WDS - 11n Mode, select the Operational Mode to 802 11a/n or 802 11g/n (Refer Properties)
: To configure VAP in WDS-Legacy Mode, the Current Bandwidth must be set to 20 Mhz.
2. Then, navigate to Configuration > Wireless > Interface 1 / Interface 2 > VAP.
3. Select the VAP Type as WDS-Legacy, WDS-END A or WDS-END B from the drop down menu and click OK.
4. The configuration screens (WDS-legacy or WDS-11n, as selected) appear:
