Figure 28: WDS Example
Bridging WDS
Each WDS link is mapped to a logical WDS port on the AP. WDS ports behave like Ethernet
ports rather than like standard wireless interfaces: on a BSS port, an Access Point learns by
association and from frames; on a WDS or Ethernet port, an Access Point learns from frames
only. When setting up a WDS, keep in mind the following:
There are separate security settings for clients and WDS links. The same WDS link
•
security mode must be configured (currently the AP supports only none or WEP) on each
Access Point in the WDS and the same WEP key must be configured.
The WDS link shares the communication bandwidth with the clients. Therefore, while the
•
maximum data rate for the Access Point's cell is 54 Mbits/second (802.11a, 802.11g only,
or 802.bg modes) or 11 Mbits/second (802.11b only mode), client throughput will decrease
when the WDS link is active.
If there is no partner MAC address configured in the WDS table, the WDS port remains
•
disabled.
Each WDS port on a single AP should have a unique partner MAC address. Do not enter
•
the same MAC address twice in an AP's WDS port list.
Each Access Point that is a member of the WDS must have the same Channel setting to
•
communicate with each other.
If your network does not support spanning tree, be careful to avoid creating network loops
•
between APs. For example, creating a WDS link between two Access Points connected to
the same Ethernet network will create a network loop (if spanning tree is disabled). For
more information, see
