Wireless Distribution System (WDS) is a wireless method of configuring a network backbone between WL520 devices, and
functions much like Ethernet. Using wireless cards, WDS allows you to configure up to six (6) point-to-point links between
Access Point devices.
NOTE:
This feature is only applicable to 2.4 GHz (802.11b) cards.

Each wireless card can support up to six WDS links, and each link is mapped to a logical port on the WL520 (WDS ports).
WDS ports behave like Ethernet ports on the WL520 but BSS ports are handled differently: the WL520 learns by association
on BSS ports and from frames on WDS/Ethernet ports.
WL520 Ports:
1. Ethernet Port
2. BSS Port (Wireless Card A)
3-8. WDS ports for Wireless Card A
9. BSS Port (Wireless Card B)
10-15. WDS Ports for Wireless Card B
NOTE:
The above assumes that the WL520 has two 802.11b cards installed.

Q
The state of each WDS port in the bridge/spanning tree can be controlled from two places:
802.11 MIB WDS table
Bridge MIB port table
Q
If you are only using one card, always place it in Slot A.
Q
Spanning tree determines the port states if WDS configurations are correct.
Q
If there is no partner MAC address configured in the WDS table, the WDS port remains disabled.
Q
No two partner MAC addresses should be the same for WDS ports on the same card.
Q
Channel settings on the cards should be the same.
