When using Spanning Tree to configure WDS links, you must first configure the MAC address of the card to which the wireless
link will be established. Data transmitted on the WDS port goes directly, via point-to-point link, to the MAC address of the
wireless card you configure.
NOTE:
Since six (6) WDS ports can be configured for each card, you need to map paths from WDS ports to mutually
exclusive wireless port designations for Spanning Tree.

This configuration requires two or three WL520 devices. If you have three devices, a dedicated wireless WL520 unit should be
configured with Slot A and Slot B of the WL520 device wireless distribution link. This WL520 unit should not be connected to
a wired interface. Please note: A slot may repeat up to six wired links. Also, the other two wired WL520 units should be
configured so that one slot partners with the Wireless WDS partner.
If you have two devices, form a WDS link between them by configuring one wireless card in each WL520 as a dedicated
WDS port.
Additional Information: The WL520 unit should only allow client associations on those channels and network names that are
configured for a WDS link.
Result: The wireless WL520 unit functions as a repeater.

This section contains additional information about the WL520’s interaction with your network’s RADIUS servers.
fallback to primary radius server fallback to primary radius server fallback to primary radius server fallback to primary radius server
This automatic feature ensures the primary RADIUS server is used to authenticate your network when it is available. If you have
configured the WL520 with a primary and a backup RADIUS server, the WL520 will switch to the backup server if the primary
server fails for any reason. After the unit has switched to the backup server, it will periodically check the status of the primary
RADIUS server every five (5) minutes. Once the primary RADIUS server is again online, the WL520 automatically reverts from
the backup RADIUS server back to the primary RADIUS server. All subsequent requests are sent to the primary RADIUS server.

Using an external RADIUS server, the WL520 can track and record the length of client sessions on the access point by sending
RADIUS accounting messages per RFC2866. When a wireless client is successfully authenticated, RADIUS accounting is
initiated by sending an “Accounting Start” request to the RADIUS server. When the wireless client session ends, an
“Accounting Stop” request is sent to the RADIUS server.
