by placing a second access point closer to second group of stations (“Poolside” in our
example) and bridge the two APs with a WDS link. This extends your network wirelessly
by providing an extra hop to get to distant stations.
Backup links and unwanted loops in WDS bridges
Another use for WDS bridging, the creation of backup links, is not supported in this release
of the Gateway 7001 Series self-managed AP. The topic is included here to emphasize that
you should not try to use WDS in this way. Backup links will result in unwanted, endless
loops of data traffic
If an access point provides Spanning Tree Protocol (STP), WDS can be used to configure
backup paths between access points across the network. For example, between two access
points you could have both a primary path through Ethernet and a secondary (backup)
wireless path through a WDS link. If the Ethernet connection goes down, STP would
reconfigure its map of the network and effectively fix the down network segment by
activating the backup wireless path.
The Gateway 7001 Series self-managed AP does not provide STP for this release. Without
STP, it is possible that both connections (paths) may be active at the same time, and result
in an endless loop of traffic on the LAN.
Therefore, be sure not create loops with either WDS bridges or combinations of Wired
(Ethernet) connections and WDS bridges.
For more information, see the “Do not create loops” note under “Configuring WDS
settings” on page 117.
