Wireless Controller
The WDS AP group consists of two types of APs: root APs and satellite APs. A root
AP acts as a bridge or repeater on the wireless medium and communicates with the
controller via the wired link. A satellite AP communicates with the controller via a
WDS link to the root AP. The WDS links are secured using WPA2 Personal
authentication and AES encryption.
Support for the WDS-managed AP feature within the Unified Wired and Wireless
Access System includes the following:

The wireless system can contain up to two WDS -managed AP groups.

Each WDS-managed AP group can contain up to four APs.

An AP can be a member of only one WDS AP group.

Each satellite AP can have only one WDS link on the satellite APs. This means
that a satellite AP must be connected to a root AP. A satellite AP cannot be
connected to another satellite AP.
By default, an AP is configured as a root AP. For an AP to be attached to the Wireless
System as a satellite AP, configure the follo wing settings on the AP while it is in stand -
alone mode:
Satellite AP mode: This setting enables the satellite AP to discover and establish WDS
link with the root AP. By default, the WDS Managed Mode is Root AP.
Password: This is for WPA2 Personal authentication used to establish the WDS links.
Only the satellite APs need this setting. The root APs get the password from the
controller when they become managed.
Static Channel: The APs on each end of a WDS link must use the same radio and
channel to communicate. Configure the satellite AP to use a static channel. For a root
AP, set the static channel when you add the AP to the Valid AP database on the
controller.
Optionally, to allow the Ethernet port on a satellite AP to provide wired access to the
LAN, you must set the WDS Managed Ethernet Port to Enabled. It is disabled by
default.
WDS configuration is divided into three sections: Group, AP, and Link configurat ion.
