WDS is part of the autonomous AP control and scaling mechanism. WDS is a software component in supporting Cisco IOS versions and is an access point based Layer 2 solution.
In the WDS Layer 2 architecture, the WDS is a wireless AP. The WLAN Control Domain is one VLAN, which must contain both the WDS AP and the registered wireless APs. Some scaling factors must be considered though, such as having only one active WDS per IP subnet, even though multiple backup WDSs can be defined; a WDS AP serving clients can support 30 member APs; and a dedicated WDS AP can support 60 member APs.
