The IEEE 802.11 standard defines a Wireless Distribution System (WDS)
for bridge connections between BSS areas (access points). The access
point uses WDS to forward traffic on links between units.
The access point supports WDS bridge links that are independently
configurable on each VAP. There are two WDS modes; WDS-AP and WDS-
STA. Otherwise, VAPs operate in a normal AP mode.
◆
AP Mode: Provides services to clients as a normal access point.
◆
WDS-AP Mode: Operates as an access point in WDS mode, which
accepts connections from client stations in WDS mode.
◆
WDS-STA Mode: Operates as a client station in WDS mode, which
connects to an access point in WDS mode. The user needs to specify
the MAC address of the access point in WDS mode to which it intends to
connect.
