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: The VAP provides services to clients as a normal access
◆
point.
WDS-AP Mode: The VAP operates as an access point in WDS mode,
◆
which accepts connections from client stations in WDS-STA mode.
WDS-STA Mode: The VAP operates as a client station in WDS mode,
◆
which connects to an access point VAP in WDS-AP mode. The user
needs to specify the MAC address of the VAP in WDS-AP mode to which
it intends to connect.
