转帖官网对这几个模式的解释:
Wireless Mode: specifies the operating mode of the device. The mode depends on the network topology requirements. There are 4 operating modes supported in AirOS v5.3 software:
1. Station: This is a client mode, which can connect to an AP.
It is common for a bridging application to an AP. In Station mode device acts as the Subscriber Station while connecting to the Access Point, which is primary defined by the SSID and forwarding all the traffic to/from the network devices connected to the Ethernet interface.
The specifics of this mode is that Subscriber Station is using arpnat technique which may result lack of transparency while passing-through broadcast packets in bridge mode.
2. Station WDS: WDS stands for Wireless Distribution System. Station WDS should be used while connecting to the Access Point, which is operating in WDS mode. This mode is compatible with WPA/WPA2 encryption.
Station WDS mode enables packet forwarding at layer 2 level.
The benefit of Station WDS is improved performance and faster throughput. Station WDS - Bridge mode is fully transparent for all the Layer2 protocols.
Refer to the section Network Settings for detailed Bridge network mode configuration information.
3. Access Point: This is an 802.11 Access Point
4. Access Point WDS: This is an 802.11 Access Point which allows for layer 2 bridging with Station WDS devices using the WDS protocol. AP WDS is not fully compatible with WPA/WPA2 encryption.
WDS allows you to bridge wireless traffic between devices that are operating in Access Point mode. Access Point is usually connected to a wired network (Ethernet LAN) allowing wireless connection to the wired network. By connecting Access Points to one another in an Extended Service Set using the WDS, distant Ethernets can be bridged into a single LAN.
It is very important that network loops should not be created with either WDS bridges or combinations of wired (Ethernet) connections and WDS bridges. Tree or Star shape network topology should be used in all WDS use-cases (i.e. if AP2 and AP3 are specified as the WDS peers of AP1, AP2 should not be specified as the WDS peer of AP3 and AP3 should not be specified as the WDS peer of AP2 in any case). Mesh and Ring network topologies are not supported by WDS and should be avoided in all the use cases.
Note: Station WDS and AP WDS mode uses the WDS protocol that is not defined as the standard thus compatibility issues between equipment from different vendors may arise.
Note: When connecting devices in AP-WDS-to-AP-WDS mode, the WPA/WPA2 security methods will not function. When connecting AP-WDS devices to another AP-WDS device use none or the WEP security method. However, this may compromise the security of your network. In case of connecting STA-WDS clients to an AP-WDS device, all security methods are available and work properly. |
