客户端station选择不同的模式，兼容情况如下表
ROS802.11，nstreme,nv2说明必须双边都是ROS设备
Applicability Matrix
The following matrix specifies station modes available for each wireless-protocol. Note that there are 2 columns for 802.11 protocol: 802.11 specifies availability of mode in "pure" 802.11 network (when connecting to any vendor AP) and ROS 802.11 specifies availability of mode when connecting to RouterOS AP that implements necessary proprietary extensions for mode to work.
Table applies to RouterOS v5rc11 and above:
| 802.11 | ROS 802.11 | nstreme | nv2 | |
|---|---|---|---|---|
| station | V | V | V | V |
| station-wds | V | V | V | |
| station-pseudobridge | V | V | V | |
| station-pseudobridge-clone | V | V | V | |
| station-bridge | V | V | V |
Mode station
This is standard mode that does not support L2 bridging on station - attempts to put wireless interface in bridge will not produce expected results. On the other hand this mode can be considered the most efficient and therefore should be used if L2 bridging on station is not necessary - as in case of routed or MPLS switched network. This mode is supported for all wireless protocols.
Mode station-wds
This mode works only with RouterOS APs. As a result of negotiating connection, separate WDS interface is created on AP for given station. This interface can be thought of point-to-point connection between AP and given station - whatever is sent out WDS interface is delivered to station (and only to particular station) and whatever station sends to AP is received from WDS interface (and not subject to forwarding between AP clients), preserving L2 addresses.
This mode is supported for all wireless protocols except when 802.11 protocol is used in connection to non-RouterOS device. Mode uses 4 address frame format when used with 802.11 protocol, for other protocols (such as nstreme or nv2), protocol internal means are used.
This mode is safe to use for L2 bridging and gives most administrative control on AP by means of separate WDS interface, for example use of bridge firewall, RSTP for loop detection and avoidance, etc.
With station-wds mode, it is not possible to connect to CAPsMAN controlled CAP.
Mode station-pseudobridge
From the wireless connection point of view, this mode is the same as standard station mode. It has limited support for L2 bridging by means of some services implemented in station:
- MAC address translation for IPv4 packets - station maintains IPv4-to-MAC mapping table and replaces source MAC address with its own address when sending frame to AP (in order to be able to use 3 address frame format), and replaces destination MAC address with address from mapping table for frames received from AP. IPv4-to-MAC mappings are built also for VLAN encapsulated frames.
- single MAC address translation for the rest of protocols - station learns source MAC address from first forwarded non-IPv4 frame and uses it as default for reverse translation - this MAC address is used to replace destination MAC address for frames received from AP if IPv4-to-MAC mapping can not be performed (e.g. - non-IPv4 frame or missing mapping).
This mode is limited to complete L2 bridging of data to single device connected to station (by means of single MAC address translation) and some support for IPv4 frame bridging - bridging of non-IP protocols to more than one device will not work. Also MAC address translation limits access to station device from AP side to IPv4 based access - the rest of protocols will be translated by single MAC address translation and will not be received by station itself.
This mode is available for all protocols except nv2 and should be avoided when possible. The usage of this mode can only be justified if AP does not support better mode for L2 bridging (e.g. when non-RouterOS AP is used) or if only one end-user device must be connected to network by means of station device.
Mode station-pseudobridge-clone
This mode is the same as station-pseudobridge mode, except that it connects to AP using "cloned" MAC address - that is either address configured in station-bridge-clone-mac parameter (if configured) or source address of first forwarded frame. This essentially appears on AP as if end-user device connected to station connected to AP.
Mode station-bridge
This mode works only with RouterOS APs and provides support for transparent protocol-independent L2 bridging on the station device. RouterOS AP accepts clients in station-bridge mode when enabled using bridge-mode parameter. In this mode, the AP maintains a forwarding table with information on which MAC addresses are reachable over which station device.
This mode is MikroTik proprietary and cannot be used to connect to other brands of devices.
This mode is safe to use for L2 bridging and is the preferred mode unless there are specific reasons to use station-wds mode. With station-bridge mode, it is not possible to connect to CAPsMAN controlled CAP.
