RAPs, each one parenting the same or different wireless networks. There can be more than one RAP
for the same mesh network for redundancy. RAPs and MAPs can support wireless clients on the
2.4-GHz band.
When the access point does not have a wired Ethernet connection to the controller (through a switch),
the radio role is called a MAP. The MAPs have a wireless connection (through the backhaul interface)
to other MAPs and finally to a RAP which has an Ethernet connection through a switch to the
controller. MAPs may also have a wired Ethernet connection to a local LAN and serve as a bridge
endpoint for that LAN (using a point-to-point or point-to-multipoint bridge connection).
Wireless Backhaul
The access point supports wireless backhaul capability using the 5-GHz radio to bridge to another
access point to reach a wired network connection to a controller as shown in Figure 4. The access point
connected to the wired network is considered a RAP in this configuration. The remote access point is
considered a MAP and transfers wireless client traffic to the RAP for transfer to the wired network.
Lightweight access point protocol (LWAPP) control traffic is also transferred over this bridged link.

Point-to-Point Bridging
The access points can be used to extend a remote network by using the 5-GHz backhaul radio to bridge
the two network segments as shown in Figure 5. To support Ethernet bridging, you must enable
bridging on the controller for each access point.
Wireless client access is supported; however, if bridging between tall buildings, the 2.4-Ghz wireless
coverage area may be limited and possibly not suitable for direct wireless client access.
