Chapter 1 Overview
Hardware Features
RAP. In order to be considered a RAP, the access point must be configured as a RAP. A RAP is a parent
node to any bridging or mesh network. A controller can support one or more 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 and 5 GHz band. Client
access on 5 GHz is called universal client access.
When the access point does not have a wired Ethernet, fiber-optic, or cable connection to the controller,
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 with an Ethernet or cable connection through a switch to the
controller. MAPs can 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. Depending on the version of software being
used, these links can utilize either 2.4 GHz or 5 GHz as of (8.2.100 and above) to bridge to another access
point to reach a wired network connection to a controller (see
Figure 1-13 ). 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. Control And
Provisioning of Wireless Access Points (CAPWAP) control traffic is also transferred over this bridged
link.
