Overview of Hybrid REAP
Overview of Hybrid REAP
Hybrid REAP
is a solution for branch office and remote office deployments. It enables customers to
configure and control two or three access points in a branch or remote office from the corporate office
through a wide area network (WAN) link without deploying a controller in each office.
Note
In release 4.0.206.0 and greater, Hybrid REAP can be used with up to eight access points.
The hybrid-REAP access points can switch client data traffic locally and perform client authentication
locally when their connection to the controller is lost. When they are connected to the controller, they
can also send traffic back to the controller.
Hybrid REAP is supported only on the 1130AG and 1240AG access points and on the 2000 and 4400
series controllers, the Catalyst 3750G Integrated Wireless LAN Controller Switch, the Cisco WiSM, and
the Controller Network Module for Integrated Services Routers.

Hybrid-REAP Authentication Process
When a hybrid-REAP access point boots up, it looks for a controller. If it finds one, it joins the controller,
downloads the latest software image and configuration from the controller, and initializes the radio. It
saves the downloaded configuration in non-volatile memory for use in standalone mode.
A hybrid-REAP access point can learn the controller IP address in one of these ways:
•
If the access point has been assigned an IP address from a DHCP server, it can discover a controller
through the regular LWAPP discovery process [Layer 3 broadcast, over-the-air provisioning
(OTAP), DNS, or DHCP option 43].
Note
OTAP does not work on the first boot out of the box.
