Instead, you can utilize an AP architecture where the traditional LWAPP control plane is leveraged in order to
perform tasks, such as dynamic configuration management, AP software upgrade, and wireless intrusion
detection. This allows wireless data to remain local, and the wireless infrastructure to be centrally managed
and resilient to WAN outage.

1030 REAP Architecture Introduction
The Cisco 1030 REAP separates the LWAPP control plane from the wireless data plane in order to provide
remote functionality. Cisco WLCs are still used for centralized control and management in the same way as
regular LAPs. The difference is that all user data is bridged locally at the AP. Access to local network
resources is maintained throughout WAN outages. Figure 1 illustrates a basic REAP architecture.

Note: See Appendix A for a list of basic differences in REAP functionality as compared to traditional LAPs.
When Should REAP APs be Used?
The Cisco 1030 REAP AP should be used primarily under these two conditions:
If the link between the LAP and WLC is prone to outage, the 1030 REAP can be used to allow
wireless users uninterrupted data access during link failure.
wireless users uninterrupted data access during link failure.
•
If all user data must be terminated locally, which means at the wired port of the AP (as opposed to
being terminated at the controller, as data is for all other LAPs), the 1030 REAP can be used to allow
for central control via the controller interface and/or the Wireless Control System (WCS). This allows
data to remain local.

Where coverage or user density requires more than two or three 1030 REAP APs at a single site, consider the
deployment of a 2006 or 2106 WLC. These controllers can support up to 6 LAPs of any type. This can prove
