Configuring Hybrid REAP
•
The controller can send multicast packets in the form of unicast or multicast packets to the access
point. In hybrid-REAP mode, the access point can receive multicast packets only in unicast form.
•
To use CCKM fast roaming with hybrid-REAP access points, you need to configure hybrid-REAP
groups. See the
“Configuring Hybrid-REAP Groups” section on page 13-15
for more information.
•
Hybrid-REAP access points support a 1-1 network address translation (NAT) configuration. They
also support port address translation (PAT) for all features except true multicast. Multicast is
supported across NAT boundaries when configured using the Unicast option. Hybrid-REAP access
points also support a many-to-one NAT/PAT boundary, except when you want true multicast to
operate for all centrally switched WLANs.
Note
Although NAT and PAT are supported for hybrid-REAP access points, they are not supported
on the corresponding controller. Cisco does not support configurations in which the
controller is behind a NAT/PAT boundary.
•
VPN and PPTP are supported for locally switched traffic, provided that these security types are
accessible locally at the access point.
•
Hybrid-REAP access points support multiple SSIDs. Refer to the
“Using the CLI to Create WLANs”
for more information.
•
NAC out-of-band integration is supported only on WLANs configured for hybrid-REAP central
switching. It is not supported for use on WLANs configured for hybrid-REAP local switching. Refer
to the
“Configuring NAC Out-of-Band Integration” section on page 6-55
for more information.
•
The primary and secondary controllers for a hybrid-REAP access point must have the same
configuration. Otherwise, the access point might lose its configuration, and certain features (such as
WLAN override, AP group VLANs, static channel number, and so on) might not operate correctly.
In addition, make sure to duplicate the SSID of the hybrid-REAP access point and its index number
on both controllers.
Configuring Hybrid REAP
To configure hybrid REAP, you must follow the instructions in these sections in the order provided:
•
Configuring the Switch at the Remote Site, page 13-5
•
Configuring the Controller for Hybrid REAP, page 13-6
•
Configuring an Access Point for Hybrid REAP, page 13-11
•

Configuring the Switch at the Remote Site
Follow these steps to prepare the switch at the remote site.
Step 1
Attach the access point that will be enabled for hybrid REAP to a trunk or access port on the switch.
Note
The sample configuration below shows the hybrid-REAP access point connected to a trunk port
on the switch.
