Architecture Overview
Universal Access
You can configure the backhaul on mesh access points to accept client traffic over its 802.11a radio. This
feature is identified as Backhaul Client Access in the controller GUI (Monitor > Wireless). When this
feature is disabled, backhaul traffic is transmitted only over the 802.11a radio and client association is
allowed only over the 802.11b/g radio. For more information about the configuration, see the

Architecture Overview
This section describes the architecture overview of a mesh network.
CAPWAP
CAPWAP is the provisioning and control protocol used by the controller to manage access points (mesh
and non-mesh) in the network. In release 5.2, CAPWAP replaced LWAPP.
and non-mesh) in the network. In release 5.2, CAPWAP replaced LWAPP.
Upgrading from an earlier LWAPP release (4.1.x.x or earlier) to release 5.2 is transparent. CAPWAP
supports path maximum transmission unit (MTU) discovery and it is configurable on switches and
routers in the backbone network.

routers in the backbone network.
Note
Mesh features are not supported on controller releases 5.0 and 5.1.
CAPWAP is becoming the protocol of choice to manage access points. It significantly reduces capital
expenditures (CapEx) and operational expenses (OpEx), enabling the Cisco wireless mesh networking
solution to be a cost-effective and secure deployment option in enterprise, campus, and metropolitan
networks.

CAPWAP Discovery on a Mesh Network
CAPWAP discovery on a mesh network follows these steps:
1.
A mesh access point establishes a link before starting CAPWAP discovery, whereas a non-mesh
access point starts CAPWAP discovery using a static IP for the mesh access point, if any.
