Cisco Cisco Aironet 1522 Lightweight Outdoor Mesh Access Point Guía De Diseño

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 

This section describes the architecture overview of a mesh network.

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.

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.

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 follows these steps:

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.
