When you design or operate a wireless LAN (WLAN), consider the hardware
components capacity to form an association with other elements of the network.
This document describes in simple format the association capabilities of each
Cisco wireless component.
There are no specific requirements for this document.
This document is applicable to all Cisco wireless hardware and software

The 802.11 association process allows an AP to map a logical port or
association identifier (AID) to the wireless station. The association process
is initiated by the wireless station with an association request frame
containing the capability information of the client and completed by the AP in
an association response frame. The association response indicates success or
failure as well as a reason code.
This matrix considers the configurable capabilities of the different
Cisco Aironet components. For example, because the Cisco Aironet Client Adapter
card can be configured to work in either Infrastructure mode or in Ad Hoc mode,
there is a column and row for each mode.
Note: This matrix does not focus on lightweight and mesh devices. There are
separate sections in this document, Wireless Mesh
Hardware Association and LWAPP APs
Association, that discuss association details of these devices.
In order to determine whether two particular Cisco Aironet components
can form an association, choose one of the components from the columns across
the top of the matrix and choose the other from the rows listed along the left
side of the matrix.
If the two components can form an association, there is an
X where the selected column and row intersect. A blank space
indicates an inability to associate.
CA = Client Adapter
AP = Access Point
BR = Ethernet Bridge
BSx = Base Station
X = association possible
/ = association possible if repeater is associated to "root" AP
The mesh networking solution, which is part of the Cisco Unified
Wireless Network Solution, enables two or more Cisco Aironet Lightweight Mesh
Access Points (hereafter called mesh APs) to communicate with
each other over one or more wireless hops in order to join multiple LANs or to
extend 802.11b wireless coverage. Cisco Mesh APs are configured, monitored, and
operated from and through any Cisco WLAN controller (WLC) deployed in the mesh
Cisco Aironet 1030 Remote Edge Lightweight APs and Cisco Aironet 1500
Series Lightweight Outdoor APs can be deployed as mesh APs.
You can operate the Cisco Aironet 1030 Remote Edge Lightweight APs and
Cisco Aironet 1500 Series Lightweight Outdoor APs in one of these roles:
Here is the Association table for the wireless mesh devices:
Note: Cisco Aironet 1030 Remote Edge Lightweight APs and Cisco Aironet 1500
Series Lightweight Outdoor APs support single-hop deployments. However, Cisco
Aironet 1500 Series Lightweight Outdoor APs are required to support multi-hop

Mesh Networking Solution Deployment Guide for more information.
Lightweight AP Protocol (LWAPP)-enabled APs are part of the Cisco
Integrated Wireless Network Solution and require no manual configuration before
they are mounted. The AP is configured by an LWAPP-capable Cisco WLC.
In the Cisco Centralized WLAN architecture, LWAPP-enabled APs operate
in the lightweight mode (as opposed to the autonomous mode).
LWAPP is an IETF draft protocol that defines the control messaging for
setup and path authentication and run-time operations. LWAPP also defines the
tunneling mechanism for data traffic.
Here is the Association table for the LWAPP
Note: LWAPP APs do not have any relationship with autonomous APs. LWAPP APs
come under centralized WLAN architecture. Whereas, autonomous APs come under
distributed WLAN architecture. In addition to LWAPP APs, there are certain APs
which can act in both LWAPP mode and autonomous mode (not at the same time) if
the appropriate firmware is installed.
