2 This document describes how to use the Control And Provisioning of Wireless
3 Access Points (CAPWAP) feature in OpenDaylight. This document contains
4 configuration, administration, and management sections for the feature.
7 CAPWAP feature fills the gap OpenDaylight Controller has with respect to managing
8 CAPWAP compliant wireless termination point (WTP) network devices present
9 in enterprise networks. Intelligent applications (e.g. centralized firmware
10 management, radio planning) can be developed by tapping into the
11 WTP network device's operational states via REST APIs.
13 === CAPWAP Architecture
14 The CAPWAP feature is implemented as an MD-SAL based provider module, which
15 helps discover WTP devices and update their states in MD-SAL operational datastore.
17 === Scope of CAPWAP Project
18 In the Lithium release, CAPWAP project aims to only detect the WTPs and store their
19 basic attributes in the operational data store, which is accessible via REST
23 To install CAPWAP, download OpenDaylight and use the Karaf console to install
24 the following feature:
28 === Configuring CAPWAP
30 As of Lithium, there are no configuration requirements.
32 === Administering or Managing CAPWAP
34 After installing the odl-capwap-ac-rest feature from the Karaf console, users
35 can administer and manage CAPWAP from the APIDOCS explorer.
37 Go to http://${IPADDRESS}:8181/apidoc/explorer/index.html, sign in, and expand
38 the capwap-impl panel. From there, users can execute various API calls.
42 ==== Viewing Discovered WTPs
45 This tutorial can be used as a walk through to understand the steps for
46 starting the CAPWAP feature, detecting CAPWAP WTPs, accessing the
47 operational states of WTPs.
50 It is assumed that user has access to at least one hardware/software based CAPWAP
51 compliant WTP. These devices should be configured with OpenDaylight controller
52 IP address as a CAPWAP Access Controller (AC) address. It is also assumed that
53 WTPs and OpenDaylight controller share the same ethernet broadcast domain.
56 . Run the OpenDaylight distribution and install odl-capwap-ac-rest from the Karaf console.
57 . Go to http://${IPADDRESS}:8181/apidoc/explorer/index.html
59 . Click /operational/capwap-impl:capwap-ac-root/
61 . The above step should display list of WTPs discovered using ODL CAPWAP feature.
