CAPWAP Discovery and Management, Managed AP Finds the Controller, Manual

Page 76 highlights

Chapter 6 Network Figure 42 CAPWAP Network Example Note: The NWA/WAC can be a standalone AP (default), or a CAPWAP managed AP. CAPWAP Discovery and Management The link between CAPWAP-enabled access points proceeds as follows: 1 An AP in managed AP mode joins a wired network (receives a dynamic IP address). 2 The AP sends out a discovery request, looking for a CAPWAP AP controller. 3 If there is an AP controller on the network, it receives the discovery request. If the AP controller is in Manual mode it adds the details of the AP to its Unmanaged Access Points list, and you decide which available APs to manage. If the AP controller is in Always Accept mode, it automatically adds the AP to its Managed Access Points list and provides the managed AP with default configuration information, as well as securely transmitting the DTLS pre-shared key. The managed AP is ready for association with wireless clients. Managed AP Finds the Controller A managed NWA/WAC can find the controller in one of the following ways: • Manually specify the controller's IP address in the Web Configurator's AC (AP Controller) Discovery screen. • Get the controller's IP address from a DHCP server with the controller's IP address configured as option 138. • Get the controller's IP address from a DNS server SRV (Service) record.

CAPWAP Network Example
Note: The NWA/WAC can be a standalone AP (default), or a CAPWAP managed AP.
CAPWAP Discovery and Management
The link between CAPWAP-enabled access points proceeds as follows:
1
An AP in managed AP mode joins a wired network (receives a dynamic IP address).
2
The AP sends out a discovery request, looking for a CAPWAP AP controller.
3
If there is an AP controller on the network, it receives the discovery request. If the AP controller is in
Manual
mode it adds the details of the AP to its
Unmanaged Access Points
list, and you decide which
available APs to manage. If the AP controller is in
Always Accept
mode, it automatically adds the AP to
its
Managed Access Points
list and provides the managed AP with default configuration information, as
well as securely transmitting the DTLS pre-shared key. The managed AP is ready for association with
wireless clients.
Managed AP Finds the Controller
A managed NWA/WAC can find the controller in one of the following ways:
Manually specify the controller’s IP address in the Web Configurator’s
AC
(AP Controller)
Discovery
screen.
Get the controller’s IP address from a DHCP server with the controller’s IP address configured as
option 138.
Get the controller’s IP address from a DNS server SRV (Service) record.
