Chapter 7 Controlling Lightweight Access Points
Autonomous Access Points Converted to Lightweight Mode
Controllers Accept SSCs from Access Points Converted to Lightweight Mode
The lightweight access point protocol (LWAPP) secures the control communication between the access point and controller by means of a secure key distribution requiring X.509 certificates on both the access point and controller. LWAPP relies on a priori provisioning of the X.509 certificates. Factory installed certificates are referenced by the term MIC, which is an acronym for
Using DHCP Option 43
Cisco 1000 series access points use a string format for DHCP option 43, whereas Cisco Aironet access points use the
Table
Access Point | VCI String |
|
|
Cisco 1000 Series | Airespace 1200 |
|
|
Cisco Aironet 1130 Series | Cisco AP c1130 |
|
|
Cisco Aironet 1200 Series | Cisco AP c1200 |
|
|
Cisco Aironet 1240 Series | Cisco AP c1240 |
|
|
This is the format of the TLV block:
•Type: 0xf1 (decimal 241)
•Length: Number of controller IP addresses * 4
•Value: List of the IP addresses of controller management interfaces
Refer to the product documentation for your DHCP server for instructions on configuring DHCP Option
43.The Application Note: Upgrading Autonomous Cisco Aironet Access Points To Lightweight Mode contains example steps for configuring option 43 on a DHCP server.
Using a Controller to Send Debug Commands to Access Points Converted to Lightweight Mode
Enter this command to enable the controller to send debug commands to an access point converted to lightweight mode:
config ap
When this feature is enabled, the controller sends debug commands to the converted access point as character strings. You can send any debug command supported by Cisco Aironet access points that run Cisco IOS software in lightweight mode.
