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:

debug ap {enable | disable | command cmd} Cisco_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.

Converted Access Points Send Crash Information to Controller

When a converted access point unexpectedly reboots, the access point stores a crash file on its local flash

memory at the time of crash. After the unit reboots, it sends the reason for the reboot to the controller.

If the unit rebooted because of a crash, the controller pulls up the crash file using existing LWAPP

messages and stores it in the controller flash memory. The crash info copy is removed from the access

point flash memory when the controller pulls it from the access point.

Converted Access Points Send Radio Core Dumps to Controller

When a radio module in a converted access point generates a core dump, the access point stores the core

dump file of the radio on its local flash memory at the time of the radio crash. It sends a notification

message to the controller indicating which radio generated a core dump file. The controller sends a trap

alerting the network administrator, and the administrator can retrieve the radio core file from the access

point.

The retrieved core file is stored in the controller flash and can subsequently be uploaded through TFTP

to an external server for analysis. The core file is removed from the access point flash memory when the

controller pulls it from the access point.
