Controlling Lightweight Access Points

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.
On the controller CLI, enter this command to pull the core file from the access point:
config ap get-radio-core-dump slot ap-name
For slot, enter the radio interface number on 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.

Enabling Memory Core Dumps from Converted Access Points

By default, access points converted to lightweight mode do not send memory core dumps to the
controller. To enable this feature, enter this command:
config ap core-dump enable tftp-server-ip-address filename {compress | uncompress} {ap-name | all}

Display of MAC Addresses for Converted Access Points

There are some differences in the way that controllers display the MAC addresses of converted access
points on information pages in the controller GUI:
OL-9141-03
For tftp-server-ip-address, enter the IP address of the TFTP server to which the access point sends
core files. The access point must be able to reach the TFTP server.
For filename, enter a filename that the access points uses to label the core file.
Enter compress to configure the access point to send compressed core files. Enter uncompress to
configure the access point to send uncompressed core files.
For ap-name, enter the name of a specific access point, or enter all to enable memory core dumps
from all access points converted to lightweight mode.
On the AP Summary page, the controller lists the Ethernet MAC addresses of converted access
points.
On the AP Detail page, the controller lists the BSS MAC addresses and Ethernet MAC addresses of
converted access points.
On the Radio Summary page, the controller lists converted access points by radio MAC address.
