Chapter 7 Controlling Lightweight Access Points

Autonomous Access Points Converted to Lightweight Mode

Follow these steps to retrieve the radio core dump file using the controller CLI.

Step 1 To transfer the radio core dump file from the access point to the controller, enter this command:

config ap crash-file get-radio-core-dump slot Cisco_AP

For the slot parameter, enter the slot ID of the radio that crashed.

Step 2 To verify that the file was downloaded to the controller, enter this command:

show ap crash-file

Information similar to the following appears:

Local Core Files:

lrad_AP1130.rdump0 (156)

The number in parentheses indicates the size of the file. The size should be greater than zero if a core

dump file is available.

Step 3 To transfer the file from the controller to a TFTP server, enter these commands:

transfer upload datatype radio-core-dump

transfer upload filename filename

transfer upload serverip tftp_server_ip

transfer upload start

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}

• 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.

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:

• 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.
