Caution This command disables password recovery. If you lose the privileged EXEC mode password for the
access point after entering this command, you will need to contact the Cisco Technical Assistance Center
(TAC) to regain access to the access point command line interface (CLI).
Note To reboot the wireless device, use the service-module wlan-ap reset command from the Cisco IOS CLI.
See the “Rebooting the Wireless Device” section on page 314 for information about this command.
The mode button is enabled by default. To disable the access point’s mode button, Follow these steps,
beginning in privileged EXEC mode.
SUMMARY STEPS
1. configure terminal
2. no boot mode-button
3. end
DETAILED STEPS
You can check the status of the mode button by executing the show boot or show boot mode-button
command in privileged EXEC mode. The status does not appear in the running configuration. The
following shows typical responses to the show boot and show boot mode-button commands:
ap# show boot
BOOT path-list: flash:/c1200-k9w7-mx-v123_7_ja.20050430/c1200-k9w7-mx.v123_7_ja.20050430
Config file: flash:/config.txt
Private Config file: flash:/private-config
Enable Break: no
Manual boot:no
Mode button:on
Enable IOS break: no
