Техническая Инструкция для Cisco Cisco 2000 Series Wireless LAN Controller

Set the WLC to be in Layer 3 mode.

1. 

Reboot and give the AP manager interface an IP address in the same subnet as the management
interface.

If you have a service port, such as the service port on a 4402 or 4404, you should have it in a different
supernet than the AP manager and management interfaces.

2. 

You see this error during the upgrade:

FAILED   Unable to Load  the LWAPP Recovery Image on to the AP

When you see this error, complete these steps:

Verify that your TFTP server is properly configured.

If you use the Upgrade Tool embedded TFTP server, a common culprit is personal firewall software,
which blocks the incoming TFTP.

1. 

Check if you are using the correct image for the upgrade.

The upgrade to lightweight mode requires a special image and does not work with the normal upgrade
images.

2. 

You receive this error message on the AP after the conversion:

*Mar 1 00:00:23.535: %LWAPP−5−CHANGED: LWAPP changed state to DISCOVERY 

*Mar 1 00:00:23.550: LWAPP_CLIENT_ERROR_DEBUG: lwapp_crypto_init_ssc_keys_and_

                     certs no certs in the SSC Private File 

*Mar 1 00:00:23.550: LWAPP_CLIENT_ERROR_DEBUG: 

*Mar 1 00:00:23.551: lwapp_crypto_init: PKI_StartSession failed 

*Mar 1 00:00:23.720: %SYS−5−RELOAD: Reload requested by LWAPP CLIENT. 

                     Reload Reason: FAILED CRYPTO INIT. 

*Mar 1 00:00:23.721: %LWAPP−5−CHANGED: LWAPP changed state to DOWN

The AP reloads after 30 seconds and starts the process over again.

Complete this step:

You have an SSC AP. Once you convert to LWAPP AP, add the SSC and its MAC address under the AP
Authentication list in the controller.

These tips can be used when you upgrade from autonomous to LWAPP mode:

If the NVRAM is not cleared when the controller tries to write to it after the conversion, problems are
caused. Cisco recommends to clear the configuration before you convert an AP to LWAPP. In order
to clear the configuration:
