How to recover the hash key off the Access Point and import it onto the controller.
The Lightweight Access Point Protocol (LWAPP) conversion tool saves a key hash file on the PC running the conversion application.
SHA1 Key Hash key can be found in the file stored in Comma-Separated Values (CSV) format in the Upgrade Tool directory. This is an example:
C:\Program File\Cisco Systems\Upgrade Tool
The file is in CSV format.
Perform these steps on the controller:
Go to Security > AP Policies > Accept Self Signed Certificate (check box).
Add these under the Access Point (AP) authorization list:
- The MAC address of the AP
- The certificate type
- SHA1 Key Hash (The key can be found in the file stored in CSV format in the Upgrade Tool directory.)
Enable Accept Self Signed Certificate
