AP-Server Mutual Authentication
The AP-server communication begins with a mutual authentication step when the AP and server authenticate each other using a shared secret. The AP-server communication takes place only if this authentication succeeds.
After the authentication succeeds, the server generates a session key, and encrypts all communication between the AP and server.
The AP and server ship with the same default value for the shared secret. Change the shared secret using the CLI on the server and the AP.
Note: After changing the shared secret (communication key) on the server, all APs connected to the server automatically use the new communication key. You must manually configure the new communication key on an AP not connected to the server when the key changes on the server.
Note:Although the server is backward compatible, older version APs can connect to a newer version server, but not recommended.
